Basement & Crawlspace Insulation

Stop Heat Loss at the Source!

Your basement or crawlspace could be costing you money in wasted energy. Cold air enters and heat is lost through rim joists and uninsulated concrete foundation walls. Similarly, old fiberglass insulation in basement and crawlspace ceilings can also become damp, hold odors, and provide shelter and nesting material for mice.

At Wet Basement Solutions NH, we help homeowners address these problems at the source. We install rigid foam board insulation on foundation walls and in basement and crawlspace rim joists to help reduce heat loss, improve comfort, and create a more energy-efficient home. We also offer fiberglass insulation removal to help eliminate old, contaminated insulation from your basement or crawlspace.

Why Choose Foam Board Insulation?

Rigid foam board provides an effective way to insulate foundation walls and the areas where your home meets the foundation. When properly installed and sealed, it helps reduce heat transfer and air leakage in some of the most vulnerable areas of your home's building envelope. By addressing these areas, the quality and temperature of the environment is directly impacted.

Why Not Fiberglass Insulation?

Fiberglass insulation is commonly installed between floor joists above basements and crawlspaces. However, when insulation becomes damp, dirty, compressed, or contaminated, it may no longer perform as intended.

Fiberglass can retain moisture and odors, and the spaces around and within old insulation can provide mice with shelter and nesting material. Rodents may contaminate insulation with droppings and urine, leaving behind unpleasant odors and unsanitary conditions.

Rather than simply covering up the problem, we recommend addressing the areas where heat loss and air leakage occur. Our fiberglass insulation removal service helps homeowners eliminate old, unwanted insulation and take the next step toward a cleaner, more efficient basement or crawlspace.

Insulating the basement ceiling may reduce heat transfer between the basement and the floor above, but it does not address heat loss through the foundation walls or air leakage through rim joists.

Our approach focuses on improving insulation where it matters: along the foundation walls and around the perimeter of your home.By combining appropriate rigid foam board insulation with careful air sealing and the removal of old, contaminated fiberglass when needed, we help homeowners work toward a more comfortable, energy-efficient home.
