What to Consider Before Choosing Replacement Windows and Doors for Your Home

Replacing old windows and doors is a smart decision, but that doesn’t make it an easy one. The market is saturated with options and the process can be complicated. With so many advancements and styles, you can quickly lose track of what you need and what you want for your home. And because it is such a large investment, you don’t want to make the wrong choice. So here are the top things to consider when you shop for replacement windows and doors in Sammamish, WA.

Consider Architecture, Orientation, and Landscaping

First thing, you need to consider what you have to work with. Is your home style traditional or more modern? Knowing this will help you decide which window and doors styles will complement the aesthetic. Where are your windows and doors located in relation to the patterns of the sun? This gives insight on how to capitalize on daylight. Do you have trees with eaves and overhangs to shade windows on the south and west facing sides? This information can help you make decisions about energy efficiency and low-e technology. Considering these factors will make all other decisions about new windows and doors less about guesswork and more about strategy.

Understand Energy Efficiency

Knowing how to read energy labels is the next step. It is the only way to get a direct comparison on the energy performance of different products. The U-value tells you how well a window prevents heat transfer from inside to outside. The Solar Heat Gain Coefficient shows how well the window blocks out unwanted heat from the sun. Air leakage ratings tell you how much air flows through the small joints and cracks in a window. And the condensation resistance relates the window’s ability to resist fogging. Every size and configuration will have unique energy ratings.

Compare Window and Door Materials

Each window and door material functions and ages differently. Vinyl frames are more weather resistant and affordable, but come with bulkier frames, fewer color options, and a shorter lifespan. Aluminum is strong and can hold more glass on thinner frames, but it is not as durable or energy efficient. Wood windows offer unmatched beauty and natural insulation, but are expensive and require a lot more maintenance. Fiberglass windows are durable, efficient, and long-lasting, but they are also some of the most expensive options on the market.

Don’t Forget Safety

Keeping your property and family safe is another top priority to keep in mind. Laminated glass is one technology you do not want to overlook. It not only makes windows more impact resistant, but also prevents the glass from shattering into large, dangerous shards. You also have to consider the operation of certain windows and doors on the second level of your home and if opening them could make it unsafe for children.

Know the Convenience Features

Last, but not least, what about popular add-ons? You can get a tinted glass to reduce unwanted glare. You can get tilt-in sashes for easier cleaning and maintenance. You can get low-e coatings to reduce heat gains or losses. You can get upgraded lock-sets. These technologies rank differently depending on your personal wants and needs.

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 🥰
