North York's pre-1965 housing stock was built almost entirely with galvanized steel supply pipes — a material that corrodes from the inside out over decades, gradually narrowing the interior bore until water pressure to upper floors drops to a trickle and hot water turns orange-brown. At this stage, section or full-home replacement is the only lasting fix.

Galvanized pipe replacement is among our most common North York calls, particularly in the Bathurst Manor and York University district bungalows. We replace galvanized with PEX-A (preferred for retrofit flexibility) or copper (for exposed runs near water heaters).

Poly-B pipe installed in 1980s–1990s North York homes is a second major pipe concern. North York's chloramine-treated Toronto water supply accelerates Poly-B degradation at brass fittings — we recommend full home assessment for any North York home built 1980–1998.

Heavy glacial clay till soil in Don Mills and Willowdale exerts ongoing pressure on buried pipe connections, accelerating joint failures in rigid galvanized and older cast-iron sections. The combination of soil movement, corrosion from inside, and hard Toronto water (7.3 gpg) creates multiple simultaneous stressors on aging pipe systems.

Many 1960s North York bungalows still carry their original 1-inch galvanized supply mains — a pipe diameter that was barely adequate for 1960s household demands and is completely inadequate for modern multi-bathroom homes. Upgrading to copper or PEX-A typically doubles water pressure to upper fixtures and eliminates the brown-water complaint that makes daily showering unpleasant.
