With years of experience conducting building inspections in Australia, we’ve identified the most frequent problems found in residential properties. Here’s what you need to watch out for:
1. Termite Damage
Termites are one of the most destructive pests in Australia. They can silently destroy timber structures from the inside out, often without any visible signs until the damage is severe. Warm and humid areas like Queensland and northern NSW are especially prone to termite activity.
What to look for:
- Timber that sounds hollow or feels soft
- Mud tubes on walls (a clear sign of termite activity)
- Warped doors or sagging floors
👉 Pro tip: Always request a pre-purchase pest and building inspection. It’s a small cost compared to the price of termite repairs.
2. Foundation Movement
Thanks to Australia’s highly reactive clay soils, foundation movement is a common issue. As moisture levels change, the soil expands and contracts—causing floors to slope, walls to crack, and doors to stick.
Warning signs include:
- Diagonal cracks around windows or doors
- Uneven floors that feel bouncy
- Gaps between walls and skirting boards or ceiling
If you notice any of these, book a structural assessment with a qualified engineer.
3. Roof Leaks and Drainage Problems
Blocked gutters, poor drainage, or neglected roof maintenance can allow water to leak into the home. Over time, this leads to wood rot, mold, and even structural failure.
What to check for:
- Water stains on ceilings or walls
- Musty smells or visible mold
- Blistering or peeling paint
4. Unapproved Renovations or Poor DIY Repairs
Previous owners may have covered up major problems with cosmetic fixes or taken on DIY jobs without proper building permits. These shortcuts can pose serious risks to safety and compliance.
Watch out for:
- Inconsistent flooring or mismatched finishes
- Added structures like pergolas or decks without visible support
- Fresh paint in limited areas (could be hiding cracks or stains)
Before buying, get an engineer’s opinion on structural integrity and compliance.
