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

Identify the Source of Moisture

Start by inspecting your bathroom for any visible leaks or damp areas. Look closely at plumbing fixtures, walls, and ceilings to pinpoint where moisture might be entering.

2

Check the Sealant

Examine the caulk and grout around your bathtub, shower, and sink. If you notice cracks or missing sections, reapply waterproof sealant to prevent water from seeping behind walls.

3

Improve Ventilation

Ensure that your bathroom is adequately ventilated. Use exhaust fans and open windows to reduce humidity levels, which can lead to mold growth.

4

Inspect Your Flooring

Check for any signs of water pooling on the floor. Ensure that the flooring is properly sloped towards the drain to facilitate water flow.

5

Evaluate Drainage Systems

If you suspect groundwater issues, assess the drainage systems in and around your home. Ensure that gutters and downspouts are directing water away from the foundation.

Pro Tip
Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.
