Response from Dolphin Insulation Inc
Its too bad that this person gave us such a poor score. I looked in our data base and this name or address is nowhere to be found. If it was strictly because of the price, I feel bad for them. Homeowners who pay half of what we charge never get what they expected. If you think about it, we can always do half the work for half the money. But then we wouldn't be doing right by you. I am teaching my daughters that Integrity is the greatest thing we have to offer our community. We aren't going anywhere, and we have more knowledge than most in this industry. Why not use it for good instead of bad. Thank you for taking the time to read this. My name is Christopher Alphen , and my hopes are that Dolphin Insulation stay around helping homeowners for years to come. My daughters run this Team excellently and I am incredibly proud of their work ethic and commitment to this Community.

Description of Work: From the first consultation down to the final day of insulation work nothing but professional and informative work. All team members worked extensively all day and made sure the house was left clean each and everyday after they left. We have experienced the difference right away. The heat and ac systems have barely been on the house has kept itself at a nice temperature, the complete opposite of what it was before. Many thanks to Dave and his crew. - The DeAmicis family.

Response from Dolphin Insulation Inc
Hi [Member name removed], I would recommend hiring an insulation contractor that has chosen to do work for the MassSave program and they can help you fill the gap in your basement under the price that MassSave has already quoted you at. We do not work for the MassSave program any longer and a quote from us wouldn't be beneficial as MassSave already has set prices for their scope of work. Good luck with your project.

Description of Work: The technicians were professional, friendly and knowledgeable. They insulated the attic in February and had to return in April because the snow drifts were over 4 feet around the outside of the house. Both visits went very well and I have recommended Dolphin to my friends and neighbors.

Description of Work: David Posluszny and his team arrived early morning and proceeded to prep the area, including laying and taping plastic over the entire staircase and laying tarps down on the hardwood floors. They removed all fiberglass from the attic crawl space in bags and stored neatly outdoors. Air sealed the entire crawl space area where needed. They all were very professional and answered all our questions. For the past forty years we have used an airtight Consolidated Dutch-West wood stove in the basement as a secondary heat source. Since Dolphin Insulation installed cellulose insulation using David's airtight techniques we have noticed a big difference in the warmth of our home. We have had 6 below zero days. Our thermostat was set on 64 degrees and the house has maintained a 70 degree temperature just by the wood stove. Maintaining this temperature in the past has never been possible. The oil furnace turned on only to produce hot water. We are looking forward to huge savings on heating oil this year. We are living proof that cellulose insulation installed using David's air seal techniques does work and is very effective in preventing heat loss. Thank you Dolphin Insulation for a superior product ..and thank you David Posluszny and his team for a job well done.

I started by talking to Chris at Dolphin first. Then filled out the paperwork to got throught the MassSave energy program. MassSave came and assessed my needs and recommended all the work mentioned above. They told me what it would cost +/- a little. I think I wrote a check for $90 on the spot, and I expected it to cost around $300 when done. Dolpin insulation contacted me after they were informed by MassSave (I think it was a few weeks). They scheduled it a couple of weeks out from there. The did the work mentioned above. They were polite, knowledgeable and fast. They cleaned up well so I didn't even know they were there. After it was done, I paid the balance (I think $200) and thought I was done. MassSave actually sent me a small check back becasue it cost less than expected. I think the total cost was over $3000 and I paid less then $300. We noticed a real difference in warmth last winter. The floors felt warmer, and the overall house felt warmer. Our family room used to always feel cold (even has a skylight), but now it was as warm as the rest of the house. Our heating bills were lower, so we actually felt we could afford to turn up the heat another degree or two. It has been the #1 thing that makes our house feel warm. When we did the windows, we did not feel as increase in warmth -- they just work better. I think the blown cellulose insulation over the fiberglass filled in all the gaps that you get with fiberglass. I recommend that you get blown insulation before you replace your windows if your goal is to save energy and stay warmer.
Description of Work: I had Dolphin Insulatiion do Air Sealing and InsulationThe air sealing was done first, and then insulation was done by another team the following day. They air sealed the basement sill and areas in attic where air could flow, put door sweeps and weatherstripping on doors, put a Thermodome over the pull down attic stairs and built another around the whole house fan. The following day, they put blow cellulose insulation in a hard to reach attic space and the main attic space.

