Dolphin Insulation was amazing. We had Mass Save do an energy assessment then we chose Dolphin as the contractor. The Dolphin crew was professional, friendly, prompt, and cleaned up each day. Our project ended up being larger than we had planned, but that was due to Dolphin recommending removal of our old insulation that had mold and mice urine/feces all over it. They gave us the benefits of removal and it was a no brainer. I wish the Mass Save consultant would have suggested removal versus just adding new insulation on top ... read more

Dolphin's salesman was excellent, answered all questions and explained suggested insulation for various parts of house and possible priorities. We decided to have attic done first, seemed to be best return on investment, and installers were always on time, worked as cleanly as one can with that kind of job, finished job in good time.

Mass save worked well for us. I do understand we saved a ton of money. The work was great and I am appreciative of the difference it has made in our home. They were punctual and even stayed passed the 4:00p quoted time frame to complete the job. However, we were told that we would need additional work and three times was told by the foreman of the job it would be about $25-$30 extra. Of course we agreed! Why wouldn't we when every thing was going great! We don't know how this works and assumed they did. Today I received a bi... read more

The job went well, they were punctual, very courteous and professional. The workers Dave and Tom were very friendly and very respectful of the property. Any questions I had were addressed and answered. They were very neat and cleaned up all areas. Insulated attic space that had to be done thru access thru the roof, old insulation was removed and attic space was filled to capacity. Basement walls had insulation removed and bibbing installed to contain the blown in insulation

Dolphin had been highly recommended by a colleague who had done extensive renovations. They did not disappoint for our much smaller job. The price was surprisingly reasonable, and the crew was professional and nice to work with. When they were stuck in traffic one morning, they called to say they would be a little late. The job was done on time, and they did not leave a trace. Also, there was a spot we had not identified that penetrated the envelope. They seal and insulated it without additional cost. Working with Dolphin wa... read more

It went well. They came on time and worked hard. It took longer than expected as the men needed more supplies but in the end they did a geat job. It looks very nice. We had our basement ceiling insulated.

I had my attic air sealed, added additional blown in insulation and had my bathroom exhaust fan vented properly through the roof. Dave and crew from Dolphin were on time and did a quick quality job. They were also very meticulous about clean up which was great too. Very good company to work with if you require any insulation work. Attic air sealing, insulation, and bathroom fan venting

From first call to project completion, Dolphin Insulation was a pleasure to work with. We are building a fairly complex custom home that presented some challenges in insulating and air-sealing. The crew at Dolphin dedicated to helping us problem solve and arrive at the best finished product. As a general contractor, I rely on my trade partners to execute our projects correctly, on time and on budget. Dolphin's flexibility and expertise was a great help on all fronts. I plan to work with them again on future projects. Insulat... read more

Cannot recommend Dolphin enough. I had contacted 5 insulation contractors to come out and look at my 100+ yr old home with no insulation. The walls are original plaster and lathe and hollow. Only Dolphin came out to visit and gave a comprehensive review and quote. We first had only the basement rim joist insulated. 2 yrs later we decided to take on the full job of insulating all of the walls. Dolphin came out again and revised the quote and looked over the job. The crew arrived in October and insulated the walls over 3 days.... read more
