What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Inspect for visible damage

Begin by examining the grout and caulking in your bathroom for any visible signs of damage, such as cracks, discoloration, or mold.

2

Check for moisture issues

Use a moisture meter or your hand to check if there are any damp spots on surfaces around the grout and caulking that could indicate a leak.

3

Test the integrity of grout

Press gently on the grout lines. If they crumble or flake, it's time to consider re-grouting those areas.

4

Assess caulking adhesion

Carefully pull at the edges of the caulk to see if it comes away easily. If it does, you may need to remove and replace it.

5

Clean and prepare surfaces

Before any repairs, ensure surfaces are clean and dry. Use appropriate cleaning solutions to eliminate any mold or mildew.

6

Apply repairs and monitor

After performing necessary repairs, monitor the areas for a few weeks to ensure no new issues arise.
