Warranty Period
Also called: Defect Liability Period · Warranty Term
A warranty period is the defined window after delivery or completion during which a seller or contractor must fix defects at their own cost, without the buyer needing to prove additional fault. Once it expires, the buyer typically bears the cost of any defects discovered, absent a separate ongoing warranty claim.
In more detail
The warranty period is distinct from — and usually shorter than — any statutory limitation period for bringing a legal claim. It's a contractual commitment to fix things proactively and at no cost, not just a deadline for when a lawsuit must be filed.
What the warranty actually covers matters as much as its length — a warranty limited to "defects in materials and workmanship" is narrower than one covering all defects, and exclusions (misuse, normal wear, third-party modifications) are standard and reasonable within limits.
For construction and complex installation projects, this is often called a "defect liability period" specifically, and may include a retention of final payment until the period concludes without unresolved defects — linking directly to the payment terms.
A contractor completes a construction project with a 12-month defect liability period. A structural crack discovered in month 8 is the contractor's responsibility to fix at no cost; the same defect discovered in month 14 would fall outside the warranty period.
