Sagging fiberglass does little in a humid crawl space. Wall insulation in a sealed space works much better.
Cold floors in January and a sticky feel in August have the same cause in many Fort Valley homes. The fiberglass batts pushed up between the joists years ago have soaked up humid air, lost their shape and dropped onto the dirt. What is left does almost nothing for comfort or energy use.
Fiberglass in an open, vented crawl space is a poor match for Middle Georgia. It holds moisture against the subfloor, it hides mold, and mice nest in it. You can usually spot it from the access door, hanging in loose sheets with dark stains along the paper face.
The better approach for a sealed space is to move insulation to the foundation walls. We take out the ruined batts, then fasten rigid foam board to the walls and rim joists and seal the seams. Combined with a liner and closed vents, that keeps the crawl space near the temperature of the house. You get a written estimate and photos.
Fort Valley homeowners get the same scope every time, priced in writing before a crew books the date.
