Professional Home Insulation Services That Save You Money & Increase Comfort

Your home's insulation is its first line of defense against Maine's extreme climate – from bitter sub-zero winters to humid 90-degree summers. At Heatmizer, we provide comprehensive insulation solutions that keep your home comfortable year-round while reducing your energy bills. Maine homes are as diverse as our weather: from 18th-century colonials with timber frames to mid-century ranches and modern energy-efficient builds.

 

Each construction era brings its own insulation challenges – whether it's preserving historic architectural details, addressing inadequate existing insulation, or optimizing newer builds for peak efficiency. Serving York County for over 10+ years, our certified experts understand these unique characteristics and will help you choose and install the right insulation solution for your home's specific needs.

Air Sealing

Air sealing is the foundation of every effective insulation project – think of it as zipping up your winter coat before heading into a Maine winter. Even the highest-quality insulation can't do its job if air is freely flowing through gaps and cracks in your home. Our certified technicians use advanced diagnostic tools like blower door testing and thermal imaging to identify these hidden air leaks, which commonly occur around windows, doors, electrical outlets, plumbing penetrations, and attic hatches. 
 

What We Seal:

  • Attic air leaks

  • Rim and band joists

  • Window and door frames

  • Pipe and wire penetrations

  • Basement and crawl space gaps

  • Other common air leak points
