How much does general contracting cost in Hamilton?
Most homeowners spend $100-$200 per square foot on a full home renovation - roughly $40,000-$120,000 for a typical project. A light cosmetic refresh can run $15-$60/sq ft; a full gut to the studs reaches $150-$325/sq ft, or $150,000-$220,000+ on a whole 1,500-2,000 sq ft home.
In Hamilton, ON, typical quotes tend to track the Canadian average, so the table below shows these national figures unchanged.
What moves the price: The low end is a cosmetic refresh that keeps the layout, plumbing and wiring in place; the top end is a full gut to the studs with new systems throughout, plus the contractor's management fee on bigger scopes.

|---|---|
| Full home renovation (mid-range) | $100-$150/sq ft $60 to $200 per sq ft |
| Cosmetic / surface refresh | $25-$45/sq ft $15 to $60 per sq ft |
| Full gut renovation (down to studs) | $200-$275/sq ft $150 to $325 per sq ft |

What changes the price of general contracting in Hamilton
- Permits, design, and project management: Structural changes need permits and sometimes an engineer or architect, and the contractor's management fee and design costs layer on top of construction.
- Scope - cosmetic vs. gut: Updating surfaces (paint, flooring, fixtures) costs a fraction of taking a space down to the studs. Removing or moving walls, especially load-bearing ones, is the single biggest swing in price.
- Kitchens and bathrooms: They pack plumbing, electrical, tile, cabinetry, and appliances into a small footprint, so they cost far more per square foot than bedrooms or living rooms.
- Finishes and materials: Laminate vs. custom cabinetry, porcelain vs. natural stone, builder-grade vs. designer fixtures can easily double or triple the cost of the same job.
- Moving plumbing, electrical, and HVAC: Relocating pipes, adding circuits, or upgrading an electrical panel brings in more trades and permits. Keeping fixtures where they are saves thousands.
- Age and condition of the home: Older homes hide surprises - knob-and-tube wiring, asbestos, mould, or out-of-code framing - that must be fixed before the visible work can start.
How general contracting prices vary across Canada
Big cities cost more. Toronto and Vancouver typically run about 20-40% above the national average, driven by higher labour rates, permit costs, and demand. Calgary, Ottawa, and Montreal sit near or modestly above the national average. Smaller cities and rural areas can come in 10-20% lower. The same scope of work can swing 30-50% in total between a small town and downtown Toronto or Vancouver.
