What Sliding Door Lock Problems Do We Fix?
Mortise lock failures, broken latch handles, stuck thumb turns, and worn keeper holes. Sliding door locks take a beating in Florida. The salt air corrodes the internal mechanism, the handle springs fatigue, and the keeper wears out from thousands of open-close cycles.
The most common fix is a mortise lock replacement. That's the rectangular lock body that sits inside the door frame. When it fails, the latch won't engage or the thumb turn spins freely. We pull the old one and drop in a new mortise lock that fits the existing cutout.
Should You Add a Security Bar to Your Sliding Door?
Yes, if you don't have one already. A security bar (also called a charlie bar) sits in the track and prevents the door from sliding open even if the lock is defeated. They cost $25-$40 installed and add a significant layer of protection.
According to the National Crime Prevention Council, sliding glass doors are one of the most common residential entry points for burglars because the factory locks are often weak. A security bar plus a working mortise lock makes forced entry very difficult.
Common Questions
How much does a sliding door lock repair cost?
Most repairs run $75-$125. Full mortise lock replacement is $100-$200 depending on the brand. We carry replacement parts for the most common door brands in South Florida.
Can you fix a sliding door that won't lock?
Yes. Usually it's the mortise lock or the keeper. Sometimes the door is off-track and the latch can't reach the keeper. We diagnose the actual cause and fix it.
Do you carry replacement mortise locks?
We carry universal and brand-specific mortise locks for Andersen, Pella, PGT, and others. If your door uses an unusual lock body, we can source it within 24-48 hours.
What's a security bar and should I get one?
A metal or wood bar that sits in the track to prevent the door from sliding. Costs $25-$40 installed. Highly recommended as a secondary security measure.
