Dolphin Insulation

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 adamant that needed to be removed before any sealing and insulation work is done.
At first I wasn’t sure about that, but boy am I glad I listened to him and had it cleaned out. Crew of several guys labored for a whole day taking that garbage out. They may have been singing there in the attic, but I know that was masking the curses they may have had going through their heads as they were taking out likely 100+ bags of garbage.
When the clean-​up was done, I discovered rat nest of wiring with some of it chewed up. So Bob basically save my house from catching fire.
And that was just the start of the job.
Couple months later (took a while to get MassSave to clear me on HVAC problems I had) crew came in to do insulation on my knee walls (which are finally usable now), re-​do the attic, and do sealing around the house. Not sure how the heck they were able to do that, but I also asked them to redo my crawlspace, which they manage to squeeze into the two days they were at my house. Unbelievable!
Amanda and Tiffany (two sisters who run the company) are as exceptional. Amanda was flying through the paperwork, getting all the details ironed out, dealing with bureaucrats. Tiffany came to make sure everything was running smooth at my house, which actually wasn’t truly necessary, because the crew is very autonomous, they make the decisions what to do to hit the deadlines and finish the job properly. There is not cranky foreman watching them and it shows.
Result: my boiler is running 50% less and house feels so much warmer. I can turn off the system in the middle of the day and 2^nd floor only drops two degrees in the whole day. That used to happen in 1 – 2 hours.
I have several other insulation projects planned and Dolphin crew will be ones doing them for sure.

This company is first-​rate. Every interaction we have had — be it with the friendly and knowledgeable people in the office answering the phones, to the crew who came and performed the work has been pleasant and most importantly — EASY. They are so easy to work with, they’re clean, and they want to be successful in helping to improve a home’s energy performance, costs and comfort.
Here are some highlights of our experience working with Dolphin Insulation:
1. The background of their representatives is one of Building Science, not simply basic construction/​traditional insulation methods. The «Energy Engineer» we worked with — Chris — respectfully examined and determined how ventilation, humidity, air leakage and outdoor temperature effect the inside atmosphere and what to do in order to achieve the best results. Referring to them simply as an insulation company seems to sell them short.
2. The crew who came out to do the work was knowledgeable, careful and CLEAN. We had them remove our old attic insulation on a hot day and they gave 100% effort in very difficult working conditions just to mind our concerns over dust and air-​quality. They were excellent and highly professional even though the space they were working in was filthy and humid. Never once did they complain.
3. A difficult (creepy) crawlspace area in the basement was addressed, and our site crew leader (also named Chris) exceeded our expectations in air sealing that space as well as adding insulation and a vapor barrier.
4. They vacuumed after working in each and every area. One of the crew members even vacuumed some dust he noticed on the coffee table. This goes a long way with me.
5. In the few days we’ve had this new insulation we’ve already noticed our A/​C is working better and is more consistent temperature-​wise both upstairs and downstairs.
We will definitely work with them again. Their website is a great place to start if you’re just starting to look at re-​doing your insulation or if you’re planning to do a MasSave energy audit.
