Half the homes in our area sit over a crawlspace, and almost nobody looks inside theirs. That's a shame, because the crawlspace is where West Tennessee's two favorite weapons — summer humidity and the occasional hard freeze — do their quietest, most expensive work. Twice a year, take a flashlight and give it ten minutes. Here's the checklist.
Water where water shouldn't be. Standing water or persistently damp ground after rain means drainage is pushing moisture under your house instead of away from it. That moisture becomes musty smells upstairs, cupped floors, and rot in the framing. Gutters, grading, and sometimes a sump pump are the fixes — all cheaper than a floor system.
The plastic on the ground matters. That sheet of plastic — the vapor barrier — is what keeps ground moisture out of your framing. If it's torn, shoved into corners, or missing, the dirt breathes into your house all summer. Recovering the ground is one of the least glamorous, highest-return fixes a crawlspace can get.
Insulation hanging like laundry. Fiberglass batts between the floor joists give up and sag once they've taken on moisture. Hanging insulation is a moisture report card with a bad grade — and it means cold floors in January.
Sweating ducts and open seams. In July, cold ducts in a humid crawlspace sweat like a glass of tea. Some of that is normal; ducts that are visibly wet, moldy, or blowing air out of open seams are heating and cooling the crawlspace on your bill. Duct sealing down there routinely pays for itself.
Pipes with their backs to the wall. Water lines running along the outer rim of the crawlspace are the first to freeze in a hard snap. Note where they are in June, and you'll know exactly what to protect in January — our frozen-pipes guide covers the how.
What you're smelling matters too. Musty is moisture. Sewage smell is a broken drain line under there, and that needs a call this week, not this season. Find something you don't like the look of?
