Our company has found that by performing a combination of HEPA vacuuming and HEPA sanding, typically yields some of the best results when conducting mold remediation in a crawlspace. 

Our HEPA sanding process is performed with an orbital sander that is connected to a HEPA vacuum, so that the dislodged mold/fungal spores can be more readily captured. We also wire-brush hard to reach areas, where HEPA sanding is not possible. 

 

Additionally, we also utilize a combination of hand wiping crawlspace surfaces with a low-VOC antimicrobial solution, as well as spraying the crawlspace wood surfaces with a concentrated hydrogen peroxide cleaning solution (zero VOC). Concentrated hydrogen peroxide is a safe and environmentally friendly product to use in the crawlspace, due to the fact that it breaks down into oxygen and water after it has been sprayed.
