Temperature swings in the Eastern Townships are sharper than on the Montreal plain: sealant works harder there, and a joint rated to hold down to -29 °C makes all the difference over time.

Frequently Asked Questions
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, Longueuil, Brossard, Saint-Hubert, Boucherville, Saint-Bruno-de-Montarville, Saint-Lambert, Candiac, all of Greater Montreal and the Estrie region.
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.
