About Us

We're a small handful of builders and building science nerds, based in northern Vermont. We specialize in Building Envelope diagnostics and consulting, helping to safely and effectively air-seal and insulate buildings in the dynamic climate of the northeast US. We offer BPI certified home energy audits, residential & commercial blower door testing and leakage diagnostics, installation of air-sealing measures including AeroBarrier, and full test-out and documentation to ensure that your buildings meet all necessary code requirements for air-tightness. Available commercial envelope inspection protocols include ASTM E1827 and ASTM E779.

Our staff have over 60 years of combined experience constructing, diagnosing, and upgrading energy-efficient homes and buildings throughout New England; we are fully equipped to take care of your air-sealing requirements quickly and efficiently.
