To get bonded for construction, you apply through a surety bond agent who submits your financial records to a surety company’s underwriters, sign a general indemnity agreement once approved, and pay a premium that typically runs 1% to 3% of the contract value for established contractors. The full process can take a few days for a small bond or several weeks for a large one, and the surety’s decision rides mostly on your credit, your financial statements, and your track record of finishing jobs.
Here is what each step looks like in practice, what underwriters are actually looking for, and where contractors most often get tripped up.
What You’re Buying
Construction bonds are not insurance. They are a three-party guarantee: the surety promises the project owner that you will perform, and you promise the surety you will pay back anything it has to spend if you don’t. Most contractors deal with three types.
- A bid bond guarantees that if you win the bid, you will sign the contract and provide the required bonding.
- A performance bond guarantees you will finish the job to the contract’s plans and specifications.
- A payment bond guarantees you will pay your subcontractors, laborers, and suppliers.
Performance and payment bonds are what people usually mean by “getting bonded.” They are required on nearly all federal construction contracts above a set threshold and on most state and local public work. Private owners can require them too.
One boundary worth drawing early: a contractor license bond, which many states require just to operate legally, is a different product with its own application and premium. You may need one of those before you can bid, and you’ll still need separate contract bonds for each job.
Documents to Gather Before You Apply
Underwriters want evidence that you have the money, the people, and the history to finish what you start. Pulling the paperwork together before you contact an agent will save you days.
- Personal and business credit reports. Poor credit won’t automatically disqualify you, but it raises your rate.
- Financial statements: balance sheet, income statement, and cash flow statement. For larger contracts, sureties usually want CPA-prepared (reviewed or audited) statements rather than in-house numbers.
- A work-in-progress schedule listing every active project, its contract value, percent complete, and remaining costs.
- Certificates showing active general liability and workers’ compensation coverage at adequate limits.
- A completed-project history showing the type, size, and complexity of jobs you have delivered.
- Details on the specific project you need bonded: contract price, location, timeline, and scope.
The depth of what gets asked scales with the bond size. A $50,000 bond on a small municipal job won’t trigger the same scrutiny as a multimillion-dollar performance bond on a highway interchange. For closely held companies, expect to produce personal financial statements for every owner, listing liquid assets and personal debts.
Find a Surety Agent, Not a General Insurance Broker
You don’t buy a surety bond directly from the surety. You go through a producer, usually called a surety bond agent, who places your file with the carrier most likely to approve it on the best terms.
A specialist matters here. General insurance agents can technically write bonds, but surety underwriting is its own market with its own standards, and generalists often don’t know which carriers will stretch for which profiles. The National Association of Surety Bond Producers keeps a directory of agents who focus on surety work.
Your agent will provide the official bond forms your project requires. Federal work uses standardized forms. These documents ask for the penal sum (the maximum the surety would pay on a claim), the legal names of all parties, the project location, and the contract date. Get the names and numbers right the first time; errors create coverage fights later.
How Underwriters Decide
Sureties evaluate the “three C’s”: character, capacity, and capital.
Character is your reputation and payment history. Capacity is whether your company has the equipment, workforce, and management to run the project in question. Capital is the financial side, and it gets the hardest look.
On the numbers, underwriters focus on your current ratio (current assets divided by current liabilities), your debt-to-equity ratio, profitability trends over the past few years, and whether cash flow shows the business is actually generating money. Working capital relative to your backlog is where most decisions get made. Strong working capital and manageable debt get you bonded quickly and cheaply. Overleveraged books or bleeding cash on current jobs will hit resistance no matter how good your past projects look.
Approval comes with a bonding capacity: a single-job limit and an aggregate limit. The single-job limit caps the largest individual project the surety will bond. The aggregate limit caps your total bonded backlog. A contractor with, say, a $5 million single and $25 million aggregate can get fast approvals on any bond up to $5 million as long as total bonded work stays under $25 million. Jobs that push past either number need extra review and aren’t guaranteed. Those limits grow as your balance sheet and track record grow.
Sign the Indemnity Agreement with Your Eyes Open
Before the surety issues anything, you sign a General Indemnity Agreement. It commits you to reimburse the surety for any losses it pays on your bonds, including claim payments, legal fees, and investigation costs.
The exposure is personal, not just corporate. Every owner holding 10% or more of the company signs individually, and if you’re married, your spouse usually signs too. The surety does this to keep owners from moving assets into a spouse’s name. The practical result: if your company defaults and the surety pays, it can pursue your personal assets to recover, even if your business is an LLC or corporation.
The GIA is typically notarized and stays in force as long as you have bonds outstanding with that surety. It is a serious financial commitment. Read it before you sign it.
What It Costs
The premium is what you pay the surety to issue the bond, calculated as a percentage of the bond’s penal sum or the contract value. Unlike insurance, you don’t get it back if no claim is ever filed.
Established contractors with clean credit and solid financials usually pay 1% to 3%. On a $500,000 contract, that is $5,000 to $15,000. New contractors, those with thin project histories, and anyone with credit problems should expect 3% or higher. The premium is normally due in full before the surety releases the bond.
Build the premium into your bid. Public owners expect contractors to price bonding into the contract. If you forget, you’re giving back 1% to 3% of the job off the top.
If You Can’t Qualify on Your Own
Small and emerging contractors who can’t get bonded through the standard market have another path. The U.S. Small Business Administration runs a Surety Bond Guarantee Program that backs a portion of the surety’s loss if the contractor defaults. That reduced risk is often enough to get a borderline applicant approved.
The program covers contracts up to $9 million for non-federal work and up to $14 million for federal contracts.1U.S. Small Business Administration.

After the First Bond: Keeping the Program Alive
Getting bonded once isn’t the finish line. Sureties review your financials every year, and your capacity can shrink as easily as it can grow. Each year you’ll submit updated financial statements, a current work-in-progress schedule, and whatever else the underwriter asks for. Weakening financials, troubled projects, or late payments to subs can erode the relationship.
Contractors with the strongest programs treat the surety as a core business relationship. Clean books, projects finished on time and on budget, adequate working capital, and honest early communication when a job goes sideways all compound. A surety that trusts you will stretch for the bond you need. One that has been surprised by bad news won’t.
