Security Window Grates for Basement Windows: The Complete Protection Guide
Discover why security window grates for basement windows are essential. Compare fixed, removable & egress options. Shop SWB steel grates from $90.
Security Window Bars (SWB), the #1 authority in residential perimeter protection in the USA, brings you the most critical advice to keep your home safe. If you own or rent a home with a basement, your lowest-level windows represent one of the most exploited entry points for residential burglars in the country. According to the FBI Uniform Crime Report, approximately 6.7 million burglaries occur in the United States every year — and security researchers consistently find that ground-floor and below-grade windows account for roughly 60% of all forced entries. Basement windows, often hidden from street view by landscaping or shrubbery, give intruders the cover and time they need. Installing security window grates for basement windows is one of the single most cost-effective deterrents available to American homeowners and renters. This guide walks you through exactly why basement windows are targeted, what types of security window grates exist, how egress compliance affects your choices, and which SWB model fits your situation — whether you own your home or rent it.

Why Basement Windows Are a Top Burglary Target in the USA
Most homeowners instinctively focus security measures on front and back doors, installing deadbolts and alarm sensors while leaving basement windows almost entirely unprotected. That oversight is precisely what career burglars in cities like Chicago, Detroit, Philadelphia, and Houston count on. Basement windows present a unique combination of vulnerability factors that make them disproportionately attractive as entry points. They sit at or below grade level — often partially obscured by window wells, foundation plantings, or privacy fences — meaning an intruder can work at the opening for 60 to 90 seconds without being visible from the street or neighboring properties. Standard residential basement windows are typically small, single-pane, and protected by nothing more than a basic latch that can be defeated with a flathead screwdriver in under five seconds. The National Crime Prevention Council (NCPC) reports that most residential burglars spend fewer than 60 seconds forcing entry; a latched basement window gives them plenty of time. Once inside, a burglar has unrestricted access to the entire home — including sleeping areas, safes, electronics, and garage interior door access. Understanding this threat picture is the essential first step before selecting security window grates for basement windows that are properly rated for the job.
The Concealment Advantage Burglars Exploit
A basement window sitting in a below-grade window well is effectively invisible to anyone passing on the sidewalk. Unlike a first-floor living room window — where the sight of someone tampering would immediately draw attention — a below-grade window well creates a private workspace for a would-be intruder. Mature foundation shrubs, decorative gravel borders, and even parked vehicles can further obscure the view. In densely populated cities such as Baltimore, Memphis, and Atlanta, where homes often sit close together with shared side yards, these concealment pockets are extremely common. Security research published by the University of North Carolina at Charlotte’s Department of Criminal Justice found that 83% of convicted burglars said they would abandon a target if it required too much effort or risk of detection. A heavy-gauge steel security grate mounted over a basement window removes the time advantage entirely.
Why Basic Window Latches Fail Against Forced Entry
The standard latch mechanisms factory-installed on most basement windows — whether awning, hopper, or casement style — are engineered for weatherproofing, not security. They are made of lightweight zinc or aluminum die-cast components that fracture under lateral force. A simple pry bar, large screwdriver, or even a strong kick applied to the exterior frame is sufficient to defeat the latch and swing the window open. In cold-weather climates like Minnesota, Wisconsin, and Michigan, repeated freeze-thaw cycles further weaken window frames and hardware over years of exposure, making forced entry even easier. Security window grates for basement windows address this vulnerability at the structural level — placing a hardened steel barrier in front of the window opening itself rather than relying on the window’s own locking mechanism.
High-Crime Cities Where Basement Window Security Is Critical
The FBI’s Crime Data Explorer identifies consistent patterns in residential burglary concentration across American metropolitan areas. Cities including St. Louis, Cleveland, Kansas City, Albuquerque, and Anchorage regularly appear near the top of property crime rankings. In these markets, homes without visible deterrents — including security bars or grates on basement windows — are statistically more likely to be targeted. Even in lower-crime suburban areas, a visibly secured basement window signals to any opportunistic burglar that this home is hardened and not worth the risk. That deterrence value is as important as the physical stopping power of the steel itself.
