Jopie Construction Group is a Hamilton-based general contractor serving Dundas — including Old Dundas, Pleasant View and Lynwood Park. Dundas sits right at the base of the Niagara Escarpment, and many of the town's character homes are older builds where grading and foundation drainage haven't been touched in decades — which is exactly where basement finishing projects run into trouble if waterproofing isn't part of the plan from day one. We assess the foundation, drainage and moisture path before we ever touch drywall, then run the rest of the project — kitchens, bathrooms, additions — the same way: one team, real scheduling, self-performed trades wherever we can.

Why Jopie
Most contractors can swing a hammer; far fewer will actually look at grading and drainage before framing a Dundas basement. We check the foundation and waterproofing first, then bring the same large-scale project-management discipline to the rest of the build, so your job is delivered on time, on budget and without a water problem showing up two years later.
Building and renovating in Dundas: local notes
- Permits go through the City of Hamilton. Dundas is part of Hamilton, so structural work, plumbing changes, egress windows and secondary suites are permitted through the City's building division. We prepare the application and book inspections.
- Escarpment drainage. Homes at the base of the Niagara Escarpment can see more runoff and groundwater. We check grading, downspouts and window wells before finishing a basement.
- Older homes. Older brick and stone houses in Old Dundas often have original foundations and mixed framing, which affects insulation, wall openings and how we plan basements.
- Heritage properties. Some properties in the historic core may be heritage-designated, and exterior changes to those can need heritage review. We confirm this at the walkthrough, before you commit to a design.
FAQ
Do you work in Dundas?
Yes — we regularly take on projects in Dundas, including Old Dundas, Pleasant View and Lynwood Park. We're based in Hamilton, right next door to Dundas, and treat Dundas as one of our core service areas, not an afterthought.
Why does basement waterproofing come up so often in Dundas?
Dundas sits at the base of the Niagara Escarpment, and a lot of the town's character homes are older builds where grading, weeping tile and foundation waterproofing were never updated. We assess the foundation and drainage as part of any Dundas basement renovation, not as an add-on after a problem shows up.
Do you handle both residential and commercial projects?
Yes. We manage and build residential renovations and additions as well as commercial and industrial projects across Hamilton and the surrounding area.
What makes Jopie different from other contractors?
Our own crew self-performs much of the work, and one team plans, schedules and manages your project from start to finish — instead of you coordinating separate trades yourself.
Are you insured and WSIB-covered?
Fully insured and WSIB-covered. Documentation provided before work begins.
