How to inspect a new home for water damage at handover, which tests to ask for on the day, and why the dated record you build then is what makes a later claim provable.
Handover conversations are full of dates, and two of them get confused constantly. This page exists partly to keep them apart, because mixing them up is the single most expensive mistake an owner can make in the first month of ownership.
Read the start date in that sentence and take it literally. The period runs from the date the purchaser takes vacant possession — not from the date on any other document in the file. Write that date down on the day it happens.
The other date is the CCC, short for the certificate of completion and compliance. It matters, but it matters for a deadline of its own rather than for the period quoted above, and that deadline is stated precisely on our page about taking a new-build water leak claim to the tribunal. Keep both dates in your file and do not let anyone merge them. If you want the wider handover picture, vacant possession and handover covers the process, and late vacant possession covers what happens when it slips.
On handover day the property is in a state it will never be in again: empty, unfurnished, unlived-in, and with nobody able to suggest that you caused anything. A month later there is a sofa against the wall you needed to photograph, a rug over the floor that ponds, and a developer who can reasonably ask whether the damp patch appeared before or after your renovation. None of that is bad faith. It is just what happens when evidence is not captured at the only moment it is clean.
So the goal of a handover inspection is not to win an argument on the day. It is to leave the property holding a complete, dated record of its condition. If nothing is wrong, you have lost an afternoon. If something is wrong, you have the one thing that makes it provable months later, when the stain has spread and the memories have not.
An empty unit hides water in predictable places, because the same details get built last and tested least. Work through them in order rather than wandering. Take a torch, a bottle of water, a roll of tissue and a phone with plenty of storage.
| Where to look | What you are looking for | How to check it on the day |
|---|---|---|
| Bathroom and shower floors | Falls that do not run to the floor trap; a flat or reverse-graded screed | Pour water at the far corner and watch where it goes. It should reach the trap and leave nothing behind |
| Floor traps and pipe penetrations | Slow drainage, gaps around the pipe collar, unsealed sleeves | Run water and time it; look into the gap around every pipe with a torch |
| Ceilings below wet areas | Faint staining, patch repairs in fresh paint, a different sheen in one area | Torch held flat against the ceiling — raking light shows what flat light hides |
| Base of internal walls next to bathrooms | A darker band, blistered paint, soft or bulging skirting | Press it. Sound plaster is hard and quiet; damp plaster gives and sounds dull |
| External walls, inside face | Damp patches after rain, staining below window heads, salts on the surface | Inspect after a wet night if you can, and photograph the outside face directly opposite |
| Windows and sliding doors | Missing perimeter sealant, blocked or absent weep holes, a threshold set too low | Pour water into the track and watch whether it drains outward or inward |
| Balconies and yards | Falls running back toward the door; a threshold level with the internal floor | Pour water at the door line. It should run away from the room, always |
| Wet kitchen and yard areas | Trap positioned high, floor draining to a doorway, unsealed wall-floor junction | Same pour test, plus a look at the junction where the wall meets the floor |
| Air-conditioner points and trunking | Condensate drain falling the wrong way; an unsealed sleeve through the external wall | Check the sleeve from outside and look for staining below it |
| Top-floor ceilings and any roof over your unit | Staining at the perimeter, at penetrations, or along one line | Photograph the whole ceiling from each corner, torch raking across it |
| Ground-floor walls in landed property | A tide line low on the wall, salts, paint lifting at skirting height | Compare several walls — a defect is usually localised, a general pattern is something else |
| The water meter, before you leave | Movement while every tap and cistern is off | Close everything, photograph the meter, wait, photograph it again |

A moisture meter reading is a useful supporting observation and a poor conclusion on its own — readings shift with the material, the finish and the weather. Use it to decide where to look harder, not to declare a verdict.
New buildings are wet buildings. Concrete, screed and plaster all carry construction moisture for months, and some of what you see at handover is that drying out rather than a defect. Calling everything a leak weakens the items that genuinely are.
| What you see | Often is | What separates it from a real defect |
|---|---|---|
| White crystalline bloom on a wall or floor | Efflorescence — salts carried out as the build dries | It recurs after wiping only if moisture keeps arriving. See efflorescence in a new condominium |
| Water on a wall or window only in the mornings | Condensation on a cold surface | It appears without rain and dries as the day warms. See condensation versus seepage |
| A damp patch that only appears after heavy rain | Rain entering through the envelope | It tracks the weather, not the plumbing |
| A patch that is there constantly, wet or dry weather | A supply pipe, or water arriving from a unit above | It ignores the weather entirely — and the meter test tells you which |
| Freshly painted patch on an otherwise uniform ceiling | A repair that has already been made | Ask what was found and what was done, in writing, before you accept the unit |
Whichever it turns out to be, list it. A note that reads “white bloom on the store room floor, photographed, cause to be confirmed” is honest and it preserves the date. A list that only contains certainties is a list that leaves your best evidence out.
