We had 2 Milgard sliding doors installed. We knew the product well, having replaced all but these last 2 doors in synch. Every window/door in our home of 55 years is Milgard because we love their quality, the warranty, the superior look and the supreme performance. We are so happy! They are quiet, attractive, easy to use, and there’s a prestige to Milgard. Superior products always have that.
