  I have used Attic Nerds for the 3rd time. Dan has consistently underpromised and over delivered every single time. If a very high quality product coupled with unbeatable service is important to you, I highly recommend Attic Nerds for your insulation needs!

  Dann Knapp is dependable, hardworking, honest, and genuinely cares about serving people well. He approaches everything he does with excellence and integrity, and I have no doubt he’ll treat every other customer the same way. I’d absolutely recommend giving him a call.

  This company is AMAZING!! Dan came out to give us an estimate and told us what the job would include and how long it would take. The crew showed up on time and were able to complete the job a day ahead of schedule. They were polite, thorough, and clean! We couldn't believe they even vacuumed my closet (attic door is in master closet). Bonus: The insulation they put in will save us money on electric too! This company is top notch with excellent customer service. Thank you! We are super happy with the job and highly recommend this company and its team!!!

  We called Attic Nerds to address our attic insulation and venting needs. We recently had our house repiped and now have the waterlines in the attic as well as having a complete roof and deck replacement. Chris came out to our home and did a thorough evaluation. During his inspection, he found 3 different types of insulation material in the attic, water pipes not properly insulated, evidence of rodents, and no soffit vents in place. He documented his inspection with pictures that he showed us later. He then gave us several options on what we could do to best serve our needs and budget. We decided to completely remove all the insulation and apply a uniform R60 value application. Because of the new roof there was a lot of debris mixed in with the insulation. In fact, the installer made the statement that ‘It looks like a woodchipper was in your attic”. We are glad that Chris recommended removing all the old insulation. We also tented all the water lines to better insulate them from winter bursting. After the total removal of the insulation, tenting of waterlines, and sealing all areas of air leakage, the installer asked me to come up to the attic to examine their work and explain what they had done. We also decided to insulate the area over the garage. The only problem we had was not removing everything from that area. The fine dust from the insulation covered all the boxes and items we left in the area over the garage. While they tried to keep it to a minimum and cleaned up after, it would have been best if the attic space was empty. Throughout the entire process Attic Nerds kept me informed of the progress and addressed any problems that arose. We are very pleased with the quality and communication with Attic Nerds and are looking forward to a more comfortable house and lower utility bills.
