Why Should You Replace Your Windows NOW?

If your windows are 10 years old or older, they’re probably stealing more money out of your pocket than the IRS on a bad day.

According to the EPA, ENERGY STAR labeled windows are twice as efficient as the average window built just 10 years ago.  And 40-50% of a home’s energy cost is directly related to the efficiency – or inefficiency – of its windows.

From a strict energy efficiency view, windows are a bad idea.  If you want the most energy efficient home, insulate it well and skip the windows.  (We can’t promise good air quality, though.  Or, you know, light.)

Windows are a vital part of a safe, healthy home; no one would consider not using them.  But here’s the harsh reality: If your windows are a decade old or older, you’re throwing money out the window.  (Yes, the pun was intended.)

Technology is changing rapidly.  It’s true for Microsoft Windows. It’s true for the windows in your home.  (One could argue that home window technology is constantly improving, unlike the move from Windows 7 to Windows 10.  But that is neither here nor there.)  You’ve upgraded Windows on your computer.  Now it’s time for a stress-reducing upgrade: your home windows.  Improve your home’s appearance and energy efficiency, while lowering your utility bills.

5 Reasons You Should Replace Your Windows Now

Energy Efficiency & Saving Money

Ask most people looking for replacement windows in Seattle, and they’ll tell you it’s because their house doesn’t feel comfortable.  Homes become unbearably hot in the summer.  People spend a lot of money on insulating blinds that block sunlight – and foster mold growth by trapping cold air between the window and blinds.  That’s like treating cancer with an aspirin!  The real illness is your old windows.

Today’s modern window technology wasn’t available even five years ago.  Between low-emissivity glass to Infinity From Marvin® fiberglass window’s exclusive patented Ultrex Fiberglass, today’s windows are an excellent investment.

Signature Window & Door Replacement is the Puget Sound region’s exclusive dealer for Infinity From Marvin® fiberglass windows.  That puts us in the unique position to offer the highest quality windows on the market.  You’ll save significantly on heating and cooling costs and be more comfortable year-round.

Virtually Maintenance Free

Infinity From Marvin® fiberglass windows require little to no routine maintenance.  You just need to clean them periodically.  (Window technology has come a long way, but they’re still not self-cleaning.)

Infinity From Marvin® fiberglass windows don’t have to be scraped, sanded, taped, primed, painted, or repainted.  A specialty co-extruded coating is applied at the factory which won’t peel, flake, or blister.  This is especially relevant for Seattle homeowners.  Our invigorating coastal air is salt-laden and wreaks havoc on inferior windows.  In fact, some replacement windows require you to clean the frames with mineral spirits in order to remove salt deposits.  Then, you have to apply car wax to the frames to help prevent additional deposits.  We assume that’s not how you prefer to spend your free time.

Easy to Clean

Cleaning older windows is a chore.  Especially here in the Pacific Northwest.  It takes at least 20 minutes to clean one wooden window properly inside and out.  If you have a lot of windows, that becomes an all-day chore.  If you have storm windows, you have to take those down and then replace them in order to clean your windows.  And if you have a two-story home, you’re spending a lot of time cleaning – while standing on a ladder!  That makes the task potentially dangerous, as well as time-consuming.

Infinity From Marvin® fiberglass windows have a solution to this issue!  Our double-hung replacement windows have a concealed release button that allows the sashes to be tilted inward.  Casement windows have the “easy clean” hinge system.  Gliding windows have a release for sash removal.  This means that your windows can be completely cleaned on the spot, inside and outside.  No going outside. No ladder required.

Because of the increased overall efficiency of Infinity From Marvin® replacement windows, you don’t need exterior storm windows anymore.  Which means you can say goodbye to the frustration of removing and reinstalling them every time you clean.

New Windows Make Your Home Beautiful

If you’re going to the trouble of replacing your windows, you might as well make sure they’re gorgeous.  When building a home, a contractor’s mentality is often cost, rather than aesthetics.

Generally, homes built within the last 60 years have window styles that do not enhance the beauty of your home.  Signature Window & Door Replacement design consultants are experts at transforming your home with beautiful new windows!  We offer windows with sleek, thin lines for contemporary homes.  They will enhance the appearance your home while complimenting its style.

Homes older than 60 years often have beautiful windows.  And you don’t want to lose that beauty by replacing them with contemporary windows.  We have traditional-look window solutions with options that include divided lite grilles and even applied leading.  From complete replacement windows to inserts that are built to coexist seamlessly with your existing frames, we have the perfect window for your older home.

We can even reframe a wall to add a door or bigger window to enhance your views.

Increased Resale Value

You invest in home improvements with the expectation that you’ll receive a return on your investment (ROI).  This is particularly true in the unique Seattle housing market.  Not all investments pay off.  However, according to Remodeling Magazine, you can expect a return of over 75% when upgrading your windows.  Couple a 75% ROI with the money you’ll save on your energy bill and you can see how upgrading your windows with modern, high-quality windows with Signature Window & Door Replacement makes sense.

One More Reason to Choose Signature

By picking the right windows, you’ll save a significant amount of time and money while giving your home a fresh, updated look.

But regardless of what type of window you choose, the window is only as good as its installation.  Over 80% of a window installation occurs behind the walls – where you can’t see it.

It’s easy to hide marginal work or outright installation errors.  The Pacific Northwest winters are particularly unforgiving of installation problems.  And you won’t realize it’s a problem until it’s a really bad problem.  If water gets behind your window, it will result in water damage, mold, and rot.

Window failure can cost thousands of dollars in maintenance or replacement costs.

Even a mistake as little as ordering a window 1/32nd of an inch off the correct measurement can result in disaster.  At Signature, we use installation craftsman.  Our installers are AAMA-certified, which means they have obtained the highest level of training and certification available.  They are also factory-trained, which means they’ve undergone manufacturer training in the proper installation of the specific windows and doors we carry.

Our installers take pride in their work.  We will install your windows the right way.  We are so confident that we’ll install your windows correctly, we offer the Signature Installation Warranty on every window and door we sell. That means that for as long as you own your home, you’re covered for materials, labor, and glass breakage on every window and door installation.

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 🥰
