Miller Custom Exteriors put in a sliding door for us and they did a good job. The only problem was that once we had done our initial appointment for them to sell us the product, it took a long time after that for them to actually do the installation. I actually spoke with them in October of last year and finally got a hold of them in January to come install my sliding door. Once they did the work it was fine, it was just that a long time went by between ordering and installation.

They sent out very good technicians. I will use the service in the future if I have a similar need. They never offered an explanation about the long wait time for installation, but we love our door and it was a very fair price. Other places we looked had astronomical prices, but theirs were reasonable, and it's a quality product.
