Check for water stains on walls or floors

Water stains on walls or floors may indicate moisture underneath your house, which, if left unchecked, can cause significant damage to your home’s foundation and structure. Several methods can be used to check for moisture under your house, including:

Visual Inspection:

• Look for water stains or discoloration on the walls and the floor in the basement or crawlspace.
• Inspect the foundation walls for cracks or gaps that could allow water to seep in.
• Check the floor for sagging or rotting, which could be a sign of water damage.

Using a Moisture Meter:

• Purchase a moisture meter from a hardware store or home improvement center.
• Insert the prongs of the moisture meter into the wall or floor and read the display.
• A high moisture reading indicates the presence of moisture.

Condensation Test:

• Place a piece of plastic wrap over a section of the wall or floor in the basement or crawlspace.
• Secure the plastic wrap with tape and leave it in place for 24 hours.
• If condensation forms on the inside of the plastic wrap, it indicates high moisture levels.

Other Signs of Moisture:

• Musty or moldy odors in the basement or crawlspace.
• Dampness to the touch on the walls or floor.
• Wood rot or decay.

If you find any evidence of moisture under your house, it’s important to contact a qualified professional for further inspection and to determine the source of the moisture. Prompt action can help prevent costly repairs and protect the structural integrity of your home.
