"I had a wonderful experience with Founders Insulation. They were extremely easy to work with. It was easy to schedule an appointment, the gentleman who came out was knowledgeable and polite, and I felt that I received good information and they did not try to sell me something I did not need. Their quote was excellent. The work was scheduled and completed quickly. The installation team was courtesy, thorough, and knew their stuff. They were respectful of my home and went above and beyond. I highly recommend this company."

Even in the face of obstacles due to the nature of my unique attic, they overcame and completed the project on-time and to complete satisfaction, absolutely astounding job! A giant thank you to the crew; Brad, TJ, JB, Jeremy, Anthony, and Jason!"

"I selected this company because they are a member of my energy provider's energy saving program network. The customer service was top notch and the insulation installation team was top rate. There was a problem with the aeroseal team assigned to seal any holes in the air vents. The aeroseal solution leaked throughout the house, even into drawers, closets, on clothes, everywhere. It took over a month to clean up. Throughout this process, the owners remained in contact and assisted as best they knew how. The cleanup was stressful, but in the end, all worked out and I have noticed an improvement in energy savings. Thanks!"
