Renovation Warranty and Defects After Handover in Singapore

The handover walk is when you catch what is wrong before the last payment and before the furniture arrives. What happens next is just as important: defects that show up after you move in, how you document them, and what your contract and any accreditation actually cover.

This guide is for the period after handover. It is general Singapore homeowner guidance. It is not a walkthrough of the handover day itself — use our renovation handover checklist for that — and it is not about HDB's defects liability on a new BTO flat, which we cover in the BTO key collection defect checklist.

Why defects show up after you move in

Some issues only appear once the flat is lived in. Soft-close hinges that stick after humidity builds, a hairline crack along a plaster joint once the aircon runs daily, a floor that creaks under a wardrobe that was not there at handover, or a sealant line that opens after the first hot shower week. None of that means you missed the walk. It means the flat is under real use.

What changes after move-in is leverage and evidence. Furniture covers edges, cabinets fill up, and "when did this start?" becomes harder to answer unless you kept a clear record from day one.

What to document at and after handover

Leave handover with more than a photo dump on your phone:

• A dated defects list that you and your contractor both acknowledged, with a target rectification date for each open item

• Warranty details in writing for carpentry and workmanship, plus manuals and warranty cards for appliances and fittings your firm supplied

• A final invoice that matches the quotation plus agreed variation orders

• Photos of every room empty, plus close-ups of any marked defects, with the date visible in the file name or metadata

In the first weeks after move-in, note new issues the same way: room, description, date first seen, photo with a coin or tape for scale. Send them in one written channel (email or WhatsApp) rather than scattered voice notes. Keep the thread. That record is what you rely on if a fix slips or a dispute starts.

Typical defect categories after move-in

Homeowners commonly raise:

• Carpentry — doors that no longer align, drawers that jam, laminate chips, soft-close failures, loose handles

• Finishes — paint touch-ups that flash under daylight, plaster cracks at joints, silicone gaps at wet-area junctions

• Floors — hollow-sounding tiles that were borderline at handover, vinyl edges lifting at skirting, creaks under new furniture loads

• Wet areas — slow drips under basins, sealant that pulls away, ponding that only shows after daily showers

• Electrical and lighting — loose switches, flickering cove lights, points that fail under normal load

Separate workmanship (how it was built) from wear and misuse (chips from movers, burns, water left standing). Also separate defects your renovation firm owns from building-side issues that may need a PE, a licensed electrician, or HDB/MCST attention — for example structural cracks, persistent seepage from the unit above, or shared-stack problems.

How to raise defects in writing

• Check your contract for the defects or warranty window, what is covered, and how notice must be given.

• Send one clear list — room, item, photo, date first noticed — and ask for a proposed rectification date.

• Allow reasonable access for the contractor to inspect and fix; note visits and what was done.

• If nothing moves, escalate in writing to the firm's stated contact, then to any dispute path named in the contract or accreditation scheme.

Stay factual. A dated list with photos travels further than an angry message with no attachment. If you are still choosing a firm, ask at the consult how they handle defects after handover — the same habit as reading payment stages carefully in our renovation payment schedule guide.

What CaseTrust standard accreditation generally signals

CaseTrust is a Consumers Association of Singapore (CASE) trust mark for renovation businesses. It is a filter and accountability signal, not a ranking badge and not a promise that every project will be defect-free. Our plain-language guide to what CaseTrust renovation accreditation means covers the basics; the points that matter after handover are:

• Workmanship warranty under the scheme — CaseTrust's public materials for accredited renovation businesses state that businesses shall provide homeowners a workmanship warranty for a period of 12 months from the completion date of the works, with necessary rectification if defects arise from those works during that period, subject to the contract's terms and conditions. That is a scheme expectation, not a substitute for reading your own signed contract.

• Dispute resolution — accredited businesses are expected to have a clear complaints process. If a dispute cannot be resolved and the homeowner requests mediation at the CASE Mediation Centre, a CaseTrust-accredited business must attend the mediation session CASE arranges.

• Contract and payment clarity — the scheme points firms toward a standard renovation contract with progressive payments, transparent pricing and defined obligations, plus deposit/prepayment protection arrangements described on CaseTrust's own pages.

Blackwoods Interior holds CaseTrust standard accreditation for Renovation Businesses (the standard tier, not Gold), valid through 28 April 2028. We do not invent Gold status, rankings or awards. Specific Blackwoods warranty periods, retention amounts and payment terms belong in your written quotation and contract once confirmed — this post does not invent them.

What is not covered — and when to call a specialist

Accreditation and a workmanship warranty do not usually mean:

• Damage from misuse, poor maintenance, or third-party movers and other trades after handover

• Wear and tear that is normal for the material and the climate

• Issues outside the renovation scope in your contract

• Structural, facade or neighbour-unit problems that need a professional engineer, a licensed specialist, HDB or your MCST

If a crack looks structural, if water appears to come from another unit or a common stack, or if an electrical fault repeats after a simple fix, stop guessing and get the right licensed professional. Your renovation firm can often help diagnose whether an item sits inside their works; they should not be asked to certify work they did not do.

Tie it back to the handover walk

The cleanest aftercare story starts on handover day: one signed defects list, warranty paperwork in hand, and photos of the empty flat. Use the handover checklist before final payment, keep raising new items in writing after you move in, and treat CaseTrust as one verified trust layer — not a shortcut past reading the contract. If you are still shortlisting firms, our guides on quotation red flags and choosing a reliable renovation company are useful companions.
