Renovation noise is the complaint most people expect when a neighbour starts hacking. Physical damage is less common but far more stressful: a new crack along your wall, water dripping through your ceiling after upstairs replaces their bathroom, or tiles that pop after heavy drilling next door. Dealing with neighbour renovation damage calmly and methodically is the best way to get it fixed without ruining the relationship next door.
This guide is general information, not legal advice. For significant damage or a stalled dispute, consider speaking to a lawyer, and check current rules with HDB, your MCST, BCA or the relevant tribunal.
Who Is Usually Responsible
In general, the person whose works caused the damage is responsible for making it good. In practice, that usually means:
- The neighbour (the flat or unit owner) who commissioned the renovation, since they are responsible for works carried out in their home.
- Their renovation contractor, who may be liable for negligent work. Many contractors carry public liability insurance for exactly this situation.
You do not usually need to work out how the neighbour and their contractor split the bill. Your claim is generally with the neighbour, who can then pursue their contractor. That said, a cooperative contractor often fixes small damage directly, which is the fastest outcome.
Responsibility is less clear when damage could have several causes. An old crack can widen during works, or a ceiling leak might come from ageing pipes rather than new tiling. This is why evidence matters so much.
Document the Damage Properly
Good documentation makes everything that follows easier, whether you settle informally or end up at a tribunal.
- Photograph and video the damage as soon as you notice it, with timestamps. Include a ruler or coin for scale on cracks, and wide shots showing location.
- Record when it appeared relative to the renovation schedule. Note the dates of hacking, drilling or wet works next door.
- Keep a log of anything that changes, such as a crack lengthening or a leak worsening after showers upstairs.
- Check for pre-existing records. If you took photos when you moved in, or a pre-renovation condition survey was done, these are valuable.
- Get a professional opinion for anything beyond cosmetic damage. A contractor’s quote helps show repair cost; for structural concerns, a professional engineer’s assessment carries weight.
- Keep all communications in writing. Follow up any conversations with a short message summarising what was agreed.
If you know renovation is about to start next door, it is worth photographing your shared walls, ceilings and floors beforehand. Some condo managements and contractors arrange condition surveys for exactly this reason.
How HDB and Your MCST Fit In
The right authority depends on where you live.
HDB flats. HDB regulates renovation works in flats, including which works need a permit and that contractors are registered on its Directory of Renovation Contractors (DRC). You can check a contractor using our guide on checking HDB’s DRC list. If you suspect unauthorised works, such as hacking a wall that should not be touched, report it to your HDB Branch. For ceiling leaks between flats, HDB has guidance on how upper and lower flat owners share responsibility for investigation and repair, and may help assess the cause. HDB does not generally act as your claims agent for compensation, though. Check HDB’s website for current policies.
Condominiums and other strata properties. The MCST (Management Corporation Strata Title), usually through its managing agent, sets renovation by-laws. Owners often pay a renovation deposit, which may be used to repair damage to common property. Damage to your own unit is a private matter between you and the neighbour, but management can help with access, CCTV footage and facilitating discussion.
Structural concerns. If you see serious cracking in structural elements, report it promptly. BCA (the Building and Construction Authority) oversees building safety, and HDB or the MCST should be told about anything affecting the building’s structure.
For leak-related damage, our waterproofing and wet works guide explains why bathroom renovations upstairs are a common culprit.
Your Routes to Getting It Fixed
| Route | When to use it | What to expect |
|---|---|---|
| Talk to the neighbour directly | First step for most damage | Fastest; contractor may repair it |
| Insurance claim | Your home insurance or their contractor’s liability cover | May pay for repairs; check policy wording and excess |
| Community Mediation Centre | Talks have stalled but both sides are willing | Neutral mediator, voluntary, low cost |
| Small Claims Tribunals | Claim for repair costs within the tribunal’s limits | Simpler process, no lawyers needed |
| Strata Titles Boards | Condo disputes, including some inter-unit leaks | Specialist body for strata matters |
Speak to your neighbour first. Many people do not realise their works caused damage. A calm conversation with photos, followed by a written summary, solves most cases. Agree on who will repair, when, and how access will work.
Check insurance. Your home insurance policy may cover some damage, and your insurer may pursue the neighbour or contractor afterwards. Ask the neighbour for their contractor’s insurance details. Policy wording and excesses differ, so read yours carefully.
Try mediation. The Community Mediation Centre offers mediation for neighbour disputes. It is voluntary and focuses on reaching an agreement both sides can live with.
Go to a tribunal if needed. The Small Claims Tribunals hear claims for damage to property up to set financial limits, without lawyers. The Community Disputes Resolution Tribunals handle certain neighbour disputes involving interference with your enjoyment of your home. For strata properties, the Strata Titles Boards can hear certain disputes, including some involving leaks between units. Check the current limits and filing procedures on the official sites before filing.
Tips for Keeping Things Civil
- Assume good faith at first. Most neighbours want to fix it once they see evidence.
- Avoid confrontation with workers on site. Talk to the owner or the contractor’s supervisor.
- Do not withhold access to your unit for inspection or repairs without good reason, as it slows everything down.
- Get repair agreements in writing, including timelines and who pays for what.
- Keep the bigger picture in mind. You will likely live next to this neighbour for years.
