Our Team

Skilled. Start to finish.

Penobscot Home Performance was founded by Matthew Damon and Paul Shepherd, certified energy advisors and experienced general contractors. We’ve been invited in to take a good look, to advise, and eventually to help take good care of what is often the largest investment people make in their lifetimes.

Our team has been trusted to help improve the efficiency and value of homes of all ages, shapes and sizes in the greater Bangor and upper Midcoast areas since 2008. Our reach extends to Downeast and MDI as well. We are able to go where we’re needed. From Belfast to Bar Harbor and far inland, we service the region, bringing nearly 20 years of knowledge and experience to each home.

All about results

Our skill in assessing, explaining and completing projects that dramatically improve the comfort and energy performance of homes is unmatched in Penobscot County and beyond. We also excel at servicing light commercial spaces and multi-family homes. We’re proud of the work we do and are inspired by the homeowners we meet who make the decision to plan and put a little more into the place they call home. Read what our customers have to say about our work.

My house was drafty before Penobscot Home Performance insulated my walls and basement. In my first year of living in this house I probably spent nearly $1,500 on fuel to heat my home. Now I’m down to around $900 and I can run the heat at 68 degrees and be comfortable. I’ve been thoroughly amazed at how much it’s improved. —Barbra S., Orono
Just thought I'd give you an update on Oil Consumption in our 1843 house in Orono—we went from averaging 956 gallons/year to heat the house in the first 3 years we owned it, down to 613 gallons last year after the air-sealing and insulation work you all did, and we're on track to match that this year. —James S., Orono
