Hi Veronica. I can tell you of two experiences I've had with Andersen doors. My first experience was when my husband and I had an Andersen sliding patio door put in our old house. It worked beautifully! I don't know the model # but we put it in in 1995, and it was vinyl clad on one side and bare wood on the interior, and at the time cost around $900. Our second experience has been so-so. We recently moved into a home built in 1987. It has Andersen sliding patio doors (6 sets of them). They are all well insulated, but they are heavy. They don't roll well (even after the rollers were adjusted). And the outside strips of flashing are coming loose (we have had to screw them in several spots). The house is well built and the materials used were not cheap, so I don't think the builder half-assed these doors. It amy simply be that these doors are older, or a cheaper model, or perhaps they have problems that have since been corrected. Overall, however, I would recommend Andersen sliding doors. But I would suggest that you try them out on a display first. Although displays are only a rough approximation of what the will feel like in your home, it's better than nothing.
