Featured work — not a six-card template
Two jobs that dominate WhatsApp on any given week, told as editorial splits with real crew photos.
Choked drains
Floor traps and kitchen stacks that will not clear themselves
Hair, grease, and foreign objects choke HDB and condo traps every week. We diagnose trap type from your photos, bring the right rods and jetting kit, and water-test before we leave.
From $60 choke clearing · survey from $50 if concealed
Wet-area plumbing
Mixers, cisterns and heater-point plumbing that drip or run
Dripping shower mixers, running cisterns and heater-adjacent pipework are day-to-day call-outs. Photo the fitting; we quote labour plus parts before we start. Full heater replacements also via aot-heater.com.

Slow kitchen trap that kept coming back
- Problem Homeowner sent a photo of a slow kitchen floor trap and postcode. Grease and debris suspected after repeated DIY plunging.

08 · FAQ
Straight answers
How much does a plumber cost in Singapore?
AOT starts with a site survey from $50. Common works: tap and shower mixer from $50 plus parts, choke clearing from $60, pipe leak repair from $80. Larger or concealed work is quoted after we see the site — price confirmed before we start.
What does the $50 site survey cover?
Attending your unit, inspecting the fitting, drain or pipe run, and giving you a clear scope and price before work begins.
Are your plumbers PUB licensed?
Yes. Licensed plumber Lam Kien Choon, licence WS16882018 — verify on PUB's website.
Do you provide 24-hour emergency plumbing?
No. Hours are Mon–Sat 08:00–17:00. Same-day call-outs where the crew is slotted; after-hours only if someone is available.
Can I get a quote on WhatsApp without a site visit?
For straightforward items — dripping mixer, running cistern, choke, tap replacement — photos usually suffice for a from-price. Concealed work is confirmed on site first.
