Water sources

Water sources in your house can be great sources for mold growth and contamination. A good general rule – if you smell mold, look for it because it is probably present.

Bathrooms
Leaks and excessive moisture are the main problems that lead to mold growth, biological contamination and possible wood damage in your home.

Sinks
Sink faucets and valves often are sources for leaks. Water can leak to the vanity, rotting the wood. Water falling behind the vanity along the wall because of improper installation or worn caulking can lead to undetected rot and mold growth.

Toilets
Check for water leaks and excessive condensation. If the toilet leaks or tips from side to side, have it repaired. If the wax ring on which toilet sits is broken, you may see a water stain on the ceiling below. Sewer gas may leak into the bathroom, causing an unpleasant odor and provoking your symptoms.

Showers and Tubs
Water leaking out of the shower onto the floor can get under tiles. As the water accumulates, the floors and subfloor can rot and become a source for mold growth.

Here are some simple tips to keep water sources from becoming a problem:

Keep your shower curtain in the tub.
Replace the shower curtain or its liner when it begins to smell or becomes discolored.
Make sure the shower door railings are properly caulked and water tight.
Periodically clean the undersurface of shower doors with a fungicidal bleach solution.

Dry out your shower after bathing. Open shower curtains or doors, turn on an exhaust fan, open a window and/or keep the bathroom door open.
