When buying property in Adelaide, common building defects are often influenced by location. Soil conditions, site slope, vegetation, and proximity to the coast all play a role in how a home performs over time.

Below are some of the most common building issues found across different Adelaide suburbs—and more importantly, why they occur.

Coastal Adelaide (Semaphore, Glenelg, Brighton)

In coastal areas such as Semaphore, homes are exposed to salt-laden air—but moisture issues are often made worse by construction factors in older properties.

Common building defects include:

• Salt damp affecting internal and external walls
• Corrosion to steel lintels, roofing, and fixings
• Elevated subfloor moisture due to:
  • Lack of effective damp proof courses
  • Poor subfloor ventilation
  • Limited clearance beneath timber floors

In many older homes, inadequate damp proofing combined with restricted airflow creates persistently damp conditions. Over time, this can lead to rising damp, timber decay, termite infestations.

Eastern Suburbs Adelaide (Burnside, Magill, Norwood)

Suburbs east of the CBD such as Burnside and Unley are commonly affected by reactive clay soils.

Common building defects include:

• Cracking to walls and ceilings
• Uneven or sloping floors
• Doors and windows becoming misaligned

These issues are typically caused by seasonal soil movement. Reactive clays expand when wet and shrink during dry periods, placing stress on footings and slabs. Homes with shallow footings, poor site drainage, or large trees nearby are more susceptible to ongoing movement.

Southern Adelaide (Flagstaff Hill, Aberfoyle Park)

In areas such as Flagstaff Hill, termite risk is higher due to surrounding vegetation and environmental conditions.

Common building defects include:

• Termite damage to structural timbers
• Evidence of previous infestations
• Inadequate or outdated termite management systems

Termites are attracted to moisture and concealed entry points. Contributing factors often include poor drainage, subfloor dampness, garden beds against external walls, and lack of regular inspections. Damage is frequently hidden and may only be detected through a thorough inspection.

Sloping Blocks & Retained Land (Trott Park, Hallett Cove)

Suburbs like Trott Park and Hallett Cove commonly feature sloping sites and retained land.

Common building defects include:

• Leaning or failing retaining walls
• Poor drainage causing water build-up behind walls
• Movement impacting footings and structures

These issues are usually linked to inadequate construction or drainage design. Retaining walls require proper footing depth, drainage systems (such as agricultural drains), and allowance for soil loading. When these are missing or fail over time, pressure builds up and leads to movement or collapse.

Why Location Matters in a Building Inspection

Not every property in these areas will have these issues—but the likelihood is higher depending on location, construction type, and maintenance.

Understanding these patterns allows buyers to:

• Ask better questions
• Identify risks earlier
• Avoid unexpected repair costs

A professional building inspection in Adelaide should assess not only visible defects, but also the underlying causes based on the property’s location and conditions.

Final Thought

Every home is different, but patterns emerge across suburbs. Knowing what’s common in a particular area can make a significant difference when purchasing property.

Why You Still Need a Building Inspection for a Brand New Home in Adelaide 🚧🏠

Introduction: Buying a newly built home may seem worry-free, but issues can still arise. Construction mistakes, material flaws, and oversights are common. This post explains why a building inspection for new homes should be a top priority for any buyer.

Building Standards Don’t Always Guarantee Quality 📝

Australia has solid building codes and standards, but let’s face it — enforcement can vary, and not every builder follows them to the letter. Some builders focus on cost-cutting, and that can lead to things like:

• Rushed finishes or structural flaws.
• Cutting corners with materials or design to save time and money.

Getting an inspection means you’ll know if there are any of these “hidden surprises” that could end up costing you more down the road.

The Materials Matter 🧱

In Adelaide, many builders use lightweight materials for homes, rather than the brick-and-mortar construction we grew up with. This choice of materials can lead to issues over time, like:

• Warping, cracking or water leaks.
• Greater vulnerability to pests such as termites.

An inspection will let you know if your home’s materials are up to par and whether there are any specific things you should keep an eye on as the house settles.

The Rush to Build Can Lead to Rushed Work ⏱

Australia’s housing market is booming, and builders are under pressure to keep up. With the government encouraging more housing development, this often means:

• Builders and Developers are more focused on getting projects done quickly rather than making sure each house is built well.
• Quality can slip through the cracks, especially in high-demand areas.

A building inspection for new homes can reveal whether any of this “quantity over quality” mindset affected your new home, helping you get issues addressed before collecting the keys

Rising Building Costs and Budget Cuts 📈

Building materials in Australia are still pricier than they were before the pandemic, and some builders may cut corners to manage costs. This can mean:

• Choosing lower-quality materials.
• Using unlicensed or inexperienced contractors.
• Rushing through stages of construction, especially in areas that aren’t obvious at first glance.
• Too many houses for the Building Supervisor to really keep an eye on.

