STAY AWAY FROM THIS COMPANY.In 2010, Rob Mato came to our house as the owner and salesman for Window World of Philadelphia.
He gave us the same pitch he has on his new website that as the owner he could personally guarentee the product and the work. We purchased windows, siding, and doors from him. In March 2012, a piece of our siding blew off the house. When i contacted him, he told me he lost his Widow World franchise (Now I Can See Why) and that he was not responsible for any warranty.
I reminded him that he said he personally guarenteed his products and work, and since he had a new window company he should honor his word. He told to contact the new locale Window World, "Window World of the Tri State Area" and gave me their phone number off the top of his head. (How strange that he knew the number) I contacted them and spoke to the manager, Mr. Connelly.
I explained my situation to him and he told me that Window World would honor all product warranties but installation warranties with Window World have always been for 1 year. Some how he sensed my frustration and offered to have someone come to my home and put my siding back on the house.
I am now telling everyone I know to use Window World, and telling them to stay away from Keystone Windows.
Keystone new motto is "TRUST BUILT INTO EVERY JOB" You can trust that they will take your money and pass the buck to the next company to warranty their jobs after they close down.and open another company in a few years.
