How Long Does It Take to Install Window Security Bars?
A single window security bar takes approximately 15 minutes to install using the frame-mount method and 30-45 minutes using the masonry-mount method. For a typical home with 6-10 windows, the entire project takes one afternoon for DIY frame-mount installations or one full day for masonry-mount work. These timeframes assume you have already measured your windows, purchased the correct bars, and have the necessary tools ready. The actual installation — drilling pilot holes, positioning the bar, and driving the fasteners — is the fast part. Preparation is what takes time.
This post breaks down the installation timeline for every common scenario so you can plan your project accurately and know exactly what to expect.
Quick Answer: Installation Time by Mount Type
| Mount Type | Time Per Window | Tools Needed | Skill Level |
|---|---|---|---|
| Frame mount (SWB Model A) | 15-20 minutes | Drill, level, tape measure | Beginner |
| Masonry mount (SWB Model B) | 30-45 minutes | Rotary hammer drill, level, wrench | Intermediate |
| Egress/quick-release (Model A/EXIT) | 15-25 minutes | Same as frame mount + test release | Beginner |
| Modular stack (wide opening) | 25-35 minutes per module | Same as frame mount | Beginner-Intermediate |
Frame-Mount Installation: 15 Minutes Per Window
Frame-mount installation is the fastest and most accessible method. The SWB Model A attaches directly to the window frame — wood, vinyl, or aluminum — using structural lag screws or anti-tamper security fasteners. No cutting, welding, or specialty equipment is required.
Time Breakdown
- Extend and lock the telescopic bar to your measured window width — 1 minute
- Position the bar in the window opening and check level — 2 minutes
- Mark pilot hole locations through the bracket holes — 1 minute
- Pre-drill pilot holes into the frame (4-8 holes depending on bracket design) — 3 minutes
- Reposition the bar and align with pilot holes — 1 minute
- Drive anti-tamper fasteners through brackets into frame — 5 minutes
- Test for rigidity — push, pull, and wiggle to verify solid mount — 1 minute
- Clean up — 1 minute
Total: approximately 15 minutes per window. First-time installers may take 20-25 minutes on the first window as they learn the process, then speed up to 12-15 minutes on subsequent windows. For detailed instructions, see our complete DIY installation guide.
Masonry-Mount Installation: 30-45 Minutes Per Window
Masonry-mount installation with the SWB Model B takes longer because drilling into brick, concrete, or block requires a rotary hammer drill and the anchor-setting process has more steps. The additional time is in the drilling — masonry drilling is slower than wood drilling.
Time Breakdown
- Position and mark — 3 minutes
- Drill anchor holes with rotary hammer (4-8 holes into brick or concrete) — 10-15 minutes
- Clean holes with wire brush and compressed air — 2 minutes
- Set expansion anchors — 5 minutes
- Position bar and align — 2 minutes
- Tighten anchor bolts — 5 minutes
- Test rigidity and adjust — 3 minutes
Total: approximately 30-45 minutes per window. Concrete block walls drill faster than solid concrete; brick falls in between. The quality of your rotary hammer drill also affects speed — a professional-grade SDS drill cuts through masonry significantly faster than a budget hammer drill.
Whole-House Project Timelines
Here is what to expect for common whole-house installations, including preparation time.
| Scenario | Windows | Mount Type | Install Time | Total Project (with prep) |
|---|---|---|---|---|
| Apartment (ground floor) | 4-5 | Frame | 1-1.5 hours | 2-3 hours |
| 3BR house (ground floor only) | 6-8 | Frame | 1.5-2.5 hours | 3-4 hours |
| 3BR house (all floors + sliding door) | 10-14 | Frame | 2.5-4 hours | 4-6 hours (one day) |
| Brick duplex (2 units) | 12-16 | Masonry | 6-10 hours | 1.5-2 days |
| Retail storefront | 4-8 | Frame or masonry | 1-4 hours | Half day to full day |
"Total project" includes preparation time: measuring windows, unboxing and organizing bars, gathering tools, adjusting telescopic bars to width, and cleanup. The actual drilling and fastening is typically only 40-60% of the total project time. For measurement instructions, see our window measurement guide.
