Sengkang homes are mostly HDB flats built since the early 2000s, and many sit in newer BTO blocks where owners have just collected keys and are deciding on renovation and aircon.
That shapes the work: new-flat aircon installation, renovation follow-ups, waterproofing for bathroom seepage, then regular servicing as systems age. Pest jobs run all year, with more calls after rain and near drains and food outlets around the town centre.
The regulators sit in the background: NEA for pest control and public health, BCA for building work and PUB for water and plumbing, each as relevant to your trade. Customers rarely ask about a licence until they are comparing two quotes, and then it decides.
Buyers price in S$ and expect a quote that says whether GST at 9% is included.
