Shallow subdivision crawl spaces with bare ground under them. Mold gets established quietly.
Centerville homes from the eighties through the two thousands almost all have the same crawl space design. Shallow clearance, block perimeter walls, open vents, and bare earth on the floor. That was standard practice, and it creates conditions mold does well in.
The soil profile keeps the ground damp. Sandy topsoil over dense clay means water enters easily and stops, so the upper soil holds moisture much of the year. In a shallow crawl space that damp ground is close enough to the subfloor to keep it in the range where mold grows.
Because these houses are relatively young, the mold is often ahead of any structural damage, which makes this the cheap moment to deal with it. We treat and clean the affected framing, take out anything contaminated, then seal the ground and control the humidity so it does not come back.
The scope is fixed before we start on a Centerville home, so nothing gets added once the crew is underneath.

Trench Guys came to my home and corrected a sagging kitchen floor. They did a great job and guarantee their work for 10 years! I absolutely will be calling them anytime I need help.
I don't usually write reviews but John and his crew are absolutely awesome. They did my crawl space encapsulation. I got other quotes - don't waste your time with the other guys. Outstanding service at an incredible price!
