View Big City Windows & DoorsBefore you hire in Nepean
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.
Source: City of Ottawa: Projects not requiring Building Permits. Confirmed 2026-08-23. Thresholds change, so check before you build.
Common questions
Hiring in Nepean
Nepean is a large, established area in Ottawa's central-south, covering neighbourhoods like Barrhaven's northern edge, Bells Corners, and Centrepointe. Its housing stock skews older than the newer suburbs, so renovations, roof and window replacements, basement waterproofing, and mature-tree work are all common here. Central Nepean's location makes it easy to reach for most Ottawa service businesses, including those below.
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.
