If you work in construction, you've likely heard the term maintenance bond mentioned during contract negotiations.

But what exactly does it cover, who needs one, and how does it differ from other surety bonds? At Lincoln Surety Group, we help contractors secure the right bonds quickly and affordably, and understanding maintenance bonds is the first step toward staying protected and compliant on every project you take on.

What Is a Maintenance Bond?

A maintenance bond is a type of surety bond that guarantees a contractor will correct any defects in materials or workmanship that appear after a construction project is completed. It protects the project owner, often a government agency or private developer, from having to pay out of pocket for repairs caused by substandard work within a defined period after project completion.

In simple terms, a maintenance bond is a financial guarantee that your work will hold up long after the job is finished. If cracks, leaks, structural issues, or other defects arise due to poor workmanship, the bond ensures funds are available to fix the problem without the project owner absorbing the cost themselves.

A bid bond is a type of surety bond that provides assurance to project owners (also called obligees) that contractors submitting bids are doing so in good faith. In simple terms, it separates serious, qualified contractors from those who may not have the financial strength or commitment to follow through.

When a contractor submits a bid backed by a bid bond, they are making two key promises:

1. They will accept the contract if awarded the project, and
2. They will provide the required performance and payment bonds to guarantee the job’s completion and payment of subcontractors and suppliers.

This added layer of protection helps project developers move forward with confidence, knowing they are working with vetted professionals.

Protection Against Risk

Bid bonds play a crucial role in protecting project owners from financial loss. Here’s how:
