Window Bars for Basement Windows: Home Security Guide for US Homeowners
Discover why window bars for basement windows are essential for home security. Learn types, egress codes, installation tips, and top picks for US homeowners.
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 have a basement, you have a vulnerability — and statistically, it is one of the most dangerous vulnerabilities in any American home. According to FBI Uniform Crime Reports, approximately 6.7 million residential burglaries occur in the United States every year, and law enforcement experts consistently identify ground-floor and below-grade openings as primary entry points. Window bars for basement windows home security are not optional in high-risk environments — they are the single most effective physical deterrent you can install. Basement windows are narrow, often partially concealed by landscaping or window wells, and are frequently overlooked during security audits. Whether you live in a ground-floor apartment in Chicago, a townhouse in Philadelphia, or a single-family home in Atlanta, this guide covers everything you need to know: why basement windows are targeted, which bar types work best for below-grade openings, egress code requirements, proper measurement techniques, and step-by-step installation advice.

Why Basement Windows Are the #1 Burglary Entry Point in US Homes
Most homeowners invest in front-door locks, alarm systems, and motion-sensor lights — and then completely ignore the basement. That oversight costs American families billions of dollars annually. According to the U.S. Department of Justice, first-floor windows account for approximately 23% of all home break-in entry points, and basement windows — a subcategory of that statistic — are disproportionately represented because they offer burglars something the front door never can: concealment. A basement window tucked below ground level in a window well, hidden behind shrubs, or facing an alley gives an intruder cover time. The average forced entry through a basement window takes under 60 seconds. Compare that to a reinforced door with a deadbolt, which can take several minutes to defeat, and it becomes clear why professional burglars systematically target below-grade openings first. Cities like Detroit, Memphis, Baltimore, and Houston — all ranking consistently in the FBI’s top-20 high-crime metro areas — see disproportionate rates of basement-entry burglaries in neighborhoods with aging housing stock where basement windows are large, single-pane, and completely unprotected. Installing window bars for basement windows home security is the direct, structural answer to this specific threat. No alarm system can prevent entry — it can only notify. Steel bars physically stop intrusion before it begins.
The Concealment Factor: What Makes Basement Windows So Attractive to Burglars
Professional burglars — not opportunistic amateurs — select entry points based on three criteria: speed of entry, concealment during entry, and low likelihood of detection. Basement windows satisfy all three simultaneously. A window well creates a natural alcove that hides a crouching intruder from street view. Basement glass is frequently older, thinner, and easier to break quietly than modern double-pane windows. And because most homeowners place their security investment at eye level — cameras pointed outward, motion lights facing the driveway — the basement blind spot goes entirely unmonitored. According to research from the University of North Carolina’s Department of Criminal Justice, 83% of convicted burglars reported that visible security measures directly changed their target selection. Steel window bars for basement windows are one of the most visible deterrents possible — they signal to any would-be intruder that forced entry will be time-consuming, noisy, and ultimately futile.
High-Risk Home Types That Need Basement Window Bars Most Urgently
Not every home carries equal risk, and understanding your property type helps prioritize your security investment. Older single-family homes built before 1980 in cities like Cleveland, Pittsburgh, St. Louis, and Cincinnati typically feature large basement windows designed for ventilation — not security. These windows are wide, often at or near ground level, and made with outdated glazing. Garden-level apartments in cities like New York, Boston, and Washington D.C. face unique risks because their basement windows are sometimes large enough for an adult to climb through without any gymnastics. Split-level homes in suburban Chicago or suburban Dallas often have basement windows that open directly onto backyard areas with minimal neighbor visibility. In every one of these scenarios, window bars for basement windows home security provide the same outcome: a physical steel barrier that makes forced entry structurally impossible without tools that would create noise and take time — the two things every burglar is trying to avoid.
Types of Window Bars That Work Best for Basement Windows
Not all window security bars are created equal, and basement windows present specific installation challenges that require purpose-fit solutions. The geometry of a basement window — narrow, often set into a masonry or concrete frame, sometimes partially below grade inside a window well — demands bars that are structurally robust, corrosion-resistant, and sized to fit non-standard openings. Understanding the three primary categories of window bars available for basement applications helps you make the right choice the first time. The wrong bar system — one that’s too wide, too lightweight, or installed into crumbling mortar — provides a false sense of security. The right system, properly installed, makes your basement windows physically impenetrable. At Security Window Bars, our product lineup was engineered specifically with this variety of installation environments in mind, from finished basement walls in suburban Ohio to concrete-surround openings in Chicago bungalows.
