A sliding glass door should move with one finger. When it takes your shoulder, your hip, and a running start, something inside the door has failed — and in South Florida it's almost never the door itself. Salt air, humidity and years of sand grinding through the track destroy the working parts: the rollers seize, the track pits, the latch drifts out of alignment. The glass and frame are usually fine.
That's why replacement is almost always the wrong first answer. A new impact-rated door system can run into the thousands per opening, plus permits and weeks of lead time. A professional repair rebuilds the parts that actually failed — typically in a single visit — and leaves you with a door that glides better than the day it was installed. We repair every major brand and vintage of sliding door found in South Florida homes and condos, from 1970s originals to current impact systems.
Signs your sliding door needs repair
- The door takes two hands (or a shoulder) to open or close
- It grinds, scrapes, or screeches along the track
- The door jumps, wobbles, or catches at the same spot every time
- You can see daylight, or feel warm air leaking, around the closed panel
- The latch no longer lines up, so the door won't lock securely
- The door has dropped and now drags on the track or threshold
What a repair visit includes
- Full diagnosis of rollers, track, alignment, lock and weatherstripping — not just the symptom you called about
- Removal of the panel and replacement of worn rollers where needed
- Track cleaning, dressing, or stainless-steel capping for pitted rails
- Realignment and height adjustment so the panel sits square and latches cleanly
- Lubrication with the correct silicone products — never grease, which traps sand
- A glide-and-lock test with you before we leave
