"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

Look for stickers at the top or inside of the frame, like in the tracks when the window is open. Some brands also stamp their name onto the frame itself or place it between the panes of glass, although this is less common. If you can’t find the info on the window itself, consider asking your neighbors or HOA.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

Yes, most manufacturers and contractors offer warranties covering materials and labor. It is important to confirm the specific terms of the warranty before purchasing.

On average, hurricane windows last between 20 and 30 years. But some windows only last 10 years, while others can last 50 years or longer. Vinyl hurricane windows have a shorter lifespan than aluminum, so invest in high-quality hurricane windows and properly maintain them to get the most out of your investment. 

Yes, storm windows should be tempered. According to the International Association of Certified Home Inspectors, tempered glass is stronger and can withstand temperatures higher than laminated glass. Tempered glass is important for storm windows because it protects against outside elements and household accidents by not producing sharp, jagged pieces when it breaks or shatters.
