Window FAQs

When Do I Use Casement Windows

Casement windows are operated by opening them outward using a crank. With that in mind, casement windows are an ideal addition if you have a lot of space on your home’s exterior. We do not recommend installing casement windows that are close to a garage area or a space that has high foot traffic as this will disrupt their walking path. A few examples of these spaces include decks, balconies or your front porch. Casement windows are also a great option if you’re looking to improve your home’s energy efficiency since they allow more natural light in, as well as ventilation. Even more so than double hung windows.

Are they Safe?

Casement windows are one of your safest picks since they have an airtight seal and a multi-point locking system that serves as a deterrent against home intruders. It also serves as a great emergency window, allowing you to exit your home easily in case of an emergency. For instance, they’re used in basements where egress space is limited.

Are they Low Maintenance?

Andersen®  casement windows are low maintenance since they’re very easy to clean. They’re also available in a variety of styles, such as vinyl that looks brand new even across the years. In fact, they can be simply cleaned by applying warm, soapy water on them and wiping them off clean. It can also be cleaned from the inside by cranking your window open and removing the window screen.

"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!"
