Rotting Wood or Drywall

How to Check for Moisture Under My House?

Sustained moisture and humidity can cause your wooden foundation or drywall to rot, damaging the structure of your home. If you suspect moisture damage, it’s essential to check and address the issue promptly to prevent further deterioration.

Here’s a step-by-step guide to help you check for moisture under your house:

Visual Inspection

• Inspect the wood or drywall for signs of discoloration, warping, or swelling, which may indicate moisture absorption.
• Look for areas of mold or mildew growth, as they thrive in damp environments.
• Check for cracks, breaches, or holes in the foundation or walls, which could allow water to seep in.

Moisture Meter

• Use a moisture meter to measure the moisture content of the wood or drywall.
• Insert the meter’s probes into the material and check the reading. A reading above 15% typically indicates the presence of moisture.
• Take multiple readings in different locations to get an accurate assessment.

Thermal Imaging

• Consider hiring a professional to perform thermal imaging.
• This technique uses an infrared camera to detect temperature variations, which can indicate areas with high moisture levels.

Other Indicators

• Musty or earthy odors are often associated with moisture problems.
• Condensation on windows or walls can be a sign of excessive humidity.
• Increased energy bills may indicate that your heating system is working harder to dehumidify your home.

If you detect any signs of moisture damage, it’s crucial to contact a qualified professional for further assessment and repairs. Prompt action can prevent extensive damage and ensure the safety of your home.
