Why Do Maryland Basements & Crawl Spaces Get Wet?

Flooded basement: Maryland has an annual precipitation that averages about 40 inches statewide, plenty to cause flooding and water damage. When flooding hits your area, your basement is most likely to be the prime target for water damage.

Other wet basement signs: There are many possible sources for pooling water, damp basement walls or flooring, and high humidity. These include: rusty basement windows, poor grading around the foundation, leaks through cracks in the foundation, saturated soils, simple plumbing failures, and poorly functioning drainage or sump pump systems. A basement already musty and damp is ill-prepared for the next bad rainstorm! Basement waterproofing can address the underlying issues, prevent future water damage and improve the indoor air quality.
