Get matched with top insulation pros in Dayton, MD

"Highly recommend. Exceptional and professional service from their contractors and most especially by Nolan Walker (Performance Consultant). Nolan showed photos taken of my home's ductwork and insulation and provided a list of options and the cost of each project so that I could make a well informed choice of which projects to pursue. He took his time and was honest and understanding - not aggressive like other companies I have dealt with. His test-out and follow-up appointment was just as thorough. It was a pleasure working with him."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

"Debbie showed up on time and seemed knowledgable about insulation. However she had a hard time answering my questions because she was overly fixated on price. That's not necessarily a bad thing but it got in the way of me really understanding the answers. When the quote came in it was very resonable but when i emailed with a follow-up question concerning warranties, the lack of record on Angies List (despite being in biz for 100+ yrs) and a sub-contractor she was going to use for an exhaust ventilation, she wouldn't put some of the answers in writing until after I committed to using her company. After reviewing all of the quotes we received we finally decided to take a leap of faith because she seemed knowledgable and the quote was fair. i emailed saying we wanted to move forward and asked if i could i now get the informatoin i requested in writing. Unfortunately it's now been 5 days so we are moving in another direction. I bet the company does quality work but it won't be with us.

"Bob & his crew arrived on time and worked diligently to add the insulation to my home taking the time to educate me as well. They cleaned up afterwards and even patched up some nail pops that appeared."

"Mark was very professional and thorough.  He inspected the attic and  provided strategies and suggestions for insulating and ventilating the attic - and he provided a written report.
"

"They pointed out areas of air loss that needed to be covered or blocked and advised  more attic insulation which service they will provide. Their price offer seems reasonable.  I'm still crunching numbers.
"

"Overall it went well except I didn't get the other estimates I requested for insulation and gutters. This was not the low bid but they have done several cedar roofs in the area and have a good reputation. The end result looks really good.
"

"I have an old house and new addition that was not insulated properly and a sun room that needed insulation. Dan was extremely knowledgeable on what needed to be done and his team did outstanding and professional work I highly recommend them! I wish I would have hired him first!"

"They had to remove insulation and replace it."
