Windows and Doors Across Waterloo Region and Wellington County

GTS Windows & Doors has installed, replaced and repaired windows and doors since 1986 from a single shop at 47 Bridge Street East, in the old Bridgeport village on the north side of Kitchener. From there we cover the three cities and three rural townships of Waterloo Region, the City of Guelph, much of southern Wellington County and the town of Acton in Halton Hills.

Our customers include families replacing drafty original windows, landlords turning over rentals, builders and general contractors who need an installer they can rely on, and owners of shops, offices and industrial buildings. Every crew is licensed, insured and WSIB covered, we are a SAWDAC member, and each installation carries our 20-year parts and labour warranty whether the job is two blocks from the shop or out past Rockwood.

Our regular service radius is about 45 minutes of driving from Kitchener. For towns near the edge of that radius, we group on-site measures and installations by area and day, so a customer in Elora or Acton gets the same crew, the same products and the same scheduling care as someone in Waterloo.
