What Window Lock Problems Does Triton Locksmith Fix?

Broken sash locks, stuck casement cranks, loose crescent latches, worn sliding window catches, and jammed jalousie operators. Florida's humidity corrodes window hardware faster than anywhere else in the country. The aluminum and zinc components oxidize, the springs weaken, and eventually the lock stops engaging. We see window locks fail in South Florida after 5-7 years that would last 15+ in a dry climate.

Here are the most common window lock repairs we do, ranked by frequency:

  • Double-hung sash lock won't latch: The keeper gets loose from repeated use and the lock no longer catches. Fix: reposition keeper or install longer screws. $55-$75. Takes 10 minutes.
  • Casement window crank broken or stripped: The crank handle spins but the window doesn't move. The operator gear is stripped. Fix: replace the operator mechanism. $80-$120. Takes 20-30 minutes.
  • Sliding window latch broken: The spring-loaded catch snapped or the tab broke off. Fix: replace the latch assembly. $55-$85. Takes 15 minutes.
  • Crescent latch loose or corroded: The half-moon shaped lock on older double-hung windows. Screws pull out of softened wood or the mechanism corrodes. Fix: reMount with longer screws or replace. $55-$75.
  • Jalousie window operator seized: Older South Florida homes have jalousie (louvered) windows. The crank mechanism seizes from corrosion. Fix: lubricate or replace operator. $65-$100.

Do Window Locks Actually Prevent Break-Ins?

They're a deterrent, not a barrier. According to FBI burglary data, about 23% of residential break-ins happen through windows. A working window lock won't stop someone with a brick, but it will stop the casual opportunist who walks around a house testing windows looking for one that slides open. And that's most burglars.

Think about it from the burglar's perspective. They want an easy target. An unlocked window is silent and fast. A locked window requires force, makes noise, and draws attention. Most residential burglars told researchers in a University of North Carolina study that they would move on to an easier target rather than force a locked window. Your window lock doesn't need to be unbreakable. It just needs to make your house harder than the next one.

What Are Secondary Window Locks?

Additional locks installed alongside the factory hardware for extra security. We install three types:

  • Pin locks ($15-$20/window): A metal pin that goes through a hole drilled in the window frame, preventing it from being slid open. Simple, effective, and invisible from the outside. Works on double-hung and sliding windows.
  • Window charley bars ($20-$25/window): A telescoping metal bar that sits in the track of a sliding window, preventing it from being opened even if the latch is defeated. Same concept as a sliding door security bar.
  • Keyed window locks ($25-$40/window): A lock that requires a key to open the window. Replaces the factory latch with a lockable version. Best for ground-floor windows in high-risk areas.

For ground-floor windows, we recommend at minimum a pin lock plus the factory latch. Two layers of security for under $20 per window. If you have an in-home security assessment, we'll identify which windows are most vulnerable and prioritize those.

How Much Does Window Lock Repair Cost?

$55-$120 depending on the window type and repair needed.

  • Sash lock tightening or replacement: $55-$75
  • Sliding window latch replacement: $55-$85
  • Casement operator replacement: $80-$120
  • Jalousie operator repair: $65-$100
  • Secondary lock installation (per window): $15-$40

If you need multiple windows repaired on the same visit, we work through them efficiently. The first window takes the longest because we're diagnosing. Each additional window goes faster. We don't charge a separate service call for each window on the same trip.

Why Do Window Locks Fail Faster in South Florida?

Humidity, salt air, and UV radiation. The average relative humidity in South Florida is 73%. That moisture gets inside the lock mechanism and causes corrosion on the springs, pins, and moving parts. Coastal properties in Deerfield Beach, Pompano Beach, Highland Beach, and Hillsboro Beach deal with salt spray that accelerates metal corrosion by 3-5x compared to inland locations.

UV radiation breaks down plastic components. Many modern window locks use nylon or polymer parts that become brittle and crack after years of sun exposure. The south and west facing windows get the worst of it.

We recommend annual window lock inspections as part of routine home maintenance. Test every lock. If it's stiff, spray it with a dry lubricant (not WD-40, which attracts dirt). If it's loose, tighten the screws. If it doesn't engage at all, call us before it fails completely during a storm.

Can You Repair Windows That Won't Open or Close?

If it's a lock or hardware issue, yes. We fix locks, latches, cranks, operators, and balances (the springs that hold a double-hung window up). If the window frame itself is warped, rotted, or the glass is broken, that's a window company job. But 7 out of 10 "stuck window" calls we get turn out to be a hardware problem we can fix on the spot.

Common "stuck window" causes we fix: painted-shut sash locks, corroded operators, broken balance springs (window falls down when you let go), and track debris preventing sliding. All fixable in 15-30 minutes for $55-$120.
