What are the Most Common Causes of Window Failure in Bellevue, WA?

Windows are an essential part of your home. They open to improve ventilation…they let in natural light…they protect your home against the elements and unwanted intruders…and they help keep your home warm in winter and cool in spring. But no windows last forever. Over time, the seals break down, the frames warp and fade, or the glass shatters. These are a few of the most common causes of window failure in Bellevue, WA:

  1. Poor Installation

One of the leading causes of premature window failure is a faulty installation. Some homeowners try their hand at DIY window replacement or hire a general contractor for the job. But window installation isn’t as straightforward as you might think. There are many details and intricacies you need you understand if you want to get the job done right. One mistake and you could render your new fiberglass windows completely useless. The leaks and damage from a poorly installed window could be disastrous. Don’t fall into this trap, no matter how handy you might be. It’s always best to leave all window installations in Bellevue, WA to the professionals.

  1. Accidental Damage

On television, it is usually an enthusiastic youth with a baseball that breaks a window, but accidents can happen for any variety of reasons. Maybe you tip over a piece of furniture or a rock flies out of the lawnmower and breaks the glass. This type of accidental damage is common and while you might be able to get the pane fixed, the window has been compromised. It will never perform as well as it did in the past unless you get the entire unit replaced.

  1. Improper Maintenance

Ideally, you should clean your windows once a week and perform general maintenance tasks once a month. This includes inspecting the glass and frames, cleaning everything, and lubricating the tracks and mechanisms. If you use the proper tools, this will help prolong the life of your windows. But using harsh chemicals, power washers, or abrasives to clean your windows will wear them out much faster and often result in window failure.

  1. High Moisture Levels

There is no shortage of rain and humidity in Bellevue, WA. As a result, your windows are more likely to fog, leak, and suffer from water damage. You will want to watch for signs of mold and moisture damage. It can show up in the form of discoloration, peeling paint, warping frames, or pooling water. It might not seem like much, but if left to fester, rot, mold, and damage could become dangerous and expensive to fix.

  1. Insects and Pests

Termites are terrible for wood windows. But other insects, rodents, and pests trying to gain access your home can also damage your windows. Look for signs of scratching, scraping, and dry rot.

  1. Regular Wear and Tear

With time and use, your windows start to break down. While there are some things you can do to lengthen the life of your windows, eventually you will need to replace them. Modern vinyl, aluminum, and especially fiberglass windows are built to last longer than ever before. Once you make the investment, you can expect your new windows to last anywhere from 20 to 30 more years, with proper maintenance.

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 🥰
