Defective Building Work: Remedies for Homeowners and Employers

Cracks spreading through new plaster, a roof that leaks with the first summer storm, a floor slab that was never level — defective building work turns the most expensive purchase of your life into a source of daily frustration. The good news is that South African law gives the owner of a defective building a well-developed set of remedies: against the contractor in contract, against professionals such as architects and engineers who fell short of their duties, and in some cases through statutory warranty schemes. The bad news is that these remedies are easily weakened by delay, by poor record-keeping, or by well-meaning but premature DIY repairs. This article sets out the remedies and the practical steps that make them stick.

What the Contractor Owes You

Every building contract — whether a signed standard form or a handshake deal — imports the essential obligations of the builder's trade. The contractor must carry out the works in a proper and workmanlike manner, using materials of suitable quality, in accordance with the agreed plans and specifications. The works must also comply with the law, including the National Building Regulations and Building Standards Act 103 of 1977 and the building regulations made under it. For new homes, the statutory warranties under the Housing Consumers Protection Measures Act 95 of 1998 apply in addition, obliging registered home builders to rectify defects notified within the prescribed periods after occupation.

Work that falls short of these standards is defective performance — a breach of contract. Everything that follows flows from that simple characterisation.

Remedies While the Project Is Running

Where defects emerge during construction, the first port of call is the contract itself: most standard-form agreements empower the employer or its agent to instruct the removal and replacement of defective work, and completion certificates are withheld until defects on the snag list are attended to.

The employer's most practical lever, however, is payment. Building contracts are reciprocal: the contractor's right to payment is tied to proper performance. An employer faced with defective work may, in appropriate circumstances, raise the exceptio non adimpleti contractus — the defence that payment is not due because the work has not been properly done. The classic authority is BK Tooling (Edms) Bpk v Scope Precision Engineering (Edms) Bpk 1979 (1) SA 391 (A), where the then Appellate Division confirmed the principle of reciprocity and held that a contractor who has performed defectively but whose work is nonetheless being used by the employer may, in the court's discretion, recover only a reduced contract price — reduced, in effect, by what it will cost to remedy the defects. The employer must be ready to prove that rectification cost.

Where the breach goes to the root of the contract and the contractor will not or cannot put it right, the employer may cancel, complete the works through another contractor, and claim the additional cost as damages. Short of cancellation, the ordinary measure of damages for defective work is the reasonable cost of rectification.

Latent Defects After Completion

Not all defects announce themselves at handover. The law distinguishes patent defects — those discoverable on reasonable inspection — from latent defects, which lie hidden in foundations, waterproofing, wiring or structure and surface only months or years later. Accepting the works and paying the final account does not, in itself, forgive latent defects: a claim for the cost of rectifying them generally survives completion, and standard-form contracts such as the JBCC make specific provision for liability for latent defects after final completion.

Time, however, is the enemy. A contractual claim is a debt, and under the Prescription Act 68 of 1969 it ordinarily prescribes three years after it becomes due. Prescription only begins to run when the creditor has knowledge of the identity of the debtor and of the facts from which the debt arises — which protects the owner of a truly hidden defect — but the Act deems you to have that knowledge if you could have acquired it by exercising reasonable care. An owner who notices tell-tale cracking and waits four years to investigate will likely find the claim dead on arrival. For new homes, remember too that the NHBRC warranty periods (three months, one year for roof leaks, five years for major structural defects) run from occupation and require notice within the period.

Claims Against Architects and Engineers

Sometimes the true cause of a defective building is not the builder's workmanship but the design, or the professional supervision that was supposed to catch the problem. Architects, engineers and other built-environment professionals must perform their services with the skill, care and diligence reasonably expected of their profession. A professional who designs an inadequate foundation, or certifies work that plainly did not comply, may be liable for the loss that results.

The route to that liability matters. In Lillicrap, Wassenaar and Partners v Pilkington Brothers (SA) (Pty) Ltd 1985 (1) SA 475 (A), the then Appellate Division held that where professional services are rendered under a contract, a claim for pure economic loss caused by negligent performance lies in contract, not in delict. The practical consequences: identify who actually appointed the professional (owner or contractor), read the letter of appointment — including any limitation of liability — and frame the claim accordingly. Where there was no contract between the owner and the professional, a claim is more difficult and needs careful legal analysis before money is spent pursuing it.

Practical Steps to Build Your Case

1. Document everything immediately. Photograph and date the defects, keep the contract, drawings, invoices and all correspondence, and record when each problem first appeared.
2. Get an independent expert report. A structural engineer or experienced building inspector should identify each defect, its cause and the remedial work required. In litigation, the expert's opinion — not the owner's frustration — proves that work was defective.
3. Give written notice and an opportunity to rectify. Many contracts (and the NHBRC scheme) require it, and a contractor who ignores a clear, reasonable demand looks far worse in any later proceedings.
4. Quantify the claim properly. Obtain detailed, comparable quotations for rectification. Damages must be proved, not guessed.
5. Do not destroy the evidence. Where possible, allow inspection before major remedial work — or ensure your expert fully records the defects first if repairs cannot wait.
6. Take advice early on forum and time limits. Adjudication or arbitration clauses, NHBRC processes and prescription all shape the strategy — and all reward early action.
