In King, three vent configurations account for the majority of dryer-related fires: (1) flex-foil transition ducts over 8 ft, (2) any run over 25 ft with more than two 90° elbows, and (3) rooftop terminations without a proper backdraft damper. Cleaning + code-legal rebuild runs $189–$650. Same-week booking across King.
Ontario Building Code 6.3.4 caps a dryer duct at 7.5 m equivalent length (each 90° elbow counts as 1.2 m). Most $King townhouses and infill semis exceed that by design — the laundry is buried in a mid-house closet with a 30-ft run to the exterior wall. That's a lint trap by geometry.
Add flexible foil ("slinky") transition duct — technically illegal under CAN/CSA — and you get the exact setup behind ~2,900 dryer fires a year in North America (NFPA).
Different King building types drive different vent failures. Below: risk profile and typical fix per neighborhood.
Annually for single-family homes, every 6 months for townhouses with long runs, and every 3 months for shared-stack condo buildings.
You can vacuum the lint trap housing safely. Full duct cleaning requires a rotary brush kit and access to the roof or exterior termination — not a homeowner job in most King configurations.
