Crawl Spaces
Crawl Space Encapsulation
Fully encapsulating a crawl space — sealing it and insulating it — is the most complete way to solve crawl space problems for good, rather than treating symptoms one at a time.
Encapsulation means sealing all outside vents, installing a high-performance vapor barrier across every exposed wall and floor surface at or below grade, insulating the walls and rim joist, and conditioning the air inside the space. Done as a complete system, it does more than dry out the crawl space — it improves indoor air quality and can lower energy usage, a benefit backed by research from Advanced Energy.
Why the Liner System Matters
A zero-perm liner system that also insulates and reflects heat delivers the most benefit. With a proper floor and wall liner in place, the crawl space is well insulated, sealed against moisture, and protected from mold growth. A zero-perm liner also weatherizes the space and helps on your energy bills, since outside air can no longer leak into the home through the crawl space.
Why Sealing the Crawl Space Protects Your Air Quality
The EPA lists indoor air pollution as one of the top five environmental risks to your health, and a damp crawl space is a significant contributor. Because of what's called the stack effect, a large share of the air you breathe inside your home actually starts underneath it and travels up through the structure — warm air rises and escapes through leaks higher in the house, pulling in air from the crawl space to replace it. When that crawl space is damp, it's carrying dust, mold spores, allergens, and soil gases with it into your living space.

Frequently Asked Questions
A vapor barrier covers the floor and is one component of encapsulation. Full encapsulation goes further — it seals the outside vents, covers the walls as well as the floor, adds insulation to the walls and rim joist, and conditions the air, turning the crawl space into a sealed, controlled part of the building envelope.

“Rob and his crew are super. I had a very big project to renovate a 130-year old farmhouse. They worked diligently to put in new piers, new girders, and new joists. Then they also help to fix some frames and add subfloor. This allowed me to move on. Really enjoyed working with Rob.”

“Very professional! They carried out their task while going the extra mile. It was obvious to me that quality is of great importance. They left it better than they found it. I would recommend them to my greatest of friends and family.”

“After having some minor flooding issues, we contacted Triangle Reconstruction and they were amazing in their ability to identify the issues and the best way to address it. What was most impressive was the team that came out and did the work. They were probably the most professional and organized crew we've ever seen work on our house. Brian, our rep, and Rob, the owner, regularly checked in on their work and kept us updated on the progress. I hope I never have to deal with flooding issues again, but if I do, I'll call Triangle Reconstruction again.”
