Caulking & Sealing

Caulking & re-caulking — bathrooms, kitchens, windows, exterior.

Cracked, peeling, or mouldy caulk isn't just ugly — it's how water gets into walls and subfloors. We strip the old bead completely, treat any mould, and lay clean, smooth, mould-resistant silicone that lasts years.

What's included

  • Old caulk fully removed (not covered over)
  • Surfaces cleaned and mould-treated
  • Premium mould-resistant silicone applied
  • Smooth, even tooled finish
  • Cure-time guidance before water use

Where we caulk

Tubs, showers, vanities, kitchen counters and backsplashes, baseboards in wet areas, window and door frames inside and out, and exterior penetrations. If the joint moves or sees water, it needs the right sealant — not whatever tube was on sale.

Pre-listing secret weapon

Realtors book us for caulking before photos constantly: fresh white lines around tubs and counters read as 'well-maintained home' in every listing photo. It's a small job with outsized impact on buyer perception across Newmarket, Aurora, Richmond Hill, Vaughan, and Markham listings.

Protecting your home from water damage

A failed shower joint leaks slowly for months before you see the ceiling stain below. Re-caulking every few years is the cheapest water-damage insurance there is. We serve Toronto, Mississauga, Brampton, Stouffville, King City, East Gwillimbury, Bradford, and the rest of the GTA.

Frequently asked

Why does my caulk keep going mouldy?
Usually because new caulk was applied over old, contaminated caulk, or a cheap acrylic was used in a wet zone. Full removal plus 100% silicone with mould inhibitors breaks the cycle.
How long before I can shower?
24 hours for full cure on most silicones. We'll schedule so the downtime lands when it's least annoying.
Do you do exterior caulking too?
Yes — window and door perimeters, siding joints, and foundation gaps with exterior-rated sealants. It's one of the cheapest energy-efficiency wins on any home.
