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 What a difference new vinyl windows have made We lived with our old aluminum windows for several years before deciding we had enough and needed to get new ones. They were difficult to open, developed condensation during the rainy season and let the cold come in during the winter because of the aluminum metal and the gas filling between the panes had mostly dissipated. With the new Milgard windows, not only do they look so much nicer, open and close so easily, but the vinyl does not transmit the heat or cold through like the aluminum did and the new Argon gas between the panes does the same for the glass portions of the windows as well. In addition to the quality of the Milgard product with it's lifetime guarantee, the staff and installation crew at Lake Washington Windows and Doors are all very courteous and pay attention to detail to make sure that the whole process goes smoothly from beginning to end. They are so good, that our Condo's HOA has made them the preferred contractor to install the Milgard Windows here, since from experience, they are the one's who have done the best job in properly installing windows at our complex.

Rated 5 out of 5 by from Excellent UV protection; looks great My kitchen picture window is 8ft wide in direct sunlight all day. Temperatures have been 80 degrees this week. When I put my hand on the counter near the window during peak times, the counter and kitchen were cool, not hot like the old window. Im not sure I need a covering on them cause they are so efficient! Also the wood trim looks so lovely. the windows exceeded my expectations.

Rated 5 out of 5 by from Beautiful! I purchased a large 8ft wide picture window for my kitchen. When I first saw the window installed, it took my breath away. Bridget and Tahlia provided excellent service and Dan and Brian did a great job installing the window, on time and with a smile!
