"I hired Atlas Home Energy Solutions to remove old insulation and replace it with the foam technique. However, I ran into numerous unexpected problems due to a slow leak from old pipes. It took awhile to sort out. Atlas Home Energy Solutions gave me lots of expert advice. They were willing to come out and review the situation. They were also willing to reschedule and wait until another contractor dealt with the water issue and its ensuing problems. They helped me make some difficult decisions before they could insulate the crawl space. When it was ready for them to come and insulate the area they bumped their schedule forward to get it done. This company did sterling work. Their expertise and professionalism were outstanding. They really know what they are doing and guided me through a more protracted process than originally envisioned. I would highly recommend them to anyone."

"Highly recommend for any insulation project. Dan Hope is extremely knowledgeable concerning home insulation and was pleasant to work with. I have cantilevered second story floors and poor insulation was causing a duct vent to develop condensation with this 2024 heat wave which caused moisture to drip down inside of my first floor ceiling. Dan fixed the insulation issue and then some. He inspected the house and advised improving the insulation around a room that sits above our garage that was notoriously difficult to temperature control. I would hire him again for another project in a heartbeat."
