Clay that keeps the perimeter damp for a week at a time, under shallow crawl spaces with little air movement.
In Griffin the mold usually starts around the edges. Heavy Piedmont clay holds water against the foundation for a week or more after rain, so the perimeter of a crawl space stays damp even when the middle looks fine, and that is where growth begins.
The crawl spaces here are shallow, under mill-village homes and fifties ranches, with brick or block piers and open vents. Low clearance means poor air movement, and poor air movement means the humidity that comes off the damp perimeter has nowhere to go.
We treat the growth and take away what feeds it. Contaminated insulation and debris come out, the framing gets cleaned and treated, and then the ground gets a sealed cover with humidity control. On this clay we usually add perimeter drainage, because sealing a space where water still collects at the edges only moves the problem along.
The scope is fixed before we start on a Griffin 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!
