The 7 Most Common Defects Found During Pre-Purchase Inspections

When buying a property, identifying common defects with a pre-purchase building and pest inspection is crucial to ensure you’re making a sound investment. Many homes may have hidden defects that could affect your safety and long-term value. 

Ironbark Building and Pest specialises in uncovering these issues through thorough local building and pest inspections in north Brisbane suburbs including Albany Creek, Nudgee, Chermside, Strathpine and surrounds.

From structural concerns to signs of termite damage, knowing what to look for helps you make informed decisions before finalising your purchase. In this article, we’ll explore seven of the most common defects found during a Brisbane building and pest inspection, helping you understand what may be lurking beneath the surface.

1. Leaking Bathrooms

A common defect discovered during a building and pest inspection in Brisbane is leaking bathrooms. This often stems from issues such as faulty waterproofing, deteriorated seals, or damaged grout.

Water can seep into surrounding structures, leading to significant moisture damage, including rot and mould. Over time, this can weaken the structural integrity of the house. It’s essential to identify leaking bathrooms early, as repairs can be costly if the damage spreads.

A professional should assess the leak, fix any seals, and address any water damage found.

2. Cracked Brickwork

Cracking in brickwork is another frequent defect found during building inspections in Brisbane. These cracks may occur due to ground movement, poor construction, or changes in the building’s foundation.

While small cracks might seem insignificant, they can widen over time, leading to structural problems. Larger cracks may allow water to seep through, causing internal damage and weakening the walls. It’s important to engage a qualified professional to assess whether the cracks require repair or further structural reinforcement.

3. Rusted Steel Supports

In some homes, steel support posts may show signs of rusting, particularly around the base where they come into contact with moisture. This defect can compromise the stability of the entire structure, as rust weakens the integrity of the steel.

If not addressed promptly, rusted supports can lead to costly repairs or even replacement. Protecting steel supports from moisture and ensuring they are properly treated can prevent long-term issues, so it’s crucial to spot this defect early.

4. Loose Balustrades on Decks

Loose balustrades are a safety defect often found during inspections, particularly on older decks. Balustrades that are not securely attached pose a significant risk, as they may fail if leaned on, leading to potential falls and injuries.

This defect is particularly important in homes with elevated decks or areas with high foot traffic. A qualified carpenter or builder should be consulted to securely reattach and reinforce the balustrades, ensuring they meet safety standards for all occupants.

5. Termites in Stored Timber

Stored timber in yards can attract termites, leading to infestations that may spread to the home itself. Termites are a serious defect because they can silently destroy wooden structures, weakening a building’s framework.

Often, homeowners are unaware of termite activity until significant damage has occurred. Pre-purchase inspections focus on identifying signs of termites early on, particularly in stored timber or gardens close to the home.

Removing this timber and treating the area can prevent future infestations.

6. Drummy Tiles

Drummy tiles are a defect where they sound hollow when tapped, indicating poor adhesion to the underlying surface. This can result from moisture, improper application, or age-related deterioration.

Left unchecked, drummy tiles may eventually crack and fall away, leading to unsightly damage and potential water ingress. Addressing this defect requires a qualified tilers to assess the extent of the issue and undertake any necessary repairs to ensure the surface remains intact and secure.

7. Cracked Concrete Slabs

Cracks in concrete slabs are a common defect found in many Brisbane homes. These cracks can develop due to ground movement, shifting foundations, or poor installation.

Left untreated, cracks in concrete slabs can grow, leading to water ingress, further damage, and potentially costly repairs. While hairline cracks may not pose an immediate threat, it’s important to monitor them and consult a professional to determine whether reinforcement or repair is needed to maintain the slab's integrity.
