A professional Calgary home inspection ($400-$650 typical for detached homes) is essential pre-purchase due diligence. Inspectors examine roughly 1,500 components and report findings — both major issues and minor maintenance items. Understanding what the inspection covers (and what it doesn't) helps Calgary buyers make informed decisions.

What Calgary home inspectors examine

Exterior

  • Roof condition, age, remaining life, flashing, eavestroughs, downspouts, fascia, soffits
  • Siding (vinyl, brick, stucco, wood) condition and integrity
  • Windows: seals, frames, condensation between panes (sign of failed gas-filled units)
  • Doors and door frames
  • Foundation visible exterior portions, cracks (vertical typically OK, horizontal/stair-step concerning)
  • Grading and drainage (water flow away from foundation)
  • Walkways, driveways, patios, decks, fences
  • Yard structures (sheds, garages — included if part of property)

Interior structural and mechanical

  • Foundation interior, basement walls, floor slab cracks
  • Framing visible in unfinished areas
  • Furnace age, condition, recent service history (typical Calgary furnace life: 15-20 years)
  • Hot water tank age (typical life 10-15 years), water shutoffs
  • Air conditioning if present (typical Calgary AC life 12-18 years)
  • Electrical panel and visible wiring (concern with aluminum wiring 1970s, knob-and-tube earlier)
  • Plumbing visible portions (concern with polybutylene 1980s-1990s, Kitec 2000s)
  • Insulation visibility (especially attic), ventilation

Interior cosmetic and functional

  • Walls, ceilings, floors visible condition
  • Doors, windows, moldings, trim
  • Bathrooms: fixtures, drainage, ventilation, water pressure
  • Kitchen: appliances (range, fridge, dishwasher if included), plumbing, ventilation
  • Stairs, railings, hand-rails
  • Garage: doors, automatic openers, walls, floor

Calgary-specific issues to watch for

Foundation cracks

Calgary's clay-rich soil and freeze-thaw cycles cause typical hairline foundation cracks (vertical orientation) — generally not concerning. Horizontal or stair-step cracks indicate structural pressure and require structural engineer consultation. Major foundation repair: $20,000-$80,000+.

Sewer line condition (older homes)

Calgary homes built before 1985 often have clay sewer lines that crack, root-infiltrate, or collapse. Modern sewer line replacements use PVC. Sewer scope inspection (specialty $250-$400) checks line condition and is recommended for any pre-1985 home. Sewer line replacement: $7,000-$25,000+.

Asbestos (pre-1990 homes)

Calgary homes built before 1990 may contain asbestos in popcorn ceilings, floor tiles, insulation around pipes, vermiculite attic insulation, and certain drywall textures. Asbestos is generally safe if undisturbed, but renovations or removal require certified abatement ($3,000-$30,000+ depending on extent).

Aluminum wiring (1970s)

Calgary homes built 1965-1975 often have aluminum branch wiring that's prone to overheating and connection failures. Solutions: COPALUM crimping (proper professional connection method, $5,000-$15,000) or replacing all aluminum branches (~$15,000-$35,000). Insurance premium often higher with aluminum wiring.

Polybutylene plumbing (1980s-1990s)

Calgary homes built 1978-1995 often have grey polybutylene plumbing — known to fail catastrophically. Insurance often refuses to cover homes with polybutylene. Replacement (PEX or copper): $8,000-$25,000+ depending on home size.

Kitec plumbing (2000s)

Calgary homes built 1995-2007 may have Kitec plumbing — orange/blue PEX-aluminum-PEX product subject to a class-action settlement due to early failures. Insurance often refuses or limits coverage. Replacement: $5,000-$15,000.

Vermiculite insulation

Some Calgary homes have vermiculite (Zonolite) attic insulation — a brand contaminated with asbestos. If vermiculite is present, the home will require professional removal during any attic work or renovation. Inspect attic carefully.

Inspection report red flags vs minor items

Most Calgary inspection reports identify 30-80+ items across the report. The vast majority are minor or routine maintenance. Red flags that warrant follow-up specialty inspections or negotiation:

  1. Foundation issues (horizontal cracks, water intrusion, uneven floors)
  2. Roof at end-of-life (need replacement within 2 years)
  3. Furnace at end-of-life (need replacement within 2 years)
  4. Polybutylene or Kitec plumbing
  5. Aluminum wiring
  6. Asbestos confirmed in friable materials
  7. Mold (especially behind walls)
  8. Sewer line failure indicators
  9. Active water leaks or water damage
  10. Insurance-affecting issues (knob-and-tube wiring, certain roof conditions)

How to use Calgary inspection results

After inspection, Calgary buyers typically have three options:

  1. Accept and proceed — minor issues only, no concerning findings. Most Calgary inspections fall here.
  2. Negotiate price reduction or repairs — request seller credit ($X off purchase price) or specific repairs before closing. Common for moderate issues.
  3. Walk away — major foundation, sewer, plumbing, electrical, or environmental issues that exceed your renovation tolerance. The conditional offer protects this option.

Specialty inspections worth considering

  • Sewer scope ($250-$400): pre-1985 homes especially
  • Asbestos test ($150-$500): pre-1990 homes with renovation plans
  • Mold inspection ($300-$700): visible water damage or musty smell
  • Foundation engineer ($600-$1,500): horizontal cracks or settlement concerns
  • Pest inspection ($150-$300): suspected rodent or insect issues
