About Us

When I was twelve, I went to work with my father cleaning windows on weekends to help make ends meet. My father taught me the trade, the value of a dollar, and how to work hard.


In 1977, at the age of 18, while attending Duquesne University school of Music, I went to work for John Julius window cleaning as a part-time window cleaner. I worked my way up the ladder (so to speak) and by 1983 I had full ownership. I was then joined by my brother John, and together we proudly changed the name of the company to Liberatore Inc.


For more than 30 years, Liberatore Inc has been dedicated to offering an affordable, yet personalized and professional variety of services to our clientele.


After successfully completing the carpentry program at Connelly Trade School in Pittsburgh, we began installing quality replacement windows for Traco, the leading manufacturer of the window industry. We pride ourselves on customer satisfaction; expert services; knowledgeable, courteous staff; and we try harder to make sure every window cleaning or installation is done in a professional and timely manner.


To date, Liberatore Inc. has four full-time window cleaners/installers. We manage more than 1,200 accounts consisting of residential and commercial customers.


When you search for a contractor to clean your windows or install new windows, please consider us for your service contractor. We will work very hard for you.
