Common Crawl Space Problem Signs  

When it comes to crawl space problems, it’s best to recognize them quickly and call the experts at Tar Heel Basement Systems for a speedy repair. Left untreated, your family’s health and the structural integrity of your home may be at risk. From standing water to sagging floors, knowing you have a problem is the first step.  

crawl space flooding

Standing Water

Groundwater puddles are, unfortunately, more common than North Carolina homeowners would like to think. Since your crawl space commonly has a dirt floor, any water absorbed after rain will likely result in puddles beneath your home. This water causes numerous problems for your crawl space and needs to be pumped out as quickly as possible using a reliable sump pump.  

Mold on crawl space joists

Crawl Space Mold

Your dark, damp crawl space is the perfect environment for mold growth. Mold is everywhere but thrives and grows in areas where humidity levels are high. The CDC recommends humidity levels should be kept between 30 and 50 percent–all day long. In a crawl space, this means a proper waterproofing system, crawl space encapsulation, and most likely a self-draining, energy-efficient dehumidifier.

Crawl Space Pests

In addition to mold, pests find a dark, moist crawl space an ideal location. It’s not uncommon for Wilmington or Winston-Salem homeowners to notice increased pests in their living areas before tracking the problem to their crawl spaces. Sealing your crawl space through encapsulation and controlling humidity levels is the best way to stop pests and make the area less desirable for infestations.  

crawl space condensation


Condensation, or the process when water vapor becomes droplets on a cold surface, can be just as damaging in a crawl space than standing water. In North Carolina, where the summer days are hot and humid, but temperatures dip in the evening, condensation is a common problem. The EPA recommends adding insulation to areas with condensation problems. This can be done by encapsulating your crawl space and adding a rigid foam insulation board to crawl space walls, not the pink, big-box store insulation that causes more harm than good.
