What Are Surety Bonds

So, What is a Surety Bond Anyway?

Surety Bonds – An Overview 

A surety bond is a financial guarantee that brings three parties together in a mutual, legally binding contract. Corporate surety dates back to the 1800s, but became more common with the creation of the Miller Act of 1935. This federal law required performance and payment bonds for public construction in an effort to protect tax dollars in the case of contractor default. 

So, where do you and your contracting business fit into all of this?

By means of a bond, the surety guarantees that the principal (that’s you) will perform an underlying obligation as promised to a third party, the obligee (the project owner). 

Surety is similar to insurance in that a bond is an assumption of risk in exchange for a payment and it protects against loss. However, unlike insurance, bonds do not protect the product purchaser. They protect your project owner, the obligee. 

Also, full repayment (not a deductible) is paid by the principal in the event of a loss. The surety basically says if any claims occur, you’re good for it. 

Surety bonds guarantee many obligations, such as codes, ordinances, licensing requirements, statues, court orders, and contracts. Bonds are a required prequalification credit for principals and provide protection to third parties.

It's all the same, right? Wrong!

Similarities and Differences of Insurance and Surety Bonds

If you’re not familiar with surety bonds, don’t sweat it — we’ve got you covered on the basics and key differences between insurance and surety. 


Corporate surety is closely related to insurance, and has a longstanding history of protecting businesses. Some similarities between insurance and surety bonds include: 

  • Risk evaluation, followed by a company taking over a risk.  
  • Protection against financial loss in exchange for the receipt of premium.
  • A contract defining the risk.  


Although there are similarities between these two protections, and they often house under the same insurance company, there are significant differences between surety and insurance. 

One major difference to take note of is how losses are handled and who is protected. With insurance, losses are caused by accidental occurrences (e.g. accidental damage to a site, or malfunction). If coverage applies, the insured pays their deductible and the carrier makes them whole again. Traditional insurance seeks to remove or lessen loss exposures. 

Bond losses, on the other hand, are caused by the failure of one entity to perform contractual obligations that they committed to, not accidental events. Sureties do not protect the buyer of a bond (the principal). Bonds protect the third party (the obligee). 

In the event of a loss, the principal (you, the contractor) is expected to completely reimburse the surety. Consequently, the contractor is not protected against financial loss. The risk of default remains with you, the principal. 

Surety losses can be substantial. Hence, accounts are highly scrutinized and underwritten. Underwriting is a constant and ongoing process.

In short, bonds and insurance have differences. However, they both carry the Westfield promise and mitigate risks to benefit others.

Say what? There's more than one type of surety bond?

Surety Is a Tool That Facilitates Commerce

Types of Surety Bonds 

There are two main categories of surety bonds: Contract and Commercial. As we’ve mentioned before, surety bonds are essentially a promise made by a surety to pay the obligee a set amount of money if the principal fails to fulfill the job they were contracted for.

Contract Surety Bonds

Contract surety bonds are largely used for the guaranteeing of construction contracts. There are three parties involved with a contract bond: the project owner, a contractor and a surety. The surety guarantees the project owner that the contractor will fulfill their obligations as outlined within the written contract. 

Below is a breakdown of the different types of contract bonds: 

Bond Type What It Guarantees
Bid Bond If a principal bidding on a project is the lowest bidder, it will enter into the contract and post a performance and payment bond. 
Performance Bond  The contract will be performed according to plans and specifications, within the allotted time frame, at the agreed upon price. 
Payment Bond  Bills for labor and materials associated with the contract will be paid. 
Maintenance Bond  Work will be free of defects for the agreed maintenance period. 

Commercial Surety Bonds

Commercial surety bonds involve all situations outside of a contract bond in which a guarantee is needed. Guarantees are all extremely unique. It is essential that both parties involved understand precisely what the bond is guaranteeing, and the responsibilities of you, the principal. 

There are also countless types of commercial surety bonds. Those specific to your needs as a contractor include: 

Bond Type  What It Guarantees
Supply A guarantee that the supplier will provide all the contractually obligated supplies and materials.
License and Permit   A municipality or other public body may require as a condition to engage in a specified activity, and guarantees that the party seeking the license or permit (the obligor) will comply with applicable laws or regulations.

What's In It For Me?

The Value of Surety Bonds 

How does surety benefit each party, specifically? In other words, what do you, the contractor, get out of it?

Below, we’ve rounded up the top benefits that surety provides each participating party.

Party Benefit
Principal Grants them access to additional bonded work, and thus revenue/profit, while also eliminating unqualified competition.  
Surety Adds an additional product line to the portfolio, which is often profitable. 
Obligee  Prequalifies bidding parties and ensures payment/completion of contractual obligations.
Citizens Protects tax dollars and ensures proper completion of projects.

Bonds are extremely important to ensure faithful performance and payment of contracts. Without bonds, there would be losses to taxpayers due to the misuses of public funds. Owners would be left with unfinished projects and no means to complete them. The bond underwriting process ensures only qualified and responsible bidders perform public work. 

The surety company serves as a valued partner providing advice and solutions to help principals grow and prosper.
