Work was done well. Post-test on seal of our house showed improvement. Pre-test house seal. Insulate exterior in the attic. Add seals on exterior doors. 

Business response:

(Member Name Removed) We hope you are feeling a warmer difference this winter and seeing smaller heating costs with the air sealing we completed at your home! Don't forget you can take advantage of the MassSave program every twelve months if there are any other improvements you would like completed in your attic or walls. Thank you from everyone here at Dolphin!

They were prompt, timely, and fixed the problem that developed. They showed up on time, the cleanup was great, and their price was lower. However, we got one problem with something that was broken when they arrived and they said they would repair it and they forgot. So we ended up having to take it to the company to have it repaired. They did insulation in our attic and rebuilt an attic cover. 

Business response:

(removed member name), Thank you for working with us to complete your insulation install. I'm glad we were able to fix the broken part but I do apologize it was forgotten about while on site the first time. Enjoy the rest of your winter a bit warmer inside with lower heating costs! Thank you from everyone here at Dolphin!

Ended up having 2 separate crews but all were professional, clean and knowledgeable. Worked efficiently and finished up the job earlier than anticipated. Added insulation to attic spaces. Vented bathroom fans to roof. Weatherstripped all doorways. Provided rigid foam insulation cover for whole house attic fan and attic hatches. 

Business response:

[member name], Thank you for taking the time to spread the word about how professional and knowledgeable our crew was. We take a lot of pride in the fact that our installers are certified in this field and spend much time studying new and better ways to tighten homes. Enjoy your much warmer and more energy efficient home! Thank you from Chris and Jay and everyone else here at Dolphin!

I have had some crummy luck with contractors lately, but this time I truly lucked out. These people love their craft, respect their craft, and take pride in their craft, which shows in all their work. When Bob came out to my house to see what we need to do for MassSave insulation project, he quickly discovered my attic was unholy dump of multiple generation of insulation piled on top of each other (try 50 years worth of insulation) mixed in with carcasses of dead squirrels, trash from roofers, vermin excrement etc. He was ad... read more

[member name removed], We really can't thank you enough for the kind words. All we can say is thank you, thank you. thank you!!! Much appreciation from everyone here at Dolphin!

I was very pleased with Dolphin's crew and the work that they did. They arrived on the day and time that was scheduled and completed all of the work in theplanned estimate of2 days. The crew was pleasant and personable and very conscientiousabout covering floors and furniture in the path to the working area as well as the working area itself. They did a great job of adequately covering all of these areas to prevent damage and to keep things clean. All tools and materials were collected and put away after the job was complete... read more

My 10 year old house couldn't hold the heat and always felt cold. It was insulated with R30 fiberglass insulation. I have cathedral ceilings in most of the areas and the rafters were 2x12s. I wanted to stop the "stack effect", because the fiberglass insulation seemed to be ineffective. Dolphin removed all the fiberglass with only a few holes in the plaster. The holes were needed because framing prevented them from getting access to the insulation. Most of the access was through knee walls, closets, and by taking off the fas... read more

Dolphin arrived on time and took care to cover all work areas with cloth and or plastic to catch debris. They performed the job in a timely manner and were able find a solution to an unexpected problem that arose. To make a long story short, Mass Save had recommended a vent be installed in an area that was not accessible. Dolphin was able to call Mass Save to change the work order to have the vent installed in a different, but approved, area. Despite all this, they finished on time and left the work areas cleaner than when... read more

Dolphins crew did an amazing job. Having our roof insulated has increased the warmth of our home and decreased heating and cooling bills. Highly recommend the work they do. Completely insulated entire roof
