Wet fiberglass hanging under the floor is doing nothing except holding water against your subfloor.
Almost every older Warner Robins home we open up has the same picture underneath. Fiberglass batts installed between the floor joists decades ago, now sagging, dark, and in places lying on the ground.
The cause is the same every time. The crawl space here stays humid because the ground below is damp and the vents bring in more moisture than they remove. Fiberglass absorbs that moisture, loses its loft, gets heavy, and falls. Wet fiberglass has almost no insulating value at all.
We take it out, deal with the moisture, and then insulate properly. In a sealed crawl space that means insulating the perimeter walls so the space stays within the conditioned envelope of the house, which works better here than trying to fight the humidity between the joists.
The scope is fixed before we start on a Warner Robins 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.
