WINDOW SECURITY BAR
COST GUIDE 2026
Real prices by product type, installation method, and brand — so you can budget accurately.
The average homeowner overpays 40% on window bar installation — typically by hiring a local fabricator for a custom job when an adjustable system would have done the same work at a fraction of the cost. According to our 2025 survey of 312 SWB customers who had previously gotten contractor quotes, the median quote was $380 per window for custom fabrication. SWB's equivalent solution: $99–$114.
The gap isn't about quality — it's about the business model. Custom fabricators charge for design, metalwork, travel, and installation labor. SWB eliminates all four by shipping a pre-engineered adjustable system direct to your door.
Here's the number that matters most: not the upfront cost, but the cost-per-year-of-protection. At 30+ year lifespan, a $114 SWB bar works out to under $4 per year — while the average burglary loss is $2,900.
Quick Answer
Window security bar cost ranges: DIY adjustable bars (SWB) run $99–$114 per window. Budget big-box fixed bars: $25–$60 (limited sizing, no egress). Professional custom fabrication: $200–$400 per window plus $150–$350 installation labor. For a typical 6-window ground-floor installation, budget $594–$684 for DIY or $1,500–$2,500 for professional installation.

Why Window Bar Prices Vary So Widely
Walk into a Home Depot and you'll find window bars for $25. Call a local ironworker and the quote might come back at $400 per window. Both are “window bars,” but they are fundamentally different products serving different needs — and neither price is wrong, given the product.
The $25 bar is a fixed-size mild steel unit that comes in three widths. If your window doesn't match one of those widths, it won't fit without modification. It has no egress mechanism, meaning it's illegal on bedroom windows in most jurisdictions. And in humid climates, untreated mild steel starts rusting within two years.
The $400 custom bar is fabricated to your exact window size, galvanized or powder-coated, installed by a professional, and comes with a warranty on labor. For commercial properties or high-value residential applications where appearance matters and custom design is needed, that price is entirely justified.
For the vast majority of homeowners, neither extreme is the right answer. An adjustable, galvanized, fire-code compliant system like SWB occupies the practical middle — security equivalent to custom bars at a fraction of the cost, installed in 30 minutes without a contractor. That's the category that most homeowners should be shopping, and it's the one most homeowners don't know exists until they do research.
When to Hire a Pro vs. DIY
The decision isn't about skill — it's about wall type and time. SWB bars are engineered for DIY installation by homeowners with no prior security installation experience. The included hardware, drill template, and printed guide walk through every step. 94% of SWB customers who purchased DIY report completing installation without needing additional help.
The exceptions are masonry walls in older homes where the anchor substrate is unpredictable, or buildings with historic preservation requirements where any drilling must be done by a licensed contractor to preserve facade compliance. In both cases, hiring a professional to install SWB bars (rather than custom bars) still saves 50–60% on product cost.
One scenario to avoid: hiring a contractor who sources their own bars and marks them up before adding labor. Always purchase bars direct and hire labor separately. The markup on “included materials” in contractor quotes frequently adds $100–$200 per window to the project cost. See our installation guide for the full DIY walkthrough.
How Much Do Window Bars Cost?
| Option | Per Window | 6 Windows | Notes |
|---|---|---|---|
| Budget big-box (Grisham, HD) | $25–$60 | $150–$360 | Fixed size, no egress, low security |
| SWB Direct (DIY) | $99–$114 | $594–$684 | Adjustable, fire-code compliant, free ship |
| SWB + pro install | $249–$264 | $1,494–$1,584 | SWB product + $150/window labor |
| Custom fabrication | $200–$400 | $1,200–$2,400 | Pro design + weld + install |
| Commercial heavy-duty | $500–$1,500+ | $3,000+ | Schedule 40 pipe, commercial properties |
5 Factors That Determine Price
Five main factors determine the final price of your window bar project:
Budget options from Home Depot or Lowe's use thin-gauge steel in fixed sizes — cheap but limited. Professional-grade systems like SWB use galvanized heavy-gauge steel with telescoping and modular expansion. The material cost difference is significant, but so is the performance gap.
Fixed-size bars are cheaper upfront but often require buying multiple sizes for different windows — eliminating the savings. SWB's telescopic + modular system covers any window with a single product line, making the per-window cost consistent.
Bedroom windows require quick-release mechanisms under IBC § 1030. Fixed bars without egress require a separate quick-release kit (typically $30–$80 add-on) or a full replacement. SWB's Model A/EXIT includes egress built-in for just $15 more per module vs. Model A.
Installing on masonry requires specific masonry anchors and a hammer drill. SWB's Model B includes the right hardware for masonry. If you hire a professional for masonry installation, expect $200–$400 per window due to the additional time and equipment.
SWB bars are designed to eliminate labor cost. DIY installation averages 15–30 minutes per window using a standard drill — no special skills required. If you hire out, typical window bar installers charge $50–$150/hour. Most homeowners report spending under $150 total on professional installation for 5–6 windows.
Hidden Costs
If you buy bars without egress for bedroom windows, you may need to replace them entirely to pass a home inspection or qualify for FHA financing.
Fixed-size budget bars frequently don't fit — homeowners end up buying multiple sizes. SWB adjustable bars eliminate this waste.
Untreated steel bars require annual rust treatment or replacement in coastal/humid climates. SWB bars are galvanized for 30+ year corrosion resistance.
Some handymen charge retail price for bars then add installation on top. Buying direct from SWB and having a handyman install saves 30–50%.
ROI Analysis
Average residential burglary cost (FBI 2024)
SWB DIY — 6 windows, fully protected
Years of protection after break-even
For a 6-window ground floor installation at $680 (SWB DIY), the break-even is reached after preventing a single break-in attempt. With a 10% annual burglary risk in moderate-crime areas, average payback period is 2–3 years. The bars then last 30+ years — delivering 27+ years of free protection.
