Damp ground in the low folds keeps pushing the number up. The unit is what pushes it back.
A house in one of the low folds around Sunny Side sits over ground that stays damp for long stretches, so even a well sealed crawl space here carries a residual moisture load through most of the year.
A dehumidifier is what keeps that load from turning into a problem. Held in the fifties, the space stops growing anything and the framing stays stable. Left to drift into the seventies, everything that sealing was meant to prevent starts again.
We size from the measured footprint and humidity, install where air circulates, and drain the condensate by gravity since the terrain here provides fall. Where runoff is arriving from uphill we deal with that too, because reducing the water reaching the house lowers the load the unit has to carry.
The scope is fixed before we start on a Sunny Side 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!
Thank you Trench Guys for repairing our foundation. John gave our home a thorough inspection and explained the process so we knew exactly what the problem was and our options. They worked hard and were friendly and knowledgeable.
We run the same crews across Spalding County and the rest of Middle Georgia.
