TEMP
After home is waterproofed … and has at least tar paper on roof and windows in place we would:
1. Clean entire crawl floor of all construction rubble and roots.
2. Place 6 mil clear poly on entire crawl floor with tape/insulation stays to secure placement
3. Place at least 1 fan if not 2 to reduce chance of mold.
-If crawl is very moist we will put a dehumidifier or two for a week or more to dry out crawl to limit any mold growth.

FINISH

1. If crawl has lite mold: team will hand wipe with sponge and mold remediation Benefact solution.
2. If crawl has heavy mold we will power spray with Benefact solution entire crawl back to new.
