"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

Tinting your windows will make your house darker since it will prevent some sunlight from getting inside. While you can choose a window film that is on the lighter side, there will still be reduced sunlight. If natural light is important to you, tinted windows might not be the best choice for your home.

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.

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.

Yes, every window needs a lintel. The lintel is necessary for redistributing the load above the window to the walls around the window. Windows aren’t meant to support a load, so lintels are an important part of a window installation. If you go to replace your windows and discover there are no lintels, you may need a window company or structural engineer to install lintels for your new windows.

You should avoid using abrasive materials and harsh chemicals when cleaning windows. Abrasive tools like scrubbing pads, rough cloths, or steel wool can permanently scratch and damage the glass. Harsh chemical cleaners containing alcohol or ammonia can damage window treatments, frame materials, and special features like tinting. It is also best to use distilled or filtered water instead of hard water, which can leave spots or streaks. For best results, use a clean microfiber cloth to wash the glass and old black and white newspapers to dry it without leaving streaks.
