Invest in your home

A wet crawl space or basement can damage your home. Excessive water intrusion can cause damage to your home's foundation, as well as create high levels of humidity. Humidity leads to mold, pests, and poor air quality in the home. Did you know that 60% of the air on the 1st floor of a home comes from the crawl space or basement? If wet conditions persist in these areas, the air quality in the home dramatically decreases. Coastal Basement Waterproofing specializes in correcting these problems. We will leave your home with a clean and usable crawl space or basement that is protected against the toxins that transmit into the atmosphere. Value you can see and breathe.