Telescopic Steel Bars: The Best Option for Renters and Adjustable Openings
The SWB Model A — Telescopic Window Bars are the most versatile solution for basement windows that fall within the 22″ to 36″ width range, which covers the majority of standard US basement window sizes. The telescopic design means the bar expands to fit precisely within the window frame without drilling into concrete or masonry — a critical advantage in basement environments where drilling into concrete requires specialized tools and risks cracking the frame. Installation takes 15 to 20 minutes. The matte black powder-coat finish resists moisture — important in below-grade environments where condensation is common. For renters in garden-level apartments in NYC or Boston who cannot make permanent modifications to their unit, telescopic bars are the only code-acceptable, damage-free solution available. You can learn more about the full specifications of our telescopic system at the official Model A product page at https://securitywb.com/model-a/, where sizing charts for common US basement window dimensions are available.
Wall-Mount Fixed Bars: Maximum Security for Owned Homes and Ground-Floor Openings
For homeowners who own their property and want the absolute maximum level of security for their basement windows, the SWB Model B — Wall-Mount Window Bars offer permanent, heavy-gauge steel installation that is structurally equivalent to professionally welded bar systems costing $600 to $1,800 per window. The Model B is mounted directly into the surrounding masonry, concrete, or wood framing using heavy-duty anchors, creating a fixed barrier that cannot be pushed, pulled, or pried from outside the window. This is the recommended configuration for ground-floor windows facing alleys, rear yards, or any area with reduced natural surveillance. Homeowners in high-crime neighborhoods of Houston, Memphis, or Baltimore consistently choose fixed wall-mount systems for basements because the deterrent value is immediately visible to anyone approaching the window. The powder-coated black finish is weatherproof and corrosion-resistant, handling the humidity fluctuations common in below-grade environments without rusting or weakening over time. Details on the Model B are available at https://securitywb.com/model-b/.
Egress-Compliant Bars: The Code-Required Solution for Finished Basement Bedrooms
If your basement contains a bedroom, a sleeping area, or any room classified as a habitable space under your local building code, standard fixed bars may not be legally permissible without a quick-release mechanism. The International Residential Code (IRC) Section R310 requires emergency escape and rescue openings — commonly called egress windows — in every sleeping room, including those in finished basements. Installing bars that permanently block an egress window without a code-approved quick-release system creates a life-safety violation and potential liability. The SWB Model A/EXIT — Egress Compliant Window Bars solve this problem with a patented quick-release mechanism that allows occupants to open the bars from the inside within seconds during a fire or emergency, while providing the same steel security barrier against outside forced entry. The Model A/EXIT meets IBC, NFPA 101, and OSHA standards. Full compliance information is available at https://securitywb.com/model-a-exit/.
Understanding Egress Code Requirements for Basement Window Bars
Building code compliance is not optional — and in the context of basement window bars, the stakes are life-and-death serious. The International Building Code (IBC) and the International Residential Code (IRC), adopted in some form by all 50 US states, establish minimum requirements for emergency egress from sleeping areas. The National Fire Protection Association’s NFPA 101 Life Safety Code adds further requirements applicable to multi-family residential buildings and commercial properties. Understanding where these codes apply, what they require, and how they interact with your window bar selection is essential before you install any bar system on a basement window in a finished space. Failing to comply does not just risk a fine — it can mean the difference between your family escaping a house fire and being trapped. This is why SWB engineered the Model A/EXIT specifically for these environments: security without compromising the life-safety escape route that every sleeping area legally requires.
IRC Section R310: What the Emergency Egress Rule Means for Your Basement
IRC Section R310.1 requires that every sleeping room have at least one operable emergency escape and rescue opening. For basement bedrooms and habitable basement rooms used for sleeping, this opening must meet the following minimum dimensions: a minimum net clear opening of 5.7 square feet (or 5.0 square feet at grade level), a minimum clear opening height of 24 inches, a minimum clear opening width of 20 inches, and a maximum sill height of 44 inches above the finished floor. Any window bar or security grille installed over this opening must be openable from the inside without the use of a key, tool, or special knowledge. The SWB Model A/EXIT meets all of these requirements through its patented quick-release system, which disengages the bar entirely from the inside with a single-motion lever — no key, no tools, no complicated mechanism under pressure. If you are finishing your basement and adding a bedroom, this code requirement is non-negotiable in every jurisdiction that has adopted the IRC, which includes the vast majority of US counties and municipalities.
