Install or replace interior doors- 30 Sep 2026
We wanted to modernize the look and feel of our home, so we had Proflix install eight new interior doors for our bedrooms, bathrooms and closets. It was a pleasure working with Proflix. The price was very reasonable, the workmanship was meticulous, and he was quick, tidy and professional throughout. He asked thoughtful questions to make sure everything was right, and even noticed that one of the handles didn’t match. When I confirmed I wanted it to match, he took the time to drive to Home Depot and back to fix something I had overlooked. That kind of attention to detail and willingness to go above and beyond really stood out. We’re very happy with the finished result. Thank you, Proflix! I will post this on google too!!

Install or replace exterior or reinforced doors- 27 Oct 2025
We purchased a new Composite front entry door with composite frame, sidelights and a triple latch system. We also purchased a new rear sliding door. We shopped around and their price was indeed the lowest by several hundred dollars. Unfortunately, the door had to be replaced 3 times due to very evident defects in the factory finish. In the end, the door frame wasn't installed square to the house so the door doesn't hang square in the frame. it looks good if you don't look at the obvious uneven spacing between the door and frame. They couldn't fix it, so as compensation, the boss offered me a discount on any new work I need. I do need windows, but why would I buy more product from them after that. I gave them three stars because they tried to remedy the screw-ups and the door does look good if you don't pay close attention to details.
