I am going to be putting a patio door out the back of my house. I would like to put a double door, where only one side swings open. I have checked the prices on many of the doors. Originally I was going to get an Andersen. However I have noticed that they are so much more than most other doors. I went to Home Depot, and they also have models from Peachtree and some other brand that begins with an A, I forgot the name. Is it really that big a deal if I don't buy an Andersen. The doors seems to be pretty well build but I don't know. Any help would be apperciated.
