Types of WindowsAbout GTS Windows & DoorsGTS Windows and Doors was incorporated in 1986. The installation is a very big part of the operation. This showroom is a Satellite office and the Sales Representative Chris Harnock looks after the Guelph day to day Sales and installations. A second showroom was added in Guelph in 1997. Donalee looks after the office and Kitchener showroom. David concentrates on the day-to-day operations of the company including Sales and Supervision of the installations. Currently GTS Windows is owned and operated by David Harnock and his wife Donalee. The original owner was Gordon Schnarr until his retirement in 1987, at which time his son Tom Schnarr took over the business. It is a family business, originally a subsidiary company of Schnarr Construction, which built custom homes and renovations in the early 1970's. Today people want to know who is going to install the product, what the warranty is and who is responsible for warranty issues.
