Sliding Door Repair in Vancouver
If your sliding patio door drags, sticks, won't lock, or has jumped its track, you usually don't need a whole new door — you need the rollers, track, and hardware put right. Sunify Group repairs sliding and patio doors across Greater Vancouver and the North Shore: worn rollers, bent or dirty tracks, broken handles and locks, alignment, and weatherstripping.
Text a few photos of the door and the bottom track to (778) 522-1810 for a fast estimate — most sliding door repairs can be scoped from photos, and we'll tell you honestly whether a repair or a replacement makes more sense.

Sliding door roller replacement
The most common patio door problem by far is worn rollers. When the small wheels under the panel flatten or seize, the door drags on the track, feels heavy, or jumps out of line — and forcing it only chews up the track. Replacing the rollers usually restores a smooth, one-finger glide for a fraction of the cost of a new door.
We carry common rollers and source brand-specific parts when a door needs them, then lift and re-hang the panel, set the roller height, and check that the door seats and locks properly before we leave.
Patio door track repair and cleaning
A bent, dented, or grit-packed bottom track will wreck a fresh set of rollers in months, so track repair goes hand in hand with roller work. We clean out built-up dirt, straighten what can be straightened, and where a bottom track is worn through we can fit a stainless track cap so the rollers run on a clean surface again.
If a track is genuinely damaged beyond a practical repair we'll tell you — but most sliding and patio door tracks can be repaired rather than replaced.
Patio door handle, latch, and lock repair
Handles that spin, latches that won't catch, and mortise locks that won't throw are all common on older sliding doors. We repair or replace patio door handles, lock bodies, keepers, and strike plates so the door secures properly — often on the same visit as roller or track work.
Repair or replace? Honest guidance
Most sliding glass patio doors can be repaired. If the frame is square, the glass is intact, and the door is otherwise sound, new rollers, a cleaned or capped track, and fresh weatherstripping bring it back to like-new operation. Replacement makes more sense when the frame itself is corroded or racked, or when you're upgrading for energy efficiency.
If the sealed glass unit is foggy from a failed seal, we can replace the glass unit inside the existing frame without replacing the whole door. Either way, we give you the straight answer on which path is worth it before any work starts.

- Any brand name or sticker on the frame or door edge

Sliding Door Repair — common questions
Have a different question? Call or text (778) 522-1810.
Most sliding doors can be repaired for a fraction of the cost of replacement. We'll be honest with you about whether repair or replacement makes more sense.
Yes — we can replace the failed sealed glass unit (IGU) inside the existing frame.
Call or text (778) 522-1810 and we’ll let you know our current availability.
Yes. We carry common rollers and source brand-specific parts when needed.
Yes. Heavy patio panels that have jumped the track are usually a roller and track issue, not a reason to replace the door. We can lift and re-hang the panel, replace the rollers, and clean or repair the track so it glides again.
Most patio door tracks can be repaired. We clean out grit, straighten what can be straightened, and where the bottom track is worn through we can fit a stainless track cap so the rollers run on a clean surface again. A damaged track is rarely a reason to replace the whole door.
We lift and re-hang the panel, remove the old rollers, fit new ones (we carry common rollers and source brand-specific parts when needed), then set the roller height and check the door seats and locks properly. Pricing depends on the parts your door takes — we confirm it in writing after seeing photos or on-site.
Yes. Spinning handles, latches that don’t catch, and mortise locks that won’t throw are common on older sliders. We repair or replace patio door handles, lock bodies, keepers, and strike plates — often on the same visit as roller or track work.
