Frequently Asked Questions
My window is foggy between the panes — what should I do?
That's the sign of a failed thermos (sealed unit). No need to replace the whole window: we replace only the foggy sealed glass unit, which is far more affordable. Request a free quote.
Mice are getting in through my soffits — can you help?
Yes. We seal soffits and every entry point where rodents get in. That's exactly why many exterminators refer us: getting rid of mice is pointless if they can come back through the same openings.
How long does caulking last?
Quality caulking, applied with Adfast products on well-prepared surfaces, generally lasts 15 to 25 years depending on sun and weather exposure. That's why our work is guaranteed for 25 years.
When should I redo my window caulking?
As soon as the joint is cracked, detached, blackened or hardened, or if you feel drafts near the windows. A joint that lets water through should be redone quickly to prevent structural damage and mold.
Can caulking be done in winter?
Yes. Unlike many products, ours allow installation down to -29°C. No need to wait for spring to fix an urgent infiltration.
What products do you use?
We use Adfast products exclusively — made in Canada and designed to withstand the extreme temperature swings of Quebec winters.
Do you offer a guarantee?
Yes: our caulking work is guaranteed for 25 years. We don't leave a job site until you are fully satisfied.
Which cities do you serve?
We serve Montreal, Laval, Longueuil, Brossard, Saint-Hubert, Boucherville, Saint-Bruno-de-Montarville, Saint-Lambert, Candiac and all of Greater Montreal.
How much does caulking cost?
The price depends on the number of openings, the condition of the existing joints and access. We offer a free, no-obligation quote, usually within 24 hours.
Do you work on condos and co-ownerships?
Yes. We manage multi-unit projects from start to finish, in coordination with the condo board, with a clear schedule and minimal disruption to residents.