Types of Security Window Grates for Basement Windows: Fixed, Removable, and Egress-Compliant
Not all security window grates for basement windows are created equal, and selecting the wrong type can leave you with either inadequate protection or a serious code violation. The three primary categories — fixed wall-mount grates, telescopic removable grates, and egress-compliant quick-release grates — each serve distinct situations depending on whether you own or rent the property, whether the basement is finished and occupied as a sleeping area, and what your local building code requires. Understanding the differences before purchasing is essential, because the wrong choice may either fail to stop a determined intruder or trap your family in an emergency. The International Building Code (IBC) and NFPA 101 Life Safety Code both impose specific requirements on any security grate installed over a window that serves as an emergency egress route, and those requirements are strictly enforced during home inspections, insurance underwriting, and after fire incidents. This section walks through each category clearly so you can make an informed decision.
Fixed Wall-Mount Security Grates: Maximum Strength for Permanent Installations
Fixed wall-mount security grates are anchored directly into the masonry or wood framing surrounding a basement window using heavy-gauge steel hardware. This category delivers the highest baseline resistance to forced entry because the grate cannot flex, slide, or be pried away from the wall without serious demolition-level effort. The SWB Model B — Wall-Mount Window Bars ($91) is built exactly for this application, featuring heavy-gauge steel construction and a powder-coated black finish that resists corrosion in below-grade window well environments where moisture accumulates. Fixed grates are ideal for basement windows in unfinished utility areas, storage rooms, laundry rooms, or any space that is never used as a sleeping area. Homeowners who do not plan to move and want the strongest possible deterrent with no moving parts should prioritize fixed wall-mount installation. Note: fixed grates installed over a window serving as a sleeping-area egress exit require an interior release mechanism to comply with IBC and NFPA 101 — which is where the egress-compliant category becomes mandatory.
Telescopic Removable Security Grates: The Renter-Friendly Solution
For the 44.1 million apartment and home renters in the United States (US Census Bureau, 2023), drilling into concrete or masonry foundation walls to install permanent hardware is often prohibited by the lease agreement and can result in loss of the security deposit. Telescopic removable security grates solve this problem by using internal spring tension or adjustable end brackets to hold the bars firmly in place without requiring permanent fasteners. The SWB Model A — Telescopic Window Bars ($90) fits windows ranging from 22 to 36 inches wide — covering virtually all standard US basement window sizes — and can be installed in 15 to 20 minutes without professional tools. When the lease ends, the entire unit removes cleanly without leaving any trace in the wall. This is particularly valuable for renters in high-crime urban rental markets including New York City, Los Angeles, and Chicago, where landlords routinely resist upgrading security but tenants bear the personal risk of ground-floor and basement window break-ins.
Egress-Compliant Grates: When Basement Bedrooms Require Quick Release
If a finished basement is used as a bedroom, guest room, or any sleeping area, the window in that space is legally designated as an emergency egress exit under the International Residential Code (IRC), IBC Section 1030, and NFPA 101. This means any security grate installed over that window must allow occupants to escape from the inside without tools or keys — even in a smoke-filled emergency. The SWB Model A/EXIT — Egress Compliant Window Bars ($92) features a patented quick-release mechanism that allows any occupant to open the grate from the interior in seconds. It meets IBC, NFPA 101, and OSHA standards while maintaining the full anti-intrusion strength of a solid steel security grate from the exterior. For homeowners in cities like Phoenix, Dallas, and Denver — where finished basements are commonly used as rental suites or in-law units — egress-compliant security window grates for basement windows are not optional. They are required by law, and failure to install them can void your homeowner’s insurance coverage in the event of a fire-related fatality.
Building Code Compliance for Basement Window Security Grates in the USA
One of the most frequently overlooked aspects of installing security window grates for basement windows is navigating the applicable building codes and life safety standards. In the United States, multiple overlapping regulatory frameworks govern what is permissible when adding physical security hardware to a window — and the specific requirements vary significantly depending on the window’s location, the room it serves, and whether the property is residential or commercial. Failing to comply can result in failed home inspections, denied insurance claims, or — in the worst case — a preventable loss of life during a fire or other emergency. The primary codes that govern window security hardware in the USA are the International Building Code (IBC), the International Residential Code (IRC), and NFPA 101: Life Safety Code. OSHA also imposes egress requirements in any space used for employee occupancy. Understanding which code applies to your specific basement window situation before purchasing any security grate is not just smart — it is legally and morally essential.
IBC Section 1030 and IRC Emergency Egress Requirements
Under IBC Section 1030 and its residential counterpart in the IRC, any window that serves as the sole or designated emergency escape and rescue opening (EERO) for a sleeping room must maintain a minimum clear opening of at least 20 inches in width, 24 inches in height, and 5.7 square feet in net open area (5.0 sq ft at grade level). Critically, Section 1030.3 states that bars, grilles, grates, or screens installed over required egress windows must be releasable or removable from the inside without the use of a key, tool, or special knowledge. This provision exists because during a house fire, occupants may be disoriented by smoke and unable to operate a keyed lock. Any fixed security grate that cannot be opened from the inside — regardless of its structural strength — is a code violation on a sleeping-area basement window. The SWB Model A/EXIT is specifically engineered to satisfy this requirement with its patented interior quick-release mechanism.
