You should always get a few quotes from contractors and I suggest including Eco Energy in your list of quotes!

She is very familiar with products as well as installation techniques, and various energy program requirements. The principal installer (Josh) was thorough and efficient. He coordinated his team's work with another contractor I had onsite so as to allow both teams to work simultaneously. I was very pleased with the end result from Potential Energy and would absolutely hire them again.

My husband is in the construction industry and he isn't often impressed when others do work in our home, but even he said they did that little bit extra instead of cutting ANY corners. They cleaned up continuously as they worked and even set up plastic tents to cut back on dust when they were working in our home. I would highly recommend this company and especially this group of guys!!!

Hi everyone, Yesterday Best Home Performance added blown…read morein insulation in my attic to supplement the R-49 fiberglass from the 20 year old initial build. First of all I'm a retired HVAC contractor and I built this Green Home, so I know a lot about residential construction. I watched them blowing in the insulation and I was very satisfied with their process. They didn't skimp or take shortcuts even in the difficult areas to reach. Their cleanup after the job was done was spot on too. "I got my monies worth". Thanks, Dan B. Berlin CT.

I have contracted Nealon twice, both times Dave provided me with thorough information and…read morealternatives with competitive price quotes. First project, completed a year ago, was for insulating a single room, for which Dave suggested an alternative to my initial request that cost much less. Chris and his crew completed the work from the interior of the house in a single day, and I was exceedingly pleased with the results. Chris was just as informative and helpful and courteous and friendly as was Dave. My second project, completed last week, was for insulating the entire house with blown-in cellulose from the exterior of the house. As the exterior sidings are aluminum rather than vinyl, this was more difficult and more time-consuming, as aluminum does not bend as easily. In fact, another company informed they do not work on houses with aluminum siding as the risk of damage is too great. But Bennett and his crew were such efficient and hard workers that they completed the job in two days with no damage to the siding. Same as for Dave and Chris, Bennett's information and advice were invaluable.

We scheduled them to give us a knee-wall estimate ONLY. I…read morewas very clear about this with the nice girl on the phone. She verified that is what would happen when she re-confirmed the appointment. I never got any estimate for the knee wall, because he noticed we were not going to agree to cutting holes in the ceiling, roof and siding, in order to do the entire house. "I want to get you on the schedule today." He finally agreed to email(2) separated estimates. One for the knee wall the other for "demolishing our cape." Nothing....hard pressure sales tactics. Moving on.....

We bought our home last December and quickly realized we were in need of insulation. When you buy…read morea new home it takes a while to get to know its quirks, what it needs and set a timeline for improvements. We put insulation at the top of the list. Our oil delivery costs for astronomical. The house didn't retain its temperature so one minute it was warm and the next very cold. The furnace was constantly coming on and off. A huge expense for our family. Once we had the insulation installed along with air sealing around our entire home we were hoping the next winter would go better. So now that it's winter we can say that our furnace does not constantly click on. Our home retains the heat. We set our thermostat at around 66 degrees knowing it will get up to 68 and sometimes 70 if we are cooking. Our oil deliveries have been way less gallons per deliver, we are using less fuel to maintain the heat in our home. Installers were professional. Clive and his team were very considerate of our home, keeping it clean with drop cloths and removing all the old insulation carefully to keep the house from collecting drops of it. It is amazing how they build up walls in the attic with a small space to walk. The air sealing in the basement has been nice because the heat in the finished portion doesn't kick on as much because its not being sucked out of the house. The job was done in one day. It was our first Summer in the house and we had the work done right before that, so I cannot tell you what a previous Summer would have been like but I can only imagine how hard the A/C must have had to work to keep the house cool. And, the cost must have been really high. Our A/C is in the attic so they insulated the duct work to each room as well. Keeping the air traveling in the duct work cool as it traveled from the a/c to the room. Meaning again, it doesn't have to work so hard to keep the house cool. Genius! I will post this on CT Basement Systems too because I think there are more reviews there for the insulation.

Update March 2026: Nearly 11 months after the installation on April 9 2025 the odor and concerns…read moredescribed below remain unresolved and our upstairs space is still affected. I am updating this review to reflect our ongoing experience. I am sharing our experience with USA Insulation of Connecticut so other homeowners can be aware of the issues we encountered and make an informed decision. 1. Strong chemical odor Immediately after installation our daughter's room had a strong smell similar to burning rubber or a yoga mat. The odor becomes stronger with humidity and it has not gone away. 2. Unlivable conditions Because of the smell our family had to move downstairs. Our upstairs space has been difficult to use since the insulation was installed on April 9 2025. 3. No noticeable cooling benefit We were told the insulation would help improve cooling upstairs. In our experience we did not notice a meaningful difference after the installation. 4. Health and safety questions We asked the company if they could confirm whether the product was formaldehyde free due to concerns about phenolic resins. We did not receive documentation confirming this. 5. Safety Data Sheet concerns An independent environmental testing company told us they could not proceed with testing because the Safety Data Sheet that was provided was missing information and did not follow the standard format they expected. 6. Communication challenges We had difficulty getting clear answers about our concerns and were not able to have the situation reviewed by someone higher within the company despite asking several times. 7. Removal offered with conditions The company did offer to remove the foam at no cost. However the proposal required signing an agreement releasing the company from future claims and liabilities. Because our concerns about the odor and the situation remained unresolved we were not comfortable agreeing to those terms.

I hired Valiant to put in an "underground" propane tank and generator. They sent several people to…read moretalk to me and each one contradicted the previous person. There was finally a decision and I was sent an estimate to sign. Part of the contract is that any damage done to the property is not their fault and I signed because I think this is pretty standard. All the the workers they sent were great, EXCEPT. it appears the quote I signed and paid for was not at all complete, so to dig the trench was another $2600.00. Then the surge protector was not added so that was another $650.00 These upcharges just kept coming. The Tank was NOT buried as I has asked, but is above the ground and a real eyesore. They willed the tank without asking my permission. The damage to the property is terrible and I have no way to repair it. The last people who came said they would check back, but I have never heard from them. I saved 20 years for this work and to have the mess, and all those up-charges has been terrible. The photos show some of the damage. Valiant said they would leave oil which they did not, they said they would come back and set up an App which they did NOT, they said they would contact me about an extended warranty which they did NOT. There were supposed to contact me about service and they did NOT. It was beena miserable experience. Now I have a generator which may or may not work I am out almost $30,000.. 20 years of saving.
