Crawl Space Encapsulation & Insulation in Macon, GA

Crawl space encapsulation and insulation addresses one of the most common problems in Middle Georgia homes. Many houses here sit over vented crawl spaces on block walls or brick piers. Macon-Bibb's design criteria list summer humidity at 76.4%. When that air flows in through the vents and meets cooler surfaces under an air-conditioned house, moisture condenses. Batts get heavy and fall, wood stays damp, and musty air moves up into the house.

Encapsulation

We close the foundation vents, lay a heavy liner over the ground and up the walls, seal its seams and edges, and dry the space with a dehumidifier or a little conditioned air. HomeGuide lists encapsulation at $3 to $10 per square foot, about $3,000 to $15,000 for most homes.

Termite inspection access

Macon-Bibb rates termite risk as very heavy. Covering foundation walls with foam or a liner can hide termite tubes. We leave inspection strips where needed and coordinate with your pest control company so your termite protection stays in place. In some homes, insulating the floor above instead of the walls is the better plan.

Floor insulation

For crawl spaces that stay vented, insulation under the floor keeps the house comfortable. The Department of Energy suggests R-19 for floors in Zone 3. Closed-cell foam under the subfloor seals air and insulates in one step and holds up to humidity better than batts.

Water first

If water collects in the crawl space after storms, gutters, grading or drainage come before any sealing. Get a free estimate
