I hired The Patio Door Guys to install a new patio door for me ( a sliding door, 5 by 7 feet with sliding screen door). I had hired them previously to install a new front door, and I was so happy with it I had them come back to do the patio door. They came promptly and did an excellent job. It turned out my old patio door had been very unlevel, so they leveled the opening before putting in the new door. They put new siding around the new patio door on the outside, and put new trim on the inside around the door. The trim looks like a luxury to me, since the old door did not even have inside trim. The new door is an Alside brand door, and it is clearly very good quality. It slides nice and smooth and the lock works well. It takes up much more width than the "builder grade" door I had before, so I know it will have good insulation properties in the winter. It is designed to not collect so much dirt in the bottom track of the door. The screen door also has a lock. Everything was installed perfectly and they took the old door to dispose of it. The owner of the company was there on the job, supervising and working along with two other carpenters. The communication with me was very good before, during and after the installation. Tom even did some trim work and floor work in another area of my condo at no charge, just as an extra to help me out. Two other people in my condo complex have already asked about my new door, so I recommended The Patio Door Guys since I think they do such great work, and at a reasonable price. I would definitely hire them again for any patio door, outside door or window work in the future.
