The active ingredient in bleach, sodium hypochlorite, usually comprises only 3-5% of the solution and may not penetrate deeply enough to eliminate crawl space mold at its core.
Standard bleach solutions, predominantly water-based (typically 95-97%), can seep into porous surfaces like unfinished crawl space wood materials. This moisture may inadvertently create an environment conducive to fungal growth beneath the surface.
Similar limitations apply to household antimicrobial agents, like white vinegar and hydrogen peroxide, which cannot entirely eliminate mold and only address surface-level contamination.
How to Remove Mold in a Crawl Space DIY
DIY mold removal is often more accessible than hiring a professional. However, we do not recommend at-home solutions for the following reasons:
Safety Risks: Crawl spaces pose safety risks due to the small, dark, and confined area.
Potential Pest Infestation: Unkept crawl spaces often harbor pests and rodents, potentially causing health hazards.
Chemical Exposure: Inhaling bleach in an enclosed crawl space area is dangerous.
Hiring a mold remediation expert is the safest solution for removing crawl space mold.

I used FSS because it was listed in the Best Pick Reports. My foundation repair began on Wednesday, October 23rd and was completed on Thursday, October 24th. My repair crew consisted of Earle C, David H, Robert T, and Moses I. These young men arrived at the time they said that they would or earlier. Earle was the team lead. Earle took the time to answer my questions, was knowledgeable, and provided reassurance. The construction team were very respectful of my property, and were courteous.

Chris came out to do the initial inspection and helped me to develop a plan to stabilize the house. It was a two day job with a four man crew; Robert Torres, Michael Luera, Stafford Cooper, and Mark Lopez worked up a sweat to support and lift my home. They did a great job with clean up and were very polite on site.