NYC Local Law Considerations and Multi-Family Basement Window Regulations
New York City operates under its own building code framework, but the principles align with IRC egress requirements. NYC Local Law 57 — which mandates window guards in buildings with children under 10 — applies to windows above certain heights but also creates a framework of responsibility for landlords citywide. In garden-level and basement apartments in Brooklyn, the Bronx, Queens, and Upper Manhattan, window bars that block egress without a quick-release mechanism violate both NYC Building Code and FDNY fire-safety regulations. Landlords who install non-compliant bars face fines and, in the event of a fire fatality, significant civil liability. The solution in every case is an egress-compliant bar system — one that provides the security tenants need without eliminating the emergency escape route the law mandates. Similar considerations apply in Chicago (under Illinois Building Code), Los Angeles (under California Building Code Title 24), and Seattle (under the Washington State Building Code).
How to Measure Basement Windows for Security Bar Installation
Accurate measurement is the foundation of a successful basement window bar installation. Basement windows present unique measurement challenges compared to standard above-grade windows: frames may be set into concrete or masonry rather than wood, window well surrounds may limit external access, and years of moisture exposure may have caused frames to warp or become irregular. Taking three separate measurements — top, middle, and bottom of the window width — and using the smallest measurement ensures the bars fit snugly without gaps that could be exploited. Height measurement matters equally, particularly when spacing multiple horizontal bars across a taller basement opening. At SWB, we recommend measuring inside the window frame (not the rough opening) for telescopic bar installations, and measuring the surrounding wall surface for wall-mount installations. Having the correct measurements before ordering eliminates the most common installation problem: bars that are slightly too wide or too narrow for the specific opening.
Step-by-Step Measurement Process for Standard Basement Window Widths
Begin by measuring the inside width of your basement window frame at three points: the top of the opening, the center, and the bottom. Record all three measurements and use the smallest number as your working width. For most American basement windows built to standard framing dimensions, you will find widths clustering around 24 inches, 28 inches, 30 inches, or 36 inches — all within the 22-to-36-inch range covered by SWB telescopic bars. Next, measure the clear height of the opening to determine how many horizontal bars you will need for adequate coverage. A standard rule of thumb is one bar for every 5 to 6 inches of height, with bars placed at equal intervals. For basement windows in window wells, also measure the depth of the well and the distance from the window frame to the outer edge of the well, since this affects whether you will install the bars flush with the interior frame or recessed into the well exterior. Our full installation guide at https://securitywb.com/installation/ includes printable measurement worksheets for all three SWB models.
Dealing with Non-Standard Basement Window Shapes and Concrete Surrounds
Older homes — particularly those built before 1960 in cities like Detroit, Cleveland, Pittsburgh, and Chicago — often feature basement windows with concrete or stone surrounds that are irregular, slightly out of square, or wider at the top than at the bottom due to decades of settling. For these openings, telescopic bars remain viable as long as the narrowest width falls within the product’s adjustment range. For openings that are significantly out of square, wall-mount bars (Model B) may be preferable because they attach to the surrounding wall surface rather than spanning the frame itself, allowing for a more forgiving fit. In extreme cases — very wide basement windows exceeding 36 inches, or multi-pane configurations common in older bungalows — two sets of bars installed side by side create full coverage. If you have a non-standard configuration and are unsure of the right approach, our team at https://securitywb.com/contact/ can provide personalized guidance based on your specific window dimensions and installation environment.
DIY Installation of Window Bars on Basement Windows: A Practical Guide
One of the most persistent myths in home security is that professional-grade window bar installation requires a locksmith or a licensed contractor. For SWB telescopic systems, that is simply not true. The Model A installs in 15 to 20 minutes using tools most American homeowners already own — a measuring tape, a pencil, and a level. No concrete drilling, no masonry anchors, no specialized power tools. For renters in below-grade apartments in New York City, Los Angeles, or Chicago who have never touched a power drill, this changes the security equation entirely. Even the wall-mount Model B, which does require drilling, is designed for straightforward installation using standard masonry drill bits and expansion anchors included with the product. The key to a successful DIY basement window bar installation is preparation: having accurate measurements before you begin, having all tools and hardware staged near the window, and following the installation sequence in the correct order. Rushing the process or skipping the leveling step are the two most common DIY installation errors.
