Testimonials

Melvyn from Plymouth
Your technicians made a scheduled appointment at our house this past Tuesday to complete a work order. We wish to commend you for hiring such competent individuals. They were knowledgeable, personable, task-oriented and totally honest and reliable. We were impressed by their work ethic, their excellent customer service and the time they took to explain what they were doing and clearly answering questions and presenting their data in a direct, non-confusing manner. They worked through without taking a lunch break, related well with each other as well as with us and were scrupulous at leaving their work space sparkling clean.

I wanted to tell you how great a job the installers did putting in my attic insulation. My AC has been out for a few days and the insulation has kept the temperature down. Usually a second story would be boiling, but the men did such a great job that I was able to stay here. 
Wendy from Wareham
I would like to express how grateful to each and everyone of you for helping make my house warmer for the winter months, its because of you I was able to have insulation and seal areas of my home that wouldn't get done. Thank you Jonathan for coming out to seal my front door that meant so much! Again thank you for your excellent quality work!

After conducting a thorough and (extremely) informative energy audit, Efficient Buildings assessed that the most cost-effective improvements I could make would be some simple air sealing and improved attic insulation -- they didn't try to sell any expensive windows or talk me into having work done that didn't need to be done.  After making the recommended improvements (which were quick and affordable), I can already feel the difference in my home.  It's more comfortable, less drafty, and although it's still early to say for certain, I'm almost certain my heating bills will be seeing a significant decrease.  I highly recommend Efficient Buildings for any type of remodeling-related work,… (read more)
James Chase, Bridgewater
I hired Efficient Buildings to do some insulation work at my house, as I had heard that attic insulation was one of the best ways to cut heating costs, and Efficient Buildings came highly recommended from a friend. After assessing the space they concluded we'd be better served to start with air sealing - a relatively quick and easy job, and much easier to add before the insulation goes in.  I dug into some research and concluded they were right. They got the job done meticulously and quickly, with a small, extremely courteous and professional crew, and the effects are immediately apparent.  Efficient Buildings is a fantastic contractor… (read more)
