We recently assisted a Cambridge homeowner dealing with high humidity and sagging floors due to moisture from the Choptank River. By performing a full crawlspace encapsulation and applying closed-cell spray foam to the rim joists, we reduced indoor humidity by 35% and stabilized the home's temperature, preventing future structural rot.

Closed-cell spray foam is an excellent vapor barrier. Unlike fiberglass, it does not absorb moisture, which prevents mold growth and protects your wood framing from the damp Eastern Shore climate.
Absolutely. Many pole barns in our area suffer from "sweating" or condensation. Spray foam eliminates the temperature differential between the metal skin and the interior air, stopping condensation and making the space usable in all seasons.
Open cell is great for soundproofing and attic ceilings where flexibility is needed. Closed cell is much denser, adds structural strength, and is waterproof, making it the preferred choice for crawlspaces or areas prone to coastal flooding.
Yes, we use "drill and fill" techniques with blown-in insulation or specialized injection methods to upgrade your home’s thermal barrier without the need for a major renovation.
Most residential projects in Cambridge can be completed in just one to two days. Once cured, the foam is completely inert and provides a permanent solution that will last for the lifetime of the structure.
