What makes Renewal by Andersen windows and doors the best?

Renewal by Andersen has devoted a full century to improving our craft. We’ve put that time to good use – our windows and doors offer more efficiency, beautiful, and innovative than ever:


Our patented material Fibrex® was invented by Renewal by Andersen because traditional window frames made of low-quality vinyl or wood simply weren’t good enough. Fibrex® combines the durability and strength of wood, with the low maintenance features of vinyl to create a truly superior frame material. And you can only find this amazing material when you have Renewal by Andersen install your replacement windows.



When your windows are built with Fibrex®, you will be able to enjoy reduced energy costs as well as extremely low maintenance for years to come. This is just one reason why we’ve become the number one provider of replacement windows in the Seattle area.


At Renewal by Andersen, we celebrate our customer’s uniqueness by providing them the ability to completely customize their windows to fit their style and needs. We accomplish this by offering  over 5 million different combinations of finishes, colors, hardware and grilles to create a truly custom display in your Seattle home.


We also completely custom build each and every window to fit your home perfectly. During your initial consultation, our technician will take precise measurements of your window openings. That is how we ensure every window will fit seamlessly into their opening, while also minimizing any loss of energy due to leakage. No other replacement window company can deliver like Renewal by Andersen can.

Unbeatable Warranty

We believe our customers shouldn’t be left out to dry when they have a faulty or defective window in their home. With our unbeatable warranty, our customers can enjoy peace of mind for decades when they trust Renewal by Andersen for their replacement window project. None of our competitors can come close to matching our warranty program. That should tell you how confident we are in our windows.
