GTS Windows and Doors was incorporated in 1986. It is a family business, originally a subsidiary company of Schnarr Construction, which built custom homes and renovations in the early 1970’s. The original owner was Gordon Schnarr until his retirement in 1987, at which time his son Tom Schnarr took over the business. Currently GTS Windows is owned and operated by David Harnock and his wife Donalee.
David concentrates on the day-to-day operations of the company including Sales and Supervision of the installations. Donalee looks after the office and Kitchener showroom. A second showroom was added in Guelph in 1997. This showroom is a Satellite office and the Sales Representative Chris Harnock looks after the Guelph day to day Sales and installations.
The installation is a very big part of the operation. Today people want to know who is going to install the product, what the warranty is and who is responsible for warranty issues. Many companies offer Lifetime Warranty’s but have not been in business long enough to back it up. Our company has been in business for 28 years and we stand behind our products. We have been in business long enough to back up the 20 year warranty we offer and so have our suppliers
GTS Windows and Doors Kitchener Showroom is located at 405 Nyberg Street, 519-743-5050. The Guelph Showroom is located at 403 Woodlawn Road West, 519-822-2509. We recommend you call first before going to the Guelph Showroom as the Sales Rep is not always there. The Kitchener Showroom is open all day.
GTS Windows and Doors does not sub-contract out the installations, unlike many of their competitors, especially the big box stores. Our qualified installers have been with us for over 25 years. Over 90% of everything GTS sells is installed. The majority of their business comes from residential homeowners wanting to upgrade or improve their home. Our clients want to deal with one company and one person that will look after everything for them. We need to remain diversified enough to make it a one stop shopping experience for the client. For this reason, GTS does not consider the big box stores competitors, as they can’t offer the same service and supervision you get from a company that specializes in one area like GTS Windows and Doors.
