“I wanted to give a special thanks to Fernando and the guys for clean, fast work. Communication was always good and they explained what they were up to at every point in the job. Our attached porch holds temperature as well as the rest of the house now. Would easily give this team a call again and happy to recommend to others.”

“The service was excellent. The real test came over the winter—the upper floor and attic stopped losing heat for the first time in years just Northstar promised. It was professionally done and we have no complaints about the service or quality.”
