Ontario Trough Pros was founded as an extension of Ontario Outbuilding. We offer professional installation and repair of Eavestrough, Soffit & Fascia, and Gutter Guards. We are proudly locally owned and operated - We install what we sell and don't use subcontractors, and because there's no middleman you get savings of 30-40% on average! Operating out of Dunnville, Ontario, we are proud to serve Haldimand, Niagara, Hamilton, Brant, and Norfolk.
