Rated 5 out of 5 by This dealer provides awesome service and education. Needed to replace 35 year old leaky patio sliding glass doors, this dealer took the time to show me the various product offerings from Milgard and explained how the product is installed. He explained how the welded frame construction prevents water penetration. He made suggestions on how to handle the internal trim options. And finally the product was expertly installed, on time and as promised. October 11, 2015

Rated 5 out of 5 by both the salesman and the install guys were great. Joe, the salesman was very professional. He came up with some ideas as far as the window configurations that were different from the way the old ones opened that we had not thought of and they worked out very well. The install guys, Mike and a young lad who's name I can't remember were also great. I was a roofer foreman for 30 years and never had the chance to watch other trades work. This time it was my house and I could lay around, drink coffee and watch these guys. Demo, prep, install, trim out, and clean up were all very nice. Great job !!! August 28, 2015
