Services FAQs

What about the garage and interior doors?

For the moment, we’re limiting our door services to entry and patio doors only. However, we can make professional recommendations if you need a garage and/or interior door service.

Do you provide window and door repair services?

We do not provide repair services, however, we can recommend some reliable repair technicians upon request.

Are you able to replace the glass panes of my wooden windows?

Our specialty is the installation of complete window systems (frame + panels). Glass replacement is a specialized skill provided by many other professionals in the Seattle area. However, we’d be happy to point you in the right direction if you prefer glass replacement over installing newer, more efficient window systems.

What areas do you service?

Lake Washington Windows and Doors is proud to serve the entire Greater Seattle area & King County (not including Vashon Island) along with Pierce and South Snohomish County. If you live within our service area, please don’t hesitate to contact us to discuss your replacement needs.

Do you require a minimum number of units per order? 

Currently, there is no minimum requirement for the number of units per order! Whether you want to replace a single window or a hundred windows, we’re here to help you get the job done.

Do you install new construction windows? 

We’re currently focusing our efforts on providing replacement windows only. The reason behind this is the difference in quality and structure of replacement windows vs. new construction windows. In fact, it’s often worth replacing new construction windows with retrofit windows to increase energy efficiency and durability. however, our doors can be installed at any point during your home’s lifetime. Reach out to our customer service team to discuss your circumstances.

What kind of warranty do you offer?

The beauty of working with the top window manufacturers in the industry is the support you can expect before, during, and after installation. Both Milgard and Andersen offer limited lifetime warranties. However, the likelihood that you’ll need to take advantage of these warranties is low.

Coverage Area:

  • Greater Seattle Area & King County (not including Vashon Island)
