Window replacement for Ottawa buildings
Upgrade your building's energy efficiency, comfort and appearance with professional window replacement for commercial, condominium and institutional properties — planned suite by suite, sealed the same day, detailed as part of the envelope.
Why buildings replace windows
- Fogging between panes — failed insulated glass seals
- Drafts, condensation and cold interior surfaces
- Deteriorating frames, hardware and operability complaints
- Rising heating and cooling costs
- Water infiltration at window perimeters
A window is only as good as its installation. We detail perimeter sealants, flashings and interfaces so the new units perform in Ottawa's climate — and coordinate with any wider envelope program your building is planning.
Window questions
Repair or replace?
When seal failure, frame deterioration or drafts are widespread, unit-by-unit repair usually costs more over time than a planned replacement program. An assessment with real counts settles it.
Can replacement happen with residents in place?
Yes — occupied replacement is standard for condos. We schedule suite by suite with advance notices, and each opening is weather-sealed the same day.
How does this fit with envelope work?
Windows are part of the envelope. Perimeter sealants, flashings and interfaces decide performance, so we detail them as part of the replacement and coordinate with wider envelope scopes.
