Dan R., Duluth, MN

"I am very pleased with the work Northstar performed. They were right. It makes a complete difference in both sound and warmth. Thank you for your kindness and professionalism."

Paul & Kristin Norlander, Woodridge New Home Consulting

“Just wanted to drop you a quick note to thank your company for the excellent job you did on our new home. Icynene® spray foam insulation has been fantastic for us. We will never again use a batt insulation system. Icynene® spray foam insulation has provided us with a very comfortable home. It works great with the in-floor heat system we installed, providing a highly energy efficient home. We will definitely recommend Northstar to friends and future clients.”

Tom & Mary Wright

“Thank you very much for the wonderful work you did for us. The Icynene® Insulation is super. We are heating our entire new house with just a space heater, while we finish the rest of the job. You and your workmen were prompt and professional and we would recommend your company to anyone interested in insulating.”

Paul T. Paczynski, C.P.A.

"“I am writing to thank you for the excellent job you did insulating my office building. I appreciate that you were on time and finished on time. Your employees were courteous and did a very good job of cleaning up. As far as your product, it has been in my building now for over a month. My most recent gas bill showed a drastic decrease in usage and I have noticed a big difference in overall comfort in my office. Thanks! I have already recommended you to other people and will continue to do so.”

Tim & Gail Larson

“We just wanted to let you know how pleased we are with the Icynene® insulation you installed in our new home. Even with rising energy costs, our monthly utility bills have been much lower than we expected. This is without any exterior siding on the house, which has yet to be installed. We enjoyed working with you and would certainly use your product again.”
