"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"Perfect Choice Exteriors was fantastic. They helped us find some specialty windows for a new addition to our home. We added a new bay window and an octagon window in the living room. I was surprised by all the options and their ability to make custom windows. Products were expensive but worth the cost!"

"Hired to replace 2 window screens on the second story of our home. Val found another one that needed replacing, and he did that one too, for no additional charge. He also fixed our kitchen light so that it stopped blinking when we first turned it on. Friendly, courteous, punctual and professional. Will be hiring again."

Windows FAQs, answered by experts

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.

Glass block windows offer several unique benefits over traditional windows, and they create a much more unique look. These specialty windows offer added privacy while allowing natural light into the space, which is why they’re a popular choice for bathroom features. They also provide increased security as glass blocks do not open unlike traditional windows. Plus, they provide increased energy efficiency, lowering energy costs and preventing drafts.

Soundproof windows can be energy efficient, depending on the window type and manufacturer. Overall, triple-pane windows are more energy efficient than double-pane windows. However, according to the U.S. Department of Energy, a window’s energy-efficiency level is determined by multiple factors, including the frame material, if there’s any low-emissivity (low-E) glass, and the addition of spacers.

Because bay windows are a combination of three windows, there are many options for how wide or tall they can be. That said, individual windows come in standard sizes, and you can use those as a guide for the width and height of your bay window.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.
