Renovation Contractor in Hougang New Town

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.

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contract value for surprises on a standard renovation, and 20% for older properties where opening walls tends to reveal outdated wiring, corroded pipes, or damp.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.

For most markets 10% or less of the contract value is a reasonable deposit, sometimes up to 20-30% for jobs with heavy upfront material orders like custom cabinetry. Several countries cap deposits by law. Never pay a large share of the total before work starts, and never pay the full amount up front.

A renovation contractor (general contractor or main builder) manages your whole project: pricing the job, scheduling and supervising trades like electricians and plumbers, ordering materials, arranging permits where needed, and being the single party responsible for quality and timeline. You pay one contract price instead of coordinating five separate trades yourself.

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.

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.

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.
