Whether you're building new construction or upgrading an older home, our team delivers professional insulation solutions tailored to New England's demanding climate.
Woodstock experiences some of the widest temperature swings in the state, with freezing winters and humid summers pushing your HVAC system to its limits. Proper insulation is what keeps heated air inside during January and blocks the heat from creeping in during July. Our crew works with a range of materials and techniques to make sure every part of your building envelope is covered, from the attic down to the basement rim joists.





Your home's comfort shouldn't depend on outdated insulation that's settled, degraded, or was never installed correctly in the first place. Our team at Lamothe Insulation and Contracting evaluates your entire building envelope, identifies where energy is being wasted, and installs the right material for each area. We've worked in Woodstock long enough to understand the housing stock here, from 18th-century center-chimney colonials to new builds going up in the valley. If you're tired of drafty rooms, ice dams, or energy bills that keep climbing, give us a call at (508) 847-0119 or email [email protected] to schedule a free estimate.
A homeowner near Quasset Lake contacted us about ice dams forming along their roofline every winter and bedrooms that stayed cold no matter how high the thermostat went. Our team found that the attic had only a thin layer of settled fiberglass from the 1980s with significant air leakage around the chimney and recessed lights. We removed the old material, air-sealed all penetration points, and installed Closed-Cell Spray Foam Insulation on the rafters. The following winter, the homeowner reported no ice dams and noticeably even temperatures throughout the house.
