How Long has The Window Source Been in Business?

The Window Source is an Industry Leader!

From the age of 15, our founder, Keith Kailian was setting sales calls for in-home improvement projects.  In 1975, Keith and his father, Norm Kailian, started a replacement window business in York, Pennsylvania. It grew to span the Mid-Atlantic Region and to be one of the most successful in the industry.

Over 40 years of working in the industry, Keith learned every aspect of the large-scale home improvement business including marketing, sales, branch management, and manufacturing.  In 1995 a replacement window manufacturing plant was acquired and The Window Source was launched in 2008.  Keith applies the skills learned over a lifetime in the industry to lead a streamlined business model that has made it one of the top replacement window companies in the nation. As a homeowner, you will notice The Window Source difference in the upfront pricing

“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