Installing Telescopic Bars on Basement Windows Without Drilling
The no-drill installation process for SWB Model A telescopic bars follows a simple sequence. First, extend the telescopic bar to approximately 1 inch less than your measured window width. Position the bar horizontally inside the window frame at your desired height — for most basement windows, the first bar placement should be approximately 6 inches from the top of the frame. Apply even outward pressure on both ends of the telescopic bar simultaneously until the rubberized end caps make firm contact with both sides of the window frame. The internal spring-tension mechanism locks the bar in place. Test by applying firm lateral and forward pressure to confirm the bar does not shift or disengage. Repeat for additional bars at measured intervals down the height of the opening. The entire process for a standard 30-inch basement window with three horizontal bars takes approximately 20 minutes from opening the package to confirming security. No hardware, no mess, no damage to the window frame — and the bars come out just as easily when you move.
Installing Wall-Mount Bars on Masonry Basement Frames
Wall-mount installation (Model B) begins with marking anchor point locations on the masonry or concrete surrounding your basement window. Use a level to ensure mounting brackets are perfectly horizontal — a bar that’s even slightly off-level creates visible torque that can loosen anchors over time. Use a hammer drill with a carbide-tipped masonry bit sized to match your expansion anchor diameter. Drill anchor holes to the depth specified in the Model B installation guide at https://securitywb.com/installation/. Insert expansion anchors, tap flush with the wall surface, and attach mounting brackets using the provided hardware. Secure the bar assembly to the brackets and test by applying firm outward pressure in multiple directions. For basement windows in concrete block or poured concrete walls — common in homes across the Midwest and Southeast — use anchor bolts rated for concrete, not standard drywall anchors. The strength of a wall-mount installation is entirely dependent on anchor quality and proper depth. When done correctly, a wall-mounted SWB bar can withstand hundreds of pounds of force — far exceeding what any burglar can apply manually.
Common Installation Mistakes to Avoid in Below-Grade Environments
Basement environments introduce specific challenges that can compromise an otherwise correct installation. The most frequent mistake is underestimating moisture impact on installation hardware. Standard zinc-plated screws will corrode in below-grade environments where humidity is consistently high — always use stainless steel or hot-dip galvanized hardware for any basement bar installation. The second most common mistake is over-relying on old window frame wood as an anchor point. Basement window frames in homes built before 1970 may have rotted sill plates that appear solid but crumble under pressure — test the frame integrity before installing any tension-based bar. The third mistake is spacing bars too far apart. For basement windows, a maximum 5-inch clear space between bars prevents an intruder from reaching through to manipulate locks or latches. Our installation guide at https://securitywb.com/installation/ includes a spacing chart for all standard US basement window heights.
Comparing Window Bar Options: Steel Window Security Bars vs. Other Basement Security Solutions
The home security market is filled with products claiming to protect basement windows — security film, glass break sensors, window wedges, door and window alarms, motion-sensor lights, and various types of home window bars and window security sticks. Each of these products has merit in a layered security strategy, but none of them — individually or collectively — provides the physical barrier that steel window bars deliver. Understanding why physical security at the structural level outperforms technology-dependent solutions is central to making a well-informed decision about your basement. Products like steel window security bars, home window bars, and commercial-grade grate door systems all share one characteristic: they make physical intrusion structurally impossible without heavy-duty tools. Electronic systems detect intrusion after it begins. Steel bars prevent it from beginning at all. For a comprehensive approach to full-perimeter security that includes not just window bars but also related solutions like window stop bars, window security sticks, and exterior bar systems, exploring the full range of options — from home window bars to commercial door security bars and grate door configurations — provides a complete framework for residential perimeter hardening.
Why Window Security Film and Sensors Are Not Enough for Basement Protection
Window security film strengthens glass against breakage — it slows intrusion by a few additional seconds but does not stop a determined burglar with a glass cutter or a breaker bar. A glass break sensor detects the sound of breaking glass and triggers an alarm — but by the time the alarm sounds, the window is already compromised and entry is already in progress. Motion-sensor lights are excellent deterrents in areas with natural surveillance (neighbors who can see and respond) but are largely irrelevant in window wells that are below grade and face alley spaces. Window wedges and window security sticks prevent windows from opening but can be defeated by breaking the glass itself. Steel window bars for basement windows home security are the only solution that addresses the structural reality of forced entry: they make the opening itself impassable regardless of what happens to the glass, the frame, or the locking mechanism. They are the last line of physical defense — and the most important one.
