What is a maintenance bond and when is it required?

Maintenance bonds are sometimes required as a condition of final payment on public projects. They guarantee that if defects in your work are discovered after project completion, you’ll remedy them during the warranty period.

Bond amount: typically 10–25% of the original contract value. Duration: 1–2 years after substantial completion is most common.

Maintenance bonds differ from performance bonds (which cover completion) in that they cover post-completion defects. They’re less common than performance/payment bonds but do appear on public projects and some private commercial work.
