Best HDB Renovation Contractors in Singapore (2026)

Our pick: HDBRenovation.sg

Yes, that's us — judged against the criteria below, here's the case: over 15 years renovating HDB flats specifically; direct-contractor pricing with fully itemised quotes; small renovations completed within 30 days; HDB permits, timing rules and waterproofing discipline handled as standard; and recent completed work you can inspect in our project gallery. We'll happily be compared on all five points — that comparison is exactly what this guide equips you to make.

The five criteria that actually separate contractors

1. HDB registration you've verified yourself. Works in HDB flats must be done by a contractor in HDB's Directory of Renovation Contractors. Search the directory on HDB's site — don't accept a logo on a namecard. Established firms like Empire Works, Sky Renovation and Hoong Fatt Heng appear there alongside us; fly-by-night operators don't.
2. Itemised quotations. A line-by-line quote (hacking: $X, kitchen carpentry: $Y per ft, waterproofing: $Z) lets you compare fairly and prevents the classic dispute where 'renovation' turned out not to include something obvious. Lump-sum quotes are a red flag in themselves.
3. A written schedule with milestone payments. Payments should track completed stages — never more than a modest deposit upfront. A contractor asking for 50% before hacking starts is financing other projects with your money.
4. Verifiable recent work. Photos are a start; better is a project from the last six months whose owner you can ask three questions: Did it finish on time? What did defects rectification look like? Would you use them again?
5. Fluent answers on compliance. Ask what needs a permit in your scope, the noisy-works hours, and how waterproofing is tested. Contractors who know these cold run compliant, smooth sites; vague answers predict stop-work orders.

Red flags that should end the conversation

• Pressure to sign on the first visit, or a "today-only" discount.
• Quotes dramatically below everyone else — the gap reappears later as variation orders.
• No physical address, no permit talk, cash-only payment requests.
• Promising Saturday hacking or Sunday works — they're telling you they breach HDB rules as a business model.

Contractor or interior designer?

If you want a developed design concept with 3D renders and styling, an interior design firm earns its 15–30% premium. If you know roughly what you want — most owners with a Pinterest board do — a direct contractor builds the same physical scope for less. We've laid out the full comparison on our HDB renovation contractor page.

Getting comparable quotes

Shortlist two or three contractors, give each the same brief (floor plan, scope list, reference photos), and require itemised quotes. Comparing line items — not totals — reveals who's pricing honestly. We're glad to be one of the quotes; our number is built to survive that comparison.
