Rated 5 out of 5 by from Red Carpet Service The sales team was very informative and helpful the whole way through. The installers were friendly and very professional the whole time they were in my home. They worked quickly and efficiently to make sure my windows were installed to perfection. They answered any questions I had and walked the whole job with me to make sure I was satisfied. Their goal is to provide the best experience and service which they did. Working in the customer service field this isn't something that is seen all the time, but they certainly know the right way to take care of customers and roll out the red carpet.

Rated 5 out of 5 by from These windows are beautiful and a breeze to clean! We just replaced all the windows in our home with Milgard double hung in most places and sliders for the big ones. They look amazing, are sturdy and solid, and the double hung windows are especially easy to clean and maintain. They fit very well, went in in one day. No more drafts, these windows seal firmly and completely. Locking mechanism feels very secure. I am very happy and would recommend these to anyone.

Rated 5 out of 5 by from Outstanding Windows I had new Milgard windows installed in my house and shop. The upgrades to both buildings is excellent, drawing praise from my neighbors and causing me to just stand, smile and admire the improvement the product has made. This has been one of the best investments I have made, and would not hesitate to recommend the product and service I have received.

Rated 5 out of 5 by from Lake Washington Windows: A Very Enjoyable Experience! Eight years ago, we replaced several windows and a sliding door with Milgard Tuscany but we were dissatisfied because our contractor did a poor job installing the exterior trim. When we decided to replace the rest of the windows, we spent significant time researching contractors and then hired Lake Washington Windows & Doors. After reading reviews from various sites, we met with Jon Wood, a sales rep, in July. He is very knowledgeable, courteous, responsive, friendly and professional and does not use high pressure sales tactics. To address my concerns about the primed trim color not matching the color of my house, he offered to have it delivered in advance so that we could ensure it was painted correctly. Among the 6 bids we received, Jon was the only person who sent a detailed quote. His quote was transparent and his bid was the most competitive. While we highly recommend Jon we were also very happy with the office staff and installation team. The installation team (Mark & Ryan) was very friendly, respectful, focused, meticulous and professional. Before they took out the old windows, they covered the interior side of windows with plastic and tape so that no dust or cold air could come in. They vacuumed the area and carpet after each installation. They cleaned our driveway and yard at the end of each day and cleaned all of the windows when they completed the project. Even our neighbors commented about how impressed they are with the quality of the work. The installation team maintained their friendly, helpful attitude throughout the process (a whole week) and made this a very enjoyable experience for us. Tahlia, a sales coordinator, was on top of scheduling the critical measurement, installation and trim delivery dates. She was thoughtful and professional. Mike came to do the critical measurement and gave us fair amount of useful information that we were not aware of. As an ex-Milgard employee, he was also very knowledgeable, friendly and professional. Dale, a project manager, stopped by a few times during the work and made sure that everything was on track to get the job done right and on time. We chose Milgard because it’s well known for quality products and provides a lifetime warranty. In addition to Milgard's lifetime warranty, Lake Washington also provides a 10-year installation warranty, which is far better than the rest of window contractors we met with.

Rated 5 out of 5 by from beautiful windows We replaced two huge picture windows in the front of our house with Milgard windows, plus two bathroom windows. On one of the bathroom windows we selected "rain" which looks like rain drops sliding down the pane so that people outside cannot see through the glass. Everything is absolutely beautiful and solidly secure. The white trim is perfect and brightens up our house - it feels like we have a new house. I will use Milgard windows again for our next project.

Rated 5 out of 5 by from Great improvement to our home We had Milgard fiberglass windows installed in our home - we immediately noticed the improvement in temperature regulation. And I might add they look great! And....with a recent heavy rainstorm, the inside stayed dry as a bone!

Rated 4 out of 5 by from Fantastic windows, just a few glitches The quality of the windows is great. They were not all ready to be installed on the same day though -- I had to make some assertive phone calls to get them in time, which caused some anxiety, but they eventually made it. One of the mechanisms (to open the lower part of the double hung windows), broke the first time we used it, but they were pretty prompt about replacing it.
