During what period does the contractor remain liable for work done under warranty?

The contractor remains liable for work done under warranty during the entire warranty period. This means that the contractor is responsible for addressing any issues or defects that arise within the time frame specified in the warranty agreement. A warranty is a promise or guarantee that a contractor provides to the homeowner that the work will be performed to a certain standard and any issues that occur within the warranty period will be rectified at no extra cost to the homeowner.

This approach is beneficial for homeowners, as it provides them with assurance and protection regarding the quality and durability of the work completed. Since warranties can vary in length depending on the type of work and the terms set forth in the contract, the obligation on the contractor's part to uphold the warranty holds throughout the entirety of that designated period.

The other options suggest limitations on the contractor's liability, but in reality, the entirety of the warranty period is the time during which the contractor must fulfill their obligation to repair or correct any defects that occur.