NFPA 101 Life Safety Code and What It Means for Homeowners
NFPA 101, adopted as the governing life safety standard in most US states and municipalities, expands on IBC egress requirements by addressing occupant load, path of egress travel, and the specific performance characteristics of release hardware. Under NFPA 101 Section 7.2.1, any egress component — including a security grate over a window — must be operable from the egress side without the use of a key or any special knowledge. The release mechanism must operate with a single motion and must be usable under the conditions of a typical emergency, including low visibility and physical stress. For basement windows specifically, NFPA 101 compliance is particularly important in multi-unit buildings, in states where basement bedrooms are marketed as legal rental units, and in jurisdictions like New York City where Local Law 57 already mandates window guards in residential buildings housing children under 10. Always verify your local jurisdiction’s adopted code edition with your municipal building department before installation.
NYC, Chicago, and LA: Local Ordinances That Go Beyond Federal Standards
While the IBC and IRC set national baseline standards, many major US cities have enacted local ordinances that are stricter. New York City’s Local Law 57 requires window guards on all windows in buildings where a child age 10 or under resides, and this requirement explicitly extends to basement-level windows. Chicago’s building code incorporates specific provisions for egress window sizing in basement-level dwelling units that exceed IRC minimums. Los Angeles County’s Department of Building and Safety has specific inspection protocols for window security hardware in ADUs (Accessory Dwelling Units), which frequently occupy finished basement spaces. If you are a landlord, property manager, or real estate investor operating in any major US metro, verifying local code compliance before installing security window grates for basement windows is essential to avoiding fines, failed inspections, and liability exposure.
How to Choose the Right Security Window Grate for Your Basement
Selecting the correct security window grate for your specific basement situation requires evaluating four key variables: ownership status (own vs. rent), the function of the basement room the window serves, the window’s physical dimensions, and your local building code requirements. Getting all four right ensures you end up with maximum protection, full legal compliance, and a product that installs cleanly without professional contractors or a $600–$1,800 professional installation bill. The following decision framework is designed specifically for American homeowners, renters, landlords, and property managers navigating these choices. For readers already familiar with the broader category of security window guards and related hardware — including security bars for doors and windows and window security grates in general — this section drills down specifically to the basement application where conditions and code requirements differ from above-grade installations. You can explore the full range of window security grates and security window guards to compare all available options before making a final decision.
Renters: Prioritize No-Drill Telescopic Installation
If you rent your home or apartment and the lease prohibits drilling into walls, foundation masonry, or window frames, a telescopic removable security grate is your correct choice. The SWB Model A spans 22 to 36 inches and installs using internal spring tension — no anchors, no epoxy, no damage to the landlord’s property. This matters significantly in cities like San Francisco, Boston, and Seattle, where rental markets are extremely tight and even minor security deposit disputes can be costly. The telescopic design also means you take the security with you when you move — your investment protects your new apartment just as effectively as your current one. For renters concerned specifically about basement windows in urban row houses and garden-level apartments, the Model A delivers the same steel-grade deterrence as a welded permanent grate without any of the installation complications.
Homeowners: Match the Grate to the Room’s Function
Homeowners have the full range of installation options available, but the most important factor is whether the basement room served by the window is used for sleeping. For utility rooms, storage areas, laundry rooms, and mechanical spaces — where no one sleeps — the SWB Model B Wall-Mount bars provide the strongest permanent installation at $91. For finished basement bedrooms, home offices that double as sleeping areas, or basement rental units, the SWB Model A/EXIT at $92 is the only code-compliant choice, delivering the patented quick-release egress mechanism alongside full structural security from the outside. Homeowners in tornado-prone states like Oklahoma, Kansas, and Missouri often use finished basements as primary sleeping and shelter areas — making egress-compliant grates a non-negotiable safety investment in those regions.
