Short answer. It depends on why the work was defective. Under Article 1716 of the Civil Code, any agreement waiving or limiting the contractor's liability for defective work is void if the contractor acted fraudulently. A standard no-liability clause cannot shield a contractor who deliberately concealed or caused a defect.

The rule and its limit
Article 1716 draws a clear line: "An agreement waiving or limiting the contractor's liability for any defect in the work is void if the contractor acted fraudulently." The clause in your contract may be perfectly enforceable if the defect resulted from ordinary negligence, a misunderstanding of specifications, or an honest mistake. But once fraud enters the picture — deliberate use of substandard materials, concealment of a known structural problem, falsification of test results — the waiver clause falls away entirely as a matter of law.
What counts as fraud in this context
Fraud in construction contracts is not limited to outright lies. It can include knowingly using materials that do not meet the agreed specifications, deliberately hiding defects during inspection, or certifying work as complete when the contractor knows it will fail. The key is intentional deception — the contractor knew the defect existed or would result from the work and chose not to disclose or correct it. Mere negligence, even serious negligence, is a different standard and does not automatically trigger Article 1716.
What the void clause means for your claim
When the waiver is void, it is treated as if it was never written. You are left with whatever rights the Civil Code gives you against a contractor for defective work, which include demanding that the defect be repaired, seeking a reduction in the contract price, or claiming damages for the harm the defect caused. The voiding of the clause does not automatically entitle you to damages — you still need to establish that the defect exists, that it resulted from fraud, and what loss you suffered as a result.
Practical steps if you suspect fraud
Before pursuing any claim, document the defect thoroughly: photographs, written reports from a licensed engineer or architect, and any communications where the contractor acknowledged a problem or gave assurances that were later shown to be false. The distinction between negligence and fraud can be difficult to prove without evidence of the contractor's state of mind. Independent technical assessment is usually the starting point. Consult a lawyer before making demands, as the framing of your claim — fraud versus negligence — will shape both what you can recover and how the waiver clause is treated.
