I, Rob Mato, and my wife Cherie, co-own Keystone Window of Pennsylvania. In 2010 We sold and installed over 6,500 vinyl replacement windows. In other words, approximately 812 families entrusted us with fulfilling their window needs. No matter how you slice it, that’s a lot of houses!
We attribute our success to exemplifying integrity, being honest with our customers, giving exceptional service, and, of course, a lot of hard work. At Keystone, we advertise and sell only Energy Star certified products because our customers demanded a better insulated window. Our goal is to sell the best replacement window program in the industry at a fair price. That philosophy is almost unheard of in this business. Most companies either offer a low price and build price up with hidden costs, or start extremely high and discount down until you believe they’re offering a miraculous deal. At that point, you have no idea what your buying or whether it’s really a good deal.
We believe offering top quality vinyl windows, and telling our customers the total cost up front builds a solid infrastructure that will keep us in business for years to come. We only partner with high quality manufacturers because they agree with and follow our up-front philosophy, and they develop and build some of the best replacement windows in the industry.
We hope you will compare our window specifications and performance standards to our competitors. You will not find a better combination of features and benefits, along with a lifetime warranty, for less.
Keystone Windows currently serves Berks, Bucks, Chester, Delaware, Montgomery, Lehigh and Philadelphia counties.