Cost Comparison: DIY Steel Bars vs. Professional Welded Bar Installation
Professional window bar installation — the kind performed by a licensed locksmith or security contractor using welded iron bars — costs between $600 and $1,800 per window in most major US cities, according to HomeAdvisor national averages. For a typical home with four basement windows, that represents a potential investment of $2,400 to $7,200. SWB telescopic bars start at $90 per window and wall-mount systems at $91 per window — and both are DIY-installed in under 30 minutes with no professional labor cost. The steel construction is equivalent in strength to welded bar systems. The telescopic and adjustable designs are actually superior in flexibility. And for renters, the DIY removable option is the only viable choice — no landlord will authorize a $600 welded bar installation that cannot be reversed. Available on Amazon USA for fast delivery to all 50 states, SWB bars make professional-grade basement security accessible at a fraction of the traditional cost.
Child Safety and Fall Prevention: An Additional Reason to Install Basement Window Bars
While the primary focus of this guide is burglary prevention, window bars for basement windows serve a second critical safety function that is especially important for families with young children: fall prevention. Basement windows that open onto window wells can present a fall hazard for toddlers and young children who climb near or onto window sills. Window wells with significant depth — required in many jurisdictions for egress compliance — create a fall zone that can result in serious injury. The U.S. Consumer Product Safety Commission documents hundreds of child window fall injuries annually, with a significant percentage involving below-grade window openings. Horizontal steel bars installed across basement window openings prevent children from climbing through or falling out of these openings while still allowing ventilation when windows are open. This dual function — security from outside intrusion and safety from inside falls — makes basement window bars an even more critical investment for families with children. New York City’s Local Law 57, which mandates window guards in apartments where children under 10 reside, specifically recognizes this dual-purpose safety value.
Spacing Requirements for Child Safety vs. Burglar Deterrence
The spacing between horizontal bars matters differently depending on whether your primary concern is child fall prevention or burglary deterrence. For child safety, the New York City Housing Maintenance Code and guidelines from the American Academy of Pediatrics recommend maximum openings of no more than 4 inches between bars — preventing children from fitting their heads through the opening. For burglary deterrence alone, a maximum of 5 inches between bars is the commonly cited standard, preventing an arm from reaching through comfortably to manipulate latches. When both concerns are present — as they are in most family homes — using the stricter 4-inch spacing standard addresses both simultaneously. Calculate your bar quantity accordingly: for a 24-inch-tall basement window, a 4-inch maximum spacing requires approximately five horizontal bars, with the first and last bar positioned within 2 inches of the frame edges.
Ventilation Considerations When Installing Bars on Basement Windows
A common concern homeowners raise about basement window bars is ventilation — specifically, whether bars interfere with the window’s ability to provide airflow for radon mitigation, humidity control, or basic air circulation. The straightforward answer is no: horizontal steel bars do not obstruct airflow in any meaningful way. Bars are solid steel rods, not panels — air passes freely between them in all directions. In fact, bars allow windows to remain open for ventilation without creating a security gap, because the bars prevent entry regardless of whether the window sash itself is open or closed. This is particularly valuable in humid climates like the Gulf Coast, the Mid-Atlantic, and the Southeast, where basement humidity control through natural ventilation is important for preventing mold. You can leave your Houston or Atlanta basement windows open for airflow all summer without sacrificing security — a benefit that no alarm system or film product can offer.
Choosing the Right SWB Bar for Your Basement Window: A Decision Guide
With three distinct SWB models available — each designed for specific installation scenarios — choosing the right bar for your basement window comes down to four factors: ownership status (renter vs. homeowner), basement use (unfinished storage vs. finished bedroom), window width (standard vs. non-standard), and local code requirements. Working through these four factors systematically leads every homeowner or renter to a clear recommendation without ambiguity. Security Window Bars was designed with this diversity of American housing in mind — from garden-level studios in Brooklyn to finished walk-out basements in suburban Dallas. There is no single universal basement window security solution, but there is always a right SWB model for your specific situation. The decision framework below eliminates guesswork and ensures you select the bar that will perform correctly, comply with applicable codes, and protect your home or rental unit effectively from day one.
Decision Matrix: Which SWB Model Is Right for Your Basement Window?
Use this decision framework to identify your best option. If you are a renter who cannot modify the property, the SWB Model A Telescopic is your answer — no drilling, no damage, full security. If you own your home and your basement windows are in unfinished utility or storage spaces (not sleeping areas), the SWB Model B Wall-Mount provides maximum permanent security at $91 per window. If your basement contains a bedroom, guest room, or any space used for sleeping — regardless of whether you rent or own — the SWB Model A/EXIT Egress Compliant bar is the only code-legal option for bars over those windows. It provides identical security to the standard telescopic model with the addition of the patented quick-release mechanism required by IRC Section R310. If you are unsure which category applies to your space, consult your local building department or contact SWB directly at https://securitywb.com/contact/ for personalized guidance based on your city, state, and window configuration.

