How to Check for Moisture Under My House?

Moisture infiltration into your home’s structure can cause severe damage if left unattended. Conducting regular checks is crucial to identify and address potential issues promptly before they escalate into costly repairs.

Exterior Wall Inspection

• Examine the siding for any cracks, gaps, or loose panels.
• Check window frames and doors for any gaps or missing caulk.
• Inspect pipes, vents, and other penetrations for any visible leaks or gaps.

Roof Inspection

• Look for any missing or damaged shingles, which can create entry points for moisture.
• Inspect the gutters and downspouts for clogs or leaks, ensuring proper water drainage away from the house.
• Check the flashing around chimneys and vents for any gaps or damage.

Foundation Inspection

• Look for any cracks, gaps, or crumbling in the foundation.
• Check for efflorescence (white or crystalline deposits) on the foundation walls, indicating moisture penetration.
• Inspect the soil around the foundation for any signs of water accumulation or grading issues.

Other Areas to Check

• Inspect the crawlspace or basement for signs of dampness or standing water.
• Check the attic for any signs of roof leaks or condensation.
• Look for any mold or mildew growth on the exterior walls, siding, or roof, indicating moisture buildup.

Additional Tips

• Conduct regular gutter and downspout cleanings to prevent clogs.
• Ensure proper grading around the foundation for effective water drainage.
• Seal any gaps or cracks around openings, pipes, vents, and windows.
• Consider installing a vapor barrier in the crawlspace or basement to prevent moisture penetration.
• If you suspect moisture damage, contact a qualified professional for further assessment and repairs.

By diligently checking your home’s exterior for signs of moisture, you can proactively identify and address potential issues, helping protect your property from costly repairs and health hazards.