An inspection gives you a chance to double-check that cost-cutting didn’t result in compromises to your home’s quality, saving you potential repair costs and stress later.

Know What You’re Really Getting 🔍

New homes come with big expectations, but even brand-new construction isn’t always perfect. There can be a gap between what’s promised and what’s delivered, so an inspection gives you:

• A clear picture of any small fixes or repairs that the builder must rectify.
• Leverage to negotiate with the builder for any necessary adjustments or maintenance before you move in.

Knowing the real state of your home helps you feel confident that you’re getting what you paid for and sets you up for long-term peace of mind.

Conclusion: Just because a home is brand new doesn’t mean it’s flawless. In a fast-paced market with rising material costs, even new builds can have issues that only a professional inspection can identify. A building inspection ensures your home’s quality and safety, boosts your confidence, and provides peace of mind for years.

“Don’t skip a building inspection for new homes in Adelaide.” Book now to ensure your new home is up to standard and avoid future surprises.

Firstly, we’re seeing a reduction in new listings, a shortage of rental properties, and high levels of interstate interest. As a result, homes are receiving multiple offers after just one open inspection. Additionally, many agents are using misleading price guides to stir up more interest, which only adds to the confusion for buyers.

This creates a lot of pressure on you. You’ve likely missed out on several properties and are exhausted from spending hours online searching for your new home, only to face long lines at open inspections.

Moreover, with so much happening during these rushed and busy inspections, it’s easy to overlook important details. That’s where Trust Inspex comes in — ensuring that you don’t miss anything at open inspections today.

Importance of Connecting Downpipes

Connecting downpipes is crucial, especially in South Australia, where many homes are built on highly reactive clay soils (H1 & H2). These soils swell when wet and shrink when dry, making Adelaide’s soil some of the most reactive in the country. Controlling moisture around your home is essential to prevent soil movement. Keeping moisture levels consistent throughout the year means watering around your home during droughts and ensuring stormwater drains into the street or sumps.

Soil Movement and Moisture Control

The table below shows typical soil movement at a site, which can be minimized by controlling moisture and connecting downpipes.

Downpipes: A Standard Practice

For the past 40 years, connecting downpipes has been standard practice. However, many older homes still have downpipes discharging water near the footings. In most cases, houses without connected downpipes also show diagonal cracks, as seen in the video.

How to Connect Downpipes

Connecting downpipes to stormwater drains is a simple process. You may need to remove sections of paving to run pipes to the street. The cost is typically around $3,000. This is another reason to schedule a pre-purchase building inspection before buying.

Dealing with Leakage in Old Pipelines

Leakage is common in old earthenware pipelines, which are vulnerable to soil movement and tree roots. If you suspect leakage is causing cracking or rising damp, upgrading to a new PVC system might be necessary.

Testing for Leaks Before Replacement

Before replacing old drains, ask a plumber to block the pipe and perform a static water test to check for leaks—it may still be in good condition.

Anyone who owns an older house in South Australia should definitely take the time to read this guide written by the Department for Environment and Heritage. It’s an invaluable resource for understanding Home Maintenance practices, especially for older properties.

The guide contains informative text and illustrations addressing common issues such as salt damp, cracking, ventilation, and more. To manage these challenges effectively and preserve the structural integrity of your home, proper Home Maintenance is essential.

“For example, one of the two most common sources of dampness in old buildings is rising damp – moisture that rises from the ground into the base of masonry walls. When this moisture contains high levels of dissolved salts, salt attack intensifies the problems of rising damp. South Australians commonly refer to the combined effect as salt damp.

This issue is perhaps the single most destructive force working against old buildings in the region.”

To stay ahead of such issues, regular inspections should play a key role in your Home Maintenance routine. By inspecting areas prone to dampness, cracks, or ventilation blockages at least once per season, you can identify problems early and avoid costly repairs.

For instance, you should check:

• Masonry walls and foundations for signs of rising damp or salt deposits.
• Roofs, gutters, and downpipes for damage or blockages that may lead to water ingress.
• Windows, doors, and subfloor spaces for proper ventilation and signs of rot.
• Visible signs of moisture in bathrooms.

Additionally, the guide includes a seasonal Home Maintenance routine that simplifies the process. With regular inspections and proactive care, you can ensure your property remains in excellent condition year-round and continues to stand the test of time.

TOO MUCH WATER?

Inadequate drainage in part of the garden is a problem that affects many gardeners. The problem can be a constant one where it occurs all year round or it may be seasonal. It might be that the stormwater drains into one corner of the yard resulting in at best moist soil and at worst a complete bog. It may be just a low spot that collects all the water from the surrounding area. Whatever the reason, there are ways of turning a boggy or wet area to your advantage. Some plants thrive in wet areas, and with the right plants, you can still achieve an interesting and attractive garden in a wet area.

