Things to Consider Before Buying Bay Windows

Bay windows can increase your property value. They add extra square footage to your home, not to mention improving the natural lighting inside and making it seem more spacious. However, to make the most of a bay window, you’ll need to take into account a few factors before installing one.

The Size of the Window 

As mentioned earlier, one of the most attractive features of bay windows is the extra space and the natural lighting they provide so it would be a good idea to maximize these as much as possible. Plus, a bigger window can give a better view.

Keep in mind that heat from the sun or the cold from the outside can easily enter your home through a wide glass pane. To lower your power costs and maximize your returns on investment, we recommend installing energy-efficient windows.

The Type of Sash 

You’ll have a lot of freedom when it comes to picking a sash for your window; it’s mostly just a matter of preference. As a general rule, it’d be better if the sashes match the other windows in your home, but there are exceptions. For example, a casement sash would be better suited to taller, narrower bay windows while a double-hung sash would be a better fit for shorter windows.

Structural Support for the Window 

Bay windows protrude out from your home, which is why installing them requires a lot of modifications to the structure. For structural support, you can install either braces or support cables. The former provides support from below the window while the latter provides it from above. If you’re particular about your curb appeal, we recommend choosing the latter; support cables are hidden in the window frame.

Like we mentioned earlier, bay windows are difficult to install so you need to make sure your installer is qualified. You can vet them faster by checking their certifications.

Reviews

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
