Construction Warranties: What They Cover and What People Assume

Warranty expectations cause more post-handover friction than the defects themselves. Six beliefs examined.

After handover, the word warranty is used to mean almost anything: a period, a promise, a product guarantee or a general sense that the builder remains responsible. These meanings are different, and the confusion between them is where post-handover disputes begin.

How to test a claim like this

Test any warranty claim by asking three questions: who issued it, what exactly does it cover, and for how long. A warranty that cannot answer all three is a conversation, not a protection.

Myth 1: The contractor is responsible for everything for ten years

Reality: Liability periods differ by type of defect and by what the contract provides. Structural liability, contractual defects liability and product warranties are distinct, with different durations and different routes to enforce them.

How to check it yourself: Read the defects clause in your contract and collect the product warranties separately, since they are issued by manufacturers rather than by the contractor.

Myth 2: A warranty covers normal wear and tear

Reality: Warranties cover defects in materials or workmanship, not deterioration from use, lack of maintenance or damage caused after handover.

How to check it yourself: Ask whether the failure would have occurred had the item been correctly installed and maintained. That distinction is what determines whether it is a defect.

Myth 3: If the contractor disappears, the warranty is worthless

Reality: Contractual obligations may become hard to enforce, but product warranties from manufacturers remain valid and are often more useful for equipment, waterproofing systems and appliances.

How to check it yourself: Keep manufacturer warranties, installation certificates and product documentation in your handover file, separate from the construction contract.

Myth 4: Reporting a defect late does not matter as long as it is within the period

Reality: Many warranties require prompt notification, and delay can both weaken the claim and worsen the damage, particularly with water-related defects.

How to check it yourself: Notify in writing as soon as a defect appears, with dated photographs, regardless of when you expect it to be addressed.

Myth 5: Accepting a repair ends the matter

Reality: A repair that does not address the cause often means the defect returns. Whether the warranty period restarts for the repaired element depends on the terms.

How to check it yourself: Ask what caused the failure and what the repair changes. A repair without a diagnosis is a delay, not a remedy.

Myth 6: Maintenance is optional while under warranty

Reality: Equipment warranties frequently require documented servicing, and failure to maintain can void cover precisely when you need it.

How to check it yourself: Read the maintenance requirements for air conditioning, pumps and lifts, and keep service records from the first year.

What this changes in your decision

• Collect product warranties at handover, not when a failure occurs.
• Report defects in writing with dates and photographs.
• Keep maintenance records for any equipment under warranty.
• Ask for the cause, not only the repair, when a defect is addressed.
• Understand which obligations sit with the contractor and which with manufacturers.
