Local knowledge

The Valley Town's old foundations.

Dundas was an industrial town before Hamilton was: by 1845 it had 20 manufacturing businesses to Hamilton's nine, helped by the Desjardins Canal to the bay. Homes from that era are still here. In the Cross-Melville district, houses date from the 1820s to the 1940s, including an 1860s home on Melville Street built on a limestone foundation. The Melville-Park West area was built mostly between 1880 and 1930 as red-brick worker housing.

Dundas has barely grown in the last two decades, with 24,385 people in 2001 and 24,150 in 2021. With so little new building, the older homes downtown and on the heritage streets keep needing work, and they're where we do the most underpinning, stone wall repair and partial rebuilds. Many basements were built as cellars and are too low or too damp to finish without real foundation work.

The town sits at the foot of the Niagara Escarpment, with Spencer, Sydenham and Ancaster creeks running through the valley. Wet ground against old stone walls speeds up mortar loss and movement, so we look at drainage alongside the structure on every job.

Questions

Dundas questions, answered

My house is in a Dundas heritage district. What does that mean for foundation work?
Dundas has two Heritage Conservation Districts: Cross-Melville, designated in 1990, and Melville-Park West, which took effect in June 2026. In Melville-Park West, exterior alterations beyond the minor ones the plan lists need a heritage permit, and on contributing properties additions have to go at the side or rear. We check what applies to your address before planning any outside excavation.
Do I need a permit for underpinning in Dundas?
Yes. Dundas is part of the City of Hamilton, and permits come from the City's Building Division. Work near the creeks or the escarpment can also need approval from the Hamilton Conservation Authority or the Niagara Escarpment Commission, which the City's permit checklist asks about. We sort out what applies before we start.
Can a stone foundation be waterproofed as well as repaired?
Yes, and it usually should be. Once a stone wall is exposed for repointing or underpinning, it's the right time to add drainage and waterproofing, and our sister company Basement Worx does exactly that. We can quote both together.
