My renovation contractor did defective work. Can I sue in Malaysia?

Leaking bathrooms, cracked tiles, wiring that trips, a kitchen half-built while the contractor stops answering calls: renovation disputes are among the most common consumer complaints. The right route depends on your contract, the amount and whether you are a consumer.

Step 1: Read your contract and quotation

Check what was agreed:

• the scope of work and materials;
• the price and payment schedule;
• the completion date and any delay clause;
• any defects liability period or warranty;
• how disputes must be resolved (for example arbitration).

Under the Contracts Act 1950, an agreement can be binding even if it is only a quotation accepted by WhatsApp. Messages that set out the scope and price are important evidence.

Step 2: Document everything

• Photographs and videos of each defect, with dates.
• A numbered defect list describing each problem and its location.
• Payment records: receipts, bank transfers, invoices.
• Messages with the contractor about the work and any promises to fix it.
• If possible, a report from an independent professional, such as an architect, engineer or qualified contractor, describing the defects and the cost of rectification.

Step 3: Give written notice to rectify

Send the contractor a letter or message listing the defects and giving a reasonable deadline to fix them. Keep it factual. If they fail to act, you may be entitled to engage another contractor and claim the cost, but take advice before doing so, and keep the evidence first.

Step 4: Choose the right forum

Route	When it may fit
Tribunal for Consumer Claims (TTPM)	You are an individual consumer, the claim is up to RM50,000, and it arose within three years. Low cost and designed for consumers.
Small claims	An individual claiming RM5,000 or less in the Magistrates' Court. See small claims.
Magistrates' or Sessions Court	Larger or more complex claims, or where you are not a consumer (for example a business renovation).
CIPAA adjudication	Payment disputes under written construction contracts. Section 3 of the Construction Industry Payment and Adjudication Act 2012 excludes contracts made by a natural person for work on a building of less than four storeys wholly intended for that person's own occupation.
Arbitration	If your contract requires it.

According to the Tribunal's official page, it hears claims for loss arising from the purchase of goods and services under the Consumer Protection Act 1999, not exceeding RM50,000 and accruing within three years. A person who buys services for business purposes or in a company's name is not a consumer.

What can I claim?

Depending on the evidence: the cost of rectifying defects, the cost of completing unfinished work above the agreed price, refunds for work not done, and other losses caused by the breach. You must take reasonable steps to limit your loss.

What if the contractor sues me for unpaid balance?

Contractors sometimes claim the outstanding balance. Your defects evidence can support a defence and a counterclaim. See received a writ.

What should I prepare?

• Contract or quotation and variation orders.
• Photographs, videos and the defect list.
• Payment records.
• The independent report, if any.
• The contractor's company or business registration details.

Common mistakes: paying in full before completion, demolishing defective work before documenting it, withholding payment without a clear contractual basis, and posting accusations online that may be defamatory.

When to speak to a lawyer

If the amount is significant, the contractor has abandoned the work, or you are being sued for the balance. You can contact us; every case depends on its facts.

Frequently asked questions

Do I need a lawyer at the Tribunal for Consumer Claims?

The Tribunal is designed for consumers to attend themselves. Advice beforehand can still help.

Can I withhold the final payment?

Possibly, if the contract and the defects justify it, but withholding without a basis may expose you to a claim. Take advice.

The contractor has disappeared. What now?

Check the business or company registration, send notice to the registered address, and consider your claim options. Recovery depends on the contractor having assets.

Is a WhatsApp quotation a contract?

It can be, if both sides agreed to the scope and price.

Can I report the contractor to the police?

Poor workmanship is usually a civil matter. A police report may be relevant only if there was dishonesty from the start.
