REenergizeCO

Following an energy audit I came across this Xcel Energy registered company. Dexter and his team did a great job upgrading the insulation in our attic to current standards. They were the only company that offered to squeeze into two lower attic areas to also address the insulation there. The team was technically strong, very friendly and considerate, overall everything worked out very well. Two areas that required follow-up: - attic hatch - rather than just increasing the insulation, as proposed, we decided to completely redo the hatch - dam - single wall cardboard was used around the furnace, that does not hold up to physical impact during routine maintenance work in that area. Particle board as used around the hatch should have been specified Costwise Reenergize CO was the highest of 4 quotes, but they also were the ones that were most flexible.

We recently had REenergizeCO perform a Home Energy Audit, and we were extremely pleased with the results! Marissa did a fantastic job with the audit--she was very knowledgable, worked quickly and efficiently, and was very friendly. (As an added bonus, our dog fell in love with Marissa and she might be his new best friend.) The report that we received was helpful in identifying improvements that we want to make to our house to make it more energy efficient, and we appreciated receiving an associated quote to perform the suggested work so we had an idea of how much the upgrades would cost. Overall, we would definitely recommend working with REenergizeCO, especially because of Marissa's great customer service!

I waited 2 years after getting my solar to write this because I wanted to make sure the company resolves problems that arise post-installation. They do. They have always been super responsive. Also, they just seem like nice people who are not out to steal your money. I noticed this the first time I met one of them. He came to the house to test whether for air leaks and other energy losses. In the end, he told us our house is in great shape and didn't need any work. How often does a contractor tell you that? They installed the solar over the course of two weeks. We had a panel go off line a few months later. They came out and fixed it within two weeks or so. We had a wifi disconnect, they came out to fix that too. No fuss. Great company.

Highly recommend Re-Energize. Marissa came out to do the energy efficiency audit. Scheduling the audit and later the work was easy with a very responsive staff. In the end, I decided to add insulation to my attic, following Marissa’s advice: light over the garage, deeper over the rest of the house. I trusted I’d see savings, and wow have I! Just as Marissa said, my house temperature is more even. I have reduced usage — actual usage of kWh — by a whopping 30% in July and August 2025 when compared to July and August 2024. For real. 30% fewer kWhs. With whole home AC and my 3.5 ton unit for my 3k sf house.

REenergizeCO completed an attic insulation and foam sealing project for us July 28, 2025. We scheduled the work after meeting with Dexter in June – he conducted home energy audit for us and prepared an itemized proposal for upgrading our insulation. We had numerous questions during the process, and Dexter answered each of them promptly and thoroughly. Following these discussions, we contracted REenergizeCO to complete our insulation project. The work was done as agreed and was completed in a single day. Dexter and the installation team were professional and courteous throughout the entire process. The installation team protected our rooms from dust and debris, and were careful to clean up when they finished. REenergizeCO is an authorized contractor for Xcel Energy; they acted as intermediary with Xcel to process home improvement rebates Xcel offers. I highly recommend REenergizeCO for home energy audits, insulation upgrades and other attic improvements that might be needed in your home. We’re happy to give them a 5-star rating.

I needed the crawl space under my townhouse insulated and these guys did a fantastic job. They explained every step in the process clearly and were able to get my install scheduled soon after I received the estimate. The crew was great and worked quickly to get the job done. There was a cold snap a few days after the job was finished and the amount of heat retained in my home compared to before was definitely noticeable.

This company is fantastic. REenergizeCO first did a comprehensive energy efficiency assessment that was easily understandable. REenergizeCO was extremely patient with me as I worked their recommendations down into multiple stages of work (thanks, Marissa!). They just finished sealing the crawlspace with 3" of closed cell foam and installed a vapor barrier and WOW is my home warmer and the basement more comfortable already. The workers were kind, knowledgeable, and professional. Will use this company again for the attic when I am ready for that work to be done.
