Poly-B in Richmond Hill homes
Polybutylene plumbing was commonly installed in Richmond Hill homes built between 1978 and 1998. If your home was constructed during this period, there's a possibility it contains poly-B pipes. Many insurance companies in Ontario now have specific policies regarding polybutylene plumbing, including potential surcharges or requirements for replacement. Learn more about poly-B →
Richmond Hill’s housing boom straddled poly-B’s final years. In the 2021 Census, 12,175 occupied dwellings date from 1981–1990 and 15,915 from 1991–2000, the town’s largest single period, making 28,090 homes or 40.5% of 69,315. Only about 15% of the town’s dwellings are older than that.
Richmond Hill is in York Region, which buys part of its water supply from the City of Toronto’s system (Toronto drinking water report). Owners of condominium townhouses should check their corporation’s declaration and by-laws before arranging a repipe, because those documents can change who is responsible for repairs (Condominium Authority of Ontario). Anyone practising plumbing in Ontario must appear on the Skilled Trades Ontario public register (Skilled Trades Ontario). The Toronto & GTA guide ranks Richmond Hill against its neighbours.
