How much does general contracting cost in Markham?
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 Markham, ON, typical quotes tend to come in above the Canadian average, so the table below nudges these national figures up by roughly 15% at the low end of each range and up to 30% at the top end.
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) | $120-$180/sq ft $70 to $250 per sq ft |

What changes the price of general contracting in Markham
- 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.
- 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.
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.
These are typical Markham-area price ranges based on 2026 Canadian market data, not quotes. Your actual cost depends on the size and details of your project. Post your project on Bidmii to get free quotes from the 29 general contracting contractors listed in Markham above.

What is the difference in cost between a cosmetic and a gut renovation?
A cosmetic renovation keeps the layout, plumbing, and wiring in place and just updates surfaces - paint, flooring, fixtures, maybe cabinets - so it is the cheapest route, often $15-$60 per square foot. A gut renovation strips the space back to the framing and rebuilds everything, including new plumbing, electrical, insulation, and drywall. Because you are paying for every trade, gut renos usually cost 3 to 5 times more per square foot than a cosmetic refresh.
How can I keep my renovation budget under control?
The biggest savings come from keeping your layout the same - leaving kitchens, bathrooms, and load-bearing walls where they are avoids the most expensive work. Choose mid-range finishes where they will not be seen up close, get a detailed written quote that breaks out labour, materials, and the contractor's fee, and set aside a contingency of 10-20% for the surprises older homes almost always hide.
How much does a kitchen renovation cost in Canada?
Most Canadian kitchen renovations run $25,000 to $75,000 in 2026. A cosmetic refresh can come in around $10,000-$25,000, while a full custom kitchen with new cabinets, stone counters and layout changes can reach $60,000-$100,000 or more.
