They were very professional. For example, they put down flooring protectors inside our home prior to doing the work. Because of the quality of the work we had them replace two failing sofits vents as well. They need to be onsite all day because of the scope of work, but made sure they cleaned up after themselves. Would definitely use them again. As part of the Mass save program Dolphin added new insulation in the attic, fill gaps, add weather strips in the basement door and did a complete set of air flow tests.

They were professional and responsive, and the job leader Dave was very knowledgeable. We would definitely use them again. Dolphin performed air leak tests, installed sealing and insulation and attic stair caps and other work recommended through a Mass Save energy audit.  

Business response:

[member name removed], Dave was recently BPI certified and is clearly showing off his new found knowledge. Thank you for taking the time to write about your experience with Dolphin. We are grateful to have worked with you! Thank you from Dave, Ryan, Seth and the rest of the Dolphin crew.

We used Dolphin Insulation via the Mass Saves program. They scheduled a date with us and came at a prompt time. The two contractors were very friendly and were very respectful of our home. They arrived and performed the work over the course of a few hours. They definitely did a GREAT job because this winter has been extremely cold, now our house stayed much warmer and our oil furnace runs far less than it did in previous warmer winters. I recommend them to everyone I know. I would definitely use them again. Added Insulation ... read more

On the day of the job it was extremely cold and temperature was below zero. The workers were very professional. they cover all the areas which needed work with cloth and also cover their shoes. There was no disruptions and inconvenience to us in any way. The lead technician was very thorough and took time to explain exactly what they were doing. We have a small dog and they were very understanding. They completed the job on time and as promised. We were extremely happy with Dolphin's employees and their professionalism. Thi... read more

They were very professional, arrived on time, and cleaned up well. The communication before and during was excellent. I would use them again. Dolphin did sealing and insulation work related to a Mass Save energy audit. 

Business response:

[member name removed], We are so grateful that you took the time to write about your experience with us before, during, and after the install. Glad we could make you happy throughout the process. We hope to see you again soon! Thank you from Chris and Jay and the rest of the Dolphins!

A wonderful experience from the booking through to the cleanup. Installing insulation isn't the cleanest process, but these guys did a fantastic job and I would recommend them to anyone looking make their house a little more energy efficient. The company also handled all of the rebate paperwork directly so all we ended up needing to pay was the difference. A great experience all around. Installed insulation in crawl spaces, knee walls, and attic. Installed door kits. 

Business response:

[member name removed[ We are humbled at your gratitude. Nice to hear you had a wonderful experience throughout the whole process. We hope to work with again! Thank you from Dave and Ryan and the rest of us here at Dolphin.

I have no complaints. I have some other issues that I have to work out before I can have them come back and actually do a job for me. I did pay them for the consult, which I thought was done very well. They spent a lot of time with me and went over everything with me very clearly. I had a good experience with that side of it but I just didn’t actually have any work done. I plan to have it done but I just can’t get it done right now. The delivered the report to me and the turnaround was less than a week. Everything went reall... read more

I used Mass Save program to determine if I need insulation around the house, and they told me I only need insulation from attic. (and the price is more than 1000, and because of the rebate from masssave, I only have to pay around 200). I found dolphin insulation from the list Mass Save gave me. They came here three times, first time they come they found out that the co level is too high and ask me to fix it otherwise it will be dangerous. Several vehicle and staff came, they are very friendly; Second time they come, they fou... read more
