Home Renovation Contractors in Johannesburg

Home renovation in Johannesburg costs between R5,000 and R25,000 per square metre in 2026, depending on scope. Cosmetic refreshes (paint, flooring, light fittings, hardware) run R5,000–R8,000/m². Mid-range renovations involving kitchen and bathroom upgrades, replastering and rewiring run R12,000–R18,000/m². Full strip-and-rebuild luxury renovations with imported finishes, structural changes, underfloor heating and bespoke joinery run R18,000–R25,000+/m². A typical mid-range renovation of a 146 m² home totals R1.75M–R2.6M. Kitchen renovations range from R80,000 to R500,000 and bathroom renovations from R45,000 to R250,000 depending on size and finishes. Sinqobile Construction provides free, itemised, fixed-price quotes — no hidden fees or surprise extras.

Typical Sinqobile Construction renovation durations in Gauteng: kitchen renovations 4–8 weeks (cabinetry lead time is usually the critical path), bathroom renovations 3–6 weeks (waterproofing cure time plus tiling), open-plan conversions with structural wall removal 4–8 weeks including engineer sign-off, and full home strip-and-rebuild renovations 4–8 months end-to-end. These timelines assume any required council-approved plans are already in place — the City of Johannesburg plans-approval process typically adds 4–12 weeks on top. You will receive a detailed Gantt schedule with your quote and weekly photo progress updates throughout the project.

You need council-approved plans for any structural changes under SANS 10400 — removing or moving load-bearing walls, adding rooms, second-storey additions, changing the roofline, increasing the building footprint, or altering plumbing drainage layouts. Purely cosmetic renovations (new paint, tiles, cabinetry, fixtures, flooring, light fittings) do not require council plans. NHBRC enrolment is only required for additions or extensions that create new habitable floor area — not for like-for-like internal renovations. Sinqobile Construction engages SACAP-registered architects, handles full plans submission to the City of Johannesburg / Tshwane / Ekurhuleni, and enrols qualifying additions with the NHBRC, all included in the fixed-price renovation quote.

A typical mid-range renovation budget in Johannesburg breaks down approximately as follows: structural work and demolition 25–30%, plumbing and electrical first-fix 18–22%, finishes (tiling, plastering, painting) 22–26%, fittings and fixtures (cabinetry, sanitaryware, lighting, ironmongery) 14–18%, and contingency 8–10%. Bathroom and kitchen renovations skew higher on plumbing, electrical and fittings (combined 40–50% of budget) due to waterproofing, geyser work, extractor wiring and built-in joinery. Sinqobile Construction itemises every line in the fixed-price quote so you see exactly where the budget goes before signing.

Yes, in most cases you can stay in your home during renovation. We phase the work room by room and protect living areas with dust barriers, floor coverings and negative-pressure extraction where needed. For full-house renovations involving structural work, full rewiring or whole-house replumbing, we recommend relocating for 2–4 weeks during the most disruptive phase. We will advise on the best approach during your free consultation and can sequence kitchen and bathroom phases to keep at least one functional cooking and washing area available throughout the build.

Renovation costs in Sandton are typically 10–15% higher than other Gauteng areas for three reasons: higher property values justify premium finishes (imported Italian tiles, engineered-stone countertops, designer fixtures, German appliances), larger homes require more materials and labour, and skilled specialist contractors in the area charge higher rates due to demand. Sinqobile Construction's Fourways base gives competitive access to Sandton projects without the premium markup of exclusive Sandton-only contractors — the same NHBRC-registered project management, single fixed-price contract and 5-year workmanship cover, delivered at Fourways pricing.
