"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."

"We had them clean the inside/outside/screens and sills, it was night and day how much better we could see afterwards. I didn't realize how dirty all of our windows were. The used just water on the windows too, I was shocked that no streaks were present afterwards. I will be looking to do this more often in the future and would not hesitate to use Virginia Window Cleaners again."

"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

Storm windows provide several key benefits. They offer improved insulation and soundproofing, which adds comfort to your home by regulating internal temperatures and blocking external elements. Storm windows also help reduce energy costs by preventing cold or hot air from getting inside. Additionally, they can protect the primary glass in your windows against weather damage.

On average, bay windows are three times as expensive as a standard double-hung window, so up-front cost is a major drawback. They also let in more natural light than most other types of windows, which can be a positive thing, but it can also lead to more aggressive fading and UV damage to furniture and flooring. Larger windows allow for more heat transfer, so bay windows tend to be less energy-efficient due to their size. Finally, window treatments for bay windows can be more challenging to find, and they’re more expensive than those you’d place over standard-sized windows.

Most manufacturers have their name imprinted somewhere on the window, such as the spacer bar, hardware, or frame. Other manufacturers will include an identification number printed on the glass itself. If you’re unable to find either of these, then your window was manufactured locally (oftentimes called a “shop window”). 

With a manufacturer name (or even better, the identification number) you can attempt to research the information to find out when the product was made. Keep in mind this won’t tell you when the window was installed on your home, but can get you close.

Most properly installed and maintained windows last between 15 and 20 years. Fiberglass windows last much longer than your average window. Since they don’t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years.

Window cleaning depends on how the cleaning service defines their deep cleaning tasks, so pay attention to the details. You certainly should make sure window cleaning is included in the package. Some services will include it as an add-on, so you may have to pay extra. Find out if the cleaning includes interior windows only, or interior and exterior windows. Exterior windows may cost more.
