Welcome to Frontier Energy Solutions, Inc.

"Delivering Sustainable Solutions to Cape Cod and the Islands"

Founded in 2007, Frontier Energy Solutions is a locally-based company with offices in Brewster and Harwich Massachusetts.  Frontier Energy Solutions serves Cape Cod and the Islands, providing insulation services, energy consultations, assessments, building performance enhancements and weatherization installations to residential and commercial properties.


Our vision is based upon the premise that energy efficiency and renewable energy systems reduce your dependancy on fossil fuels, your carbon footprint, and best of all, your monthly utility bills.  Unlike other insulation companies, we look at every house from a whole house building science perspective.  Our motto is energy efficiency first!


Using a series of diagnostic tools, we diagnose your home's problematic areas and offer you solid solutions driven by three requirements: the quickest return on your investment, the greatest energy savings and increasing the overall comfort of your home or building.


Frontier Energy Solutions carries BPI certifications as Building Analyst and Building Envelope Professionals.  We carry a Massachusetts Construction Supervisor license as well as a Home Improvement Contractor license.  We also carry a photovoltaic system installer certification and we are an EPA registered Lead Safe Firm.
