Senja Plumbing General Contractor is a plumber on Bangkit Road in Bukit Panjang, holding a 5.0 Google rating from its first review. Plumbing in Singapore has one rule worth knowing before anyone picks up the phone: work on the pipes connecting your flat to the public water mains must be done by a PUB-licensed plumber, so it is fair to ask for that licence up front. Regulars also learn to get the scope in writing — whether parts, labour and any follow-up visits are included — before work starts. A blocked floor trap can sometimes be a plunger job, but concealed leaks, which often show up first as damp patches or stains on a neighbour's ceiling, need proper detection rather than guesswork. For homes around Block 274 Bangkit Road and the wider Bukit Panjang estate, having a plumbing firm close by makes a sudden leak that bit less stressful.
