Renovation Contractor in Tampines Estate

At minimum: full scope of works, itemized price, start and completion dates, payment schedule tied to milestones, who obtains permits, how variations are priced and approved in writing, warranty terms, and how disputes are handled. If a contractor resists putting these in writing, that is the answer to whether you should hire them.

Ask: who will actually be on site daily (the owner or a foreman), which parts are done by their own team versus subcontractors, how many projects they run at once, what their current lead time in Tampines Estate is, how they price variations, and what their warranty covers and for how long. The quality of the answers tells you as much as the answers themselves.

Payments should follow completed milestones, not calendar dates: for example deposit, completion of demolition and first-fix (rough-in), completion of second-fix and finishes, then a final payment of 5-10% held until the snag list (punch list) is closed. That final retention is your only real leverage for defect fixes.

One combined project is almost always cheaper per unit of work: a single mobilization, one round of demolition and dust protection, and better contractor pricing on a larger contract. Stage the work only if cash flow requires it, and sequence it so you never redo finished work — for example, complete all plumbing and electrical changes before any room gets its final finishes.

Cosmetic work (painting, flooring, replacing fixtures in place) rarely needs a permit. Structural changes, wall removals, and significant plumbing or electrical alterations usually do, and rules in Tampines Estate follow your national and local building codes. Ask the contractor to name the specific approval needed and who applies for it — a contractor who suggests skipping permits is transferring the legal risk to you.

Manage trades yourself only if the job involves one or two trades and you can be on site regularly. Once a project needs sequencing (demolition, then rough plumbing and wiring, then walls, then finishes), a contractor typically saves more in avoided rework and delays than their 10-20% management margin costs.

Qanvast's 2025 data puts a 3-room BTO at roughly S$36,000-S$44,000, a 4-room at S$51,000-S$62,000, and a 5-room at S$67,000-S$82,000 for full renovations. Resale flats cost more than BTOs because of hacking and rectification of older finishes.

Typical full renovations run 8-10 weeks for a 3-room flat and 10-12 weeks for a 5-room, plus permit approval time before starting. Noisy-works restrictions (weekdays 9am-5pm only) are a big reason timelines are longer than overseas equivalents.
