Builder-grade batts in a humid crawl space have a short life. Most are past it by now.
Centerville homes from the eighties through the two thousands almost all got the same treatment underneath. Fiberglass batts between the joists, held with wire or staples, in a vented crawl space over bare ground.
That assembly has a predictable life in this climate. The batts absorb humidity, lose loft, sag, and eventually let go. Twenty or thirty years in, most of them are doing very little, and the rooms above show it as cold floors and uneven temperatures.
Replacement is straightforward on houses this age, because the framing is usually sound. We remove the failed material, seal the ground, and insulate the perimeter of a sealed crawl space so the assembly is not fighting humidity for the rest of its life.
Centerville homeowners get the same scope every time, priced in writing before a crew books the date.

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!
