Key takeaways
- Most drain cleaning jobs in Singapore land between SGD 80–SGD 800 — known locally as blocked drain / choke clearing.
- Sanitary plumbing works in Singapore must be carried out by PUB-licensed plumbers under the Sewerage and Drainage Act; town councils maintain common sewer stacks in HDB estates and MCSTs in condos. Clearing a simple choke is not licensable work, but repairs are.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Singapore typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a drain cleaning pro in Singapore
- For sanitary system repairs, use a PUB licensed plumber — sanitary works in Singapore are regulated; simple choke clearing can be done by handyman services
- In HDB flats, check whether the blockage is in the common stack — common-property chokes are the town council's responsibility, not yours
- Get a fixed price for the choke clearing before the visit
- Ask whether they carry proper augers/jetters, not just plungers
- For condos, report shared-stack issues to the MCST/managing agent first
- Get a receipt; recurring chokes justify a camera inspection
Red flags
- Very cheap 'choke clearing' ads that escalate on-site
- No fixed quote before starting
- Attempting sanitary pipe repairs without a PUB licensed plumber
- No receipt

Frequently asked questions
Who is responsible for a blocked drain — homeowner, neighbour, or utility?
Generally you own the pipes within your property boundary, while shared or public sewers are the utility's (or body corporate's) problem. If sewage backs up from a shared line, report it to the utility before paying a private contractor — it may be cleared free.
Can chemical drain cleaners fix a blocked drain?
Caustic supermarket products sometimes clear light soap/hair partial blocks, but they don't touch grease plugs or roots, they damage older pipes and seals, and they make the drain hazardous for the plumber who eventually opens it. For a fully blocked drain, go mechanical.
What causes most blocked drains?
Kitchen lines: grease and food solids. Bathrooms: hair and soap scum. Toilets: wipes (including 'flushable' ones) and sanitary products. Outside: tree roots entering pipe joints and silt. Knowing the likely cause helps the plumber bring the right machine first visit.
When is a CCTV drain survey worth paying for?
After a second blockage in the same line, before buying a house, or when you suspect root intrusion or a collapsed pipe. The camera shows exactly what and where the problem is, so you fix the cause instead of paying for repeat clearances.
What is the difference between snaking and hydro jetting?
A drain snake (electric eel/auger) bores a hole through the blockage — fast and cheap, but debris and grease remain on pipe walls. Hydro jetting scours the full pipe diameter with high-pressure water, clearing grease, scale and roots properly. Jetting costs more but lasts longer for recurring blocks.
Who fixes a choked pipe in my HDB flat?
If the choke is within your flat's own pipes, you hire and pay a contractor. If it's the common discharge stack (often the case when lower floors back up), the town council handles it — report it before paying anyone.
