Caulking and sealant replacement in Ottawa
Exterior joints are where water gets in first. We replace failed caulking and sealants on window perimeters, control joints, precast panels and curtain wall interfaces — the most cost-effective defence a building envelope has.
What sealant replacement covers
- Window and door perimeter joints
- Control and expansion joints in masonry and concrete
- Precast panel and curtain wall joints
- Through-wall penetrations and flashing interfaces
- Proper joint preparation: cut-out, cleaning, backer rod, priming
Good sealant work is mostly preparation. Old material is cut out completely, substrates are cleaned and primed, backer rod is sized correctly, and the right sealant chemistry is matched to each substrate — so the new joints last their full service life.
Sealant questions
How long does exterior caulking last here?
It depends on sealant type, joint design, exposure and installation quality — and Ottawa's freeze-thaw swings are hard on all of them. Cracked, hardened or debonded sealant has stopped doing its job regardless of age.
Why do it before bigger repairs?
Failed joints are where water enters. Sealant replacement typically costs a fraction of the masonry, concrete and interior repairs that follow prolonged infiltration.
Can it be done in winter?
Sealants need specific temperature and substrate conditions to bond, so production caulking is scheduled outside the deep-winter window. We plan so weather never compromises adhesion.

Joints past their prime?
We'll survey the building's joints, test adhesion where it matters, and quote a replacement program your board can schedule with confidence.
