5 Signs You Need Replacement Windows

Your windows play an important role in your home. They not only let in natural daylight and provide ventilation, but also protect your home, enhance its curb appeal, and improve energy efficiency. Deciding when to get replacement windows can be perplexing. And because getting wood, vinyl, aluminum, or fiberglass windows in Bellevue, WA is such a large investment, many homeowners put off the project as long as possible. If you are wondering when it is the right time for replacement windows in Bellevue, WA, these are some signs to watch for.

  1. Expensive Energy Bills

You probably have noticed your energy expenses go up during heating and cooling seasons, but have you also noticed a price increase from year to year? This could be a sign that your old windows are inefficient or leaking. Modern window manufacturers have stepped up when it comes to insulation. There are thermal breaks, insulation, double glazing, and low-e window technologies to help keep you comfortable and better insulate your home. Fiberglass windows are especially efficient and will hold up for years. No more throwing money out the window!

  1. Broken Windows

Shattered glass is a clear indicator that you need new windows. But what about inoperable windows? Or windows that stick? Most homeowners consider these simple inconveniences. The truth is, if your windows do not function properly, it puts you at risk. Test your windows every few months to make sure they operate smoothly. If they get stuck or don’t unlock, try cleaning the track and using a silicone spray for lubrication. If that doesn’t correct the problem, it might be time for new windows.

  1. Condensation

Have you ever tried to wipe fog off your windows only to discover it is sandwiched between the panes? This isn’t just a fluke. It means the seals on your windows have broken and the inert gas between the panes has slowly leaked out. The fog does more than just block your view. It also means your windows are not as efficient as they once were. There is no solution for this problem. Instead, you need replacement fiberglass windows.

  1. Rot

Speaking of moisture, in rain-riddled Bellevue, WA, the damp air can have a big impact on your windows. Especially old, wood windows. It can cause decay, mold, and rot. This isn’t a problem you can ignore. If your window frame is compromised, you might also have trouble with water dripping down into the walls. If you notice bubbling paint, yellow stains, or wallpaper that is peeling away—call window professionals as soon as possible.

  1. Outdated Window Style

Functionality isn’t everything. Many homeowners are simply tired of their old worn out windows and want to update the style of their home. Windows can go a long way as a home improvement project. Fiberglass windows are especially stylish because the thin frames can hold larger panes of glass and you can paint them any color you choose.

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 🥰
