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

Armed with more than 30 years of verifiable success in areas of customer service, sales operations, business development, marketing, and communication, Ralph is the Vice President of Sales and Operations. Once you have had the pleasure of meeting Ralph, it is quick to see that he is approachable, well presented, and able to contribute immensely toward the success of The Window Source brand.

Our high standards for selection and conduct protect the integrity and value of our national brand.  The Window Source offers homeowners a very competitive price without all of the sales gimmicks typically used in the industry.