On the day prearranged to begin the work, the Dolphin team arrived in a large truck that was hauling an even larger trailer. They got right to work, starting in the attic and working down to the second and first floors. I cannot overstate how impressed I was by the diligence, good humor, expertise, and care that were consistently demonstrated by Eric, Seth, Tom, and Max from start to the end of the project. Each day, they painstakingly unpacked mammoth hoses, myriad tools, drills, tubes, bundles of insulation materials, drop cloths, sheets of plastic used to contain the fluffy cellulose material that they were blowing into the walls, and multiple ladders. And at the end of every day, everything they took out was methodically returned to the truck and trailer. Insulation installation is a much bigger deal that I had imagined. It involves skill and muscle as well as a lot of just plain hard physical labor, heaving and lifting stuff and going up and down ladders and being pummeled all over with sawdust, cellulose puffs (light cottony bits that blow easily around and stick to sweaty faces and arms). But in addition, the crew had to deal with very hot, humid weather conditions, thunder storms, sudden downpours of rain, and very challenging parking spaces for their large vehicle. And the job was further complicated by several interruptions resulting from an irate neighbor who did not understand the nature of the work and demanded that various officials halt all work until they could demonstrate that the insulation installation was not a danger to health or the environment. When confronted with unexpected problems and complications, the Dolphin crew never lost their cool, but rather, worked through them until they were resolved, and they were invariably pleasant about it. The installation took longer than had been expected due to various interruptions beyond the control of the Dolphin team. They received terrific support from their colleagues back at their office. When a wire was inadvertently cut as they were drilling, the "home office" immediately arranged for an electrician to come and fix it. And they carefully measured and tested both before and after the job the extent to which air was coming into the house from outside. Having my house wrapped in a cozy protective cotton cloak is already making a perceptible difference. The house is definitely keeping cool with less air conditioning. And I'm amazed by how street and sidewalk sounds have been reduced. This insulation is a good thing! One final note: every day that they were here, one or other of the crew went through every space they had come in contact with during that day and swept and vacuumed debris and whatever else was on the ground outside or floors and steps inside. You would never know that they'd been here. AND, on Saturday when rain was predicted, someone came to the house from the Dolphin office to install protective seals that would keep the inside of the walls dry. This is a company that is hard-working, committed to improving the environment, respectful of each other and of their clients, very skilled in what they do, and they do it all with a smile. I don't think anyone could go wrong having Dolphin Insulation improve the energy efficiency of their home.
Description of Work: A comprehensive evaluation of my house by Conservation Services Group (CSG), arranged through MassSave, identified several areas that were not energy efficient. CSG recommended reducing air leaks to the outside (air sealing) and increasing the amount of insulation in the house to improve my home's energy performance and reduce energy waste by as much as 26%. Dolphin Insulation, Inc. is a contractor that participates in the NSTAR Gas Weatherization Program, which supports the efforts of MassSave to promote energy efficiency throughout the State. I delegated to CSG the choice of a participating contractor approved for the Weatherization Program, and Dolphin Insulation, Inc. was selected. Three improvements were recommended by CSG: Air sealing to reduce the infiltration of air into the house from outside; adding insulation to the third floor ceiling and walls (which had no insulation at all); and, filling the cavities in the exterior walls to create a thermal barrier and reduce air infltration. In general terms, this describes the work that was provided by the Dolphin Insulation team. It was a big job, and it took almost a week to finish.

Description of Work: i chose dolphin insulation to perform the work after an audit by the Conservation Services Group originally, i chose a subcontractor who had a lot more reviews on angie's list, but the required wait turned out to be four-five months: winter would have been over by then. dolphin is an approved csg contractor, though they had no insulation reviews on angies list, and was able to complete the work within a month. they air-sealed the attic, insulated the walls and garage ceiliing with dense-packed cellulose insulated a couple doors
