Insulation removal
Old, wet, compressed or pest-damaged insulation vacuumed out and hauled away, so new insulation starts on a clean attic.

Crawlspace encapsulation
A vapor barrier over the ground, then closed cell spray foam over the liner, up the walls and into the rim joist. Your crawlspace becomes part of your home's building envelope, and ground moisture and humid air stay out.

How it works
Sealed from the ground to the rim joist
Pier-and-beam homes sit over a crawlspace with a dirt floor and vents open to the outside. Moisture from the ground and humid summer air collect under the house and work their way up through the floor.
Encapsulation brings the crawlspace inside your home's building envelope. A vapor barrier covers the ground with overlapped, taped seams and runs onto the foundation walls. Then we spray closed cell foam over the edge of the liner, up to the top of the walls and into the rim joist, and seal the vents.
The foam locks the liner to the wall so air and moisture can't slip in behind it, and it insulates and air seals the walls and rim joist in one step.
A sealed crawlspace still needs a way to stay dry. Building code calls for a dehumidifier, a small supply of conditioned air or a continuously running exhaust fan. We'll go over which one fits your home during the inspection.

What's included
What an encapsulation covers
Crawlspace inspection
We check for standing water, mold, pests and old insulation, and note anything that needs fixing first.
Cleanout
Debris and fallen or wet insulation are removed before the liner goes down.
Vapor barrier
A heavy liner over the ground, seams overlapped and taped, run onto the foundation walls.
Sealed vents
Foundation vents and other openings to the outside are closed and sealed.
Closed cell spray foam
Sprayed over the edge of the liner, up to the top of the foundation walls and into the rim joist. It seals the liner in place and insulates the walls.
Keeping it dry
Your quote lists how the sealed space stays dry: a dehumidifier, conditioned air or an exhaust fan.
How the job goes
From first call to finished
- 01
Inspect
We check for water, mold, pests, old insulation and open vents, and list anything that needs fixing first.
- 02
Clear and prep
Debris and old insulation come out so the liner goes down on a clean surface.
- 03
Seal and insulate
The liner goes down with taped seams, then closed cell foam goes over it, up the walls and into the rim joist. The vents are sealed.
- 04
Walk through
We show you the finished crawlspace and go over how it stays dry.
FAQ
Questions about crawlspace encapsulation
Don't see yours? Call (940) 245-6139 and ask us directly.
Does my house have a crawlspace?
If your home sits on piers and beams with a short space under the floor, yes. Most newer North Texas homes are built on a slab and don't have one.
Is encapsulation the same as a vapor barrier?
A plain vapor barrier is a sheet of plastic laid on the dirt. Encapsulation goes further. We spray closed cell foam over the liner, up the walls and into the rim joist, and seal the vents, so the crawlspace becomes part of your home's building envelope.
Why spray foam over the liner?
The foam seals the liner to the wall so air and moisture can't get in behind it. It also insulates and air seals the walls and rim joist, so the whole crawlspace is sealed from the ground up.
Do I still need crawlspace vents?
No. Once the crawlspace is sealed, the vents are closed off. Building code then requires a way to keep the space dry, such as a dehumidifier, a small supply of conditioned air or an exhaust fan.
How long does it take?
It depends on the size of the crawlspace and how much needs to be cleared out first. Your quote lists the schedule.
