Replacement patio door supply, installation and full-unit sliding patio door replacement across Ottawa and the Ottawa Valley — energy-efficient glass, weather-tight seals, and smooth operation built for Ottawa winters. This service covers new patio door installation and complete sliding door replacement; roller, track and glass-only repairs are handled through our patio door repair service.
When repair is not enough, we supply and install replacement sliding patio doors sized for Ottawa weather.
We provide replacement patio doors in Ottawa: measuring, supplying and installing a new sliding or French patio door when the old unit is past economical repair. At Fix My Door Now Ottawa, we replace complete patio door units for homes and cottages across the region, to a standard that holds up to Ottawa weather. If your existing patio door only needs rollers, tracks, locks or seals, start with Patio Door Repair Ottawa or Sliding Door Repair Ottawa. Fogged or broken glass only? See patio door glass replacement instead of replacing the whole unit.
Panels come out so rollers, tracks, and seals can be set correctly before the door goes back in.
Patio doors are not a generic, one-size-fits-all install. The opening has to be measured and squared to a tight tolerance, the threshold has to sit dead level, the frame has to be set so the panels meet and seal correctly, and the exterior has to be flashed and air-sealed to keep water out of the wall behind the frame. Get any of that wrong and you end up with the exact problems people call us to fix on older doors: sticking panels, cold drafts, condensation and ice in the track. That’s why we treat the installation itself as the most important part of the job.
Sliding patio doors are the most popular style in Ottawa homes, and for good reason. Because the panels glide horizontally on a track rather than swinging into the room, they take up zero floor space — perfect for a kitchen, dining room or bedroom where a swinging door would be in the way. A modern slider gives you a broad, unobstructed view and a large, easy opening to the outdoors. When we supply and install a new sliding patio door, we set it on a quality roller-and-track system, level the threshold so the panel rides true, and adjust everything so the door slides with a single light push and locks square the first time. The result is a door that slides smoothly and seals properly, which an old, worn-out slider often no longer does.
French patio doors swing open on hinges, usually as a matched pair, and they bring a more traditional, architectural look to a home. They create a generous, welcoming opening — ideal where you want a wide, dramatic threshold to a patio or garden. Because the panels are heavy glass and depend on precise hinge and lock alignment, French doors have to be installed and hung with real care: the pair must meet cleanly in the middle, the multi-point lock must engage smoothly, and the astragal and seals must close tight against drafts. We install French patio door systems so the doors hang true, latch on the first try, and seal all the way around, giving you the classic look without the alignment headaches a poor install would create.
Most of the patio door work we do is a full patio door replacement — removing an older unit that has reached the end of its life (fogged insulated glass, a swollen or rotting frame, failed seals, or a door that will no longer slide or close tight) and installing a new sliding patio door in its place. We pull the old unit, prepare the opening, check carefully for hidden moisture damage behind the existing frame, and set the new complete sliding door unit so it is flashed, sealed and adjusted correctly. For a brand-new opening where there wasn't a door before, we handle the rough framing too — sizing, squaring, heading and supporting the opening before the new patio door goes in. Either way, you deal with one crew, one flat-rate quote, and one guarantee that covers both the door and the work.

A patio door is mostly glass, which makes it one of the largest potential weak points in your home's thermal envelope — and one of the biggest opportunities to improve it. New sliding and French patio doors use double- or triple-pane insulated glass units with low-E coatings and inert gas fills that hold heat in far better than the single-pane or failed-seal glass in an older door. Paired with modern multi-point seals and weatherstripping, a properly installed new patio door cuts drafts, reduces condensation on the glass, and takes a real bite out of your winter heating bill. For many Ottawa homeowners, swapping a tired old patio door for a well-sealed new one is one of the most cost-effective comfort upgrades available.

Ottawa's freeze-thaw winters are brutal on patio doors, and a new door is only as good as the installation behind it. Water that gets past the exterior of a patio door in summer will freeze in winter and, over a few seasons, can do serious damage to the structure behind the frame. We flash and air-seal every installation to a standard built for this climate — not to the manufacturer's bare minimum. We make sure the bottom track drains properly so meltwater can't pool and refreeze, set the door so it seals tight against driving snow and wind, and confirm the interlock and weatherstripping close cleanly. Done this way, a new patio door shrugs off the winter instead of developing the drafts and ice jams that plague a poorly installed one.
Not every problem patio door needs replacing, and we’ll tell you which option makes sense. If the frame is sound and the trouble is worn rollers, a damaged track, failing seals or tired hardware, a focused repair on patio door repair or sliding door repair can get the door working again for much less than a new unit — including patio door roller replacement, sliding door roller repair, or sliding door track repair when that is the real fault. Choose full patio door replacement here when the complete unit is damaged, the frame or opening needs structural work, repair is no longer economical, or you simply want a new sliding patio door. Glass-only fogging or a broken pane with a sound frame belongs on patio door glass replacement, not here. Not sure? Send a photo and we’ll quote both repair and replacement.
We keep the process simple and transparent from the first call to the final test of the lock. It starts with an accurate measurement of your opening and a conversation about the style — slider or French — the glass, and the look you're after. You’ll get a clear, flat-rate quote before any work begins. On installation day we protect your floors, remove the old door cleanly, and prepare the opening — repairing any damage and squaring the frame — before setting the new door, shimming it level, and flashing and sealing the exterior. We finish by adjusting the rollers or hinges, testing the glide or swing and the lock, and walking you through how everything works. Most replacements are wrapped up in a single day.
