Security doors vs. window bars
Same worry, opposite answers. Bars seal the house; screens open it.
The short answer: you can secure your windows without bars. A woven 316 stainless security window screen is $825 installed per window on our published price list, resists cutting and prying, and lets the window stay open - breeze, view, and daily use intact. Welded bars are cheaper, often a few hundred dollars per window installed, and remain a sensible choice for openings nobody ever opens. On bedroom windows either one must release from inside without keys or tools under California egress rules; for curb appeal and resale, it isn't close.
We sell one side of this comparison, so read us accordingly - but the trade-offs below are the ones any honest contractor would walk you through. One scope note: this page is about windows. If what you are weighing is an ornamental iron door on the front entry, that is its own comparison - see security screen door vs wrought iron door.
The philosophical difference
Bars treat a window as a vulnerability to be sealed. Screens treat it as a feature to be kept. That sounds like marketing until you live with each: a barred window tends to stay shut (opening it feels pointless), while a screened one becomes the most-used fresh-air source in the house. Security you route around isn't protecting much; security you enjoy gets used every day.
Point by point
| Window bars | 316 mesh security screens | |
|---|---|---|
| Upfront cost | Lower - basic welded grids are a few hundred dollars each | Higher - quality screens run from $825 per window installed, priced by glass size |
| Bedroom egress | Requires code-compliant quick-release; many old installs lack it | Egress-rated openable configurations built for the purpose |
| Ventilation & light | Unchanged mechanically, but barred windows tend to stay closed | Full screen-door function; designed to stay open |
| Appearance | Reads as fortification, inside and out | Reads as a quality screen; nearly invisible at distance |
| Resale | Often removed before listing | Increasingly listed as a feature |
| Corrosion | Painted steel needs upkeep, especially coastal | 316 marine-grade alloy; rinse and done |
| Retractable or solar screens instead? | Not a substitute: a retractable insect screen or a solar shade screen is a comfort product with no forced-entry resistance, so bars stay bars | Not a substitute either: a security screen already does the comfort job (insects out, air in) and adds the barrier a retractable or solar screen does not have |
Where bars still make sense
Fairness requires it: for garages, storage buildings, and openings nobody ever operates, simple bars remain a rational, economical choice - egress rules permitting. The case for mesh screens strengthens exactly where you live: kitchens, bedrooms, and the doors and windows that define how the house breathes. What passes on a bedroom window, bars or screens, is spelled out in our California egress guide, and the window product itself is priced on the security window screens page.
Bars vs screens
Common questions
Are window bars legal in California?
Yes, with a critical requirement: bedrooms and sleeping areas must retain an emergency escape route, so bars on those windows need code-compliant quick-release mechanisms operable from inside without keys or tools. Many older installations predate this and would not pass inspection today - worth checking if your home has legacy bars.
Can security screens really match bars for strength?
They solve the problem differently. Bars resist force with a few thick members and their anchor points; woven 316 mesh distributes force across hundreds of tensioned wires clamped into a locked frame. Both present a serious barrier - the difference is that only one of them also works as a screen door you use all day.
What about replacing existing bars with screens?
A common project, especially before selling a home. Bars typically unbolt or come off with a cut at the anchors, holes get patched and painted, and the screen system installs in the same opening - usually a single visit per opening. The before-and-after on curb appeal is dramatic.
Which costs more?
Basic welded bars are cheaper up front - often a few hundred dollars per window installed. Quality stainless security screens cost more (our flat published prices: from $825 per window and $2,475 per door, all on our pricing page) but add daily-use value bars can't: ventilation, unobstructed views, and curb appeal that survives the install. It's a different product answering a broader question.
How do I secure my windows without bars?
Four layers, cheapest first. Sash locks or pin locks stop the window being slid open from outside for a few dollars each. Security film laminated to the glass slows a break-in but does nothing once the glass is out. A woven 316 stainless security window screen sits over the opening in its own frame, resists cutting and prying, keeps the window usable every day, and is $825 installed for glass up to 8 sq ft on our published price list, $100 per additional sq ft above that. For bedroom windows, whatever you choose has to release from inside without keys or tools, because California egress rules apply to security screens and bars alike.
Is a retractable or solar screen a security screen?
No. A retractable screen rolls a light insect mesh across a doorway on a spring, and a solar screen is a shade fabric that cuts glare and heat. Both are comfort products, and good ones, but neither is built to resist cutting, prying, or a push, and neither manufacturer claims otherwise. The full side by side is in our retractable vs security screen door comparison. A security screen is a different object: woven stainless mesh clamped into a rigid frame with its own lock.
