A homeowner in New Carrollton contacted us about persistent cold floors and rising heating costs during winter. Our team inspected the property and found an uninsulated crawlspace and an attic with deteriorating fiberglass batts. We installed Crawlspace Encapsulation and Closed-Cell Spray Foam in the attic, sealing air leaks and adding a continuous thermal barrier. Within the first billing cycle, the homeowner reported a noticeable drop in energy use and warmer floors throughout the house.

Spray foam insulation can last 80 years or more when installed correctly, meaning most homeowners never need to replace it.
Spray foam works well in both new and existing homes, and our team can retrofit it into attics, crawlspaces, and walls with minimal disruption.
Open cell is lighter and more flexible, ideal for sound control and filling large cavities, while closed cell is denser and adds structural strength along with a moisture barrier.
