Impact Sliding Glass Door Repair
Impact-rated sliding glass doors use thick laminated glass in a heavier frame, so their rollers, tracks and locks work harder than a standard slider’s. When an impact door gets hard to move, drags or won’t lock, the usual fix is new heavy-duty rollers, a trued track and an adjusted lock — not a new door.

More glass, more load on every part.
An impact slider is built to stand up to storms, which makes the panel heavier than a standard door. The rollers under it carry that extra load every time the door moves, so they flatten and wear sooner. Worn rollers let the panel sit lower, the track wears where they ride, and the lock stops lining up. It’s the same handful of wear parts as any slider — they just get a harder life.
Signs your impact door needs service.
Hard to get moving
The door takes a shove to start and fights you the whole way. The rollers are usually worn or seized.
Grinding or scraping
A gritty, metal-on-metal sound means the rollers are failing or the panel is dragging on the track.
Won’t latch or lock
The latch misses the keeper or you have to lift the handle to lock it. The panel has shifted or dropped.
Pitted or worn track
Near the coast, salt air pits the track and the rollers start to bump. The track gets repaired or capped in stainless.
Rollers, tracks, locks and alignment.
Heavy-duty rollers
Worn rollers swapped for heavy-duty, sealed-bearing rollers built for the load. Roller replacement →
Tracks & stainless capping
Worn or pitted tracks repaired, or capped in stainless so the new rollers ride smooth. Track repair →
Locks & latches
Latches re-aligned, sticky handles and worn locks repaired so the door locks without a fight. Lock repair →
Alignment
The panel set back to the right height and square in the frame, so it slides, seals and locks the way it should.
We repair impact sliders from many makers, including PGT and CGI doors. If the laminated glass itself is cracked, mention it when you call and we’ll tell you the best way to handle it.
Before and after the storm.
Before the season
Make sure the door slides freely, closes fully and locks without lifting the handle. Clear the track and the weep holes. Our hurricane prep guide has the full checklist.
After a storm
If the door got hard to move, came off the track or won’t lock after a storm, call us before forcing it. If you’re filing a claim, see how we help with insurance claim repairs.
Why do impact sliding doors get hard to move?
Impact doors use thick laminated glass in a heavier frame, so the rollers carry more load on every slide. Over time the rollers wear down and the track wears where they ride, and the door starts to drag. New heavy-duty rollers and a trued track usually bring the glide back.
Can you repair an impact door without replacing it?
In most cases, yes. What wears out on an impact slider is the same as on any slider: the rollers, the track and the lock. Those are repairable parts. Free estimate before any work.
Do you work on PGT and CGI impact doors?
Yes. We repair impact sliding doors from many makers, including PGT and CGI doors. We are an independent repair company, not a dealer for any manufacturer.
My impact door won't lock since the last storm. What happened?
Usually the panel has shifted or dropped slightly, so the latch no longer lines up with the keeper. Adjusting or replacing the rollers and re-aligning the lock fixes most of these. If the glass is cracked, tell us when you call.
Is there a warranty on impact door repairs?
Yes. Every repair carries a 1-year warranty on parts.
