A Message from Our CEO, Joe Mauceri

“I’ve been involved in some form of construction since I was a teenager. I’ve had a passion for windows since my time at a major manufacturer of vinyl windows. Through the years I’ve developed some wonderful business relationships with some terrific people. My relationship with the folks from Marvin Signature Collection has led to where I am today as the owner of one of the elite retailers on Long Island authorized to sell and install Replacement Windows and parts.”
