Lake Washington Windows & Doors is rated 4.8 out of 5 by 95.
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 Very happy with LW Windows and Doors all around We were somewhat concerned about replacing our windows because we have aluminum siding which we thought would make it somewhat of a more difficult job. We need not have been concerned. The installation crew was great and we are very happy with the job done.

Rated 5 out of 5 by from Our house is full of light! Our cloudy gable windows at the top of our vaulted ceiling have been replaced with crystal clear Milgard windows, flooding our foyer with light to brighten up the dark Seattle winter days.

Rated 5 out of 5 by from Great Experience We worked with Mike and finishing our order kept getting pushed under the rug. Once we finally placed the order, it was a quick turn around process. Not only were we able to just have one window replaced which was all we needed, it was a great price, great quality work and great to work with.

Rated 5 out of 5 by from New windows look great We had Lake Washington Windows put in our new Milgard windows and they look great. It is too soon to know about energy savings but I think there will be some. The guys that installed the window were great.

Rated 5 out of 5 by from Friendly professional service! D’Shane was very knowledgeable. He took measurements, explained options and got our windows ordered. It was nice to see that he also did the installation. Quick and professional service!

Rated 5 out of 5 by from this product is well constructed and user friendly this product (over-sized sliding glass patio door) is well-constructed and fits well into the opening - although the size of the door makes it quite heavy, the door/screen slide well and are easy to open/close/lock whuch makes the product very user friendly and helpful for the elderly or incapacitated
