Our story
Sixty-plus years of experience, serving homeowners since 2007.
McMahon brings sixty-plus years of hands-on building-trade experience to every project, long before weatherization and Mass Save became household terms.
We opened McMahon Insulation in 2007 to do honest insulation and weatherization work for our neighbors across Eastern Ma, South Shore, South Coast, Cape Cod & the Islands.
Today we work as Mass Save participating contractors and BPI-certified weatherization pros. Whether it’s a draft you can’t track down, an attic that’s costing you all winter, or a Mass Save report you’d like a second opinion on, we’re a phone call away.
60+ Years Experience · Since 2007 · BPI-Certified · Licensed & Insured
