Renovation Contractor in Serangoon

Document defects in writing with photos, give the contractor a written chance to fix them within a set period, and withhold only the retention amount — not all payment — while they do. If they abandon the job, your remedies are your contract, any licensing body's complaint process, consumer protection agencies, and small claims court. This is why the paper trail and staged payments matter from day one.

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.

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 every contractor to break the quote into the same line items: demolition, structural, plumbing, electrical, walls and finishes, fixtures, and a stated allowance for materials you choose. Then compare line by line. A single lump-sum number cannot be compared and cannot be enforced when scope questions come up mid-project.

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.
