It was time to breathe new life into this old rock foundation wall. The three primary objectives were to make the walls watertight, airtight and insulated. Starting with mortar, we sealed all the gaps in the wall. This was the first step needed to keep the basement dry. While it is not common to do mortar work before spray foam, we believed in this instance for a long-lasting job the mortar would help the spray foam stick better and actually “stitch” the stones in the wall together. And in some places along the wall above grade, you could look through to the outside. This obviously caused quite a bit of draft, robbing the basement of much needed warmth in the winter, and allowing warm and humid air easy access in the summer. Once the mortar work was complete, we sprayed the entire wall from top to bottom with approximately 2 inches of closed-cell spray foam. With an R-Value of about two before the spray foam, the rock wall now boasts an R-Value of 16. The cold earth on the outside of the wall will not penetrate the spray foam insulation, thereby allowing the ambient heat from the furnace to warm the otherwise unheated space. The homeowners can expect to see the equivalent in savings of 160 gallons of heating oil annually, not to mention a warmer, healthier and more comfortable home.

Infrared diagnostics, or thermal imaging, are an essential component of a thorough, whole-house energy audit. Analyzing each component of a home that is prone to air leakage, we are able to assess with our state-of-the-art infrared cameras where the most substantial air leaks are occurring, and determine where insulation in walls and attics has settled over time, was missing to begin with, or where it may have been improperly installed in the first place.
The insights given by a thermal scan during a home energy audit allow us to target the most cost-effective potential improvements to your home — from an energy standpoint, comfort standpoint, and cost standpoint — so your home upgrades achieve the greatest Return on Investment possible.
These infrared images, taken during a whole-house energy audit, are intended to shine some light on the infrared diagnostic process, as well as give you an idea of where energy waste most frequently occurs in typical North American homes.

We conduct thorough energy audits to uncover where your home is losing energy. Using tools like infrared cameras and blower door tests, we pinpoint inefficiencies that raise your utility bills. Our audits help homeowners prioritize upgrades with the best return on investment. You’ll get a clear picture of your home’s performance and where improvements can make the biggest difference. It’s the first step to creating a healthier, more efficient living environment.
Our team installs dense-pack cellulose insulation to improve your home’s thermal barrier. Cellulose is eco-friendly, made from recycled materials, and excellent at reducing air leaks and drafts. It’s especially effective in attics, walls, and other hard-to-reach areas. You’ll notice improved comfort and lower energy costs year-round. We take care to install it cleanly and precisely, maximizing its effectiveness.
Proper ventilation is essential for maintaining healthy indoor air. We install balanced systems like HRVs and ERVs that exchange stale indoor air with fresh, filtered outdoor air. These systems help control moisture, reduce allergens, and support energy efficiency. Our installations are neat, effective, and tailored to your home’s needs. Better air circulation means a more breathable, comfortable living space.
