Delaware Maintenance Bond

Delaware's public works law, 29 Del. C. § 6962, requires a bid bond of at least 10% of the bid and a performance bond of 100% of the contract price on large public works contracts, but does not require a separate maintenance or warranty bond. When one is used, the contract or local agency sets it.

About this bond

What a maintenance bond is

A maintenance bond, also called a warranty bond, guarantees your finished work is free of defects in materials and workmanship for a set period, often one or two years. Sometimes it's built into the performance bond; sometimes the owner wants it separately.

FAQs

Common questions.

Does Delaware law require maintenance bonds?

Usually the contract or the local agency sets it, not a statewide law. The contract states the amount and how long it lasts.

How long does a maintenance bond last?

As long as the warranty period in the contract, commonly one or two years after the owner accepts the work.

What does it cost?

You pay a premium, not the bond amount. The surety sets the premium after it reviews your application, usually as a percentage of the bond amount. We show you the terms before you commit.
