Do bay windows add value to your home?

Yes. If you’re planning on selling your property, bay windows would be an excellent investment. In fact, a window seat is usually considered extra living space.

How long do bay windows last?

High-quality bay windows can be expected to last at least 20-25 years with proper care.

Bay window vs bow window – what’s the difference?

This is a commonly asked question, and the answer is simple. Bay windows are made using three windows, while bow windows are made using 4 or more windows, depending on the look you want. This also means that there’s a significant cost difference, with bay windows being cheaper.

How much do bay windows cost?

Bay windows aren’t expensive. You’ll find many affordable products by great brands. We would be happy to take you through our available options that fall within your budget, and help you choose something that’s right for your home.

Where can I buy bay windows?

Milgard and Andersen, two of the leading window manufacturers in North America, have some beautiful bay windows that you can take a look at. Milgard’s Tuscany Series, Ultra Series and Aluminum Series have gorgeous bay windows that offer different benefits, and Andersen’s 100 Series and E-Series offer environmentally-friendly, affordable and customizable windows. Lake Washington Windows and Doors is a certified installer of bay windows for both companies.

Seattle Bay and Bow Windows

If your home enjoys plenty of sunlight and a scenic view, bay and bow windows can instantly enhance its style and atmosphere. Bay windows are built with three windows, a large center picture window flanked by angled side panels that can open for ventilation. Bow windows include four or more equal-sized panels that form a gentle curve, creating a wider, better view. Both designs extend outward from your home to add depth, dimension, and natural light, transforming any room into a brighter, more inviting space.

Benefits of Getting Bay and Bow Windows

Bay and bow windows offer a variety of benefits that enhance your home’s comfort, style, and functionality.

Add usable space: Bay and bow windows extend beyond the wall to create extra room for seating, décor, or shelving, making small areas feel more open and functional.
Bring dimension to flat walls: Their projecting design adds shape and visual interest, giving living rooms, dining rooms, and kitchens a more dynamic architectural look.
Open up wider views: Multiple angled or curved panels expand your sightlines, providing broad, uninterrupted views that standard flat windows can’t match.
Brighten your home naturally: By capturing light from several directions, bay and bow windows fill your space with more daylight and create a warm, inviting atmosphere.
Improve airflow: When built with operable windows, they pull in fresh air from different angles, helping maintain a comfortable indoor environment.
Enhance exterior appeal: Their distinctive shape adds character to your home’s façade and creates a standout architectural feature that elevates curb appeal.
Support year-round comfort: Modern insulated frames and high-performance glass options help stabilize indoor temperatures and reduce heat loss.
Create a natural focal point: The interior alcove formed by a bay or bow window becomes a perfect place for a reading nook, dining spot, or decorative display.
Increase home value: Because they add space, style, and light, bay and bow windows are viewed as premium upgrades that can make your home more desirable to buyers.

							We just completed having 8 new windows installed by Lake Washington Windows and Doors. The entire process went very smoothly. The new Anlin windows are very nice quality windows - a big improvement over the builder grade windows being replaced. The warranty offered by the company is excellent as is their detailed attention to how the window is sealed to assure no leakage.The sales staff was patient while we collected information before we committed to the project. Subsequently, the communication was very good with regards to scheduling. They were patient and accommodative with respect to our availability. The installation team of Dmitri and Sergei were great. They were very respectful and neat when entering the house for the inside work. They did a very high quality job and the new windows and framing looks great. They were patient with all my questions and concerns. They were punctual, very hard workers, and it was a pleasure working with them. We are very pleased having chosen this company.

							Their staff, especially Jim Marowitz, are top notch. Very informative, upfront, and do not try to upsell you. When picking a contractor for a job it is hard to gauge honesty, but with Jim, he went out of his way to make sure you were happy. He told us what options were probably over the top and recommended what would work best, not what cost the most.

							My experience with Lake Washington Windows and Doors was exemplary from our salesman Michael to the installation process. Our installers Ricky, Joel, and Emilio were extremely courteous and competent. The detail on the caulking and cleanup were standard setting. Our interaction with the office team was equally above par with rapid callbacks. I am not surprised by the performance of this company as I did thorough research before making my decision. The windows we selected were a brand that I had not heard of until now, Anlin. I was originally going to buy fiberglass windows but the more I learned about the Anlin vinyl windows the more I was impressed. Be sure to consider this manufacturer. Overall a great experience from start to finish.

							Lake Washington Windows and Doors was outstanding in every way. Michael in sales was well informed without being high pressured. Our installers Ricky, Joel, and Emilio were communicative, competent, with a skill to work clean. The team put up plastic barriers floor to ceiling to minimize dust and debris. This attention to detail really impressed my wife. We were going to buy fiberglass windows but Michael suggested that we consider vinyl windows by Anlin. The more I researched Anlin the more I was impressed by their technology. I highly recommend you consider this manufacturer. Overall from start to finish our experience with this company was outstanding with no anxiety.

Bay and Bow Window FAQs

Are bay and bow windows energy efficient in Seattle’s climate?

Yes, modern bay and bow windows are highly energy efficient. With insulated frames, Low-E glass, and argon gas fills, they provide excellent thermal performance suited to Seattle’s climate.

Do bay and bow windows require special maintenance?

Maintenance depends on the frame material. Fiberglass frames (like Milgard Ultra) require virtually no maintenance beyond occasional cleaning. Vinyl frames (like Anlin Coronado) are also low-maintenance. The exterior roof or copper top of bay windows may need periodic inspection.

Can I customize the interior of my bay or bow window?

Absolutely. Many homeowners add a window seat board, shelving, or decorative trim to their bay window interior. The recessed space is perfect for a reading nook, plant display, or additional seating area.

What should I expect during installation?

Bay and bow window installation is more involved than standard window replacement. It typically involves structural support modifications and takes a full day or more. Our team handles all aspects of the installation including framing, insulation, and finishing. Learn more about our installation process.

Do bay and bow windows come with warranties?

Yes, all our bay and bow windows come with comprehensive manufacturer warranties. Additionally, our Leak Armor Lifetime Installation Guarantee covers the installation for as long as you own your home.
