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 Quick professional installation We changed the type of 3 identical windows in one second floor room. The replacement was completed quickly and there was no cleanup or painting needed when the job was finished. We have had Milgard windows for over 20 years and would recommend them for any application.

Rated 4 out of 5 by from Great finished product and customer service. We love our new windows and the customer service was great throughout the long time it took from start to finish. Our older brick home was not easy for the crew to work on; one of the large picture windows they had to break out the glass with hammers, and during the demolition there was damage to our walls and window sills, and on the last day of the scheduled install the crew was there until 9 pm in order to finish the job! LWWD did have other specialists come back to the house to repair the drywall, sill and tile damage. We also had screens that were either missing with the original order or defective. These were finally replaced/repaired as well. The whole process from order to final finish took 4 months! Throughout the entire process all of the staff we spoke to or encountered were very courteous and helpful. If we were to replace additional windows I would demand to have their most experienced crew for the job; our old brick house and old heavy aluminum framed windows were too much for the crew they sent out. I left out some details of the last-day install but suffice it to say it was an ordeal for us as well as the crew. But all of the installation issues aside, we love our final product.

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.
