"I used H&F exteriors to redo the complete outside of my home. From top to bottom. My windows were the original windows to the home, now that it is summer time, my AC Unit barely runs, no where near to what it use to. From the window installers, to the guys on the roof during the hot day, and the siding guys. The entire team did a great job. I worked with Jill and she was easy to work with. Highly recommended."

Windows questions, answered by experts

The average lifespan for a casement window is around 20 years, but some higher-end casement windows with more durable frame materials can last up to around 40 years before you need to replace them. You’ll need to carry out routine maintenance and window cleaning—and, on occasion, casement window restoration—to extend the lifespan of your casement windows. But they tend to wear more slowly than windows with sliding sashes because the weatherstripping sees minimal friction.

Casement windows can either be left or right opening, and every window manufacturer makes both so that you can choose which works best for your space. In many cases, you’ll want one left-opening and one right-opening casement window to sit on either side of a picture window or to act as the side panels in a bay window. Just remember that the direction is described from the curb. An FCL (from the curb left) hinges out to the left if you’re looking at the exterior of your home, and an FCR (from the curb right) hinges out to the right.

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.

Yes, caulking windows is worth it. Because moisture and air leaks are big sources of common window problems, caulking can be an inexpensive and easy way to eliminate both water and air from getting in. 

The rough opening refers to the framed space in the wall where the window will be placed. That means the full size of the space will be filled with both glass and frame once the new window is installed. For a standard window, a rough opening adds 1/2 inch to 3/4 inch to both the length and width.