Landlords and Property Managers: Think Liability, Not Just Security
For landlords managing multi-unit properties, installing the wrong type of basement window security grate is a liability risk that extends well beyond a burglary claim. If a tenant is injured during a fire because a non-releasable security grate blocked their only egress window, the property owner may face civil liability under state premises liability law, potential criminal negligence charges, and void insurance coverage. The correct approach for any professionally managed property is to install egress-compliant security grates — such as the SWB Model A/EXIT — on all basement windows that serve sleeping areas, and to document the installation with photographs and model specifications for your insurance carrier. The $92 per window investment is negligible compared to the legal exposure of a non-compliant installation.
Installing Security Window Grates on Basement Windows: A Practical Overview
One of the most compelling advantages of SWB security window grates for basement windows is that all three models are designed for DIY installation — no licensed contractor, no locksmith, and no special tools required. The average American homeowner or renter with basic home improvement experience can complete a full basement window grate installation in 15 to 20 minutes per window. This stands in stark contrast to the professional welded security bar installations that remain the historical standard in high-crime neighborhoods — which typically cost between $600 and $1,800 per window according to HomeAdvisor national cost data, require scheduling appointments with licensed contractors, and leave permanent damage to the window frame and surrounding wall. For multi-window basement situations — common in ranch-style homes across the Midwest and South — the DIY cost savings across four to six windows can easily reach $4,000 to $8,000. Full step-by-step instructions are available through the SWB Installation Guide on the company’s official website.
Tools Required and Pre-Installation Measurement
Before ordering any security window grate, measure your basement window’s clear interior width at three points — top, middle, and bottom — since older basement window frames in pre-1980 construction frequently have out-of-square openings. For the SWB Model A Telescopic, your measurement needs to fall within the 22-to-36-inch adjustment range. For the Model B Wall-Mount, measure the masonry or framed wall area surrounding the window to confirm sufficient anchor point clearance. You will need a tape measure, a pencil, and a standard power drill for the Model B wall-mount installation. For the Model A telescopic installation, no drill is required at all. Write down both the interior width and the window height before purchasing to confirm your model selection.
Model A Telescopic Installation Steps
Extend the telescopic bars to approximately the width of your window opening. Insert the unit into the window frame, positioning the end brackets against the interior window stops or frame jambs. Apply tension by compressing or extending the telescopic mechanism per the included hardware guide until the unit is friction-held firmly in place. Test by applying lateral hand pressure to confirm no movement. Total installation time: approximately 15 minutes.
Model B Wall-Mount Installation Steps
Hold the grate frame against the wall at the desired position and mark the anchor hole locations with a pencil. Using a masonry or wood drill bit appropriate to your wall substrate, drill the anchor holes. Insert the provided wall anchors, position the grate frame over the anchors, and secure with the included hardware. Verify the grate sits flush and has no movement. Total installation time: approximately 20 minutes for two people working together on a masonry foundation wall.
Window Well Considerations for Below-Grade Basement Windows
Basement windows that sit in below-grade window wells present an additional installation consideration: the window well’s concrete or corrugated metal surround may reduce the usable mounting area around the window frame. Before purchasing a wall-mount model, measure the clear flat wall area available on all four sides of the window opening from inside the window well. In some older construction — particularly in Northeast states like Pennsylvania, New York, and New Jersey where stone foundation walls are common — the interior window reveal may be very shallow, limiting the available anchor depth. In these cases, the telescopic Model A is often the more practical choice because it mounts entirely within the window’s interior frame without requiring exterior masonry anchoring.
Post-Installation Security Checklist for Basement Windows
After installing security window grates for basement windows, complete a brief post-installation inspection. Test that the grate cannot be pushed inward or pulled outward from the exterior — it should be completely immovable under reasonable hand force. For Model A/EXIT egress units, test the interior quick-release mechanism multiple times to confirm smooth operation; every adult member of the household should practice operating the release so it becomes instinctive in an emergency. Inspect the window’s existing latch and weatherstripping to confirm they remain functional after grate installation. Finally, check that the installed grate does not obstruct any existing window well drainage paths that could cause water accumulation against the foundation — a concern in high-rainfall areas like the Pacific Northwest and Gulf Coast states.
SWB Product Lineup: Which Model Is Right for Your Basement Windows
Security Window Bars offers three distinct models engineered to cover the full spectrum of basement window security needs across American homes. All three models ship via Amazon FBA for fast delivery to all 50 states, making them accessible to homeowners in rural Montana just as readily as to renters in downtown Manhattan. All are constructed from heavy-gauge steel with a matte black powder-coated finish that resists the moisture and humidity common in below-grade basement environments. Here is a detailed breakdown of each model as it applies specifically to basement window installations, so you can make a fully informed purchase decision without needing a security contractor’s consultation.
