Renovation Contractor in Serangoon Garden

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 Serangoon Garden 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.

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.

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.

Check the licence or registration your country requires (see the hiring checklist for your country), ask for proof of liability insurance, and ask for two or three recent customers in or near Serangoon Garden you can actually contact. A legitimate contractor expects these questions; evasiveness on any of the three is a reliable early warning.

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.

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.

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.
