Pipe and point schedule
Pipe material/specification, route, approximate extent, valves and every kitchen, bathroom, yard, heater or outdoor point included.
Whole-House Repiping Singapore
For HDB, condo and landed homes considering replacement or rerouting of multiple water-supply pipe sections. FixMove coordinates the survey and quote route; regulated plumbing is assigned to a PUB Licensed Plumber where required.
Quick answer: should you repipe the whole home?
Do not approve a full repipe from a leak photo alone. First confirm whether the problem is one local fitting, a concealed supply pipe, sanitary pipe, waterproofing or common-property source. If repeated failures or the wider pipe route justify replacement, request an itemised S$ project quote covering every water point, route, material, access, Licensed Plumber scope, testing and reinstatement. There is no responsible fixed whole-house package price before the site survey.
Local repair, partial reroute or whole-house repipe?
The lowest-disruption option that addresses the confirmed cause should be considered first. This comparison prevents a single leak from being sold automatically as a full-home project.
| Option | Better fit when | Scope boundary | S$ quote basis |
|---|---|---|---|
| Local repair | One fitting, joint or short pipe section has a confirmed defect and the surrounding route is serviceable. | Repair only the identified point; opening and finish repair are separate unless listed. | Itemised diagnosis, parts, labour, access, testing and reinstatement. |
| Partial reroute | One branch or inaccessible section is unreliable, while the rest of the home does not justify replacement. | Define start/end points, abandoned section, affected outlets and surface/concealed route. | Survey-based quote by route length, points, material, access, LP scope and finishes. |
| Whole-house repipe | Failures recur across sections, broader condition is a concern, or renovation makes coordinated replacement practical. | List every included supply point and every exclusion; sanitary pipes and waterproofing are not automatically included. | Project S$ quote after site survey, point schedule, route plan and reinstatement choices. |
What an itemised repiping quote should show
Access and protection
Surface or concealed route, openings, drilling limits, furniture protection, water isolation and occupied-home working constraints.
Regulated scope
The assigned PUB Licensed Plumber scope, plus any notification, plan, schematic, inspection or completion documentation that applies.
Testing and handover
Pressure or leak checks, flow checks, valve labels, defect close-out and any route record or handover document expressly included.
Finishes and other trades
Make-good limits for tiles, plaster, paint, waterproofing or carpentry; electrical, aircon and cabinet work listed separately.
Commercial terms
S$ price, taxes if applicable, payment stages, exclusions, assumed access, customer decisions and written variation approval rules.
Diagnosis and responsibility boundaries
- Supply pipe versus other sources: a damp wall or ceiling can come from a water-supply pipe, sanitary pipe, waterproofing, facade/common property or another unit. Repiping the supply network will not fix an unrelated source.
- Private versus common property: source evidence should be documented before deciding whether the owner, landlord, upstairs unit, MCST or Town Council route applies. FixMove can coordinate service scope but does not determine legal liability.
- Pipe work versus reinstatement: opening, tile replacement, waterproofing, plaster, paint and carpentry are not assumed to be included. The quote must name the trade and finish limit.
- HDB, condo and landed constraints: share the property type, management requirements, approved work hours, access and renovation status before the route and schedule are priced.
- Regulated work: FixMove does not represent every worker or every job as licensed. The actual work must be classified, and regulated water-service or sanitary plumbing is to be carried out by a PUB Licensed Plumber.
Whole-house repiping process
Send the property and failure history
Share HDB/condo/landed type, postcode, floor plan if available, number of wet areas, affected points, prior repairs and photos or videos.
Survey the source, route and access
Confirm whether repiping is justified, identify isolation points and obstructions, and compare local repair, partial reroute and full replacement.
Receive the itemised S$ quote
Review points, material, route, LP and documentation scope, protection, testing, finishes, exclusions, timeline dependencies and variation rules.
Confirm building and regulatory requirements
The appointed parties check applicable PUB, HDB or MCST requirements before regulated work or disruptive access begins.
Install, test and hand over the stated scope
Water-off windows, workmanship checks, functional testing, defect close-out and any finish reinstatement follow the accepted written scope.
Singapore rules to check before repiping
PUB classifies laying, installing, altering, repairing or replacing drinking-water pipes and fittings as water-service plumbing work, and says regulated water-service and sanitary plumbing works must be carried out by a PUB Licensed Plumber, except simple plumbing works. PUB also advises owners to discuss scope and cost, request itemised quotations and obtain at least three quotes. Read the PUB Plumbing Works requirements.
PUB's water-supply-services page covers notification, site plans, schematic drawings and completion certification for applicable water-service works. The appointed Licensed Plumber should confirm which requirements apply to the actual route and building. See PUB Water Supply Services.
For HDB homes, the current guideline says the water and sanitary plumbing works listed on that page do not require an HDB renovation permit, but remain subject to technical terms and conditions. It also cautions that concealed-pipe layouts are only a guide. Check the exact work against the HDB water and sanitary plumbing guidelines before drilling, opening or rerouting.
Whole-house repiping FAQ
How much does whole-house repiping cost in Singapore?
There is no responsible fixed S$ package before a site survey. The project quote should state the number of water points, pipe material and route, access or opening, isolation, Licensed Plumber scope, testing, disposal, reinstatement, exclusions and variation rules.
When is whole-house repiping more suitable than repairing one leak?
A full repipe may be considered when failures recur across different sections, the existing route or material has broader condition concerns, or renovation makes a coordinated replacement practical. One confirmed local defect may still be better handled as a local repair or partial reroute.
Can new water pipes be surface-run instead of concealed?
Sometimes. A surface route can reduce opening and make future access easier, while a concealed route may suit renovation aesthetics but adds coordination and reinstatement. The feasible route depends on structure, existing services, wet areas, building rules and the Licensed Plumber's design.
Does whole-house repiping require a PUB Licensed Plumber?
PUB states that regulated water-service and sanitary plumbing works must be carried out by a PUB Licensed Plumber, apart from simple plumbing works. Whole-home water-supply alteration or replacement should therefore be classified and scoped by the appointed Licensed Plumber.
Does an HDB whole-house repipe need a renovation permit?
HDB says the water and sanitary works listed on its guideline page do not require an HDB renovation permit but remain subject to technical terms and conditions. The exact repiping route, any opening or reinstatement and the contractor requirements must be checked against the current HDB rules before work.
Are tiles, paint and carpentry reinstatement included?
Only if the written quote lists them. Pipe work, openings, tile or wall repair, painting, carpentry removal and reinstatement are separate scopes unless expressly bundled with materials and finish limits.
How long does whole-house repiping take?
The schedule depends on the number of points, route, occupancy, access, approvals, material availability, water-isolation windows and reinstatement. Ask the itemised quote to state planned working days, water-off periods, dependencies and handover checks rather than relying on a generic duration.