Model A — Telescopic Window Bars ($90): Best for Renters and No-Drill Installations
The SWB Model A is the top choice for the estimated 44.1 million renters in the United States who cannot or will not drill into their rental property’s walls. Its fully telescopic steel construction adjusts to fit windows between 22 and 36 inches wide — the range that covers the vast majority of standard US basement window sizes. Installation takes 15 to 20 minutes and requires no tools. The matte black finish provides a clean, modern aesthetic that does not look institutional or prison-like — an important consideration for ground-level and basement windows that face neighbors or a street. At $90, the Model A costs less than a single hour of a licensed locksmith’s time in most major US cities. Explore the full specifications for the Model A Telescopic Window Bars on the SWB website.
Model B — Wall-Mount Window Bars ($91): Best for Owned Homes and Utility Basements
The SWB Model B delivers a permanent, anchored security solution for homeowners who want the absolute maximum deterrence on basement windows in non-sleeping areas. Heavy-gauge steel construction and a full perimeter wall-mount frame provide structural resistance that is equivalent in practical stopping power to professionally welded bars — at a fraction of the cost. The powder-coated black finish is specifically formulated to resist the moisture-rich environment of below-grade window wells and unfinished basement wall surfaces. For homeowners in high-crime neighborhoods of cities like Detroit, Baltimore, and Memphis who want a set-it-and-forget-it permanent solution for utility and storage area windows, the Model B at $91 represents an exceptional value. Review the Model B Wall-Mount Window Bars for complete technical specifications.
Model A/EXIT — Egress Compliant Window Bars ($92): The Only Legal Choice for Basement Bedrooms
If any basement window in your home serves a bedroom, guest room, or sleeping area — including finished basement rental units that are increasingly common in high-cost housing markets from Boston to Los Angeles — the SWB Model A/EXIT is the only security window grate that simultaneously protects against intrusion and complies with IBC, NFPA 101, and IRC emergency egress requirements. The patented quick-release mechanism allows any occupant to open the grate from the interior in seconds with a single motion, without tools, without keys, and without any special knowledge of how the system works. From the exterior, the unit presents the same impenetrable steel barrier as a fixed grate. At just $92, it delivers building-code-level protection that professional installation of equivalent egress-compliant hardware would cost $800 to $1,500 or more. See the full egress compliance specifications for the Model A/EXIT Egress Compliant Window Bars.
Security Window Grates vs. Other Basement Window Security Options
Security window grates for basement windows are not the only option on the market, but a clear-eyed comparison against competing approaches consistently demonstrates why hardened steel grates provide the best combination of deterrence strength, installation simplicity, code compliance, and cost-effectiveness for the American market. Alternatives including window films, window alarms, and polycarbonate security inserts each occupy a niche role, but none of them stop a determined intruder from physically entering through a basement window the way a steel grate does. Understanding the limitations of each alternative helps homeowners make security decisions grounded in realistic threat assessment rather than marketing claims. For a comprehensive look at how security window grates fit within the broader ecosystem of security window guards, security bars for windows and doors, and window security grates for all window types, the SWB product library covers every application in detail.
Window Security Film: Useful Supplement, Not a Standalone Solution
Security window films — polyester laminate sheets applied to the interior glass surface — can slow glass breakage and prevent easy glass removal from the frame. However, they do nothing to prevent an intruder from breaking the glass entirely and stepping through the opening once the glass is sufficiently weakened. For a basement window where noise is already muffled by below-grade location, a determined burglar can break through filmed glass in 30 to 45 seconds with a center punch. Window film is a useful supplementary layer alongside a steel security grate, but it is never an adequate standalone solution for a high-risk basement window application.
Window Alarm Sensors: Detection Without Prevention
Magnetic contact sensors and glass-break acoustic sensors are standard components of most residential alarm systems. They detect intrusion — but only after the break-in has already begun. In the 60 to 90 seconds it takes for a monitored alarm to generate a police dispatch, an experienced burglar can be inside your home and already moving toward valuables. In cities where police response time to residential alarm calls averages 7 to 11 minutes — a documented reality in under-resourced departments serving large cities like Chicago and Los Angeles — the alarm only informs you that a crime has already occurred. Steel security window grates prevent the entry from happening in the first place. The National Crime Prevention Council explicitly recommends physical barrier hardening as the primary deterrence strategy, with detection technology as a secondary layer.
