Construction Defects and Warranty Periods: Know Your Rights and Liabilities After Project Completion

The Supreme Court's 2006 ruling in William Golangco Construction Corporation v. Philippine Commercial International Bank (G.R. No. 142830) clarifies a critical question in Philippine construction law: when does a contractor's liability for defective work actually end? The answer matters to both property owners and contractors, because it draws the line between a contractor's contractual warranty and the owner's statutory rights under the Civil Code.

The Facts: A Peeling Facade

William Golangco Construction Corporation (WGCC) built the extension of PCIB Tower II for the Philippine Commercial International Bank (PCIB). The project included a granitite wash-out finish on the building's exterior walls. PCIB accepted the completed work in June 1992, and WGCC posted a one-year guarantee bond as required by the contract.

In 1993, portions of the exterior finish began peeling and falling off the walls. WGCC made minor repairs. But in 1994, PCIB hired another contractor to redo the entire finish, spending P11,665,000. PCIB then sought reimbursement through arbitration at the Construction Industry Arbitration Commission (CIAC), which held WGCC liable. The Court of Appeals affirmed. WGCC appealed to the Supreme Court.

The Issue: What Does a One-Year Warranty Cover?

The central question was whether WGCC remained liable for defects that appeared after the one-year defects liability period stated in Article XI of the construction contract. That article guaranteed the work and required the contractor to "make good any defect in materials and workmanship which becomes evident within one (1) year after the final acceptance of the work."

PCIB argued that the defects were hidden or latent, and that other contract provisions kept WGCC's obligations alive. The Supreme Court disagreed and ruled in favor of WGCC.

The Ruling: Contracts Are the Law Between the Parties

The Court anchored its decision on Article 1306 of the Civil Code, which upholds the autonomy of contracts. The parties may agree on any terms they deem convenient, provided these are not contrary to law, morals, good customs, public order, or public policy. Obligations arising from contracts have the force of law between the parties and must be complied with in good faith (Article 1159).

The one-year defects liability period was a valid, freely negotiated term. The Court noted that such limitations are not only fair but necessary—without them, a contractor would face a perpetual guarantee on all materials and workmanship. A one-year guarantee is established usage in Philippine construction contracts, both private and government.

No Hidden Defects Here

The Court also rejected PCIB's claim that the peeling finish was a hidden or latent defect. Under Article 1719 of the Civil Code, acceptance of work relieves the contractor of liability for defects unless the defect is hidden and the employer could not reasonably be expected to recognize it, or the employer expressly reserved its rights.

The Court found no hidden defects because PCIB's own team of experts supervised the work, received regular progress reports and photographs, had site access, issued punch lists for compliance, supplied the materials for the finish, and concurred in the turnover. The defects liability period existed precisely to give PCIB a limited opportunity to demand corrections within one year—an opportunity it did not timely exercise for the full extent of the damage.

Practical Takeaways

• Read your warranty clause carefully. A one-year defects liability period is standard and enforceable. After it lapses, the contractor generally cannot be held liable for defects, unless they are truly hidden or rights were expressly reserved.
• Owners should act within the warranty period. Inspect the work thoroughly before and after acceptance. Document defects and demand correction within the agreed period—waiting too long can forfeit your claim.
• Contractors gain certainty from clear warranty terms. A well-drafted defects liability clause protects against indefinite exposure, but it must be honored in good faith.
• Supervision matters. An owner who actively supervises work, supplies materials, and accepts the project with expert concurrence weakens any later claim of hidden defects.
• Contract terms prevail over general expectations. Courts will not rescue a party from an unfavorable contract freely entered into, so negotiate warranty periods and scope before signing.
