Finding a reliable plumber in Singapore isn't just a comfort choice — PUB-licensed work is the legal requirement, and insurance claims get rejected when unlicensed work causes damage. A bad plumber can miss a concealed leak that causes ceiling damage to the neighbour below, or install a water heater incorrectly and void a S$400 warranty. KakiList connects you with 184 verified Plumber providers serving the Sembawang area. Our listed providers maintain an average rating of 4.6★ based on Google reviews. Sembawang has a mix of HDB flats and landed properties, with some older colonial-era homes that may require specialized maintenance.

Compare providers, read verified Google reviews, and contact them directly via WhatsApp — no middleman fees or hidden charges.
Sembawang's HDB/Landed mix means plumber providers are usually booked for ageing galvanised iron supply lines, silent cistern leaks, and concealed pipe burst repairs.

Pick a provider from the list above — each card has a direct WhatsApp button. Mention your block number or distance from Sembawang MRT so the provider can quote a realistic arrival time. Same-day bookings are common for Sembawang.
Every licensed plumber in Singapore has a PUB Plumber Licence number. Ask for it upfront — a real licensed plumber will share it without hesitation. You can verify the licence on PUB's licensed plumbers directory. Unlicensed plumbers working on water service lines is an offence under Singapore law, and any damage claim to your home insurance will be rejected.
Basic jobs like tap replacement or unclogging run S\$60-150. Water heater installation S\$150-350 for HDB. Toilet bowl replacement S\$250-500. Emergency and after-hours bookings carry a 30-50% surcharge. Always get the price fixed in writing before the plumber starts work — scope creep after arrival is the top complaint pattern.
Plumbing rates are relatively consistent across Singapore for standard work. HDB/Landed property type affects cost more than location — HDB is most affordable, condo jobs typically 10-20% more due to MCST access rules, landed 20-40% more for multi-storey work. Transport surcharges for remote Sembawang pickups are rare but possible for jobs far from the plumber's base.
Individual negative reviews can be outliers, but patterns matter. If 3+ reviews mention the same issue (pricing surprises, no-shows, rough work), that pattern is likely real. Our rankings weight review quantity as well as score — a plumber with 4.5★ and 200 reviews is more reliably rated than one with 5.0★ and 4 reviews.
For same-day and emergency work, contact 2-3 providers via WhatsApp simultaneously — the first to confirm availability and pricing wins. Emergency response time is typically 1-3 hours for non-water-emergency jobs, 30-60 minutes for burst pipes or major leaks. After-hours rates apply 6pm-8am weekdays and weekends.
