Geylang has old building stock, and it shows in the work. Shophouse rows carry kitchens, drains and roof leaks. Walk-up flats have older pipes and no lifts to help with equipment. Nearby HDB blocks bring steady servicing demand.
The hotter months in the middle of the year push aircon calls, and the north-east monsoon rains around the turn of the year bring leaks and choked drains. Food outlets along the lorongs keep pest control busy all year.
Licensing depends on the work: PUB for licensed plumbing, NEA for pest control operators and BCA where building works are involved. Buying one big Geylang circle of ads wastes clicks your van cannot reach.
Fees and results are in S$, and GST at 9% applies where relevant.
