"I highly recommend Clifton Contracting. The owner and all his employees are great to work with and did an excellent job installing my egress window. They even worked with me to take care of some other home to-do's on the fly. I would happily use them again."

"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."

"Outstanding service. Came same day to replace my windows. Did a very clean and thorough job. Most other companies refused to even offer the service of replacing glass in windows let alone charge a reasonable fee. I'm so glad that I found Glass and Window Solutions. Their team is clearly highly skilled. They made removal and replacement of the window glass look easy even though another contractor had failed miserably to accomplish this task without damaging my vinyl window frames!"

"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 had new glass installed in a patio door, a three window bay with floor to ceiling glass, and a front window. All were custom wood windows that were old. Metro did an outstanding job. They had a competitive quote. They were professional and friendly. They cleaned up after the work. My wife was happy. All good. High recommend."

"The Glass Smith installed windows in my upstairs master bathroom and main level laundry room. They provided excellent, professional, and honest service. Devin, Head Manager, was engaging, friendly, and efficient. He provided exceptional customer relationship management. Jermaine Science, Master Technician, is truly a master in his craft. He was thorough and yet efficient. He also caulked several windows and corrected flaws of a previous window installation company. Without any reservations, I recommend Jermaine for any window project."

Windows FAQs, answered by experts

Steel windows are durable and last a long time, but not in all weather conditions. If you live near the ocean, these windows might not be the best choice, as the saltwater breeze can corrode the metal. Steel windows are also more expensive than other types of windows. However, with that high price point comes a sleek, distinctive design that many homeowners find appealing, especially for modern decor. You can also restore steel windows to get a longer lifespan from them, so they can last longer than vinyl, aluminum, and even wood.

The best time to remove and restore old windows is during temperate weather. Late spring and the early onset of winter are ideal seasons. While summer has its challenges (e.g., bugs, heat, and dust), it’s also a good time to do restoration work. The worst time to restore old windows is during the winter, especially if it is particularly cold and snowy.

Because egress windows are meant for emergency exiting and entering, they need to be an accessible size. The smallest an egress window is allowed to be is 15 inches in width and height, with an opening of around 4 square feet.

Yes. Vinyl windows have a PVC frame that wraps around a glass panel that is usually made up of two thinner glass panels separated by an insulating, noise-absorbing airspace. Some vinyl windows are triple-glazed, with three insulating air panels within them. This glass helps keep your interior quiet from outside noise while its insulating qualities help your space stay cool in the summer and warm in the winter.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.
