The defects are listed. Now whose cost is each one? How cause, your contract and the contractor's defects period decide who pays to put them right.
📍 We serve KL, Selangor & Putrajaya.
Who pays for defect rectification after a renovation depends on what caused each defect and on what your contract says, not on who found it. Work done without reasonable care and skill is, as a starting point, the contractor's to put right at their cost. Faults caused by materials you supplied, by your own instructions, by later damage or by another trade may land elsewhere. Sort the list by cause first, then by contract term. To arrange a check of your contractor's work in the Klang Valley, see renovation inspection.
A contractor who quoted, priced and carried out the work is responsible for doing it properly. Under section 53 of the Consumer Protection Act 1999 there is an implied guarantee that services supplied to a consumer are carried out with reasonable care and skill, and that materials supplied with them are fit for their purpose. Many written renovation contracts add their own promise to make good defects that appear within an agreed period after handover.
So for the common run of findings, such as hollow tiles, poor falls to a floor trap, gaps in carpentry or patchy paint, the default position is simple: the contractor comes back and fixes it, and you do not pay again for work you already paid for. The arguments start at the edges, where the cause is mixed or the contract is unclear.
Before you discuss money with anyone, go through the findings and put each item in one of these groups. The cause, more than the defect itself, decides whose cost it is:
| Cause of the defect | Who usually bears the cost | What can change that |
|---|---|---|
| Poor workmanship by the contractor or their subcontractor | The contractor | Usually little; your contract is with the main contractor, not their subcontractor |
| Materials the contractor chose and supplied | The contractor | A written choice by you of a cheaper option after being warned |
| Materials you bought and handed over | Often you, or your supplier | Whether the contractor should have spotted and raised the problem before using them |
| Your instruction against the contractor's advice | Often you | Whether the advice was given, and given in writing |
| Damage after handover, wear or misuse | You | Proof the damage traces back to how the work was done |
| Another trade you hired directly | That trade, not the main contractor | Who was responsible for coordinating the trades |
| An original building defect the renovation exposed | Not the renovation contractor, as a rule | Whether their work made it worse |
A private renovation contract can set its own rules on defects, and those rules matter as much as the general law. Read it for these terms before you decide what to ask for:
If the contract says nothing about defects, you are not without rights; the implied guarantee still applies. If you are writing the next one, the renovation contract guide explains these clauses, and a right-to-inspect clause makes the check itself part of the agreement.
Owners of newer homes often mix up two different defect periods. A developer's defect liability period comes from the sale agreement for a new home. A renovation contractor's defects period, if there is one, normally comes from your renovation contract or quotation. They run separately and cover different work.
That has a practical cost. Renovating a home while the developer's period is still running can make it harder to claim from the developer for items your contractor has since changed, which the guide on renovating during the DLP explains. When an inspection finds a defect in a newer home, ask first whether it sits in the developer's original work or in the renovation, because the answer decides who you approach.
Buying your own tiles, adhesive, sanitary ware or paint saves money, but it moves risk onto you. If a defect comes from the material itself, such as a tile batch that is out of square or a mixer with a faulty cartridge, the contractor will say it is not their workmanship, and they may be right. Your claim may then lie with the shop or the brand, so keep the receipt, the box labels and the batch numbers.
The line is not always clean. A careful tradesperson is expected to notice an obvious problem with a material before fixing it in place, and to raise it. Whether a contractor should have stopped and asked is a question of fact for each job, so look at the messages from the time the material arrived.
Real defects are often shared. A leak below a new bathroom can involve the plumber's joint, the waterproofer's membrane and the tiler's grout. Water marks on a new ceiling can come from the unit above. Scratches on a new floor can be the carpenter's, the painter's or the movers'. Where several trades worked under one main contractor, that contractor usually answers to you for all of them and sorts it out with their subcontractors.
Where you hired the trades yourself, you are the coordinator, and each trade answers only for its own work. That is when the order of work and stage records matter most. The guide to a ceiling leak after renovation works through one of the most common shared cases.
Section 60 of the Consumer Protection Act 1999 gives a consumer the right, where a failure can be remedied, to require the supplier to remedy it within a reasonable time. In practice that means a written request, item by item, with the cause and the contract term beside each one, and a proposed date.
| Step | What to send or do | Why |
|---|---|---|
| List the items | Each defect, its location and its likely cause | The contractor can answer item by item |
| Cite the promise | The quotation line, drawing or defects clause it breaks | Moves the talk from opinion to agreement |
| Propose dates | A date for each fix and who will be on site | Section 60 refers to a reasonable time |
| Hold the right sum | Keep back a fair share of what is still unpaid | Gives both sides a reason to finish |
| Re-check the fix | Look again before you release that money | A patch over the cause is not a fix |
Holding back money only works if it is fair and tied to the items. The guide on releasing a retention sum explains how to link a release to a re-check.
Section 60(3) of the same Act says that if the supplier refuses or neglects to remedy the failure within a reasonable time, the consumer may have it remedied elsewhere and recover the reasonable costs from the supplier. Under the Contracts Act 1950, section 74, compensation for a breach covers loss that naturally arose from it, not remote or indirect loss, and the means of remedying the breach is taken into account.
Two practical points follow. Give the contractor a real chance to fix before you bring in someone else, and keep the evidence of the defect, the repair quotes and the invoices. Whether the cost of the inspection itself, or a higher repair price elsewhere, can be recovered is a question for the Tribunal or a lawyer; it depends on the facts. For the formal routes, see the guide on a contractor who won't fix defects.
Two kinds of defect need extra care before anyone talks about cost. An item that points to the electrical installation, such as a breaker that keeps tripping or a socket that is warm to the touch, should not be patched by whoever is cheapest. Any repair or change to the electrical installation must be done by an electrical contractor registered with Suruhanjaya Tenaga. Ask the original contractor who did the electrical work and whether they were registered, because that affects who is answerable.
A crack that keeps widening, or a sagging beam after a wall was removed, is a different question again. A crack, sagging beam or removed wall that may affect the structure needs a professional engineer's assessment. Who pays for that assessment, and for any repair it recommends, depends on whether the renovation caused the problem.
