Microbial Growth Removal in Crawl Space

Microbial damage is likely to develop in a crawl space when the area becomes wet. When a professional technician performs an inspection in a crawl space, we check for visible water leaks and invisible moisture particles in the air. We do this because it is unproductive to disinfect molds without addressing its primary cause—the mold is sure to come back if the source of moisture is still hanging around. 

Why Might a Home’s Crawl Space Have Mold?

If your home's crawl space has grading and drainage issues, mold can develop where the water collects under the house. Our SERVPRO technicians use pumps to extract water if it pools. If moisture is evaporating into the crawl space from the surrounding walls and the ground, we isolate the area. To isolate the area, we use a space liner to encapsulate the area. This enclosure acts as a vapor barrier and works well to prevent microbial growth when paired with a permanent dehumidifier in the crawl space. 

Basic science demonstrates that differences in temperature between surfaces and water particles cause condensation. The same is true for your crawl space. If the surrounding areas and the crawl space have differing temperatures, the water vapor condenses. We usually resolve condensation issues by using or installing a dehumidifier. The device assists in monitoring and controlling humidity to discourage conditions favorable to microbial growth. 

What If the Microbial Growth is Deep in the Insulation?

A professional in the microbial remediation industry will be able to examine the crawl space for signs of deeper mold infestation. However, it is not always easy to see. Sometimes, portions of enclosed spaces must be cut to see if microbial growth has infested your home’s insulation. When a professional certifies there is growth, then further microbial removal services can begin. SERVPRO has the tools and knowledge to remove and dispose of damaged insulation safely.

Not everything can be restored, but, as surprising as it sounds, it is possible to restore fiberglass insulation! It's also possible to remove surface mold, called mildew, from below supporting joists and beams and other hard surfaces. We also remove surface mold from porous items such as drywall—as long as the fungus has not penetrated too deeply with anchoring hyphae.
