"Had a visit today from Primary Home Improvements! Great team and awesome service! We now have insulation in our attic. The guys that came today were awesome! Have you ever expected a contractor and they showed up hours later than planned. These guys were not only on time but immediately began working. They were done in plenty of time and even vacuumed leaving our home in better shape than when they arrived! We highly recommend Primary Home Improvements for your insulation needs"

"Fast work. Great communication up until trying to communicate with project manager. Was told everything would be completed within two days. The roof was done in one which was awesome, but I am still waiting on gutters a week later and won't be given a day/time for them. Just keep being told "early next week" or "tomorrow". Sales portion and inspection went great. Fantastic everything up until the install."
