The Most Common Building Defects in Sydney: What to Look Out For
Sydney’s skyline is a testament to its recent construction boom. While this growth has been exciting, the rush to build has sometimes come at a cost. Construction defects are becoming more common, making it crucial for property buyers and owners to stay informed. Understanding these potential flaws will help you spot problems during inspections, empower you in negotiations with sellers or developers, and allow you to plan for responsible future maintenance.
In this blog, we’ll delve into the most common building defects found in Sydney. By arming yourself with this knowledge, you can make better-informed decisions and protect your investment in Sydney’s dynamic property market.
Water Leaks and Waterproofing Issues
- Sydney’s Weather: Sydney receives significant rainfall, and its coastal location means salt air can be a factor. These conditions put continuous stress on a building’s waterproofing systems.
- Common Areas: Balconies, roofs, windows, and bathrooms are hotspots. Poor sealing, installation errors, or age-related deterioration can all lead to leaks.
- Consequences: Water intrusion can cause major issues including mold growth (a health hazard), rotting timber frames, and even structural damage if left unchecked.
Concrete Cancer (Concrete Spalling)
- Definition: Concrete cancer occurs when the steel reinforcement within concrete begins to rust. This rust expands, cracking the concrete and causing it to flake or “spall”.
- Susceptible Areas: Particularly common in balconies, exposed facades, and any concrete element often exposed to water or salty air.
- Seriousness: Concrete cancer requires urgent attention. If neglected, it compromises the structural integrity of the building with potentially large repair costs.
Cracking
- Cosmetic vs. Structural: Minor hairline cracks often stem from natural building settlement and are usually harmless. Larger, widening cracks, or those accompanied by uneven floors or sticking doors/windows can indicate serious structural movement.
- Common Areas: Cracks can appear on walls, ceilings, floors, and around windows and doors.
- Causes: Structural movement can be caused by foundation issues, reactive soils, or simply poor construction practices.
Electrical Faults
- Potential Dangers: Electrical malfunctions pose serious risks of electrical shocks and fire hazards.
- Licensed Electricians: Always use qualified electricians for any electrical work. Never attempt DIY fixes on wiring.
- Common Issues: Outdated wiring that can’t handle modern loads, overloaded circuits, and unsafe DIY modifications are frequent culprits of electrical problems.
Plumbing Problems
- Leaky Pipes and Faucets: Causes include worn seals, corrosion, or poor installation. These leaks may go undetected for some time, leading to water wastage and possible hidden damage.
- Drainage Issues: Blocked or broken pipes cause backups and overflows. Common culprits are tree roots, improper disposal of waste, or aging pipes.
- Consequences: Water damage can be extensive and expensive, with the need to replace flooring, walls, and even structural components in severe cases.
Additional Points to Consider
- Roof Defects: Missing or broken tiles, damaged flashing, and gutter problems allow water intrusion with similar consequences to waterproofing issues.
- Strata/Apartment Buildings: These properties face unique challenges, often sharing common areas and building elements where defects can create complex disputes over responsibility and repairs.
