Southwest Michigan's Trusted Spray Foam & Insulation Experts
Family-Owned & Operated • Free Estimates • Licensed & Insured • 50+ Years Combined Experience
A Local Insulation Company Built Around Honest Recommendations
We don’t believe in pushing one insulation product for every project. During your free on-site estimate, we evaluate the actual condition of your attic, exterior walls, crawlspace, rim joists, pole barn, garage, or commercial building.
That might mean spray foam, blown-in cellulose, fiberglass, air sealing, insulation removal, improved attic ventilation—or a combination of services. We’ll explain what we find, outline your options, and give you a clear estimate without high-pressure sales tactics.
Based in Mattawan, we proudly serve Kalamazoo, Portage, and nearby communities throughout Southwest Michigan.
"From beginning to end, Joe was communicative, honest, sincere and the best price around by hundreds of dollars. He also knew about a rebate I could apply for and had all the paperwork filled out for easy submission. Others that quoted the job never mentioned the rebate which saved me hundreds of more dollars!"
