Professional Insulation Contractors in Howell
From the historic Victorian homes lining Grand River Avenue to the expansive rural properties in Marion Township, Howell homeowners face distinct climate challenges. The open landscape along the I-96 corridor brings high winds and drifting snow that can overwhelm standard fiberglass and cellulose insulation. Seal Tech Insulation provides advanced spray foam insulation and attic insulation services designed to seal your home’s envelope, eliminate cold drafts, and reduce heating and cooling costs by up to 50%.
The spray foam insulation Howell, MI residents trust for year-round efficiency. Whether you need to insulate a historic home near Thompson Lake or want to stop condensation in an agricultural building in Howell Township, our spray foam creates a stable climate that protects your livestock, equipment, and family from Michigan’s extreme seasonal shifts.”
RECENT HOWELL PROJECT
A recent renovation near the Howell Opera House highlighted the need for modern efficiency in historic structures. The homeowners were struggling with freezing pipes and uneven heating. We identified that the original balloon framing was allowing air to rush from the basement to the attic. We sealed these bypasses and insulated the exterior walls, preserving the home’s character while drastically improving its performance.
Project Completed: Comprehensive insulation removal of debris followed by the installation of injection foam in the walls and closed cell spray foam in the rim joists to stop the “stack effect.”









Local insulation contractor
Howell’s diverse housing stock requires a tailored approach. A 1900s farmhouse in Howell Township has different needs than a modern two-story in a new subdivision. Our specialists use blower door tests to pinpoint the invisible leaks that are unique to your property. We don’t just add more material; we engineer a solution that targets the root cause of your energy loss, whether it’s a drafty knee wall or an unsealed crawl space.
We also support Howell’s vibrant commercial and agricultural sectors. From pole barns used for farming to commercial warehouses off Highland Road, we provide commercial foam insulation that bonds to metal and wood. This prevents condensation issues common in agricultural buildings and creates a stable climate for equipment and livestock.
