Fiberglass Doors for Seattle, WA Homes

Embarq entry door on a home

The entry door to your home is more than just a door — it’s a statement piece. By purchasing your new entry door with Signature Window & Door Replacement, you’re choosing to work with a company that will help you find the right replacement and ensure it’s installed correctly. Every window and door we sell is custom-built for your home for the right fit, visually and structurally.

While there are appropriate applications for wood and steel doors, most Seattle-region homeowners benefit from investing in fiberglass entry doors. Fiberglass doors are beautiful, strong, and energy-efficient, and they can withstand the wild weather changes we experience in the Pacific Northwest.

Traditional wood doors warp over time in the wet Pacific Northwest winters. Fiberglass doors don’t warp, crack, or shrink with our area’s temperature changes. They’re low maintenance and can be cleaned with soap and water. ProVia fiberglass doors feature unparalleled solid construction for significant safety and reliability.

Fiberglass doors come in a variety of finishes, including wood grain. You can select wood grain textures like cherry, mahogany, or oak to gain the beautiful look of a wood door without long-term issues.

Signature Window & Door Replacement offers extensive fiberglass door options. Because every door is custom, we’ll work with you to design the exact door you want.

Revitalize your property with new fiberglass doors. Contact us now to schedule door replacement services in Seattle.

I cannot praise Signature highly enough. We hired them in 2012 to replace all of our windows and two sliding doors - the work was excellent and we love our Simonton windows. We just hired them again to rebuild our two-story entryway and install a Perva door and new windows. From the very thorough conversations with our salesperson, Vitaliy, to the scheduling with the office staff, to the actual installation - everything is as professional and high quality as you can find. We gathered quotes from three other companies but none of them went to any effort to truly lay out how the job would be accomplished. Photos show the old & new interior side, and the new exterior. Still needs painting but we're so happy!

After an extensive vetting process and comparing multiple options, I confidently chose Signature Windows & Doors for my home, and they absolutely delivered. The Marvin brand windows they installed are beautiful and of incredibly high quality—the craftsmanship speaks for itself. Beyond the great product, the installation process was truly exceptional. The crew was professional, precise, and made the entire project seamless from start to finish. I highly recommend them to anyone looking for top-tier windows and flawless execution. I had a fantastic experience with Signature Windows & Doors.

We called our project "The Window From Hell." It was a HUGE trapezoid window up high in a 2-story living room, and it needed to be replaced after its seal failed. I got bids, and was the most impressed with Danny L at Signature Windows. We had a tight deadline because the home was going on the market and access to the window, especially in the rain, was really challenging. Meeting the deadline, and the safety of the installers, were non-negotiable. Danny came out the very next day to measure the Window From Hell and, not only did he give me the best price, but his company was the only one that had all the scaffolding equipment readily available at no extra charge. The window arrived sooner than expected, and installation was quickly scheduled to meet the deadline. Then we hit a snag: some epic rain made the cedar roof too slippery for safe conditions. Brent and his crew of expert (and very brave) installers rigged up a safe way to haul this brand-new Mother of ALL Windows up to the second floor and install it using very long ladders, secure scaffolding, and harnesses. I think we had 4 or 5 installers for this job. It took all day to get the old Window From Hell out and the new Mother of All Windows installed. But what a job! Perfect caulk lines, perfect cleaning of the glass, perfect clean-up of the job site, indoors and out. Job done ON TIME, SAFELY, and at an excellent price. If Signature can handle my Window From Hell, I am very confident they can install ordinary double-hung windows that exceed your expectations for quality, price, timeliness, and workmanship. I highly recommend Signature Windows.

Everything from the initial consultation, regular updates on my order and installation was wonderful. The most recent installation was the third time I've had Signature replace old windows and I've been so pleased every time. They took the time to explain which windows needed replacement and provided options without any sales pressure. It's so nice to work with a company that believes in great customer service and offers quality products.

We have chosen to work with Danny and his team at Signature Window & Door twice now. We love the quality of the windows and the help they provide in the design process all the way to the finished installation. We put in a 15' folding door at our last home. It was a showstopper! Highly recommend them to bring your home back to life with beautiful windows that are built to last!

We bought a house that needed all new windows & sliding glass doors replaced. So we did our research and visited window replacement companies to see & touch different window & screen types. We decided to work with Signature Window primarily based on customer service as we received during the research & planning process with Office personnel (friendly, helpful, responsive) & Sales team (product knowledge, design assistance, open & honest).

1st Project (Aug 24) - 8 windows & 1 Sliding Door
2nd Project (Feb 25) - 1 ceiling to floor large window & 2 windows
Product of windows & door was excellent - we are extremely happy.

The customer service experience was superb. We worked with Sales Rep, Scheduler, Window Measuring Rep & Installers - all were friendly, open & honest, communicative, assisted with design & product knowledgeable. Installers did an awesome job with project cleanliness & kept busy all day long.

We are extremely satisfied with our overall experience with window replacement with Signature Windows 🥰
