Start with registration. A legitimate contractor operating in KZN should hold a CIDB registration appropriate to the scale of your project. For residential renovations and general building work, look for a Grade 2GB or higher. For civil works such as drainage, earthworks, or site preparation, a 2CE registration is the relevant credential. These registrations are verifiable on the CIDB website using the contractor's CRS number. If a contractor cannot provide their CRS number, that is a clear warning sign.
Ask for a fixed-price quote, not a rate card. A detailed, itemised quote protects both parties. It gives you a clear picture of what is included, what is excluded, and what will trigger a variation. Contractors who only quote per square metre or per day without a defined scope are leaving you exposed to cost overruns. A professional contractor will walk the job, ask questions, and come back with a written scope before pricing.
Check references and look at completed work. Ask the contractor for two or three completed projects you can contact directly. A short phone call with a previous client will tell you more than any marketing material. In KZN, where the renovation market is active across Durban, Pietermaritzburg, and the surrounding areas, a contractor with a solid track record will have no hesitation providing references.
