Crawl Space Air Sealing

The framing above a crawl space is full of small gaps: where the wood sits on the foundation, where wires and pipes come through, around the plumbing and HVAC boots. Each one lets air, dust and sometimes pests pass between the crawl space and your home.

We air-seal crawl spaces across Nashville and Middle Tennessee, closing the rim joist, sill plate and penetrations with foam and sealant so the home above is more comfortable and the crawl space stays under control.

What you get

Done right, from the first walk-through

01

Rim joist and sill plate sealing

The most common source of air leaks is sealed with foam and caulk.

02

Wire and pipe penetrations

Holes cut through the subfloor are closed with the right sealant.

03

HVAC boot and duct gaps

Where ducts meet the floor, gaps are sealed so conditioned air stays inside.

04

Tidy, durable finish

Materials are chosen to stay in place and be safe in a crawl space environment.

The process

How your service comes together

  1. 1

    Find the leaks

    We look for light, dust trails and drafts at the rim and through the subfloor.

  2. 2

    Seal and insulate

    Gaps are closed with foam, sealant or backing, in the right material for each spot.

  3. 3

    Check and explain

    We re-check the sealed areas and tell you what changed.

FAQ

Common questions about air sealing

Will air sealing change how my house feels?

Many homeowners notice fewer drafts and steadier floor temperatures. Results vary with the home, and sealing works best along with insulation and moisture control.

Is spray foam safe in a crawl space?

Foam products made for building use are commonly used here. We follow product instructions and explain the choices we recommend for your space.

Do you seal around chimneys and flues?

Yes, using materials rated for the heat and clearances involved. We do not seal anything in a way that blocks required venting.
