Question 1

How do I know if a crack in my building is structural or just cosmetic?

Accepted Answer

Structural cracks are typically wider than about 3mm, run diagonally, pass through load-bearing elements like beams or columns, and often appear alongside other signs such as misaligned doors or windows. Cosmetic cracks are usually thin hairline cracks that follow render joints or paint lines and don't affect the underlying structure. If you're unsure which you're looking at, treat it as structural until a professional inspection confirms otherwise.

Question 2

What causes concrete spalling and exposed, corroded rebar?

Accepted Answer

Spalling starts when water and chloride penetrate through cracks or inadequate concrete cover and reach the embedded steel reinforcement, causing it to corrode. Corroded steel expands to several times its original volume, and that expansion cracks and pushes off the surrounding concrete cover, exposing the rebar. The process tends to accelerate once it starts, since exposed rebar corrodes faster than protected steel.

Question 3

Is spalling concrete a safety hazard that needs urgent repair?

Accepted Answer

Yes, spalling concrete can pose a falling debris risk, particularly at height or above walkways, car parks and other areas with pedestrian or vehicle traffic. Even where the immediate area looks contained, the underlying corrosion is usually more extensive than what's visible on the surface. Prompt assessment and, where needed, temporary protection measures are advisable while a full repair is scoped.

Question 4

What is the defects liability period and how long does it last?

Accepted Answer

The Defects Liability Period (DLP) is a fixed window after handover, commonly 24 months under standard Malaysian Sale and Purchase Agreement terms, during which the developer is obligated to rectify defects reported by the purchaser. It typically covers defects related to workmanship, materials, and non-compliance with the agreed specification, rather than damage caused by the owner's own actions. The exact duration can vary slightly depending on the specific SPA and property type.

Question 5

What are early warning signs that a building facade needs repair?

Accepted Answer

Hairline cracks, discolouration or staining, loose or bulging tiles, and small pieces of debris on the ground below are early signs that a facade should be professionally inspected. These signs often appear gradually and can be easy to miss from ground level, which is why periodic close inspection matters even when nothing looks obviously wrong. Catching these early typically keeps the repair scope, and cost, smaller than waiting for visible spalling or larger material loss.
