Moldy Caulking Removal & Replacement in Edmonton

Black or moldy caulking is a common problem in bathrooms and kitchens where moisture builds up over time.

Once mold grows into silicone sealant, it usually cannot be cleaned permanently. The best solution is to remove the old caulking completely and apply new mold-resistant silicone.

Refresh Works provides professional moldy caulking removal and replacement in Edmonton, restoring clean, waterproof seals around showers, bathtubs, sinks, backsplashes, and more.

Why Moldy Caulking Should Be Replaced

Mold growing in caulking isn’t just cosmetic. It often means moisture is trapped in the sealant and the waterproof seal may be failing.

Replacing moldy caulking helps:

• Improve bathroom and kitchen hygiene
• Prevent moisture damage behind fixtures
• Stop mold from spreading further
• Restore a clean and fresh appearance
• Maintain proper waterproof sealing

In many cases, cleaning products only temporarily remove surface mold, but the mold continues growing inside the silicone.

Replacing the caulking is the long-term solution.
