They also noticed other issues that needed our attention and guided us in a decision for what needed to be done. When the project was completed, they did a thorough cleaning of everything. They left the place spotless. Overall, we are extremely happy with the job they did. I would recommend them! Thanks for the great work. read less

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. read less

He showed up at the time we scheduled, asked all the right questions and gave me a state of the art solution to a problem I could never seem to fix. I thought it was just an older home and it would always be leaky. It was about double the cost I expected to spend but when he explained all the benefits and ROI it was a no brainer. We scheduled a few days for the install and the crew was friendly, protective of my home, and worked diligently. They cleaned up after and everything looked great. It’s been a year now and compared to last year I have saved $4,500 and according to my calculations this job will pay for itself in 4 years saving around $400/month. The house is warmer, quieter, and the heat is turning on much less giving our hvac a break. Couldn’t be happier. Thanks for a great job! read less

Getting three quotes, Dolphin's Chris was the most professional, seemed to know what he was talking about the most, and gave us a comfortable feeling. Add in that their pricing was equal to or better than the others, depending on which part of the house, and it was a done deal. We had the attic completely re-insulated, throwing out all the old fiberglass, air sealing everything and new 18" of cellulose, as the first stage. Dolphin showed up when promised, took less time than I expected, and did what seems to me to be an excellent job, worked cleanly, and cleaned up thoroughly every night and end of job. I will use them for the next insulation project. read less

I came to know them while managing a home rebuild project for the Schultz Family in Stow. The project was a donation based effort to replace a home that was overcome by toxic mold while the family was attending to a devastating health situation involving their young son. The house could not be salvaged and had to be torn down. Chris and Amanda stepped up immediately upon hearing of the situation and (working with their vendor partners) offered to donate all the labor and materials required to insulate the new home. It was especially important to the Alphin's that the house be built in a way that the mold situation could never happen again. In addition to the generous offer, Chris brought a level of insulation expertise that is unmatched in my 35 years in construction. In fact, Chris knew so much about his industry and the cutting edge materials available, I called on a trusted building envelope consultant, Neil Rouleau of Building Restoration Services, to help me sort it all out. Neil confirmed that this was a state of the art and extremely generous offer. The praise doesn't end there. In my years in the industry, I've come across a lot of people who talk a good game but fail in the execution. Nothing could be further from the truth here. The installation crews were experienced, hardworking, and great to work with. Given the donated nature of the project we had times when the work flow had to be rearranged. They reacted like true professionals and did whatever it took to get the job done. And they left the jobsite cleaner than when they arrived! Again, I can't say enough about how much I enjoyed working with Dolphin Insulation, and what quality people they are to do what they did. Look forward to working with them again. read less

Their team installed excellent weather stripping on doors and sealed attic drop-down stairs. I was so impressed I called them for a home energy audit. I found out they have more expertise including energy efficient remodeling, attic insulation enhancements, and even basement and slab construction insulation. A few years later and several projects completed and our home is more comfortable year round. The whole team at Dolphin is excellent. They know the pitfalls of poor quality construction and how to remedy it to make your home more efficient. read less

By the time Dolphin arrived on the day after Labor Day, we were shell shocked from contractors and having strangers running around our house turned upside down to accommodate the work that needed to be done. We were completely impressed with David, the site foreman. He was affable and easy to talk to. He kept us up to date on all activity and really eased our concerns about every aspect of the work. His crew was just outstanding and he managed them with respect and precision. I have witnessed work crews before, but yours was a cut above! Not only were they respectful of us and our home, but they exhibited respect for each other rarely seen in blue collar circles. They were in constant motion performing their specific tasks like a well oiled machine! We just couldn’t have been more impressed and pleased. An unexpected bonus was that there is less outside noise penetrating into the house. We have an active street and our neighbors are busy from morning to nightfall and beyond. I used to be able to hear conversations on the street, but after your crew was done, our house is much quieter. And the icing on the cake was when the Mass Save inspector came out to inspect your work. I followed him around and he was also impressed with the work performed and stated that our contractor "had done an excellent job!” He asked who did the work and I told him, “Dolphin". He said that “they always do excellent work!” Boy, was I glad to hear that! Dolphin Insulation exceeded our expectations and left us with a warm feeling and a warmer (and cooler) home! We just wanted to say, “Thank you, from the bottom of our hearts!” read less
