Bay Windows

What Are Bay Windows?

A bay window is a style of window that protrudes out from the face of the structure, and they’re typically designed by combining three or more individual windows. This type of window adds architectural complexity to a building while also allowing for more interior space. The term bay window is broad and refers to many different window styles that have evolved over the years. In modern home design, the typical bay will have a large picture window at the center with either thinner picture windows on the sides for a fixed bay or casement or hung windows that open.

Many Benefits of Bay Windows

Bay windows add to curb appeal through their intricate designs and the contrast they provide. They add real value to a home as well with the typical return on investment being around 75%. There are many design options too as you can mix and match different window styles. A bay window provides intrinsic value for your interior as well, including ample sunlight and, if you opt for windows that open, ventilation. It will also give you a great view and allow for many interior design options.

Signs You Need New Bay Windows

Age is the top consideration because if you replace bay windows proactively, you’ll avoid the most common issues, including excess moisture and draftiness. Those are the two biggest problems to watch for as water getting in can quickly lead to bigger repair costs, and draftiness will undermine your home’s energy efficiency and cause your heating and cooling costs to rise. You should also replace a window that has non-superficial damage to either the frame or glass or is difficult to open, close, or secure.

Differences Between Bay and Bow Windows

Bay windows are typically made up of three or more windows whereas bow windows are usually made of five or more, but the biggest difference really comes down to the curvature. The design of a bay window will generally accentuate its outward angles. Bow windows are more curved, and the more individual windows they comprise, the smoother that curve can be. Bay and bow windows are chosen for similar purposes, but a bow can allow for more natural light and make a room seem larger than it is.

How we install your new windows

Each old window comes out with its frame, and the new one is built to the measurements of your opening. Before it goes in, we seal the opening with our Leak Shield system. That means a flashing membrane over the rough opening, butyl tape at every seam and flange, low-expansion foam in the gap between frame and wall, and a final exterior seal.

Leak Shield comes with every installation at no extra cost, and we back every installation we perform with our lifetime Leak Shield Guarantee.

We will never leave the job without ensuring you have the highest quality windows installed properly and your home is left spotless. We take pride in our work and respect your space, aiming to leave behind one of the cleanest job sites you’ve ever seen.

“Replacing my parents’ original builder-grade windows in their 25+ year old home was one of the best investments they’ve made… They’ve already noticed lower electric bills, less outside noise, and a cooler, more comfortable home that’s much easier to keep at a consistent temperature.”
