Thinking about buying a home on the Gold Coast? Here are the defects inspectors find most often — and why they matter before you sign on the dotted line.

Buying a home is one of the biggest decisions you'll ever make. It's exciting, nerve-wracking, and let's be honest, a little overwhelming.

That's exactly why a building and pest inspection exists. It's your chance to find out what's really going on with a property before you commit. And after inspecting hundreds of homes across the Gold Coast, we can tell you — very few properties come back with a perfectly clean bill of health.

That's not necessarily a bad thing. Most defects are manageable when you know about them upfront. The real risk is not knowing.

So, what do building and pest inspectors actually find? Let's walk through the most common defects we come across, what they mean, and what you should do about them.

1. Cracking in Walls and Brickwork

This is one of the most common things we see, and it's also one of the most misunderstood. Not all cracks are created equal.

Hairline cracks in plaster are usually cosmetic and nothing to lose sleep over — they're often caused by normal settling or minor thermal movement. But when cracks start appearing in external brickwork, especially diagonal cracks near windows or doorways, it can be a sign of something more serious like differential foundation movement.

We classify significant cracking as a Major Defect, and in those cases, we'll recommend getting a qualified structural engineer involved to work out what's going on underneath.

What to look for: Cracks wider than 2mm, stair-step patterns in brickwork, cracks that appear on both the inside and outside of a wall.

2. Damaged or Deteriorating Roof Tiles

Your roof is the first line of defence against the elements, so when tiles are cracked, chipped, or slipping out of place, it's something that needs attention.

We regularly find damaged concrete and terracotta roof tiles, particularly on older homes. Sometimes it's storm damage, sometimes it's just age catching up. Either way, damaged tiles can let moisture into the roof cavity, and once water gets in, it can start affecting the timber structure, sarking, and ceiling linings below.

What to look for: Chipped or broken tiles visible from the ground, staining on ceilings inside the home (a sign of existing leaks), and moss or lichen growth which can accelerate tile deterioration.

3. Blocked or Overflowing Gutters

It sounds minor, but clogged gutters cause more downstream problems than most buyers realise. When gutters are full of leaf litter and debris, rainwater overflows and runs down the walls, into the eaves, and pools around the base of the house.

Over time, this can lead to moisture damage to fascia boards and external cladding, and — here's the big one — create the damp conditions around the building's perimeter that termites absolutely love.

On the Gold Coast, where we get solid summer storms, keeping gutters clean isn't just maintenance — it's termite prevention.

What to look for: Visible debris in gutters, water staining down external walls, pooling water near the foundations after rain.

4. Poor Drainage and Water Pooling

Speaking of water, drainage issues are something we flag regularly. If the ground around a property slopes toward the house instead of away from it, or if there's no effective stormwater system in place, water can accumulate against foundations and subfloor areas.

This is a problem for two reasons. First, prolonged moisture exposure can affect the structural integrity of footings and slabs. Second, it creates conditions that are highly conducive to termite activity. Subterranean termites are drawn to moisture, and a constantly damp subfloor or foundation is essentially a welcome mat.

What to look for: Low-lying areas around the perimeter, evidence of water staining on lower walls, damp or musty smells in subfloor areas.

5. Leaking Plumbing and Hot Water Systems

Plumbing leaks are another frequent finding — and they're not always obvious. We often discover leaks at the base of hot water systems, under sinks, or around laundry connections. Sometimes the homeowner knows about them. Sometimes they don't.

A leaking hot water system isn't just a plumbing issue. If it's located near the building, the sustained moisture can attract subterranean termites to the area. We classify these as both a defect and a condition conducive to timber pest attack.

What to look for: Damp patches around the hot water unit, water stains under sinks or around taps, unusually high water bills (which can indicate a concealed leak).

6. Subfloor Moisture and Ventilation Issues

For homes with a subfloor (raised houses, Queenslanders, and older builds), the condition underneath is just as important as what you see above.

We commonly find subfloors with elevated moisture levels, inadequate ventilation, and in some cases, stored items or debris that restrict airflow. All of these create an environment where timber pest activity can thrive.

Proper subfloor ventilation is critical for keeping moisture levels in check and protecting the structural timbers that hold the house up. When ventilation is poor, timbers stay damp, and damp timbers are vulnerable to both termite attack and fungal decay.

What to look for: Vents that are blocked or covered, visible dampness on subfloor timbers, musty odours coming from beneath the house.

7. Garden Beds and Soil Against Walls

This is one of the most common — and most easily avoidable — risk factors for termite attack. When garden beds are built up against the external walls of a house, they can bridge physical termite barriers and provide concealed access for subterranean termites.

We see this on a huge number of properties. It looks nice from a landscaping perspective, but from a pest management perspective, soil in direct contact with wall cladding is a real concern.

The fix is relatively simple: maintain a clearance between soil levels and the bottom of the wall cladding so that any termite barrier remains visible and intact.

What to look for: Soil, mulch, or garden beds touching the external walls, rendered walls where you can't see where the slab edge meets the wall, garden edging that traps moisture against the building.

8. Evidence of Termite Activity (Past or Present)

This is the one that makes every buyer's heart skip a beat, but it's more common than you'd think. On the Gold Coast, we operate in one of the highest-risk termite zones in Australia. Finding evidence of termite activity — whether past or present — is not unusual.

Past activity might include old mudding (shelter tubes) on subfloor piers or framing, or timber that shows signs of previous damage that has since been treated. Present activity means live termites are in the building, and that requires immediate action.

Either way, knowing about it before you buy is the whole point. It gives you the opportunity to negotiate, request treatment, or get specialist advice on the extent of any damage.

What to look for: Mud tubes on piers, stumps, or walls; hollow-sounding timber; doors or windows that suddenly stick; small holes in timber framing.

9. Electrical and Safety Hazards

While a building inspection isn't an electrical compliance audit, we do note visible electrical safety concerns. Common findings include exposed wiring, missing switchboard covers, outdated wiring systems (like old rubber-sheathed cabling), and the absence of safety switches.

These are important to be aware of because they can pose a genuine safety risk, and bringing older electrical systems up to current standards can be a significant cost.

What to look for: Old-style fuse boxes instead of modern circuit breakers, exposed or loose wiring in the roof space or subfloor, lack of safety switches on the switchboard.

10. Moisture in Wet Areas (Bathrooms, Laundries, Ensuites)

Bathrooms and laundries are high-moisture areas by nature, and they're a common source of defects — especially in older homes or renovations that weren't done to the best standard.

We often find signs of failed waterproofing, including swollen or soft flooring near showers, mould growth on walls or ceilings, and water staining on the other side of bathroom walls. Poor waterproofing can lead to structural damage over time and create conditions conducive to mould and timber pest activity.

What to look for: Soft or spongy flooring near the shower, mould or mildew on grout, walls, or ceilings, water stains on walls adjacent to bathrooms.

So, What Should You Do?

If you're in the process of buying a home, the best thing you can do is get a professional building and pest inspection before you go unconditional. It's a relatively small investment compared to the cost of the property — and the potential cost of fixing issues you didn't know about.

A good inspection report won't just list defects. It will explain what they mean, how serious they are, and what action you should take. That information puts you in a strong negotiating position and helps you make an informed decision about one of the biggest purchases of your life.

At CYTE Building Inspections, we inspect properties across the Gold Coast and surrounding areas. We provide clear, detailed reports that are written in plain English — no jargon, no fluff — so you know exactly what you're dealing with.
