"What an absolute DREAM! Correct Energy is an incredible company. Knowledge, professional and efficient! I contacted a few insulation companies but the proposed methods were not through. Correct Energy and especially Ray’s knowledge and experience were above and beyond. CE came out to assess and spent a generous amt of time explaining EVERYTHING. CE came when they said they would. The crew was professional and spent a few days here. They left everything immaculate. My place is old, built in the 1940’s so many challenges came up that they handled like absolute pro’s. Their work has and will continue to save so much on energy, the difference of before and after is immediate and drastic. I can’t wait for them to come back and do my basement next! I can't say enough about this company. Pros work here!!! Hire them!!! You will not be disappointed.."

"Excellent experience from start to finish! The home energy audit showed me where I was losing heat and areas that needed attention. Getting the house sealed and getting blown in cellulose and an attic cap installed professionally is something I would recommend to any homeowner. Expediant energy came to install it soon after the initial estimate. which in this winters bitter cold temps is something I really appreciate. I Noticed the difference immediately. Anyone who is paying for heat and looking to improve their insulation should give these guys a call you won't regret it!"

"Dan and Josh were incredible. Not only were they both friendly and extremely knowledgeable, but the were early on the day the work was to be done. They explained exactly what they were doing. They showed me progress along the way. They had recommendations and were adaptable to my schedule. The results were shocking. We live in an old lake house and really needed to improve the insulation. There were spots where there was little to no insulation and some where there was insulation but not enough. Even the first night the difference was amazing. I can't recommend Dan and Josh enough. So worth the money I spent. You need insulation hire them. I promise you will be thrilled."
