Mississauga's houses range from the older lots in Port Credit, Clarkson and Lorne Park, many with masonry chimneys over wood fireplaces, to the 1970s to 1990s subdivisions of Erin Mills and Meadowvale, where a brick chimney often carries a fireplace plus a furnace or water heater flue.
The most common calls we get from Mississauga are sweeps before the burning season, WETT inspections when a house changes hands or insurers, and liners after a furnace upgrade leaves the water heater venting alone into the old chimney.
What we see in Mississauga
- Houses built from the 1970s to the 1990s often have one chimney carrying both a fireplace flue and a furnace or water heater flue.
- Lakeside lots in Port Credit and Clarkson get more wind-driven rain on the chimney crown.
- If you switched to a high-efficiency furnace, ask us to check the water heater's flue.
