The most important credential for any plumber in Singapore is a PUB (Public Utilities Board) licence. Only PUB-licensed plumbers are authorized to carry out water service plumbing works. Hiring an unlicensed plumber is not only risky — it's actually an offence under Singapore law.

Beyond licensing, look for plumbers with strong Google reviews (4.0+ stars with at least 10 reviews), ACRA business registration (indicating a legitimate company), and clear pricing — reputable plumbers provide upfront estimates before starting work.

Response time matters too, especially for emergencies. Many Singapore plumbers offer 24/7 services, but verify this before you need it. Finally, check if they offer a warranty on their work — most reliable plumbers provide at least a 30-day warranty on labour.

Prices are estimates as of 2026 and may vary based on scope, urgency, and property type. Get exact quotes for free.

HDB flats are the most common property type serviced. HDB plumbing systems are relatively standardized, making repairs and replacements straightforward. However, older HDB blocks (pre-1990s) often have galvanized iron pipes that are prone to corrosion and may need full replacement. Typical HDB plumbing jobs range from S$60 for basic unclogging to S$600 for toilet bowl replacement.

Condominiums often have more complex plumbing layouts, especially in newer developments with concealed pipes and rain showers. Some condos require management approval before plumbing works can begin. Expect to pay 10-20% more than HDB rates due to the added complexity and access restrictions.

Landed properties have the most extensive plumbing systems, often including outdoor taps, garden irrigation, and multiple bathrooms. Water heater installations and pipe replacements in landed homes are typically 20-40% more expensive than HDB due to the larger scale and longer pipe runs.

No PUB licence: This is the number one red flag. Always ask for their PUB licence number and verify it. Unlicensed plumbers cannot legally perform water service works in Singapore.

No upfront pricing: Reputable plumbers provide estimates before starting work. Be wary of those who refuse to quote or give vague "we'll see" answers — this often leads to surprise charges.

Pressure to replace instead of repair: Some plumbers push for expensive replacements when a simple repair would suffice. Get a second opinion if you're told your entire system needs replacing.

No warranty: A plumber who doesn't stand behind their work is a red flag. Most reputable companies offer at least 30 days warranty on labour.

Cash-only, no receipt: Legitimate businesses issue proper invoices. Cash-only operations with no documentation make it difficult to claim warranty or dispute charges later.
