3 Warning Signs to Look for in a Bathroom

Bathrooms are constantly exposed to water and humidity, so even a small opening or slow leak can eventually cause serious damage. Here are three warning signs to watch for:

1. Excessive condensation
Some condensation is normal after a hot shower, but moisture that regularly lingers on the walls, windows or glass can become a problem. Without proper ventilation, it could contribute to peeling paint, mildew and damage to surrounding materials.

2. Cracks or openings around the shower
Water can travel into small gaps through capillary action—the same process that allows a paper towel to absorb a droplet of water. Inspect the caulking, grout and seams around your shower for cracks or openings where condensed steam or water could be pulled behind the walls.

3. Moisture beneath the vanity
Use a flashlight to inspect the shut-off valves, supply lines and areas where pipes enter the wall. Look for dripping water, discoloration, staining or damp materials. A musty odor can also indicate hidden mold or mildew.

If you notice any of these warning signs, don’t wait for the damage to become visible elsewhere. Identifying and repairing the source of the damage early can help you prevent more extensive bathroom repairs.
