How to Check for Moisture Under Your House?

Moisture under your house can lead to a multitude of problems, including mold, mildew, and structural damage. Fortunately, there are a few simple steps you can take to check for moisture and take action if necessary.

Step 1: Visual Inspection

Use a flashlight to inspect your crawlspace or basement for any visible signs of water damage, such as:

• Wet or damp areas on the floor or walls
• Stains or discoloration on the wood
• Mold or mildew growth
• Rust on metal fixtures

Step 2: Moisture Meter

A moisture meter is a device that can measure the amount of moisture in the air or in materials. You can use a moisture meter to check the moisture levels in your crawlspace or basement.

• The ideal moisture level for a crawlspace or basement is between 30% and 50%.
• If the moisture level is higher than 50%, it could indicate a problem with moisture.

Step 3: Hygrometer

A hygrometer is a device that measures the relative humidity in the air. You can use a hygrometer to check the relative humidity in your crawlspace or basement.

• The ideal relative humidity for a crawlspace or basement is between 40% and 60%.
• If the relative humidity is higher than 60%, it could indicate a problem with moisture.

Step 4: Smell Test

A musty or moldy smell in your crawlspace or basement could indicate a moisture problem. Mold and mildew thrive in moist environments, so if you can smell them, it is likely that there is too much moisture in the air.

Taking Action

If you find any signs of moisture in your crawlspace or basement, it is important to take action to address the problem. You may need to:

• Repair any leaks or cracks in your foundation or walls
• Improve ventilation in your crawlspace or basement
• Install a dehumidifier to remove moisture from the air
• Call a professional for help
