"We just had Unicorp install new windows throughout our entire house. The window quality is excellent and the installation went very well. We were replacing 55 years old windows - and were very happy with the entire process, from selection, exterior color choices, and finally installation."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"I cannot say enough good things about FCB. Max bends over backwards to make sure the customer is completely satisfied. I’ve never had a more responsive and conscientious contractor. We had FCB replace all of our windows in 2022. We were so impressed by the quality work and price that we called them again to replace our storm door, front door, sidelights and shutters. Great experience. Highly recommend!"

Windows questions, answered by experts

Soundproof windows can’t completely block all noises, but they will significantly reduce sound from the road, sky, or your neighborhood’s weekend activities. Choose a soundproof window with an STC rating of at least 45 to block bass tones or loud conversations. Laminated glass windows can reduce noise by 75%. You can also add noise-reducing curtains to further muffle loud noises.

The most common types of window frames include frame and sash, metal or aluminum frames, composite frames, fiberglass frames, vinyl frames, wood frames, glass or glazed frames, and insulated frames. Frames can also be categorized by operating types, such as awning frames, single/double-sliding frames, fixed frames, casement frames, and single/double-hung frames.

Glazing is always done from the outside of the window, while the inside doesn’t require any glazing. This is because the main purpose of glazing is to create a weather-tight seal where the glass meets the frame, protecting against drafts and moisture. Since the exterior is exposed to the elements, that’s the side that needs the weatherproofing.

Mulled windows are often more expensive than standalone windows. However, this is mostly because mulled windows tend to be larger than standard windows, meaning they require more materials and labor to manufacture and install, both of which drive up the cost. If mulled windows take up the same square footage as separate windows, they should cost about the same unless you need to reinforce your exterior wall to support the larger wall opening.

Shatter-resistant glass will ensure that even with a high impact, the glass of your window panes is less likely to break. If you’re looking for a more low-cost way to prevent vandalism, the most traditional answer would be to board up windows with a strong plywood sheet. Adding security cameras is also a surefire way to ward off potential vandalism.
