Crawlspace Encapsulation

Seal out moisture, mold, and pests for good.

An encapsulated crawlspace stays dry, protects your structure, and improves the air upstairs. We install heavy-duty vapor barriers, seal vents, and insulate walls for long-term performance.

What you get

Eliminates ground moisture and humidity

Bare-dirt crawlspaces continuously evaporate ground moisture into the air under your house. A sealed heavy-mil barrier cuts that off at the source, dropping crawlspace humidity from 70%+ down to normal interior levels.

Prevents mold, wood rot, and structural damage

Joists, subfloor, and beams sitting in a humid crawlspace eventually rot. Encapsulation protects the structural lumber holding your house up — far cheaper than replacing it later.

Cleaner air in the rooms above

Around 40% of the air in your first floor came up through the crawlspace. Sealing it means the air you breathe upstairs isn't pulling musty, moldy crawlspace air with it.

Adds real value at resale

Buyers and inspectors specifically look for encapsulated crawlspaces in California. It's one of the few below-grade investments that shows up clearly in inspection reports and appraisals.

Frequently asked

Do I need a dehumidifier?

In many California crawlspaces, no — a full encapsulation handles moisture on its own. We'll tell you if yours needs one.
