"Zen Windows advertises that they make things easy, and that they do. Zen windows doesn’t just make things easy, they have quality products, reasonable prices and exceptional service. We just had an entry door replaced and everyone we worked with was great. While they don’t push you into buying any products, they do go out of the way to help you make the right decisions. Everything went exactly as they told us, the installers were top notch and the finished product looks great. Without hesitation, we would highly recommend Zen Windows to anyone looking for doors or windows."

"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"I am very fussy and frequently critical, yet I have only the best things to say about Unicorp window replacement. The owner came to my home - on time - to explain all the options and costs for replacing my windows. It didn't feel like a sales pitch, but more like a discussion of what was best for my home. Unicorp is a local company and makes their own windows, so I knew if there was a problem, there would be someone nearby to call. My windows were installed on time and the crew was very professional. They are very hard workers; they didn't even take a lunch break. I was assured that my new windows would not let the cold air in, as my old windows did. I'll have to wait for winter to test this out, but I have confidence that since these windows were custom-made for me, they fit more tightly. It has been a pleasure to find a local company that has an excellent product, is honest, and reasonably priced."

"I would recommend this company to anyone needing glass repair. We had window glass replaced that had broken seals resulting in foggy windows. They were professional and got the job done right after the ordered glass arrived. I will use them again if needed."

"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."

Windows questions, answered by experts

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

Most homeowners prefer to service their windows during the spring or fall when temperatures are the most bearable, and having large openings in your wall won’t drastically increase your heating and cooling bills. However, while these seasons are the most convenient, you’ll also tend to pay more for window repair due to the increased demand. If you want to reduce labor costs, consider making window repairs in the off-seasons. Avoid waiting until the heart of winter to do repairs, though, as you could run into leaks and heat loss issues.

There are a few reasons your crank windows might not close. First, determine if your window crank is working properly and opening and closing the window when you turn it. If it’s not, the crank may need replacing, cleaning, or lubricating. Another reason your windows aren’t closing could be dirt and debris in the window hinges or sash. Finally, make sure your window lock operator is set in the unlocked position and isn’t blocking the window from fully closing. If you’re still having trouble closing your window, it may be worth consulting a local window contractor.

Picture windows last about 20 to 50 years, depending on the material, your location, and how well you maintain the windows over the years. Materials like vinyl and aluminum may not last as long, while fiberglass can last many years. Wood will last decades if you keep up with maintenance. Homes in areas with harsh weather throughout the year may cause windows to have shorter lifespans.
