What Is Sliding Glass Door Repair?
Sliding glass door repair fixes the parts that make a slider slide, seal and lock, and replaces the glass if it is broken. A sliding door is a heavy glass panel riding on two small rollers along an aluminium track. When any part of that system wears, the door drags, jumps the track, rattles, leaks air or will not lock.
Almost all of it is fixable without replacing the door. The frame, the fixed panel and usually the glass stay. We replace the worn parts and set the panel back up so it runs true.
The Parts That Wear Out
| Part | What goes wrong | Fix |
|---|---|---|
| Rollers | Flattened, cracked or seized nylon wheels | Steel tandem ball-bearing rollers |
| Track | Dents, grooves, grit damage | Stainless track cap or track repair |
| Weatherstrip | Flattened pile, gaps at the interlock | New pile weatherstrip |
| Lock and keeper | Misaligned after the panel drops | Adjust or replace mortise lock |
| Sealed unit | Cracked or foggy | New tempered Low-E unit |
| Screen door | Bent frame, worn rollers | Roller swap or new screen |
Condo Balcony Doors
High-rise sliders in CityPlace, Harbourfront, Humber Bay Shores and Mississauga’s lakeside towers have it harder than most. Wind pressure off the lake, grit, and hundreds of residents’ worth of use on the same door model all add up. They are also often common elements, which means the condo corporation has rules about who can repair them and what parts can be used.
We work with condo PMs on balcony door repairs: getting approval, booking the elevator, matching parts to the building’s door model, and keeping a record for the corporation’s files.
Rebuild Before You Replace
A new sliding patio door installed costs $2,500 and often much more, plus trim and drywall repair. A full rebuild of the existing door costs $690-$950 and usually takes about 3 hours. Unless the frame is warped or rotten, rebuild first.
- Lift the panel off the track onto padded horses.
- Replace the rollers with steel tandem rollers sized to the bottom rail.
- Cap or repair the track so the new rollers have a smooth surface.
- Replace the weatherstrip at the interlock and perimeter.
- Rehang and adjust the panel so it runs level and the lock lines up.
If the glass is also foggy or cracked, we measure for a new unit on the same visit and install it when it arrives. Send a short video of your door sliding and our glass repair crew in Toronto can often tell you the fix before they come out.
