Silicone Around Tubs & Showers
Detailed Description
Cracked or Mouldy Silicone Around Your Toronto & GTA Tub or Shower Is Actively Letting Water Behind the Tile
The silicone bead at the bottom of a shower wall, around a bathtub perimeter, and at the shower door track exists for one reason: to prevent water from getting behind the tile and into the wall structure behind it. When that silicone cracks, separates, or grows mould through its thickness — as it invariably does in the wet environment of a Toronto & GTA bathroom — it stops sealing the joint it was placed to protect. Water follows the gap into the wall cavity, saturates drywall, framing, and in serious cases reaches the subfloor. By the time the problem shows on the surface of a Toronto & GTA home, it’s been developing for much longer than most homeowners assume.
At CNG Contracting, tub and shower silicone replacement in Toronto & GTA is done completely correctly. Full removal of all existing sealant — not application over top — surface preparation, and fresh mould-resistant silicone applied cleanly and consistently. The result is a sealed joint that performs properly, looks clean, and lasts significantly longer than product applied over deteriorated old sealant.
Why Complete Removal Is Non-Negotiable in Toronto & GTA Bathrooms
- New Bonds to Old, Not Substrate: Silicone applied over existing sealant doesn’t bond to the tile or tub — it bonds to the failing product underneath. When the old product fails, both layers come off together.
- Mould Below the Surface: Bathroom silicone that’s showing black streaking has mould within the sealant body — surface cleaning removes the appearance, not the mould. Complete removal and replacement is the solution.
- Proper Cure Required: Silicone in wet areas needs full cure time — 24 hours minimum — before water contact. Applied correctly and cured properly, it provides years of reliable performance in your Toronto & GTA bathroom.
- Mould-Resistant Formulation: Standard silicone and bathroom silicone are different products. We use mould-resistant formulations specifically designed for the sustained wet exposure of Toronto & GTA home bathrooms and showers.

Frequently Asked — Tub and Shower Silicone in Toronto & GTA
How often should tub and shower silicone be replaced in Toronto & GTA homes?
Every 3–5 years is a reasonable target in heavily used Toronto & GTA bathrooms. Signs of cracking, separation, or any visible mould within the sealant body mean it should be replaced regardless of age.
Can I use the shower or bath immediately after the silicone is applied?
No — 24 hours cure time before water contact is required. We advise on this when we schedule your Toronto & GTA visit so you can plan accordingly.
