FAQ
Questions about Bay & Bow Windows
Why is my bay window leaking or drafty at the corners?
Bay and bow windows have corner joints, seat boards and roof caps that move and open up over time. We reseal the joints, repair flashing transitions and renew perimeter caulking so water and drafts stay out.
Can you replace one section of a bay or bow window?
Often yes. If one sash or sealed unit has failed, we can replace that section while keeping the rest of the assembly, provided the structure and frames are sound.
How much does bay window repair cost in Toronto?
It depends on whether the issue is sealing, a failed glass unit or structural movement at the projection. We inspect the assembly, explain what is actually failing and quote the repair before any work begins.
Do you repair the roof cap over bay windows?
We service the transitions where the window meets the roof cap and wall - resealing joints and addressing flashing-related leaks around the projection so water stops tracking into the frame.