What can cause wet areas in your garden?

• Leaking pipes.
• Wastewater from your house that is drained into your garden.
• Rising water table (e.g. particularly from over-irrigation in rural areas) or naturally occurring springs
• Water from surrounding properties may drain into your garden. This could be naturally occurring or may result from your neighbours diverting water, either intentionally or unintentionally, from their property into yours.
• Low areas or depressions provide a site for water to collect. The water could be from rainwater, garden irrigation, etc.

Problems with wet areas or inadequate drainage

• High levels of moisture around the house increase the possibility of structural movement and or subsidence in the footings. Adelaide has very reactive clay soils, which expand during the wet seasons and contract during the dry. It is important to try and stabilise this ground moisture content.
• High moisture also increases the risk of a possible termite infestation.
• The presence of stagnant water can be a health hazard. It can also be very smelly.
• Access is restricted (e.g. you can sink into muddy areas)
• Visually the area may look quite ugly. It may also be quite messy for kids and animals (fence off or plant so densely that access is restricted).

OVERCOMING PROBLEMS WITH BOGGY OR WET AREAS

Wet areas can be overcome in the following ways:

• Prevent or reduce the amount of water reaching the garden. For example, blocked drains can be repaired, leaking pipes can be fixed, stormwater diverted elsewhere, etc.
• Fence off, or plant trees and shrubs to screen the area off. This can prevent access to the wet area as well as blocking it off visually. It doesn’t however, fix the problem.
• Improving drainage

For heavy clay soils:

• Dig in lots of organic material (e.g. mulch or wood shavings). As this decomposes it improves soil structure and nutrition, helping drainage as well as increasing the soil’s capacity to absorb water.
• Add gypsum or Multicrop’s clay breaker. These products open up hard soils allowing better drainage.
• Install drainage pipes to take the water away.

For low spots:

• Dig organic matter into the soil to help absorb excess water and improve soil structure.
• Create a sump pit at the lowest point (see the section on creating a sump)

Raise Levels or Fill Depressions

Get an earthmoving machine in (or do it by hand if it’s not a big job) and change the levels of your property so water drains away instead of collecting in any one part. Build a raised garden bed on the surface of the ground.

• Plant with water-loving plants, 
  • If the area is always wet
    • Use plants that like continuously wet soil, and do not mind being waterlogged at times (e.g. Iris, Papyrus etc.). Spread a 4 – 5 cm layer of coarse sand or pebbles over the surface to restrict the growth of algae or any other putrid smells
  • If the area sometimes dries out:
    • Create a bog garden by digging out the area, lay a double thickness of black plastic, fill with a good quality, highly organic compost then plant with bog plants.
    • Use plants that tolerate or even like being waterlogged but will tolerate some drier periods.
• Build a pond and drain surface water into the pond.

IF YOU HAVE NOWHERE TO DRAIN TO

Often the home gardener will find that they have nowhere to drain excess water to. One way of inadequate drainage is to dig a sump. Try to avoid placing it near other pipes, drains, etc. The technique for creating a sump is as follows:

1. Excavate a hole approximately 1 m wide x 1.5 m deep. The soil removed can be used elsewhere or discarded.
2. Fill the hole to within 300 mm of the surface with coarse material such as rubble, rocks, etc.
3. Lay your drains so that they terminate (discharge) level with the top edge of the rocks.
4. Add a layer of 150 mm of sand, then fill the remaining part of the hole up to ground level with a good quality sandy loam or loam soil.
5. Plant lawn or other plants over the excavated area.

It’s OK to fall in love with a house, but this should be after you’ve had it inspected.

Attending open inspections, one after the other can start to become a drag or you may have found what seems like your perfect home in just a few weeks, it is very important to keep your eyes wide open throughout this entire process.

The following is a quick guide for you to follow when attending open houses.

The first thing to look at when you arrive at the house is the slope of the block, does it look like water is draining towards the house? Drainage issues can cause movement and cracking of the foundations, it can also encourage termites.

Landscaping is important, is there paving around the perimeter of the home? Are there large trees near the house? Think of the damage a tree root can do to the pavement or footpath, they can do similar damage to the foundation of the home.
Leaves from trees can block gutters and downpipes causing them to rust and stormwater to overflow back inside.
Where does the stormwater go? Downpipes connected to stormwater drains or is the water being discharged next to the house?

Cracking of buildings is a major problem in Adelaide for two reasons: first, large areas occupy expansive soils (mostly black and red-brown clays); second, many dwellings are solid masonry because of a local timber scarcity, and solid brick houses are more prone to cracking than timber-frame brick veneer structures.

Nearly all older homes in Adelaide and even some newer homes will have cracks, the majority of these will be slight and not of concern, however, some houses will have significant structural cracking which could be very costly.
