"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

A window may fail because of age, defective mechanisms, or moisture. Depending on the issue, the window may be fixed with simple repairs. Otherwise, you’ll have to invest in replacing it. You can avoid damaged windows but keeping up with window maintenance.   

Picture windows last about 20 to 50 years, depending on the material, your location, and how well you maintain the windows over the years. Materials like vinyl and aluminum may not last as long, while fiberglass can last many years. Wood will last decades if you keep up with maintenance. Homes in areas with harsh weather throughout the year may cause windows to have shorter lifespans.

No, not every window has movable sashes. Many fixed or stationary windows that were intended only to provide views and sunlight still have inoperable sashes that allow them to match the rest of the windows in a home. These are called sash-set fixed windows. They are created by glazing a window into a sash that is secured to a frame.

The type of casement window you have depends on where the hinges are located, the number of sashes, the style, and how the windows open. Single casement windows are popular casement windows that use a handle or crank to open. If you have two casement windows side by side, you likely have double casement windows. 

Windows that swing inward can tip you off to having in-swing casement windows, while windows that open from the bottom and swing outwards are top-hinged. If you can open your windows by pushing them outwards like a door, you may have a type of push-out window.

It is legal to put bars on windows in most places, but it depends on the type of bars you choose and the regulations in your area. For example, there are building codes in Mississippi, California, and Texas that forbid the use of permanently closed burglar bars on windows due to concerns about people getting trapped inside during fires.
