What is a double-hung window?

The double-hung window is a vertical sliding window that has two sashes that operate vertically for ventilation from either the top or bottom of the window unit. Both sashes tilt in for safe and easy cleaning from inside the home. Balancers counter the weight of the sashes to provide easy operation and to allow the sashes to remain open in any position.

What is a single-hung window?

The single-hung window is a vertical sliding window that has a fixed top sash and a bottom operating sash that operates vertically for ventilation. The bottom sash can be remover for cleaning. Balancers counter the weight of the operating sash to provide easy operation and to allow the sashes to remain open in any position.

See What Our Customers Are Saying About Us

“The company to use if your needing window replacement, Fair pricing and honest fast work.”

Tom Reavis, GA

“Fantastic Company and true to their word! The crew was so professional and polite. We had our entire house of windows done and it only took 2 days. The quality of these windows are amazing and we couldn’t be happier! Don’t pay the high price that other companies want. This is the real deal!”

Jennifer Rochester, NH

“The Window Source of Tulsa was recommended to us. We received bids from three window replacement companies. Window source had the best product at the best price. The installation was on time and professional. We were kept informed through out the process. We are very pleased with the final product. About two weeks after the windows were installed I broke the outside pane of one window while mowing the yard. I contacted Window Source and told them what had happened, offering to pay for the replacement. They replaced the window free of charge. They are a pleasure to do business with.”

Alan McIntyre, OK

“Excellent service, product, and less than half the price of the other 2 estimates I had. Installer cleaned up after himself and was very professional.”

Ian Gollahon, OK

“Quality windows at an affordable price. Love our windows! Talked to several companies, but The Window Source offered top notch windows at the best price. Sales and installation crew were very nice, knowledgable and professional. They did a great job.”