Keep the walkthrough video even if you never use it. Two years later it is the only thing that shows the condition of a detail nobody thought to photograph.
Write the list on the day while it is fresh, and write it so a stranger can act on it. Number every item. Give the room, the exact location within the room, what you observed, and the date. Reference the photographs by number. Keep water items grouped so they can be inspected together — a plumber and a waterproofing contractor visiting once is worth more than five separate visits.
Then submit it in writing, keep proof of delivery, and use the developer’s defect portal as well if there is one, screenshotting each submission and its reference number. Defect inspection and building defect inspection cover the general process; new house defects and the developer covers the follow-up.
Handover involves paperwork, and it is entirely reasonable to slow down at that point. Ask what each document is. Ask for a copy of everything you sign, on the day, not later. If you are being asked to confirm a condition and you have found defects, list them on the face of the document before you sign it, and photograph the signed version with your list on it.
If you are not sure what a document does or what signing it means for you, that is a question for the solicitor who acted on your purchase — they hold your file and they have read your agreement. It is a short question and it is much cheaper asked before the signature than after. Take the time you need — there is no reason to sign anything in a hurry.
You can bring somebody. An hour of a contractor’s time at handover buys you two things an untrained eye does not get: they know where these details fail, and their written finding carries weight that a homeowner’s photograph does not. It is most worth doing where the risk is concentrated — a top-floor unit, a unit with large balconies or planters, a landed house with flat-roof sections, or any unit where you already saw something you did not like on a site visit.
Ask for a written report rather than a verbal opinion, with photographs referenced in the text, a note of what was tested and how, and a note of what was inspected and found sound. The second half matters as much as the first: proving that something was checked and was fine on the day is exactly what protects you if it fails later. Buying a house with hidden defects covers the same principle for a resale purchase.
In a condominium that has a practical consequence for your handover walk. Some of what will affect your unit is not inside it — the roof above the top floor, the podium above a car park, the external face of your wall, the riser behind your bathroom. You will not be inspecting those on handover day, but you can photograph what you can see of them from your unit and from the ground, and you can note their condition in your file.
When something later arrives from one of those places, you will be dealing with the management as well as the developer. Inter-floor leakage is the page that covers that, common property defects covers building-wide items, and the developer-to-JMB handover covers what happens to the common property when a scheme is handed over.
That is why the handover record is worth an afternoon. Everything in that sentence turns on a defect becoming apparent, on the cause, and on written notice — and dated photographs taken while the unit was empty support all three. Water leaks inside the defect liability period is the companion page to this one: it covers what to do once a leak has actually appeared, including the notice, the sequence and what to do when the developer stalls. The general defect liability period guide covers non-water defects.
Most of the checklist above costs nothing but your time. Where it is worth paying is when something has already been found and you need the cause stated properly, or where the unit carries concentrated risk. These are our own prices (market estimate 2026, indicative Klang Valley applies only to the market rows below them):
| ClickBina service | Our price | What it covers |
|---|---|---|
| Leak detection & assessment | RM300 – RM800 per visit | waived if you proceed with the repair |
| PU injection — leaking bathroom ceiling | RM650 flat | one bathroom ceiling, includes the injection points |
| Bathroom re-waterproofing (non-hacking) | RM1,500 – RM3,500 per bathroom | existing tiles stay; coating over the screed |
| Work | Market range (2026, Klang Valley) | Notes |
|---|---|---|
| Cementitious slurry | RM6 – RM10 per sq ft | rigid; best on sound concrete |
| Flexible two-part membrane | RM8 – RM14 per sq ft | tolerates hairline movement |
| Liquid PU membrane | RM10 – RM18 per sq ft | seamless, the common flat-roof choice |
The second table is a market estimate for a first conversation (market estimate 2026, indicative Klang Valley), and it is there for one reason: so that if a developer’s contractor describes a remedial scope, you have a sense of whether it sounds proportionate to the defect. Bathroom waterproofing covers what a proper wet-area build-up looks like, which is also what you are checking for on the day.
ClickBina inspects and repairs water problems in new homes across Kuala Lumpur and Selangor. At handover we do the unglamorous part: pour tests, flow tests, a raking-light sweep, the meter, and a written finding with photographs that you can attach to a defect list. Detection and assessment is RM300 – RM800 per visit and is waived if you proceed with a repair. If nothing is wrong we will say so and you will have the record anyway.

This guide sets out what the wording we verified actually says, and what to do about it. It is information, not advice on your own matter. A specific dispute turns on your own documents, your own dates and your own facts, and needs a professional adviser who has read them — take that advice before you rely on anything here.
