Renovation Contractor in Punggol

Hold back 10-15% of the contract value for surprises on a standard renovation, and 20% for older properties where opening walls tends to reveal outdated wiring, corroded pipes, or damp. Do not tell the contractor your contingency figure — it is your buffer, not extra scope budget.

A variation is any change to the agreed scope after signing — moving a wall, upgrading tiles, fixing a hidden problem. Insist every variation is priced and approved in writing before the work happens. Most renovation budget blowouts are not the original quote being wrong; they are dozens of verbally-approved variations nobody tracked.

Usually yes for single-room projects if water and power stay connected to the rest of the home; usually no for whole-home work involving dust-heavy demolition or when the only kitchen or bathroom is out of service for weeks. Ask the contractor to phase the works so one bathroom stays functional, and budget for short-term accommodation on gut renovations.

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 Punggol 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.

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.
