What Should I Do If My Basement Has Chronic Seeping Water?

Chronic seeping often comes from hydrostatic pressure pushing groundwater through concrete. Look for white efflorescence, damp spots, or paint bubbling. Check gutters and downspouts to see if water pools near the foundation.

You can test by observing during a rainstorm. Note where water appears and how long it stays. If the seepage is constant regardless of weather, the water table may be high. Keep a log of these observations to share with the pros.

• Inspect interior walls for cracks and stains
• Check exterior grading slopes away from the house
• Clean gutters and extend downspouts at least six feet
• Test your sump pump regularly
• Look for plumbing leaks that mimic seepage
• Note any musty odors that indicate mold growth

For minor cracks, use hydraulic cement or a masonry waterproofing product from a hardware store. Apply it when the surface is dry. However, sealing alone rarely stops chronic seepage because water always finds another path.

Interior sealants can help with damp walls, but they don't address the root cause. If you see large cracks or bowing walls, that indicates structural issues. Do not attempt to fix those yourself. Consult a structural engineer or a contractor who specializes in foundation repair.

If seepage is heavy, persistent, or accompanied by cracks that grow, you need professional help. The pros can perform a thorough inspection to identify the exact entry points and recommend solutions like interior drainage or exterior waterproofing.

They can also handle cleanup if you've had flooding or mold growth. In Detroit, where the climate is humid and wet, acting quickly can prevent bigger problems. Also, check your insurance policy to see what water damage coverage you have. Policies vary, and your insurer decides what is covered.

• Persistent dampness despite your efforts
• Visible mold or mildew growth
• Cracks that widen or shift
• Water pooling on the floor
• Sump pump running constantly
• Musty smell that won't go away
