Professional Insulation Contractors
From the charming historic homes in Old Village to the sprawling properties in Plymouth Township, local homeowners face a unique mix of drafts, ice dams, and high energy bills. Standard fiberglass and cellulose insulation often settle over time, leaving gaps that allow conditioned air to escape. Seal Tech Insulation provides advanced spray foam insulation and attic insulation solutions designed to seal your home’s envelope, improve comfort, and reduce utility costs by up to 50%.
The spray foam insulation Plymouth, MI residents trust for lasting efficiency. Whether you are near Kellogg Park or along Ann Arbor Road, our expert spray foam insulation contractors deliver professional air-sealing solutions that keep your home warm in winter and cool in summer.
RECENT PLYMOUTH PROJECT
A recent project on a 1920s craftsman home near Downtown Plymouth highlighted the need for modern efficiency in historic structures. The homeowners were struggling with freezing floors above their crawl space and significant street noise. We removed the damaged, rodent-infested fiberglass and applied a seamless foam barrier, instantly solving both issues without altering the home’s exterior character.
Project Completed: Comprehensive insulation removal followed by the installation of closed-cell spray foam in the crawl space and rim joists to block moisture and dampen sound.









Local insulation contractor
Plymouth homes range from century-old farmhouses to modern subdivisions near Hines Park. Each era of construction presents different challenges. Older homes often have “balloon framing” that acts as a chimney for heat loss, while newer builds may suffer from poorly sealed bonus rooms. Our specialists use blower door tests to pinpoint these invisible leaks, offering a targeted solution rather than a generic “top-up” of loose-fill insulation.
We also understand the needs of Plymouth’s vibrant business community. From boutiques in the downtown corridor to industrial spaces off Northville Road, we provide commercial foam insulation that adheres to steel, wood, and concrete. This adds structural rigidity and prevents condensation issues common in metal buildings.
