Singapore isn't big, and most contractors will travel anywhere on the island. Still, a firm based near you can pop over for a site visit faster and is often easier to chase when a small fix is needed after handover. This guide lists renovation contractors whose registered address is in the North region, which covers Woodlands, Yishun, Sembawang, Mandai and Sungei Kadut.

We ranked them the same way as all our renovation guides: BCA interior finishing grade (CR06), years since incorporation, other BCA workheads held and how complete the public record is. Being on this list says where a firm is registered, not that it only works there.

How this list was ranked

Each firm gets 0 to 5 points on four things, multiplied by a weight: BCA CR06 (Interior Decoration & Finishing) grade ×4, years since incorporation ×2, other BCA workheads ×2, and how complete its public record is ×1. The total is scaled to 10. We checked 44 firms and show the top 20. Google reviews are shown as not checked until we've checked them for every firm here. Full method

Before you hire

Use the region as a tie-breaker, not the main reason to pick someone. Ask for two or three recent jobs in estates near yours, ask who will supervise on site, and get the payment schedule tied to stages of work rather than dates.

Questions people ask

Do these contractors only work in this region?

No. We grouped them by registered address. Most take jobs island-wide.

Why does a firm appear in more than one guide?

A company can hold several registrations, so it can rank in a trade guide and in its home region's guide. The score is worked out the same way in both.