Factors That Add Time
First-Time Installation
Your first window takes the longest as you learn the product and the process. Expect 25-30 minutes for the first frame-mount window, dropping to 12-15 minutes by the third or fourth window. This learning curve is completely normal.
Older Homes with Non-Standard Windows
Windows in homes built before the 1970s are often non-standard sizes, out of square, or have deteriorated frames. Telescopic bars like the Model A compensate for size variation, but severely out-of-square windows may require shimming or repositioning that adds 5-10 minutes per window.
Hard Masonry
Poured concrete takes the longest to drill through — 2-3 times longer than brick. If your building has concrete walls, budget 45-60 minutes per window for masonry-mount installation.
Elevated Windows
Working from a ladder adds setup time, repositioning time, and the general slowdown of working at height. Budget an extra 10-15 minutes per window for ladder work.
Modular Installations
Wide openings like sliding glass doors require 2-3 Model A units stacked modularly. Each module takes its own 15-minute installation, plus 5-10 minutes to align and connect the modules to each other for seamless coverage.
DIY vs. Professional: Time Comparison
| Factor | DIY | Professional |
|---|---|---|
| Time per window (frame mount) | 15-25 minutes | 8-12 minutes |
| Time per window (masonry) | 30-60 minutes | 20-30 minutes |
| 8-window home (frame) | 3-4 hours | 1.5-2 hours |
| Cost | $0 (your time) | $50-$100 per window |
| Learning curve | Yes (first 1-2 windows) | None |
Our recommendation: DIY frame-mount installation is straightforward for anyone comfortable with a cordless drill. You will save $400-$800 on a typical home project and finish in a single afternoon. Masonry-mount installation is worth hiring a professional if you do not already own a rotary hammer drill — the tool alone costs $150-$300, which is close to the labor cost for a contractor to do the job.

Frequently Asked Questions
Can one person install window security bars alone?
Yes, a single person can install most standard-width window bars alone. The SWB Model A weighs approximately 10-15 pounds, which is manageable for one person to hold in position while driving fasteners. For wide modular setups, bars above the first floor, or particularly heavy masonry-mount bars, a helper makes the job easier and safer. Having a second person hold the bar level while you drill saves repositioning time and typically cuts 2-3 minutes per window.
What is the fastest type of window security bar to install?
Telescopic frame-mount bars are the fastest to install at 15 minutes per window. The SWB Model A extends to fit the window width, locks with a set screw, and attaches with 4-8 screws through pre-drilled brackets. No cutting, welding, or custom fitting is required. Tension-fit and adhesive-mount bars are even faster (5-10 minutes) but provide less security than screwed installations.
Do I need special tools to install window security bars?
For frame-mount installation, you need three basic tools: a cordless drill or driver, a tape measure, and a level. These are standard household tools that most homeowners already own. For masonry-mount installation on brick or concrete, you additionally need a rotary hammer drill with masonry bits and a wrench for tightening expansion anchors. SWB products include the anti-tamper security bit needed for the fasteners.
How long does professional window bar installation take?
Professional installers typically complete frame-mount bars in 8-12 minutes per window and masonry-mount bars in 20-30 minutes per window. A professional can complete a typical 8-window home in 1.5-2 hours for frame-mount work or 3-4 hours for masonry-mount work. Professionals work faster because they have done hundreds of installations and carry purpose-built jigs and tools that reduce measurement and alignment time.
Can I install window bars in the rain or cold weather?
Frame-mount installation can be done in any weather since you are working from inside the house. Exterior masonry-mount installation should be done in dry conditions because wet masonry affects anchor holding strength and makes drilling more difficult. Cold weather does not affect the installation process itself but may make working outdoors uncomfortable. There is no minimum temperature requirement for mounting steel bars — they perform identically in all climates once installed.
