Randy is the most passionate person ever regarding Attic insulation. Super knowledgeable, helpful, and honest. Excellent communication and work rate. Whole team is amazing. They ripped out my insulation over the attic, seal foamed every entrance possible, and replaced to R-49. A killer big job, and I’m super happy with my choice to book Paragon.

Heather Rocen

Randy was very professional and helpful. I had a lot of questions and concerns and he answered them with patience and in a common person’s vocabulary. He went through all of the steps he was going to do. Provided before and after pictures and was just so helpful. I appreciate him driving a long distance to help me on super short notice! I will reccomend him to anyone who needs insulation.

I was very impressed with the workmanship these guys have. I had them insulate my attic and spray foam insulate my walls in my new addition to my home.
Professional, Timely, clean, and well priced. This company deserves your business.

Paragon sealed my driveway last fall. We have an extremely long driveway and they did an excellent job. Looks brand new and I’m more than satisfied with the quality and customer service. Great Company!
