Riser pipes, facades, roofs and planter boxes — how to prove a common-property leak, report it properly and get the management body to fix it.
In a Malaysian strata scheme, common property is broadly everything not comprised in any individual parcel — the structural frame, roof, external facade, corridors, lift lobbies, service risers, planter boxes and the pipes and ducts that serve more than one unit. Under the strata management framework, the JMB (before strata titles are fully issued) or the MC (after) is generally responsible for maintaining and managing the common property, funded by the maintenance charges and sinking fund every owner pays. The exact boundary between your parcel and common property depends on your strata plan, so check before assuming — a pipe inside your wall may still be common property if it serves other units. Our JMB guide explains the whole framework, including where the money comes from and how decisions get made.
Some leaks are almost always common-property problems by their nature. Riser and soil pipes running through service ducts serve the whole stack; the roof membrane sits above the top-floor ceilings; the facade and its joints face the weather for every unit behind them; and corridor planter boxes are a notorious source of slow seepage into the adjacent unit’s wall. Water tanks and pump rooms add their own failure modes. How management bodies plan and fund these repairs is covered in our guide to JMB common area waterproofing.
| Common-property source | Typical symptom inside a unit |
|---|---|
| Riser / soil pipe in service duct | Damp wall or ceiling along the duct line, often on several floors |
| Roof membrane failure | Top-floor ceiling stains that worsen with rain |
| Facade cracks or failed joints | Damp on external-facing walls after storms |
| Corridor planter box | Persistent damp low on the corridor-side wall |
| Rooftop tank or pump room | Continuous seepage unrelated to weather |
Before you write to management — or blame the upstairs neighbour — read the clues. Location and timing narrow the source considerably, and pointing at the wrong party wastes weeks.
| Clue | Points towards |
|---|---|
| Stain directly below the upstairs bathroom, steady drip | Neighbour’s unit — see our upstairs bathroom leak guide |
| Damp worsens only during or after rain | Facade, roof or planter box — likely common property |
| Top-floor unit, ceiling stains | Roof membrane — common property |
| Wet patch tracking the service duct or riser line | Riser pipe — usually common property |
| Damp low on the corridor-side wall | Corridor planter or slab — common property |
| Constant leak regardless of weather or neighbour’s usage | Pressurised supply pipe — needs tracing |
Where the clues conflict, professional tracing settles it — our leak detection guide covers the methods, and the upstairs bathroom leak guide covers the neighbour-unit scenario in full. An independent source-identification report is also exactly what you will want attached to your complaint.
Verbal complaints at the management office evaporate. Put the complaint in writing — email is fine — addressed to the management office, stating your unit number, when the damp appeared, where it is, why you believe the source is common property, and what you are asking for: an inspection and repair of the source. Attach dated photos and any inspection report. Ask for a written acknowledgement and a timeline. Follow up in writing at reasonable intervals rather than relying on phone calls, and log every visit by the building’s technician, including what they said. This is not aggression — it is simply how a request becomes actionable, and it is the foundation of everything that follows if the leak is not fixed.
The strata management framework generally places the duty to maintain the common property in good repair on the JMB or MC — that is a large part of what your maintenance charges and sinking fund exist for. Repairs to a leaking riser, roof or facade are therefore normally management’s to arrange and fund, while damage inside your unit that results from their delay is a separate conversation that can involve the building’s insurance (see our strata insurance guide) or, ultimately, a tribunal claim. Be modest about legal certainties — the position depends on your strata plan, the by-laws and the facts — but the general principle that common property upkeep sits with management is the starting point of every conversation. Our JMB guide covers the duties and how committees actually operate.
If the matter ever reaches the Commissioner of Buildings or the tribunal, your case is your paper trail. Keep a simple chronology: date of each photo, each complaint, each acknowledgement, each site visit and each promise made. Photograph the damage on a regular schedule so worsening is provable, keep moisture or inspection reports, and keep quotes for the repair of your own damaged finishes. Save everything in one folder as it happens — reconstructing a two-year saga from memory is far weaker than a contemporaneous log. The single most valuable document is usually an independent inspection report identifying the source as common property, because it converts your complaint from opinion into evidence.
Most JMBs and MCs are not malicious — they are short of funds, quorum or urgency. Escalate in steps, in writing, keeping every rung documented: it is both fairer and more effective than jumping straight to threats. A typical ladder: repeat the written complaint referencing the earlier ones; write formally to the committee (not just the site staff) and ask for the item to be tabled; raise it at the AGM or EGM where it enters the minutes; lodge a complaint with the Commissioner of Buildings (COB) at your local authority, who oversees management bodies; and finally file at the Strata Management Tribunal. Parallel to all of this, keep protecting your unit and documenting the worsening — delay is management’s risk, not your obligation to absorb quietly.
The Strata Management Tribunal exists for exactly this kind of dispute — it is designed to be affordable, lawyers are generally not required, and it can order a management body to carry out repairs to common property and address related claims within its monetary jurisdiction. Filing is straightforward compared with court, but your outcome still turns on evidence: the chronology, the written complaints, the photos and the source-identification report. Our Strata Management Tribunal guide walks through who can file, what it costs, the process and what orders it can make — read it before filing so your claim is framed cleanly. In practice, a well-documented COB complaint or tribunal filing often prompts action before any hearing happens.
Tempting, and occasionally necessary — but risky without agreement. If you repair common property unilaterally and invoice the JMB, there is no guarantee of reimbursement: the committee may dispute the responsibility, the price, or the quality, and you may have spent real money for a promise that never arrives. The safer sequence is to get written agreement first — ideally a committee decision that you may proceed with a named contractor at an agreed price, with reimbursement or set-off confirmed. In a genuine emergency (active water into your unit), do what a reasonable owner must to limit damage, document the urgency and costs thoroughly, and pursue recovery afterwards — but understand recovery is an argument, not an entitlement. Never let a self-arranged repair destroy the evidence of the source before it is documented.
While responsibility is argued, protect what is yours. Move furniture and electronics away from the damp zone, run a fan or dehumidifier to slow mould, and treat any mould growth early. Interim measures inside your unit — catch trays, plastic sheeting, sealing a stained ceiling — are reasonable and do not weaken your position if documented. Your own contents or renovation policy may respond to the resulting damage even while the source remains management’s problem; our guide to water damage insurance claims covers how to document and file that claim properly. Keep receipts for interim measures — they may form part of a later claim against the management body.
ClickBina inspects leaks across Klang Valley condos and produces the independent source-identification reports that make a common-property complaint stick — moisture readings, photos, cause and an itemised repair scope you can hand to the JMB, COB or tribunal. Once responsibility is settled, we repair the damage inside your unit: PU injection for a leaking ceiling is RM650 flat for one bathroom ceiling, with plaster, sealing and repainting quoted itemised (indicative 2026, Klang Valley). WhatsApp us photos of the damp and we will tell you same-day what the likely source is and what an inspection would involve.
