"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

Not every home needs window capping. Whether or not you need to cap your windows depends on your climate and window frame materials. Wooden windows should have window capping if moisture is a problem. Arid climates like the Southwest may not need window capping due to low rainfall and low humidity.

In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. 

At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.

One of the best professional cleaning solutions that won’t leave streaks is one gallon of distilled or bottled water mixed with 2 to 4 teaspoons of dish soap. Apply using a sponge in a figure-eight motion, and then use a squeegee to remove the majority of the water and soap. You can finish drying with a piece of old black-and-white newspaper to remove any residue for a streak-free clean every time.

Bow windows need support because they are large and extend out from the exterior wall of the home. Bow windows may extend 1 foot to several feet from the outside of the home, so you’ll need to provide additional support to handle this weight. A window contractor will be able to provide the proper amount of support for your new bow window.

The key difference between a hung window and an awning window is that hung windows (including single-hung and double-hung versions) slide vertically to open and close. In contrast, awning windows have a hinge at the top and open outward at an angle. You can use both types of windows throughout your home, but awning windows are best suited for kitchens and bathrooms.
