Window bars, storefront bars and interior security cages.

Window security bars
Fabricated to the exact window opening and finished to blend in or stand out, depending on what the property wants. Anywhere the window is a fire-egress route — most bedrooms fall into this category — we build in an interior quick-release so the bars don’t become the thing that traps someone in a fire. That is not optional on a job that qualifies, and we will flag it even if it is not asked for.
Fire egress, stated plainly
Building and fire codes generally require security bars on a bedroom or other egress window to have an interior release that a person can operate without a key or tool, from inside, in the dark. Exact requirements vary by jurisdiction and by whether the window is legally required as an escape route. We build to the requirement that applies and can tell you what that means for your windows — for anything you’re unsure about, your local fire marshal has the final say.
Storefront security bars
Fixed bars are the simplest and least expensive option for a storefront that stays secured around the clock. Hinged, foldable bars cost more but let the glass stay open and visible during business hours and swing shut and lock at close — the common choice for retail that wants an inviting storefront by day and real security overnight. Pattern can be a plain functional grid or a decorative scroll design; both do the same job structurally.
Interior security cages
Built to enclose a specific interior space — a stockroom, a server closet, evidence or inventory storage, a section of a warehouse floor. Panel size, mesh or bar spacing and door hardware get specified to the room, not assembled from a generic kit sized to the nearest stock dimension.
How the estimate works
Text a photo of the window, storefront glass, or the room that needs a cage, with rough dimensions if you have them. For anything involving fire-egress requirements we’ll ask a few questions about the room’s use before quoting, since that changes what the bars are legally required to do.

What people ask before booking.
Do window security bars have to have a quick-release for fire safety?
For a bedroom window or anywhere used as a fire escape route, yes — most building codes require an interior quick-release mechanism on security bars covering an egress window, so occupants can get out without a key in an emergency. We build to that requirement on anything that qualifies. If you are not sure whether a specific window counts, ask your local fire marshal or building department; we can point you to what to ask but the department has the final word.
What is a security cage used for?
Interior security cages enclose a specific area inside a building rather than a whole perimeter — a stockroom, a server closet, a storage cage in a warehouse, a section of a retail floor after hours. Panel size, mesh or bar spacing, and whether it needs a lockable door all get specified for the actual space rather than built as a generic kit.
Do storefront security bars have to look industrial?
No — bar spacing and pattern are flexible as long as the spacing does its job. A lot of storefronts use a decorative scroll or grid pattern that reads as architectural rather than purely functional. We can build either the plain, purely functional version or something with more design to it, at different cost.
Fixed or removable/foldable bars?
Fixed bars are simpler and cheaper. Hinged, foldable bars cost more but let a storefront open up during business hours and secure the same opening at close — common on retail glass where you don’t want the bars visible all day. We’ll ask how the space is actually used before recommending one over the other.
