Are you tired of skyrocketing heating bills during freezing Massachusetts winters or battling humidity inside your space during the summer? At Lamothe Spray Foam Insulation, we provide top-tier insulation solutions tailored specifically for homeowners and business owners in Sutton and the greater Worcester County area. Our team specializes in creating superior thermal envelopes that seal air leaks, reduce noise pollution, and drastically lower energy consumption. Whether you are retrofitting a historic farmhouse in West Sutton or managing a new construction project, our certified experts deliver precision and performance.
Creating a barrier between your living space and the harsh outdoor elements is essential for long-term structural integrity and personal comfort. In New England, where temperature fluctuations are extreme, standard insulation often falls short due to settling and gaps. We focus on comprehensive building science, ensuring that every nook and cranny from the attic rafters to the rim joists is properly sealed. This approach not only stabilizes indoor temperatures but also alleviates the strain on your HVAC system, extending its lifespan and reducing your carbon footprint.


Challenge: A homeowner in West Sutton was struggling with severe ice dams and a freezing second floor in their 1900s farmhouse.
Solution: We performed an attic cleanout and applied Closed-Cell Spray Foam to the roof deck, sealing air leaks responsible for heat loss.
Result: The ice dams were eliminated, and the homeowner reported a 30% reduction in heating fuel usage within the first winter.

Open-cell foam is lighter, less expensive, and excellent for sound dampening, but it is not moisture-resistant. Closed-cell foam is denser, provides a higher R-value per inch, adds structural strength, and acts as a vapor barrier, making it better suited for basements and exterior applications.
Yes, absolutely. Ice dams are often caused by warm air escaping into the attic and melting snow on the roof. By applying spray foam to the roof deck, we create an air seal that keeps the heat inside your living space, preventing the freeze-thaw cycle that creates dams.
Generally, yes. Leaving old, dirty, or compressed fiberglass can trap dust, allergens, and moisture behind the new foam. Removing it allows us to inspect the substrate for damage and ensures the spray foam adheres properly to the building structure for a perfect seal.
Dense-pack cellulose is superior to fiberglass batts for retrofitting existing walls because it is injected under pressure. This allows it to fill gaps around wires and pipes that fiberglass batts often miss, significantly reducing air infiltration and drafts.
Improving your home’s thermal envelope is one of the most effective ways to reduce energy costs. By sealing air leaks and increasing thermal resistance, your HVAC system runs less frequently, which can lead to heating and cooling savings of 20% to 50%, depending on the current state of your home.
