Sliding door lock and handle repair
Broken latches, handles that spin, doors that won't lock. Most are a same-visit fix with hardware we carry on the truck.
A sliding door that won't lock is a security problem, not a convenience problem, and it's usually a 45-minute fix. Most lock failures come down to a worn mortise latch, a stripped handle, or a keeper that's drifted out of alignment.
What this repair actually is
Most sliding doors use a mortise lock — a narrow mechanism set into the edge of the panel that throws a hook or a bolt into a keeper plate on the frame. The handle turns a spindle that drives it. Any of three things can fail: the latch mechanism itself, the handle and spindle, or the alignment between the latch and the keeper.
Why it fails faster in Northeast Florida
Mortise locks sit in the edge of the panel where salt-laden air moves through freely, and the internal springs are the first thing to corrode. But the most common cause we find here isn't the lock at all — it's the door. As rollers wear and the panel drops, the latch stops meeting the keeper at the right height. People assume the lock broke when the lock is fine and the door has sagged a quarter inch. Diagnosing that correctly is the difference between a hardware swap and a repair that actually holds.
Signs you need it
- The handle turns freely without engaging anything
- You have to lift or push the door to get it to lock
- The latch visibly misses the keeper plate
- The key turns but the door still slides open
- The handle is loose, cracked, or pulling away from the panel
How we do the work
- Check panel height and travel first — a sagging door mimics a broken lock
- Test the latch out of the keeper to isolate whether the mechanism or the alignment is at fault
- Adjust roller height or reposition the keeper where alignment is the problem
- Replace the mortise lock, spindle or handle set where the hardware has failed
- Confirm the lock engages fully from both inside and outside before we leave

Questions about locks & handles
Do you carry locks for older doors?
We stock the common profiles. Older and discontinued mortise locks sometimes need to be ordered, and we'll tell you that on the visit rather than after.
Can you add a secondary lock?
Yes. A foot bolt or auxiliary latch is a straightforward add and worth considering on ground-floor doors.
My door locks but feels loose. Is that normal?
No. Play in a locked door usually means the keeper is worn or the latch isn't seating fully, and both get worse. It's worth fixing before it stops locking altogether.
Other repairs we handle
Roller replacement
The repair we do most. Worn rollers are why a door drags, sticks, or takes two hands. We fit sealed stainless assemblies rated for coastal air.
Track repair & replacement
A worn track destroys new rollers within months. We clean and straighten where we can, and replace the bottom track when it's past saving.
Pocket doors
Doors that disappear into the wall are the ones most contractors won't touch. We service hangers and track without cutting your drywall in most cases.
