Everybody deserves to feel safe in their home. It can be stressful when signs of structural damage are discovered. There are many issues that need to be addressed, such as uneven floors, warped ceilings, gaps between walls, pest infestations, etc. It is important to arrange independent building inspections with a professional in Brisbane & the Sunshine Coast, such as CCBI, in these cases so that the extent of damage can be determined.

This guide will help you identify structural problems in your house and prevent them from getting worse.


Termites, despite their small size, can cause significant structural damage to homes over time. They can eat away support beams, ceiling joists, and wall studs. It is easy to mistake termite-induced structural damages, such as wall cracking and sagging ceilings, for normal movement. If termites aren’t treated soon, a house can become unsafe and unlivable.

Sagging Roofs & Roof Leaks

Roof cladding can last up to 30+ years before needing to be replaced. Your roof may be leaking even though it has not reached its end of life. This could be caused by timber frame movement, weather-induced damage or poor maintenance. It is crucial to repair roof leaks quickly as water can cause serious damage to internal structures and costly damage. Uneven or sagging roof lines can indicate problems with the roof structure. This could be due to termite damage, removal of load-bearing walls, or improper sizing of framing timbers.

Cracks in Walls and Ceilings

While not all cracks in walls and ceilings indicate structural damage, it is important to be vigilant to identify any potential problems. Cracks in the ceiling above doors with a step pattern, cracks that have uneven floors or a sagging ceiling are indicators of serious problems that need to be addressed immediately.

Uneven Floors

Uneven floors can be severe and require immediate attention. Poor construction and settling foundations are the most serious causes. A structural contractor must be consulted to diagnose the problem. Cracked floor joists, termite infestation, and insufficient sub-floor support are all possible causes of uneven floors. Older homes may benefit from restumping.

Damp Sub-Floors

Lack of ventilation in subfloors can prevent evaporation and cause humidity and mould growth. An increase in dampness can cause the rotting of floor timbers. This can be easily identified by surface stains or other signs. There are many solutions, from clearing blockages that hinder evaporation to increasing ventilation and drainage.

Timber Rot

Timber is strong and durable. However, it must be protected from the elements so that it doesn’t begin to decay. Timber should not be exposed to conditions that allow harmful fungi to thrive and grow. This means that your timber should not be exposed to excessive moisture or nutrients that promote the fungus, commonly called rot.

Concrete crumbling

Exposition to chemicals and high moisture is the main cause of crumbling brickwork and concrete. Concrete absorbs salts and chlorides, which leads to a chemical reaction in the concrete. The chemical reaction causes crystals to grow and expand, causing the concrete to separate. The steel reinforcement reacts with salts to cause corrosion. This can lead to steel expanding up five times its original size and separating the material from the bond. It is common to see mortar erosion in brickwork beneath the waterproofing membrane or damp coarse. This is a sign that there are other problems that may need to be addressed.

Warped Ceilings

There are visible cracks in the ceiling, such as wavy, cracked cornices or warped ceilings. These cracks should be fixed as soon as possible. After the cracks have been fixed, repairs can be made to the plaster.

Exposed Gaps between Walls

Sagging floor joists can cause exposed gaps between external and internal walls. This is often caused by termites or support pillars that are too far apart. Foundation settling can also cause them. This is when the ground shifts or changes, affecting your home.

Windows and Doors that are not compatible with your needs

If doors are unable to close properly or windows become stuck in their frames, it is a sign that there is a serious structural problem. This could happen when the ground shifts beneath the foundation. If the home is built on stumps, it may need to be restumped in certain or all areas. Slab heave can affect homes built on clay soils or concrete slabs. This happens when the soil beneath the slab expands because of moisture, lifting the slab and causing structural problems that require professional evaluation.