Polycarbonate Window Inserts and Lexan Panels: Expensive and Limited
Polycarbonate security inserts are rigid plastic panels that fit into window frames to resist impact. While high-grade polycarbonate (Lexan) is genuinely impact-resistant, quality security-rated panels cost $200 to $500 per window before installation labor, and they reduce natural light and ventilation in an environment — the basement — where both are already limited. They also provide zero deterrence visibility from the exterior; a burglar cannot tell whether a basement window has a polycarbonate insert or standard glass without touching it. By contrast, a visibly installed steel security grate communicates deterrence immediately and unambiguously from the street or exterior access point, often preventing any approach at all.

Security window grates are not universally required by law across the USA, but specific rules apply in certain situations. If a basement window serves as the designated emergency egress opening for a sleeping room, IBC Section 1030 and NFPA 101 require that any grate or bar installed over it must be releasable from the interior without tools or keys. Some cities, including New York City under Local Law 57, require window guards in residential units where children under 10 years old reside. Always check your local municipal building code before installation to confirm compliance requirements in your jurisdiction.
Yes. The SWB Model A Telescopic Window Bars are specifically designed for no-drill installation. The telescopic steel bars use internal spring tension and adjustable end brackets to hold securely within the window frame opening without requiring any anchors, screws, or penetrations into the surrounding wall or masonry. This makes the Model A the ideal solution for renters, tenants in lease-restricted properties, or any homeowner who wants to avoid damaging foundation walls. Installation takes approximately 15 to 20 minutes and requires only a tape measure for pre-installation sizing.
The terms are often used interchangeably in the US market, but there is a subtle distinction in common usage. A security window grate typically refers to a rigid steel grid or bar assembly that covers the entire window opening and is intended primarily for anti-intrusion protection. A security window guard may refer to a similar product with an additional emphasis on child fall prevention — a category governed by New York City’s Local Law 57 and similar child safety ordinances in other states. In practice, SWB’s product line serves both purposes: the steel construction stops intruders while the fixed installation prevents accidental falls from ground-floor and basement windows alike.
No — properly designed security window grates for basement windows use an open-bar or open-grid construction that allows natural light, airflow, and ventilation to pass through freely. The steel bars occupy a fraction of the total window opening area, leaving the vast majority of the opening unobstructed. You can open the window normally behind the grate to ventilate the basement. This is a significant advantage over polycarbonate insert panels, which can block light transmission by 30% to 50% and eliminate ventilation entirely when installed. SWB models are designed specifically to maintain full window functionality while adding steel-grade security.
The SWB Model A/EXIT features a patented quick-release mechanism mounted on the interior face of the grate assembly. In an emergency, an occupant pushes or turns the release lever — a single-motion operation — which disengages the locking mechanism and allows the entire grate to swing open or be pushed out of the window opening. The release requires no key, no tool, and no prior knowledge of the product; it operates intuitively under stress, low visibility, and smoke conditions. From the exterior, the release mechanism is not accessible, meaning the quick-release function provides no advantage to a would-be intruder trying to enter from outside.
The SWB Model A Telescopic and Model A/EXIT Egress Compliant bars are adjustable to fit windows from 22 inches to 36 inches in interior width. This range covers the vast majority of standard US residential basement window sizes, including the common 32-inch and 36-inch hopper and awning window configurations used in homes built after 1970. For larger or unusually sized basement windows — which occasionally appear in older pre-war construction in cities like Chicago, Philadelphia, and Boston — the Model B Wall-Mount can be configured to cover wider openings. Check your window’s interior width measurement before ordering to confirm the correct model selection.
According to HomeAdvisor national cost data, professional installation of welded or permanently mounted security bars on a residential window typically costs between $600 and $1,800 per window, depending on the market, the contractor, and the complexity of the installation. For a home with four basement windows, professional installation can easily reach $4,000 or more. By contrast, SWB security window grates start at $90 per window and install in 15 to 20 minutes without any professional labor cost. For most American homeowners and renters, the DIY SWB solution delivers equivalent structural protection at less than 10% of the cost of a professional installation.
Many US homeowner’s insurance carriers offer discounts for documented physical security upgrades, including window security bars and grates. The specific discount amount and eligibility criteria vary by insurer, policy type, and state. According to the Insurance Information Institute, homes with verified physical security hardening measures — including window bars, reinforced doors, and deadbolts — may qualify for property crime risk discounts of 5% to 20% on the home’s contents and structure coverage. Contact your insurance agent with the SWB model specifications and installation documentation to inquire about applicable discounts in your policy. Keep your Amazon order confirmation and installation photos as documentation.
