Does a Performance Bond Cover a Warranty? What Contractors Should Know

Written by Staff Writer | Sep 16, 2026

Your Construction Work Is Complete, But What About Your Performance Bond Obligations?

Imagine you've completed a commercial construction project and moved on to the next job. Months later, the project owner contacts you about a workmanship issue, expecting the performance bond to cover the warranty work. But does your performance bond still apply?

Whether your performance bond applies to post-completion warranty work depends on your contract terms and bond language. That’s why it’s important to understand your project’s requirements before you bid, rather than waiting until an issue arises after completion.

In this article, we explore how performance bonds relate to warranty obligations, when you may need a separate warranty or maintenance bond, and where to find post-completion bond requirements in your project documents.

Why Does Performance Bond Warranty Coverage Vary by Project?

Many contractors aren't sure whether their performance bond still applies to warranty work after a project is complete. This confusion often stems from the number of project documents that may contain warranty requirements and how those requirements relate to the project’s performance bond.

For example, project owners may include warranty language in their contracts, specifications, bid packages, and closeout requirements. As a result, you may need to review multiple documents to understand your post-completion obligations.

What Does a Performance Bond Cover?

A performance bond guarantees your performance of the bonded contract by establishing a legally binding agreement between the following parties:

  • The principal: The contractor responsible for performing the contract
  • The obligee: The project owner who requires the bond
  • The surety: The company that issues you the bond

If you fall short of your contractual performance obligations, your project owner can seek compensation from your surety company, up to your bond amount. After that, you must reimburse your surety for valid claims according to the terms of your indemnity agreement.

Unlike general insurance, a performance bond doesn’t protect you financially; it protects the project owner if you fail to meet specific obligations under your bonded contract. Additionally, the performance bond doesn't provide blanket coverage for project-related problems; its scope depends on the bonded contract and bond form.

Does a Performance Bond Cover Warranty Work?

A performance bond may cover some warranty work, but there isn't a universal yes-or-no answer. Warranty obligations included in your bonded contract can fall within your performance bond's coverage, depending on the bond language and specific circumstances.

Since coverage may extend beyond project completion, you shouldn't assume your performance bond becomes irrelevant once the work is finished. However, some construction projects may establish separate post-completion bond requirements and require you to obtain a warranty bond or maintenance bond for a specified period. For this reason, you should closely review your contract and bond language with a surety specialist.

What Is a Warranty Bond?

A warranty bond guarantees that you’ll fulfill certain warranty obligations for a set period after a project’s completion, such as:

  • Correcting defective workmanship
  • Replacing defective materials
  • Fulfilling other warranty requirements specified in the contract

The required coverage amount, duration, and scope can vary significantly from one project to the next. To avoid surprises, clarify whether you need a separate warranty bond before bidding so you can account for the obligation in your project planning and pricing.

What Is a Maintenance Bond?

A maintenance bond is another term for a warranty bond. These bonds are often required for public, municipal, utility, infrastructure, or sitework projects.

How to Determine Your Warranty or Maintenance Bond Requirements

Identifying your warranty and maintenance bond requirements in advance is important, but locating them isn’t always straightforward. After all, these requirements can appear in several different parts of your bid package.

To avoid missing key requirements, make sure you review your full bid package, including its:

  • Instructions to bidders
  • Bond forms
  • General conditions
  • Supplemental conditions
  • Technical specifications
  • Warranty sections
  • Maintenance requirements
  • Closeout requirements
  • Owner-specific forms
  • Project addenda

Why Should You Review Your Post-Completion Bond Requirements Before You Bid?

Warranty and maintenance bond requirements can affect your project costs, so it’s important to understand them before finalizing your bid. Longer post-completion obligations may also require additional documentation and impact the underwriting process.

By reviewing your bond requirements early, you’ll have more time to:

  • Account for additional bond costs in your pricing
  • Discuss post-completion obligations with your surety professional
  • Gather the necessary information for underwriting
  • Address unusual bond forms or requirements before bid day

7 Common Warranty / Maintenance Bond Mistakes to Avoid

As you examine your warranty and maintenance bonding requirements, avoid making these common mistakes:

  1. Assuming your performance bond covers every warranty issue: Coverage depends on the bonded contract, bond form, and circumstances.
  2. Assuming the performance bond ends immediately after completion: Finishing the work doesn't necessarily end all of your obligations under the bonded contract.
  3. Missing a separate warranty or maintenance bond requirement: Rather than looking at the primary bond section alone, review the entire bid package to identify any additional bonding requirements.
  4. Waiting until project closeout to request a required bond: Identify your requirements early so you have sufficient time to complete the underwriting process and secure the right bond.
  5. Leaving post-completion bond costs out of your bid: Factor any required warranty or maintenance bond into your pricing before you submit your bid.
  6. Overlooking owner-specific bond forms: Some project owners may require their own forms or impose project-specific terms.
  7. Failing to ask questions about unclear requirements: If the contract or bond language isn't clear, raise the issue with the project owner before bidding.