Yes, window bars are legal across the United States, but they are subject to building code requirements in certain contexts. The most important requirement is that any window bar installed over a window in a sleeping room — including finished basement bedrooms — must have a quick-release mechanism that allows occupants to exit from the inside without a key or tool. This requirement comes from IRC Section R310 and NFPA 101. Non-sleeping basement spaces such as utility rooms, storage areas, and unfinished areas do not require egress-compliant bars. Always check your local jurisdiction’s adoption of the IRC or IBC, as some municipalities have additional requirements.
Yes — the SWB Model A Telescopic Window Bars are specifically designed for no-drill installation. The telescopic bar expands to fit inside the window frame using internal spring tension and rubberized end caps that grip the frame securely without any drilling, screws, or hardware. This makes them ideal for renters, for basement windows set in masonry surrounds where concrete drilling is difficult, and for anyone who wants a removable security solution. The no-drill design works effectively on basement windows between 22 and 36 inches wide, which covers the majority of standard US basement window sizes.
Yes. Under IRC Section R310, every sleeping room — including basement bedrooms in finished basement spaces — must have at least one emergency escape and rescue opening that can be operated from the inside without keys or tools. If you install standard fixed bars over a basement bedroom window, you are creating a building code violation and a potential life-safety hazard. The SWB Model A/EXIT Egress Compliant Window Bars are specifically engineered for this application: they provide the same steel security barrier as standard bars but include a patented quick-release mechanism that disengages the bar from the inside in one motion, meeting IBC, NFPA 101, and OSHA standards.
The number of horizontal bars needed depends on the height of your basement window and the spacing you choose. For maximum security and child safety compliance, bars should be spaced no more than 4 to 5 inches apart. For a standard basement window that is 16 inches tall, three to four horizontal bars provide adequate coverage. For a taller opening of 24 inches — common in below-grade windows designed for egress — five bars at 4-inch spacing provide complete protection. Our installation guide at https://securitywb.com/installation/ includes a spacing chart based on window height so you can calculate the exact quantity for your specific opening.
No — steel window bars do not meaningfully obstruct airflow. The bars are solid steel rods with open space between them in all directions, allowing air to pass freely. In fact, bars enable you to keep basement windows open for ventilation without creating a security vulnerability, because the bars prevent entry regardless of the window sash position. This is especially valuable in high-humidity climates across the Gulf Coast, Southeast, and Mid-Atlantic where basement ventilation is important for controlling moisture and preventing mold. You can run your basement fan with the window open all summer and maintain full security.
SWB basement window bars start at $90 for the Model A Telescopic, $91 for the Model B Wall-Mount, and $92 for the Model A/EXIT Egress Compliant system — all available on Amazon USA with fast delivery. Professional window bar installation by a licensed locksmith or security contractor typically costs $600 to $1,800 per window in major US cities, according to HomeAdvisor national cost data. For a home with four basement windows, professional installation can cost $2,400 to $7,200. DIY installation of SWB bars covers those same four windows for $360 to $368 — with no labor cost, no scheduling delay, and no permanent structural modification required.
Yes — steel window bars are widely recognized by law enforcement as the most effective physical deterrent for window-based forced entry. According to research from the University of North Carolina’s Department of Criminal Justice, 83% of convicted burglars stated that visible security measures changed their target selection. Physical steel bars make forced entry through a basement window structurally impossible without heavy-duty tools that create significant noise and require extended time — exactly the conditions burglars avoid. Unlike alarms (which detect intrusion after it begins) or cameras (which record but do not prevent), steel bars stop the intrusion physically before it can occur.
Yes, and in some jurisdictions landlords are required to provide window security measures. Landlords installing bars on basement apartment windows must ensure compliance with local building codes — specifically egress requirements for any window in a sleeping area. The SWB Model A/EXIT is the recommended solution for rental properties because it provides full security while meeting fire-egress code requirements in all jurisdictions that have adopted the IRC. Telescopic models are also popular with landlords because they can be easily removed and reinstalled between tenant occupancies without leaving permanent damage to window frames, protecting the property’s condition and the landlord’s maintenance costs.
