A home inspection is one of the most valuable tools available to Ontario buyers and homeowners. Here is a complete guide to getting the most out of one.
What a Standard Inspection Covers
Roof condition, flashings, and penetrations. Attic insulation, ventilation, and air bypasses. Exterior cladding, grading, and drainage. Foundation and basement: cracks, moisture, and structure. Electrical: panel, service size, GFCI protection. Plumbing: supply, drain, water heater. HVAC: furnace, AC, ventilation. Interior: drywall, windows, doors, floors.
What Inspections Do NOT Cover
Behind walls and under floors. Environmental hazards (mould, asbestos, radon — require separate specialist testing). Pools and hot tubs (often separate add-on). WETT inspection for wood-burning appliances (separate certification required).
Most Common Ontario Issues Found
Aging roofs (granule loss, curled shingles, missing flashings). Aluminum wiring (1965-1980 era — requires ESA evaluation). Knob-and-tube (pre-1940s). Undersized 100A panels. Basement moisture. Foundation cracks. Missing GFCI in wet areas. Attic air bypasses causing ice dams.

Using the Report
Prioritise life safety items for immediate action. Use specialist follow-ups for uncertain findings. Cosmetic items are normal wear — don’t over-negotiate minor issues.
