Plumbing in Markham homes
Heritage homes in Unionville and Markham Village have old plumbing hidden behind preserved facades, often with crawlspaces and fieldstone foundations. Subdivisions from the 1980s carry copper supply and ABS drains now needing their first big replacements. Newer communities often have rear-lane townhouses with compact mechanical rooms.
Common calls we take here
- Water heater replacement in tight mechanical rooms
- Bathroom renovations
- Leak tracing in townhouses
- Drain clogs and camera inspections
- Heritage home repiping
A heritage facade does not mean heritage plumbing has to stay.
What to check in a Markham house
In townhouses, find where your water heater and furnace share space and check access around them. In older homes, look for galvanized pipe and crawlspace runs. In 1980s homes, test your shut-off valves under sinks and toilets.

Local note. Before anyone digs near the property line, Ontario One Call locates buried utilities. The city or region owns the sewer and water connection past your property line, so ask them first if the trouble is out at the street.
Common questions
Can I renovate plumbing in a heritage home?
Interior plumbing changes usually do not affect heritage designation, but check with the city if exterior work is involved.
