Renovation Contractor in Wong Tai Sin District

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value for surprises on a standard renovation, and 20% for older properties where opening walls tends to reveal outdated wiring, corroded pipes, or damp.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

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.

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.

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.

Budget renovations run roughly HK$300-500 per square foot, mid-range HK$600-1,000, and designer/luxury work HK$1,200+. A typical 400-500 sq ft flat therefore lands around HK$250,000-400,000 for a full mid-range renovation.

Almost every building requires you to notify management, pay a refundable renovation deposit, and keep noisy works within permitted weekday hours. Separately, structural alterations and drainage works fall under the Buildings Department's minor works regime and need registered contractors — your contractor should identify which items on your scope are controlled.
