We are so impressed with Prime’s level of customer service. Right from the initial conversations, home visit, estimate, ordering process, delivery and installation we were very pleased. The quality of our new patio doors and the level of craftsmanship that went into installation is something we’re already getting compliments on from guests. We would highly recommend Prime Windows and Doors and their services. Thanks for a great experience!

I just had all 12 of my windows replaced this week. Prime Window did an amazing job. Excellent quality windows. Thank you, Steve Wilson. They sent great crew to get the job done in one day. All the windows are professionally installed, moulding replaced and caulked. Debris removed promptly upon completing the installation. We walk around to check all the windows to see how they look and work. I’m very pleased with my new windows. They work great. I set my AC at 22 and it’s cold. I will definitely use Prime Window again in the future when my door is ready to be replaced. I’m glad I chose Prime Window. Definitely recommend this company.

I have only the best things to say about everyone I dealt with from Prime Window and Doors. I was introduced to them through the Home Depot installer program. I am so glad I was. Chris came to our home and discussed our needs with us and recommended a fantastic door that was far less expensive then what we had been looking at but with all the same features. The installers were fantastic as well. They left everything clean and tidy and where very keen to ensure we were satisfied with the finished product. I will definitely use them again when I have my front window replaced. Thanks again to a company that clearly prides themselves on customer satisfaction. Kelly and Mark

"Replaced our sliding patio door. The install crew arrived on time explained and showed me what they would do. Removal of the old door and replacement with new was very quick. They also installed interior trim that perfectly matched our existing baseboards. We are very pleased with our new door."

“Very professional and conscientious, good quality work. Did what they said they would do, at the price quoted and completed work within timelines. Polite, respectful and cleaned up after themselves.”
