Caulking Services in Mississauga
Caulking is the smallest job on this site and one of the most consequential. The bead around a tub is the seal keeping shower water out of the wall; the sealant around windows and doors is part of what keeps Mississauga winters outside. When it cracks, shrinks, or goes black, it has stopped doing both jobs — and in bathrooms, failed caulking is where most water damage quietly starts.
What’s included
- Bathtub and shower re-caulking
- Sink, vanity, and countertop joints
- Interior and exterior window and door frame sealing
- Trim and baseboard gaps (the standard prep before painting)
- Exterior joints around vents, faucets, and fixtures
- Full removal of old caulk first — new sealant goes onto a clean, dry joint, never over the failed bead
Where it matters most
Tubs and showers in the older subdivisions where the original caulking has been patched over for years, and window perimeters in Port Credit, Lorne Park, and Streetsville homes where ageing sealant has separated from the frame. Caulking pairs with Tiling & Grouting in bathrooms and with Weather Stripping Installation when a whole home is being sealed against drafts.
FAQs
Why not just run a new bead over the old caulking?
Because it doesn’t last and doesn’t seal. New caulk over old, dirty, or mouldy caulk peels early and traps the problem underneath. The old material is cut out, the joint cleaned and dried, and the new bead applied — that’s the version of this job worth paying for once.
The caulking around my tub is black. Will new caulking fix it?
The joint itself, yes — stained, failed caulk comes out entirely. If moisture has been getting through for a long time there can be damage behind the tile or in the drywall; if that’s found, you’ll be told, and Drywall Repair covers the fix.
How long before I can use the shower again?
Sanitary silicone needs curing time before it gets wet — typically around 24 hours. Book the job for a day when that bathroom can rest, or plan around a second bathroom.
Do you caulk windows from outside?
Yes, exterior window and door sealing is part of the service for accessible windows; the quote will confirm which windows are in scope.
