Your Local, Family-Owned Window Company Serving Southeastern Pennsylvania

Keystone Window of Pennsylvania is a local, family-owned, family-operated window company serving Southeastern Pennsylvania. We offer top-quality vinyl windows that are custom-made to provide the best curb appeal and energy efficiency for your home.

It all began in 2003 when Rob and Cherie Mato needed new windows for their home. They invited several window and door companies to their house for estimates, but were turned off by the 2-3 hour, high-pressure sales pitches and constant dropping of prices to get them to “make a deal tonight.”

At that point, they realized their area needed an honest, upfront window and door company because consumers deserve to be treated better. The Matos, a local family from the Collegeville area, started Keystone Window of Pennsylvania in 2005 to be very different from the everyday high pressure/hard sell home improvement companies that existed.

Keystone Window of Pennsylvania has kept the promise of always providing upfront pricing — in 30 minutes or less — that would be the final price. To never haggle, negotiate, or disrespect the customer. To give the customer a great product at a fair price, professionally installed. We have never looked back, and are growing every year thanks to thousands of satisfied customers who refer us to their family and friends.
