When repair is no longer the right answer — or when you're building, renovating, or simply upgrading — we supply and install doors across Ottawa and the Ottawa Valley. Interior and exterior, residential and commercial, standard and custom. Measured to fit, hung true, sealed for Ottawa weather.
A door installation sounds straightforward until you're standing in front of a rough opening that isn't quite square, a slab that arrived 3mm too wide, or a pre-hung unit whose hinge placement doesn't match the existing frame prep. Door installation is a trade skill, and the difference between a door that works flawlessly for twenty years and one that sticks, drafts, or fails to latch within a season usually comes down to how well it was installed — not what it cost. At Fix My Door Now Ottawa, installation is work we approach with the same precision we bring to repair, because a door hung wrong is a repair call waiting to happen.
We supply and install doors for homeowners undertaking renovations, builders working on new construction, commercial property owners upgrading entries, and anyone whose existing door has deteriorated beyond repair. We handle the full scope: measuring the opening, sourcing the door, preparing the rough opening if needed, setting the frame, hanging the slab, installing hardware, and weatherproofing the assembly so it performs from day one in Ottawa's climate. You don't need to coordinate between a door supplier and a separate installer — we do both.
The exterior entry door is the first impression of your home and the front line of your security and energy envelope. Installing it correctly means more than getting the slab in the opening — it means ensuring the frame is set plumb and level in a rough opening that may have shifted since the house was framed, shimming and securing it properly so it won't rack with seasonal movement, installing the threshold and weatherstripping so the door seals completely against Ottawa's winters from the first day, and fitting the lockset and deadbolt so the hardware operates smoothly and the strike is anchored into the wall framing. A poorly installed exterior door will be drafty within one winter, difficult to operate within two, and a security liability throughout. We've corrected enough improperly installed doors to know exactly what the shortcuts look like and why they matter.
For exterior doors, we also help with product selection. Steel doors offer excellent security and thermal performance and hold up well to Ottawa's freeze-thaw cycling. Fibreglass doors resist denting and don't rust, and modern fibreglass can be stained to look like wood without the maintenance concerns. Wood doors remain popular for their aesthetics but require more attention in Ottawa's climate — proper finishing, periodic maintenance, and the right species selection for exterior exposure. We guide you through the options honestly, based on your priorities and your home's specific exposure. For a sense of the work involved, see this exterior 8ft custom door installation in Ottawa from our project gallery.
Interior doors don't face weather, but they still need to be hung correctly to operate without binding, latch cleanly, and sit square in the opening. New interior door installations come up most often during renovations — opening up a wall, creating a new room division, upgrading hollow-core builder doors to solid-core for sound isolation, or replacing a damaged door in a rental unit. We measure the existing opening or the new rough opening, source the pre-hung unit or supply the slab for an existing frame, and hang it so it swings freely, sits centred in the frame, and latches without force. We also install the hardware — passage sets, privacy locks, or whatever configuration the room requires.
For rental property owners and property managers, interior door installation and replacement is a recurring maintenance need, and we can service multiple units efficiently on the same visit. Closet doors are a common interior project too — see our 7ft closet door installation and 8ft closet door installation in Ottawa.
New sliding and French patio door systems require precise installation to perform correctly — the threshold has to be level to a tight tolerance, the frame has to be set so the panels align properly, and the rough opening has to be correctly sized and flashed so water doesn't find its way into the wall assembly behind the frame. Ottawa's climate makes flashing and sealing the exterior of a new patio door installation particularly important: water that gets behind the frame in summer will freeze in winter and can cause significant damage to the surrounding structure over a few seasons. We install sliding and French patio door systems with the flashing and air sealing done to a standard that Ottawa's weather demands, not to the minimum the manufacturer's instructions specify.
We work with standard sliding door widths for replacement installations, and for new openings we handle the rough framing preparation so the opening is correctly sized and squared before the door goes in. If you're replacing an existing patio door that has deteriorated beyond repair, we remove the old unit, assess and address the rough opening and any moisture damage behind the frame, and install the new system so it performs without the problems the old one had. If your existing door is sound and only the hardware is failing, repair is usually the better value — see our patio door repair and sliding door repair pages before deciding to replace.

Fire-rated door assemblies — the door, frame, hardware, and any glazing all certified together as a unit — are a code requirement in specific locations in commercial and multi-unit residential buildings in Ottawa. Stairwell entries, mechanical room doors, suite entry doors in apartment buildings, and certain corridor doors all require fire-rated assemblies with the appropriate UL or cUL listing. The installation of a fire-rated door is not the same as installing a standard door: the frame has to be anchored correctly, the door has to be fitted within the required clearances, the hardware has to be compatible with the rating, and the assembly has to be documented for the building's fire safety records.
We install fire-rated door assemblies in Ottawa commercial and multi-unit residential buildings, supply the required hardware, and provide the installation documentation building owners need for compliance. We also flag when an existing fire door has been modified, propped, or had incompatible hardware installed — all of which can void the rating and create liability. This work pairs with our commercial door repair service.
High-security doors are a category that covers a range of applications: a homeowner who wants a door that will genuinely resist forced entry, a business that needs a reinforced entry on a high-value storage area, or a property with a specific threat profile that standard residential hardware doesn't address. High-security installations go beyond the door slab — they include reinforced frames with continuous steel backing behind the jamb, multi-point locking systems that engage at three or more points around the door perimeter rather than a single deadbolt throw, heavy-duty hinges with anti-removal pins, and in some cases door and frame combinations that meet specific forced-entry resistance ratings. We assess the application, recommend the appropriate product combination, and install the complete assembly so the security performance is actually achieved — because a high-security door in a standard frame with a builder-grade strike is not a high-security door.
New aluminum storefront entries for Ottawa businesses involve both the door system and the surrounding frame assembly — the transom, sidelites, and threshold configuration that make up the complete commercial entry. We install aluminum storefront systems for new commercial tenancies, building renovations, and replacement of failed or outdated entries. Commercial entry installation requires coordination with the building's mechanical and electrical systems when access control or electric strike hardware is part of the scope, and we work with those trades to ensure the door installation doesn't create conflicts downstream.
For businesses opening in a new space, the entry door is the first thing customers interact with, and an entry that looks tired, operates poorly, or doesn't close properly sets the wrong tone before anyone gets inside. We install commercial entries that operate smoothly through heavy daily traffic and stand up to Ottawa's climate without the maintenance issues that poorly installed commercial aluminum develops.
Every door installation we do follows the same sequence: measure the rough opening for plumb, level, and square before the door arrives; confirm the door specification matches the opening; prepare the opening — shimming, trimming, or blocking as needed; set and secure the frame; hang the slab and verify operation before fastening anything permanently; install and adjust all hardware; weatherstrip and threshold the assembly; and test the complete door through its full range of operation including locking. We don't cut the sequence short because the job is running long. A door that passes all of those checks on installation day will still be operating correctly years later.
