Lake Washington Windows & Doors is rated 4.8 out of 5 by 119.
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 Great local company! I contacted Lake Washington Windows & Doors for a much-needed window replacement. Their consultant worked with us to find the right affordable options and their installers were meticulous, curious, and professional.

Rated 5 out of 5 by from Professional Service! We purchased 9 new double-pane, Milgard windows for our home from LWW&D. They installed the windows, as well. The service was professional and the product is great. Thank you!

Rated 5 out of 5 by from Love the Windows and Slider! We had 11 windows and a slider replaced and from beginning to end the process was a smooth one. The salesman who came out to do the estimate was no pressure and very knowledgeable. Jerry and Ricky, the professional installers, were great to work with. They kept us informed every step of the process. They covered everything in plastic in the room they were working in so there was no mess at all. They cleaned up the exterior every day. There was a small tile in the bathroom that came loose during removal of the window and Jerry drove to the hardware store and got supplies to fix it. The windows have made a huge difference in the noise level and retaining heat as it’s gotten colder. Lastly, they wore masks and were very aware of precautions needed due to COVID-19. Also, the project manager, Heather, was very easy to work with on the financial side. Windows have a 10 year warranty on them. We had other estimates done and chose to go with Lake Washington Windows and Doors. We would highly recommend them! We LOVE our new windows and door.

Rated 5 out of 5 by from Awesome customer service! "The customer comes first" was exemplified by every person I came into contact with at Lake Washington Windows & Doors.. Starting with the sales rep who came out and listened to what we were looking for and gave us honest feedback without trying to upsell us. During the ordering process I had a unique request which they were able to accommodate. They kept me apprised during the whole process from ordering to delivery; the office staff was wonderful. The installers came out and did an awesome can't tell the windows had been replaced (kudos to the technician that came out and measured so accurately). Once the installation was completed they did a walk through and caught a scratch on one of the windows (we missed seeing it). They immediately ordered a new window and scheduled a time to come back out. After it was all done the office contacted me to see if everything was to our satisfaction. Can't tell you how happy we are that we chose Lake Washington Windows & Doors after having met with three other companies.
