A building and pest inspection is one of the most critical steps before buying a property in Australia.

It’s your best defence against unexpected repair bills, hidden nasties and buyer’s remorse.

But what exactly should you be looking for in these reports?

Let’s break down the essentials so you can move forward with confidence, and maybe even a bit of assurance on auction day.

1. STRUCTURAL INTEGRITY – The bones of the house
The first thing any inspection should cover is the structural soundness of the property.

This includes:

  • Foundations and subfloor
    Look for signs of cracking, subsidence, damp or rot. High moisture levels or visible termite damage in the subfloor can spell big trouble later.
  • Walls and ceilings
    Check for major cracks, sagging or movement. Fresh paint can sometimes hide defects, so don’t be fooled by a quick cosmetic fix.
  • Roof structure
    Inside the roof space, look for sagging beams, cracked or broken tiles, rusty roofing and evidence of leaks or poor insulation.

2. WATER DAMAGE AND DRAINAGE
Water is the enemy of any home. Your inspection should look for:

  • Moisture damage
    Stains or mould on walls and ceilings, musty smells or bubbling paint can all indicate leaks or poor ventilation.
  • Drainage
    Poor drainage around the site, blocked gutters or water pooling near the foundations can lead to long term structural issues.
  • Wet areas
    Bathrooms, laundries and kitchens should be checked for waterproofing, leaks and signs of rot or decay, especially under sinks and around showers.

3. TIMBER PESTS – Termites, borers and friends you don’t want
Australia’s climate is a paradise for timber pests, so pest inspection is non negotiable:

  • Active infestations
    Look for mud tubes, hollow sounding timber or visible termite activity in subfloors, roof voids and around the garden.
  • Past damage
    Even if termites have moved on, old damage can weaken the structure and cost a fortune to fix.
  • Borers and wood rot
    These can also compromise timber elements, especially in older homes or those with poor ventilation.

4. THE EXTERIOR – First impressions and future headaches
A thorough inspection covers:

  • Roof exterior
    Missing or broken tiles, rusted metal, damaged flashing and blocked gutters are all red flags.
  • Walls and foundations
    Cracks, movement or signs of decay in bricks, weatherboards or render need further investigation.
  • Fences, decks, and outbuildings
    Check for structural soundness, rot, termite damage and general wear and tear.

5. THE INTERIOR – More than just a pretty face
Inside the home, inspectors should assess:

  • Doors and windows
    Look for sticking, gaps or rot. These can indicate movement or moisture issues.
  • Floors
    Unevenness, squeaking or soft spots may point to subfloor problems or pest damage.
  • Fixtures and fittings
    Test taps, appliances, lights and smoke alarms for functionality.
  • Insulation and ventilation
    Poor insulation or lack of ventilation can lead to higher energy bills and mould growth.

6. SERVICES AND SAFETY
Don’t overlook the basics:

  • Electrical
    Exposed wiring, outdated switchboards and dodgy DIY jobs are not just annoying, they’re dangerous.
  • Plumbing
    Check water pressure, drainage and look for leaks under sinks and around toilets.
  • Gas and heating
    Ensure all systems are operational and meet safety standards.

7. THE GARDEN AND SITE
The land itself can hide issues:

  • Drainage
    Sloping blocks, retaining walls and garden beds should direct water away from the house.
  • Trees
    Large trees close to the house can damage pipes and foundations.
  • Outbuildings
    Sheds, garages and granny flats need checking for structural soundness and pest activity.

PRO TIPS FOR BUYERS

  • Always use a qualified, independent inspector who is familiar with local building codes and pest risks.
  • Insist on a detailed written report with photos, not just a verbal summary.
  • Attend the inspection if possible. Seeing issues firsthand is invaluable.
  • Don’t be afraid to ask questions. If something isn’t clear, seek clarification before you commit.

A building and pest inspection isn’t just a box to tick, it’s your insurance policy against costly surprises.

If you want to know what’s lurking beneath the surface of your dream home, make sure your inspection covers every nook and cranny.

And if you need help interpreting a report or deciding on a dealbreaker, reach out for an expert second opinion.

After all, you want to buy a home, not a headache!
