Renovation Contractor in Randburg

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.

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 Randburg 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.

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contract value for surprises on a standard renovation, and 20% for older properties where opening walls tends to reveal outdated wiring, corroded pipes, or damp.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 single-room refresh typically takes 1-3 weeks, a kitchen or bathroom 2-6 weeks, and a whole-home renovation 2-6 months depending on structural work and approvals. Add lead time before the start date for permits, custom cabinetry, and contractor availability — good contractors are often booked 1-3 months out.

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.

Manage trades yourself only if the job involves one or two trades and you can be on site regularly. Once a project needs sequencing (demolition, then rough plumbing and wiring, then walls, then finishes), a contractor typically saves more in avoided rework and delays than their 10-20% management margin costs.

Full renovations run roughly R6,500-R12,500 per square metre for standard-to-quality finishes, with cosmetic updates from about R2,500/m². A complete renovation of a standard 3-bed house typically lands between R250,000 and R550,000 (ServiceLink SA, 2025).

Yes — power interruptions stretch timelines for tiling, welding, and anything tool-dependent, and imported fittings swing with the rand. Build schedule buffer into the contract and lock material prices where possible; many contractors add inverter/generator allowances for time-critical trades.
