If your sliding door scrapes, sticks, won't latch, or has jumped its track, we fix it — fast. Expert sliding glass door repair across Ottawa and the Ottawa Valley: roller replacement, track repair, alignment and lock work, with same-day service available.
A sliding door should disappear into the wall with a light push — silent, smooth, effortless. When it starts grinding, lurching, or refusing to budge, it goes from invisible to infuriating overnight. At Fix My Door Now Ottawa, sliding door repair is core to what we do, and we approach every job the same way: figure out exactly what's failing, fix that, and leave you with a door that glides like the day it was installed. We work on sliding glass doors in homes and businesses throughout Ottawa and the surrounding Valley, and most repairs are completed in a single visit.
The reason a sliding door fails is rarely a mystery to someone who repairs them every week — but it's easy to misdiagnose if you don't know the system. The slab, the rollers, the track, the jamb, the lock and the keeper all have to be in harmony. Treat the wrong part and the door is heavy again within days. That's why our work starts with diagnosis, not assumptions.
Every repair we do begins with a proper diagnosis, because the symptom you notice is usually downstream of the actual problem. A door that's hard to slide could be failing rollers — or it could be a track full of grit, a panel that's dropped out of level, or a jamb that's shifted. When we arrive, we operate the door and pay attention to where it resists: a door that's heavy from the start points to rollers, one that catches at a single spot points to track damage, and one that drags at the latch end points to alignment. We then physically inspect the rollers, the full length of the upper and lower tracks, the door's level in the opening, and the lock-to-keeper relationship. Only then do we quote the fix. This methodical approach is why our repairs hold instead of unravelling a week later.
Rollers are the heart of a sliding door and the part that fails most often. Each panel rides on wheels housed at the bottom edge, and they endure constant load and abuse. When rollers wear flat, seize, or shatter, the door drops onto the track and you're suddenly dragging metal across metal. Worn rollers don't just make the door heavy — they actively damage the track and set the stage for the panel jumping off entirely. We lift out the panel, fit new heavy-duty rollers matched to your specific door, set them to the correct height, and test the glide before reinstalling. Fresh rollers transform a door you have to fight into one a child can open with a fingertip.
The track is the runway your door depends on, and it lives at floor level where it collects everything — dust, sand, pet hair, road salt tracked in on boots, and the occasional dropped object. Over time it dents, corrodes, and wears a groove where the rollers run. A compromised track will tear up brand-new rollers in short order, so we always assess and address the track as part of any roller job. We thoroughly clean and clear it, straighten minor dents, and where the lower track is worn we install a durable stainless-steel track cap that gives the rollers a smooth, hard surface to run on for years. For severely damaged tracks, we can replace the affected section outright.
Alignment problems show up in telltale ways: a visible gap at the top or bottom of the door, a panel that looks tilted in the frame, a latch that misses its keeper, or a draft along one edge. A sliding door has to sit square and level to seal and lock properly, and over years of use — or after a botched previous repair — it drifts out of true. We bring the door back into alignment by adjusting roller height, squaring the panel in the opening, and resetting the relationship between the lock and the strike. The result is a door that closes flush, latches on the first try, and seals against the weather all the way around.
Security matters on a ground-floor sliding door, so a lock that won't engage is more than an inconvenience. We repair and replace sliding door locks, latches, mortise hooks and handles. The most common complaint — "my door won't lock anymore" — is usually not a broken lock at all, but a door that has settled so the latch no longer lines up with the keeper. We correct the alignment first, then service or replace the locking hardware so it throws cleanly and holds. We can also upgrade tired sliding door locks to more secure hardware and add auxiliary locks for extra peace of mind. If a lock has been damaged in a break-in attempt and the door won't secure, see our emergency door repair service for same-day help.
In Ottawa homes, sliding doors are everywhere — off the kitchen to a deck, from a basement walkout to the yard, between a sunroom and the living space. They get heavy daily use from families, and they're often the first thing buyers and guests notice when they don't work. Our residential sliding door repairs cover the full range: a slider that's become a two-handed struggle, a door that's derailed, a lock that won't catch, or a draft that's driving up the heating bill. We arrive on time in an identified vehicle, diagnose the issue, give you a flat-rate quote up front, and get the door working before we leave — most of the time in one visit. For non-urgent jobs and installations, our full door repair services cover everything else around the home, too.
Businesses rely on sliding doors just as much as homeowners do, and the stakes are higher when a commercial door fails. We service commercial sliding doors for Ottawa storefronts, offices, restaurants, clinics and other businesses, working with the heavier-duty rollers, reinforced tracks and commercial-grade locking hardware these doors use. A commercial slider that won't open smoothly slows customers and staff; one that won't lock is a security and liability problem the moment you close up. We understand that downtime costs money, so we schedule around your operating hours wherever possible and prioritize getting the door secure and functional fast.

The best sliding door repair is the one you never need, and a little maintenance goes a long way. The single most valuable habit is keeping the track clean: vacuum out grit and pet hair regularly and wipe the channel down, because that abrasive debris is what grinds rollers flat and scores the track. Avoid oily spray lubricants, which attract more dirt and turn into a sticky paste — a dry silicone-based product is far better if you lubricate at all. In winter, keep the bottom track clear of ice and packed snow so the door isn't forced against a frozen obstruction. And the moment a door starts feeling stiff, address it: catching a worn roller early is a quick, inexpensive fix, while ignoring it until the door derails or the track is destroyed turns a small job into a big one.
Ottawa's climate is genuinely hard on sliding doors, and our repairs account for it. The freeze-thaw cycle drives ice and meltwater into the lower track, where it refreezes and can jam a door solid or bend a panel that's forced against it. Sand and road salt tracked indoors all winter act like grinding paste on rollers and track alike. And brutal cold makes a worn seal painfully obvious as heat pours out around the door. When we repair a sliding door here, we don't just restore the glide — we make sure the track drains properly, the rollers are sound, and the door seals tight against the frame, so it stands up to the next Ottawa winter instead of failing again at the worst possible time.
