View Window Mart OttawaBefore you hire in Kanata
In Ottawa replacing doors or windows does not require a building permit, provided they go back into the same size opening.
Widening or cutting a new opening changes that, and basement bedrooms have their own egress requirements. Exempt from a building permit still means the work must comply with the Ontario Building Code and any applicable law, such as the Zoning By-law.
Designated heritage buildings and properties inside a Heritage District Overlay are not covered by these exemptions, and the City asks owners to confirm with a Building Client Service Centre before starting.

Common questions
Hiring in Kanata
Kanata is Ottawa's west-end tech hub, a mix of established 1990s and 2000s subdivisions in Kanata Lakes, Bridlewood, and Katimavik plus newer builds further west. Because much of the housing stock is now 20 to 30 years old, the most common projects here are first roof replacements, deck rebuilds, window and door upgrades, and basement finishing. The service businesses below serve Kanata and the wider west end.
A great window installed poorly still leaks air. Ask how they insulate and seal around the opening, and whether they replace rotten framing they find.
Look for a low U-factor and an ENERGY STAR rating suited to Ottawa's climate zone. A good installer explains the rating rather than just selling a brand.
