Getting the trade sequence wrong in a renovation is one of the most expensive mistakes Ontario homeowners make. Here is the correct order for 2026.
Why Sequence Matters
Installing flooring before painting means paint drips on new floors. Finishing drywall before HVAC rough-in means cutting it open again. Countertops before cabinets are secured is impossible. Each mistake adds cost, time, and stress.
The Correct Sequence
- Demolition and structural changes. Address foundation/moisture issues.
- Rough-in: plumbing (drain, supply, vent), electrical (panels, circuits, neutral wires), HVAC (ducting, equipment curbs), low-voltage (Cat6, speaker, EV conduit).
- Rough-in inspections before closing walls — mandatory for permitted work.
- Insulation and air sealing (spray foam at penetrations, batts in cavities).
- Drywall (hang, tape, mud, sand, prime).
- First coat painting before trim, cabinets, and flooring.
- Hard finishes: tile, hardwood/LVP flooring, cabinet installation, countertop template and install.
- Trim and interior doors.
- Final coat painting and touch-up.
- Final fixtures: plumbing trim, electrical devices, HVAC grilles, appliances.
Key Rules
Paint before hard trim and flooring. Cabinets before countertops. Countertops before plumbing trim. Follow this and eliminate the most expensive rework scenarios.
