Sustainergy team was very professional, punctual, and clearly did good work. They also did a great job of cleaning up afterwards and stayed as long as it took to complete the job as originally discussed. I would recommend them if you need any creative solutions to help with increased energy efficiency, cold or drafty rooms, or avoiding a frozen or burst pipe in your future.
Description of Work: Insulation blown into the floor joists below the bathroom that were also above the garage.

Finally, we have worked very hard for our high reviews and we would be grateful if you could update the rating that you originally gave us and reflect a rating that now you feel after experiencing our service.

We worked with Flequer -- he was great -- spent over an hour at our home walking through with us, pointing out various potential energy conservation measures and their expected payback. He then worked with us to prioritize since we didn't have an unlimited budget. We ended up deciding to insulate the attic first, and prioritize other projects for future years. He also did all the paperwork for us to qualify for a $250 rebate from Duke Energy -- the check arrived a couple months later, and he did all the work! Our home is much more comfortable and the project was worth every penny. The company is worker-owned which means all their crew -- from sales to installation -- are incentivized to do the job right so they don't have to come back. A great experience -- we will certainly use them again.

This was a scam from the beginning. When the contractor was contacted they stated that the service they provided was free of charge to all but Angie's customers who paid 49 USD. They come out for free to give an estimate for work to be completed later. Shows Angie's cannot be trusted. Won't be buying anything else.

Dear Mr. D., We are very sorry that you feel frustrated and the the person that you talked to was not clear enough with you, but it seems like there was a misunderstanding that could be easily fixed. Angie's List members get an additional $200 for this deal towards the work needed based on our recommendations. Only certain deals get that and certainly, not our free evaluations. I guess the miscommunication was because our company offers several services. We have basic evaluations that we offer for free, also whole house insulation assessments, energy assessments, and even energy audits. All this can cost from $20 -$400, some of them require $8000 in equipment. Mr D., we will be happy to speak with you and fix any issues that you might feel and honor the $200 Angie's List discount, as well as the energy assessment. As you can see in our site, we are a worker-owned business. We share the profits that we generate among the workers. We take pride of our outstanding reviews because we are honest and worked hard for it. We also believe that if there an issue like this that we can not solve, we should not be in business. Please, let us know how we can make this right for you and we promise you that we will do our best. Thank you. Respectfully, Sustainergy Cooperative Team.

They were excellent. Very clean, went above and beyond. They did a really nice job. They test it before and after they do the job and they give you the results so if you can get money back from the government you have the paperwork. Any little touch up paint they needed to do they did. They put tarps throughout the hallway so nothing would get into the carpet and they wore the little footed shoes. It was all done on one day. I thought the price was good, we had 4 quotes and they were competitive. Highly recommend.
Description of Work: I used Sustainergy Cooperative for new sealed LED light fixtures, insulation in attic, repaired a hole up there where the wood pecker made.

The work will be scheduled just as soon as my husband finishes some work in the attic. I can hardly wait to feel the difference and see the utility bill.
Description of Work: They came to do an energy audit. They were on time for the appt., very professional and really did a thorough audit. They seemed very willing to explain their business interest and showed a sincere aim of accomplishing a "tight package" if you will--and providing access to money saving programs thru the city and fed. govt. Also, being an employee owned enterprise, they would want to do the best job possible. They are also located in my neighborhood--more incentive to do well.
