How to Choose a Company for Replacement Windows and Doors

Buying replacement windows and doors in Redmond, WA can be a stressful, overwhelming experience. It is such a large investment, and so many things could go wrong. You want to work with a company you can trust to help you find the right products within your budget and get the installation done right the first time. But how do you go about finding a reliable installation company? These tips will save you time, money, and exasperation.

Gather Referrals

Most homeowners only have to get replacement windows once, maybe twice in the lifetime. Because it is a rare occurrence you want to know as much as you can about the process. The first thing you can do is talk to neighbors, friends, and co-workers in the area. See if anyone has experience with replacement window companies. Ask what they liked and disliked about the process and the company they worked with. This will give you a feel for what to expect and provide insights for things you need to watch for when choosing an installation company.

Do Some Research

Once you have some basic information you can go online and start checking out companies. Before you get too involved find out where the companies are located and how long they have been in business. Working with a veteran company with a longstanding storefront has several advantages and limits your risk. You should also check a company’s reputation against the Better Business Bureau. See if that sets off any red flags. Once you have done your due diligence you can feel more confident moving forward with your list of companies.

Check for Licensing and Insurance

You want to make sure the contractors you find have licensing from the city or state and have proper insurance for their business. You can ask to see a company’s credentials, certifications, and insurance policy. That way, in case anything happens you are not liable.

Ask for a List of References

Most reliable window and door installations run neck and neck when it comes to pricing. But another way to compare is by asking for references. If the company has been in business for a while they should have a list of clients you can call. You can ask these customers about their experience with service, communication, deadlines, clean up—whatever you might have concerns about.

Schedule an Appointment and Get a Detailed Quote

Once you have narrowed the list to two or three window and door companies you should sit down with each one for a consultation. You can go over the products, pricing, procedures, and warranty. The more details you get in writing the easier it is to make comparisons and feel confident in your final decision.

You don’t need a high-pressure, fast talking salesmen with offers that are too good to be true. You need a reliable company with installers who know their products inside and out. They should also get training from the manufacturer on proper practices, and are there to make sure you receive the best service possible.

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 🥰
