20 window, door, and garage-door shops. St. Catharines holds 12. Named shops include Garage Door Canada on Highway 20 in Smithville, Louwes Windows and Siding on King Street in Lincoln, Clemence Glass on Niagara Boulevard in Fort Erie, and The Window Experts in Hamilton.
Names and addresses come from public sources: the 2022 Niagara Employment Inventory, City of Hamilton open data (licensed garages), and OpenStreetMap. Phones and websites appear only when those sources already had them; a listing is not a licence — check STO, ESA, or TSSA yourself when the trade requires it. Featured placements are labelled advertising ($29/mo or $249/year), not rankings. Full detail.
