"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."

"Our sliding glass door was barely sliding – dragging would have been a more accurate word for it. Moses diagnosed the problem as more than just the need for new rollers, showed us where the track was excessively worn, obtained what was needed to repair the track rather than trying to replace it, and now our door rolls smoothly again. We are very pleased."

Windows questions, answered by experts

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

Yes, with modifications or the use of adapter kits for tricky placements.

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.

Yes. Thermal pane windows can be customized to fit a variety of different window sizes and dimensions. A contractor or manufacturer can usually offer custom sizing options based on your specific window requirements. You should consult with professionals who can assess your needs and provide the appropriate custom window solutions for your home.
