Window locks are the most ignored locks on your Treasure Coast home - and often the biggest security gap. Most homeowners never think about them until a window sticks, a sash lock breaks, or an inspection finds the hardware non-compliant with current code.
Florida building code and most HOA standards require functioning window locks on every accessible ground-floor window. Beyond code, window locks are the most common bypass point for opportunistic burglars - a sliding window with a broken cam lock can be opened from outside in seconds.
Treasure Coast Locksmith repairs window locks on every common window type: double-hung sash windows, single-hung windows, casement windows, awning windows, sliding windows, and impact-rated hurricane windows. We stock the common brands and install new locks onsite.

Window hardware fails in predictable ways after years of Florida environmental exposure.

Window security and Florida code
Window locks are governed by a mix of Florida Building Code, IRC residential code, and local HOA standards. Ground-floor accessible windows are required to have functioning locks that prevent outside opening. The specific requirements vary by window type, but the general principle is that every window less than 10 feet above grade must be lockable.
For impact-rated hurricane windows, the lock hardware is part of the overall impact rating. Miami-Dade NOA approval testing includes the lock assembly, so replacement hardware must also be NOA-approved or the window loses its code compliance. We verify NOA status on every impact window hardware repair.
Beyond code, window security has a meaningful effect on home insurance premiums in Florida. Many insurers require functioning window locks for full coverage, and some offer discounts for upgraded keyed window locks or impact windows with NOA-rated hardware. It's worth checking with your insurance agent whether a window lock upgrade translates to a premium discount.
Sash lock design has evolved over the years. Older double-hung windows use a cam-style sash lock that rotates to engage a keeper on the lower sash. These are simple and reliable but provide minimal security - a thin blade can bypass most of them.
Newer sash locks use a sliding bolt or gear-driven mechanism that resists bypass attacks. For meaningful security, we often recommend upgrading old cam locks to the gear-driven designs.

Window security tips
- Test every window lock twice a year. Windows that aren't used regularly often have silently failed locks.
- Lubricate sash locks annually with dry graphite or silicone. Never oil.
- For ground-floor windows, consider upgrading to keyed locks. The cost is minimal and the security improvement is real.
- Never paint over a window lock. It seizes the mechanism and requires rebuild to fix.
- Check HOA requirements before replacing window locks. Many associations require specific hardware styles.
- If a sash rattles in wind, the lock keeper is worn or the sash is loose. Fix both at the same visit.

Window lock repair FAQs
Common questions from Treasure Coast homeowners about window lock issues.
How much does window lock repair cost?
Single sash lock replacement runs $65 to $95 per window installed. Cam lock replacement for sliding windows runs $55 to $85. Casement operator repair runs $95 to $155.
Impact-rated hurricane window hardware runs $125 to $195 per window. Bulk pricing available on 5+ windows at once.
Can you install keyed locks on my windows?
Yes. Keyed window locks add meaningful security to ground-floor accessible windows. Installation runs $85 to $125 per window including hardware.
We key them to match your house key if desired. Popular on ground-floor bedrooms, bathrooms, and kitchens.
Do you repair impact-rated hurricane windows?
Yes. We service impact windows from PGT, ESW, WinDoor, CGI, Andersen Stormwatch, and most Miami-Dade NOA-approved brands. Replacement hardware must be NOA-compliant to preserve the window's impact rating, which we verify before ordering parts.
Why do my window locks keep breaking?
Three common causes on the Treasure Coast: salt air corrosion (beachfront homes), UV degradation (south-facing windows), and paint buildup from multiple paint jobs (older homes). Each has a specific fix - new hardware, coastal-grade material upgrade, or strip-and-rebuild.
Can you repair a window that won't close or lock?
Yes. The problem is usually alignment - the sash has shifted or the lock keeper is bent. We realign, adjust the keeper, and verify smooth operation.
If the sash or frame is damaged beyond adjustment, we recommend window replacement and can refer a window contractor.
Do you replace casement window operators?
Yes. Casement window operators (the crank mechanism) wear out or break over time. We replace the operator assembly to restore smooth opening and closing.
Most casement operator replacements take 30 to 60 minutes per window.
What brands of window locks do you stock?
We stock Truth Hardware, Andersen, Pella, Marvin, Kolbe, Jeld-Wen, and generic sash lock hardware. For impact windows we stock PGT, ESW, WinDoor, and CGI replacement components. Unusual brands can be ordered within 2-5 business days if we don't stock them.
Will window lock repair affect my home insurance?
Possibly in a good way. Many Florida insurers offer discounts for functioning window locks, upgraded keyed window locks, and impact-rated hurricane windows. Check with your agent before and after the upgrade.
We provide a written invoice suitable for insurance documentation.
Can you install window locks on an older home with no locks?
Yes. First-time window lock installation is common on older Treasure Coast homes. We add sash locks or cam locks as appropriate to the window type.
Installation takes 20 to 35 minutes per window and usually costs $85 to $125 per window including hardware.
Are window locks required by code?
Florida Building Code requires functioning locks on ground-floor accessible windows in new construction and renovations. IRC residential code has similar requirements. Older homes grandfathered in are not always in compliance but may need upgrades for insurance or HOA reasons.
Can you service double-hung, single-hung, casement, and awning windows?
Yes. All major window types. Double-hung and single-hung use sash locks.
Casement and awning use keeper-and-latch with operator mechanisms. Sliding windows use cam locks. We carry replacement hardware for all types.
Do you work with window contractors?
Yes. We often work alongside window installation contractors to handle the lock and hardware portion of a replacement project. If you're installing new windows, we can rekey, install, or upgrade the locks at the same time as the window install.
Coordination with contractors is common.
