Hi-Lon Glass is a service company that specializes in the repair or replacement of all makes and models of windows and doors. We have been servicing the commercial/residential market since 1968. Over the years, Hi-Lon has developed relationships with a large network of suppliers. This enables us to obtain parts for windows and doors that other service companies do not readily have access to. As a result, Hi-Lon is often able to repair problems for a reasonable price whereas, many of our competitors can only replace entire units or systems.
