GTA Home Inspection and Pre-Purchase Renovation Budget Guide 2026
Buying a GTA home that needs work? A thorough pre-purchase inspection and realistic renovation budget is the difference between a great investment and a money pit.
Critical Systems to Inspect
Roof: Age, shingle condition, flashing, attic staining (ice dam evidence). Replacement: $10,000-30,000+.
Electrical panel: Federal Pacific, Zinsco, or aluminum wiring = insurance red flag. Knob-and-tube wiring limits insulation. Panel upgrade: $3,000-6,000. Full rewire: $15,000-35,000.
Foundation: Cracks, water staining, efflorescence, bowing walls. Crack injection: $400-1,200 per crack. Interior waterproofing: $8,000-18,000.
HVAC: Age and condition of furnace, A/C, heat pump. Furnace replacement: $3,500-7,000. A/C: $4,000-8,000.
Plumbing: Lead or galvanized pipes, cast iron drain condition, water pressure. Full replumb: $15,000-40,000.
Attic insulation: Top-up to R-60: $2,000-5,000.
Building a Pre-Purchase Budget
- Get 2 contractor quotes on each inspection finding before finalizing purchase
- Separate: immediate (safety/code) vs. phased (cosmetic) vs. wish-list
- Use mandatory costs as negotiating leverage
