What Bothwell-Accurate does
Bothwell-Accurate is a privately held Canadian total building envelope solutions provider founded in 1927 and headquartered in Mississauga, Ontario. Operating under sole ownership of CEO George Vassallo since 2006, the company employs approximately 1,000 professionals across offices in Mississauga (Ontario) and Surrey (British Columbia), and has completed more than 70,000 projects since inception. It serves industrial, commercial, and institutional building owners, developers, and general contractors across the two provinces.
The company delivers five integrated service lines from a single provider: Roofing Systems (green roof, modified bitumen, single ply, hot rubber, built-up roofing, sheet metal), Waterproofing (below-grade foundation walls, traffic topping, epoxy, polyurea, curtain wall injections), Architectural Cladding (aluminum, insulated metal panels, zinc, copper, terracotta), Glazing (structural glass, curtain walls, skylights, solar control glazing, store fronts, added via a 2021 British Columbia acquisition and rolled into Ontario in 2024), and Maintenance & Repair (24/7 emergency leak response, inspections, re-roofing, lifecycle service). Notable technical work includes 70,000+ square feet of triple-insulated glass units with dual low-E coatings on The Hive Vancouver, the tallest seismic-resisting building in North America.
Revenue is generated through project-based lump-sum construction contracts for new builds and re-roofing, plus recurring maintenance and emergency service agreements. Distribution is direct enterprise field sales targeting developers, general contractors (e.g., Bird Construction, PCL Construction, Concert Properties, Reliance Construction), institutions (e.g., Toronto Western Hospital, UBC Museum of Anthropology), and property owners across Ontario and British Columbia. The company carries COR Certification and multiple safety awards, and supports its sales motion through content marketing (BA Broadcast), Instagram, athlete sponsorships, and earned media through construction industry awards.
