RECENT CHELSEA PROJECT
We recently restored comfort to a 1900s farmhouse near Cavanaugh Lake that was costing the owners a fortune in propane heating. The original walls were empty, and the attic had thin, dirty batting. We performed a complete retrofit, injecting foam into the walls and sealing the roof deck. The result was a draft-free home that holds its temperature overnight, even during freezing spells.
Project Completed: Full insulation removal of debris followed by the installation of closed-cell spray foam in the basement rim joists and injection foam in the exterior walls.









Local insulation contractor
Chelsea’s unique blend of historic downtown architecture and sprawling rural properties presents distinct challenges. A home near the “Jiffy” factory faces different noise and vibration issues than a cottage on Pierce Lake. Our specialists understand these nuances. We use blower door tests to quantify air leakage, ensuring we target the specific areas—like knee walls or cantilevered floors—where your home is losing energy.
We also cater to Chelsea’s agricultural and commercial sectors. Pole barns and metal outbuildings are common here, but they are often prone to condensation and “sweating” in the winter. We apply commercial foam insulation that bonds directly to the metal, preventing moisture damage and creating a climate-controlled workspace for equipment or livestock.

FAQ
Absolutely. In fact, it is often the best choice for historic homes because injection foam can be added to walls without removing the plaster or drywall. It stabilizes the temperature and reduces the draftiness common in older balloon-framed structures.
Yes, typically any change to the thermal envelope requires a permit from the City of Chelsea or the local township. We handle all the paperwork and coordinate the inspection as part of our turnkey service.
Metal pole barns are notorious for condensation ("sweating") which can rain down on your equipment. Closed-cell spray foam bonds to the metal, stopping this condensation and adding significant structural rigidity to the building.
If the old material is wet, moldy, or filled with pest debris, insulation removal is essential. It allows us to air-seal the attic floor properly and ensures that your new insulation performs at its peak efficiency.
