One manufacturer, one team, the entire capital
Unisson Groupe builds its windows and doors at its own factory in Saint-Laurent, Montréal, roughly 200 km from Parliament Hill. Because we are the manufacturer, there is no distributor or subcontracted installer between you and the people who made your windows. The same company that measures your openings is the one that installs the finished product.
Our crews travel to Ottawa on planned routes, which lets us serve the urban core, the older inner suburbs and the growing edges of the city with the same process. You get one point of contact from the first visit to the final walkthrough, and service in the official language you prefer.
- Free in-home measurement by our own technician
- Made-to-measure production in our Saint-Laurent factory
- Delivery and installation by Unisson crews, not subcontractors
- Financing options available for larger projects
Matching the right window to Ottawa's mixed housing stock
Few cities put so many building eras side by side. Century-old brick houses in Centretown and Sandy Hill sit a short drive from postwar bungalows in Alta Vista and subdivisions in Kanata and Stittsville that went up only a generation ago. Each era brings different opening sizes, wall depths and exterior finishes, so a one-size catalogue rarely works.
During the free visit we look at how your home was built before recommending a style. If your street lies within one of Ottawa's heritage conservation districts, it is wise to check the City's requirements before changing how the front of the house looks; we can help you choose profiles and colours that respect the original character.
- Older brick homes: narrow-profile casement windows or hybrid aluminum-clad frames in heritage colours
- Postwar bungalows: large picture windows flanked by operable units
- Newer suburban homes: vinyl sliders, double-hung or awning windows for basements and bathrooms
- Living-room statements: bay and bow windows built to your exact opening
Glass engineered for a very cold capital
Ottawa is known for long stretches of deep cold and hot, humid summers, so glazing has to work hard in both directions. Our ENERGY STAR® certified windows combine Low-E coatings with argon-filled sealed units to slow heat loss in January and cut solar gain in July. Warm-edge spacers help keep the inside pane warmer, which reduces the condensation that often shows up on older glass.
For north-facing rooms, bedrooms over garages or homes near busy roads, triple glazing is often worth considering for both comfort and sound. We will explain the trade-offs honestly during your estimate, and you can read more in our guide to triple-glazed windows.
Entry and patio doors that stand up to freeze-thaw
Front doors in Ottawa face road salt, driving snow and dozens of freeze-thaw swings each season. Our steel and fiberglass entry doors are built with insulated cores and tight weatherstripping, and can be ordered with sidelites, transoms and decorative glass to suit the house.
At the back of the home, a sliding patio door or a hinged garden door can transform how you use a deck or yard. We manufacture both to measure and install them with proper sill pans and sealing so they keep water and cold air out for years.

Ottawa Windows & Doors — FAQ
Can a Montréal manufacturer really handle a project in Ottawa?
Yes. We schedule measurement visits and installation crews on regular routes to the Ottawa area, so distance does not change the process. Your windows are built in our Saint-Laurent factory and installed by our own team, not a local subcontractor.
How many visits does a typical Ottawa project need?
Usually two: a free in-home visit to measure and discuss options, then the installation itself once your windows and doors come off our production line. We confirm dates with you in advance so you know exactly when the crew will arrive.
My house is in an older central neighbourhood. Can you match its look?
We offer narrow-profile frames, hybrid aluminum-clad options, grilles and a wide range of exterior colours that suit older brick and wood homes. If your property is in a heritage conservation district, we recommend confirming the City's rules before the order is placed.
Is service available in both English and French?
Absolutely. Our advisors and crews work in both languages, and your quote and paperwork can be prepared in whichever you prefer.
