Inspect & Re-Caulk Tubs, Showers & Sinks

Remove old cracking caulk and reseal seams around tubs, showers, and sinks to prevent water damage, mold, and rot behind walls.

Supplies You'll Need

• Silicone caulk remover tool or utility knife
• New mildew-resistant silicone caulk (matching color)
• Caulk gun
• Rubbing alcohol or denatured alcohol
• Paper towels and painter's tape

Step-by-Step Instructions

1. Inspect all tub, shower, and sink seams for cracking, peeling, or moldy caulk.
2. Apply caulk remover along any old bead and let sit 15-30 minutes.
3. Scrape out the old residue with a utility knife or caulk removal tool.
4. Scrub the clean seam with rubbing alcohol and wipe dry with paper towels.
5. Apply blue painter's tape along both sides of the seam for a clean line.
6. Run a bead of fresh silicone caulk along the seam with a steady hand.
7. Smooth the bead with a wet finger or finishing tool, remove excess, and remove painter's tape before it dries.
