FAQ
Questions about Weatherstripping, Caulking & Draft Control
How much can new weatherstripping reduce my heating bill?
Air leakage around doors and windows is one of the biggest sources of heat loss in GTA homes. Renewing worn weatherseals and exterior caulking is a low-cost fix that noticeably reduces drafts and helps furnaces run less in winter.
How do I know if my weatherstripping needs replacing?
If you feel cold air around a closed door or window, see daylight at the edges, or the seals look flattened and cracked, they are past their service life. We assess every opening and replace only what has actually failed.
When is the best time to caulk and seal in Toronto?
Late spring through fall is ideal - exterior caulking cures best in moderate temperatures. Booking before November means your home is sealed before the first deep freeze.
Do you seal both doors and windows on the same visit?
Yes. We typically handle weatherstripping, door sweeps and exterior perimeter caulking for all openings in one visit, which keeps the cost per opening down.
