Hired Energy Nerds to reinsulate our attic after having condensation problems. They guaranteed they could fix the condensation problem by removing all of the old, wet insulation and reinsulating the entire attic. Also promised to seal air penetrations around can lights and other openings. They "sold" us on including a blanket barrier that helps with the insulation. The blankets were thrown and installed haphazardly throughout the attic and did little to help solve any problem. A vaulted ceiling in the attic was never properly insulated as they said it would be. There was little insulation installed above the attic despite indicating they would insulate this to the same level as the remainder of the house since it was a heated garage. Kayden from their company came out after the fact when we started having condensation problems again. He blamed it on poor venting, not on their insulation job. Why was this not noticed earlier??? Kayden ultimately washed his hands of the project and left us hanging. Overall, what they did was a joke that cost us about $18,000. Shame on us for putting trust into their sales pitch. I am now in the process of having to get the work done correctly to the tune of another $15,000. I would NEVER recommend this company to anyone having insulation issues.
Response from Energy Nerds
"Hi Kevin, When Kaden came out last, we thought it was understood that the spray foam over the soffits was a serious issue and that you were going to contact the folks who constructed the home. Please call us and we will do all we can to help. The insulation and blanket are proven to help insulate but if ventilation is impaired as it sounds it is with spray foam over soffits, then that has to be addressed. We do not recommend ever covering a soffit with anything. We look forward to continuing to help out."

Prompt, thorough service, great communication throughout. Removed wet, damaged insulation due to roof leaks following derecho damage & poor roof repairs. Mitigated mold. Filled gaps, replaced insulation, installed proper vents on roof to improve circulation & prevent future humidity & mold between layers. The air temp and humidity in our house is amazingly stable now. So much more comfortable. The air conditioner no longer runs constantly and the upstairs corner closets donâ t accumulate excess heat from the roof. Impressed to find hard-working labor who know what theyâ re doing.

Initially, the customer service was great and we both came to an agreeable path forward to address my attic needs including removal/install of eco fill insulation, exhaust fan ducts, air sealing, and HVAC Wrap Aeroshield. I was not very comfortable with the price but moved forward anyway and the rep did a great job of selling me on how everything will be addressed when they are done. At first, we thought that everything was great. I placed a temp/humidity sensor up in the attic just to make sure we were good up there. Unfortunately, humidity kept rising to an unsuitable level (70%-80%) whenever the heat was on. After further inspection, the HVAC Wraps were not done with the above job and it looks as though there was an attempt to just cover all of the ducting and plenum with blown-in insulation. We also noticed the soffits were covered with blown-in. we had to address this with a roofing contractor which was an additional $2k expense on top of the $6k job above. Needless to say, we still have HVAC insulation issue that I am sure we will need to address before summer hits. Sent email with no response.

Our team Ryan & Kayden were very punctual and professional. Very thoughtful and kind demeanors. They vacuumed the back entry and garage when they were done and were very polite. They also took before and after pictures for us! Looks great! With energy prices increasing and supplies of insulation slowing I would recommend you hire this company as soon as possible! Worth every penny!

I wish I could give them a 10 star rating!!! David was excellent throughout the process. He kept me informed and let me know what was happening every step of the way. Ryan headed up the work team when they removed the old insulation from my attic and then blew in new insulation. It was a challenging job and they met every challenge with a great attitude and performance excellence. I would recommend Energy Nerds, without reservation to my family, friends and anyone else who values a job well done at an affordable price. They provided excellent value and it has made a difference in the comfort level in my â centuryâ home. In addition, David recommended The Batmen for the bat abatement issue in my attic. This was a timely and valuable recommendation and The Batmen (Omaha Firefighters) did a great job, quickly. Start to finish The Energy Nerd team was awesome!

I do have to say their clean up was a little lacking. It would have been nice if they had hung some plastic to cover up the shelves by the access panel. I had some work to do to get that cleaned up. After coming coming back a second time, they were more thorough, but still left things behind. Not a big deal, however, since insulation was dragged through the house, it a good idea to give the floors a good cleaning anyway. I did get QUALITY installation! If I could, I’d give these guys 10 stars! They worked hard in the attic with the attention, and detail that I would have given (I’m perfectionistic, and have high attention to detail)! The communication during the process was great until it was time to leave. I went into the garage for a little while, and when I came back in they were gone! I had no idea they left!pThere was one minor communication issue between sales and the installers, but that was quickly resolved with one phone call. I really like that they take pictures of before, during, and after the process. I can see everything they did, and KNOW that things were done exactly how I wanted, or needed them done. That put my mind at ease, and took my curiosity away. Otherwise, I would have had to open the access panel to look for myself. Yuck! Overall, it was a good experience, and I am very happy with the results! I would definitely hire them again! Thanks a lot guys!

Like with many businesses you get what you pay for! I could have found another company that is cheaper but I know good service when I see it! This company is exceptional in every aspect. My insulation has made a tremendous difference before they were even finished! My recommendation is donâ t look any farther than this company cause it is very hard to find a business that can perform to a customers standard these days! Thank Daniel, David and crew for an A+ job well done!

This job was in very difficult working conditions as it was a storage area and crawl space with dirt base. The crew initially removed the old insulation that was falling from age and collecting moisture and replaced it with a much thicker RValue. For most of the job, they had to lay on their back to remove and install the new insulation. The crew leader Ryan did a great job of communicating as he called me the day before the scheduled install date and advised me of anticipated arrival time. Called again while en-route to provide ETA. After completion, they did a good cleanup .

The professionals at Energy Nerds insulated a drafty fireplace box on my home and sealed up other areas of concern. Dan Garvey discussed the project with me, answered all my questions and acted as General Contractor, coordinating multiple crews in a timely fashion to get the job done. Dan is the fella that you tell other home owners looking for a trusted contractor, "Hey, I have this guy." Dan and his crew are those guys! This year I'm having Energy Nerds doing insulation work in my garage as well as acting as my General Contractor for hail damage to my home (roof, gutters and siding, etc). I would recommend Energy Nerds and Dan Garvey to anyone looking for a contractor who visibly cares about his clients. These folks are top notch and you can rely on them to take the worry out of any project... they will take care of you and your home.
