To get bonded for construction, you buy a surety bond through a specialized agent who submits your financials to an underwriter, has you sign a personal indemnity agreement, and issues the bond once you pay a premium. For an established contractor with clean credit, that premium runs 1% to 3% of the contract value. Newer contractors and those with credit problems pay more. The whole process takes anywhere from a few days to several weeks, driven mostly by bond size and how organized your financial documents are.
What “Getting Bonded” Actually Means
A surety bond is a three-party financial guarantee. You (the contractor) promise the project owner you’ll perform. The surety company backs that promise with its own money. If you default, the surety pays the owner and then comes after you to be made whole.
Three bond types cover almost everything a contractor encounters on a job:
- A bid bond guarantees that if you win the bid, you’ll actually sign the contract and provide the required project bonds.
- A performance bond guarantees you’ll finish the work according to the contract.
- A payment bond guarantees you’ll pay your subcontractors, laborers, and suppliers, protecting the owner from mechanic’s liens.
When people talk about “getting bonded” for a specific job, they usually mean performance and payment bonds.
When You’re Required to Have a Bond
Federal law requires performance and payment bonds on any federal construction contract over $100,000. Every state has its own “Little Miller Act” imposing similar requirements on state and local public work, though the dollar thresholds vary. Private owners can require bonds too, but they aren’t obligated to.
Separate from any of this, many states require contractors to carry a license bond just to operate legally. That’s a different product from the project bonds above. License bond amounts commonly range from $2,500 to $100,000 depending on the state and license type, with annual premiums of 1.5% to 7.5% of the bond amount, largely driven by your credit score. You may need the license bond before you can bid at all, and then separate contract bonds for each job you win.
Documents to Gather Before You Apply
Underwriters want evidence that you have the financial strength and track record to finish the job. Pull the following together before you approach an agent:
- Personal and business credit reports. Poor credit won’t automatically disqualify you, but it will raise your premium.
- Financial statements: balance sheet, income statement, and cash flow statement. For larger bonds, sureties typically want CPA-prepared (audited or reviewed) financials rather than in-house numbers.
- A work-in-progress schedule showing every active project, its contract value, percent complete, and remaining costs.
- Certificates showing active general liability and workers’ compensation coverage.
- A completed-project history covering the type, size, and complexity of jobs you’ve delivered.
- Details on the specific project you’re bonding: contract price, location, timeline, and scope.
Scale matters. A $50,000 bond on a small municipal job won’t trigger the same scrutiny as a $5 million performance bond on a highway interchange. For closely held companies, expect the underwriter to ask for personal financial statements from every owner.
Find a Surety Bond Agent
You don’t buy surety bonds directly from the surety company. You go through a producer, or agent, who acts as the intermediary and matches your profile with the right carrier. The National Association of Surety Bond Producers maintains a directory of specialized professionals. A general insurance agent can technically write bonds, but surety underwriting has its own standards and market dynamics; a specialist navigates them more effectively.
Your agent will supply the official bond forms. Federal work uses standardized forms. Whichever form applies, the surety needs 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. Errors here can create coverage disputes later, so read the form carefully before it’s submitted.
How Underwriters Decide
Underwriters look at what the industry calls the three C’s: character, capacity, and capital. Character means reputation, payment history, and completion record. Capacity means whether your company has the equipment, workforce, and management to actually run the project. Capital gets the most scrutiny.
On the financial side, underwriters focus on your current ratio (current assets over current liabilities), your debt-to-equity ratio, profitability trends over recent years, and cash flow health. Working capital relative to your existing backlog is where most decisions get made. A contractor with strong working capital and manageable debt gets bonded quickly and cheaply. A contractor who’s overleveraged or losing money on current work will hit resistance no matter how impressive the project list.
Approval doesn’t come as a yes or no on a single bond. It comes as a bonding capacity expressed as two figures: a single-job limit (the largest individual project the surety will bond) and an aggregate limit (the total bonded backlog you can carry at once). A contractor with a $5 million single and $25 million aggregate can expect quick approval on anything under $5 million as long as total bonded work stays below $25 million. Jobs that push past either number require additional review. As your company grows and your balance sheet strengthens, these limits go up.
Sign the Indemnity Agreement
Before the surety issues anything, you sign a General Indemnity Agreement, or GIA. Read it before you sign it, because this is the document most contractors don’t fully appreciate until a claim hits.
The GIA obligates you to reimburse the surety for every dollar it pays on your bonds, including claim payments, legal fees, and investigation costs. The exposure is personal, not just corporate. Every owner with 10% or more of the company must sign individually, and if you’re married, your spouse will likely need to sign as well. If your company defaults and the surety pays a claim, the surety can pursue your personal assets to recover, even if the business is an LLC or corporation. The agreement is typically notarized and stays in effect as long as you have outstanding bonds with that surety.
This is the structural difference between surety and insurance. With insurance, the insurer absorbs the loss. With a bond, you do.
What the Bond Costs
The premium is calculated as a percentage of the bond’s penal sum or the contract value, and unlike insurance premiums, you don’t get any of it back if no claim is filed.
Established contractors with strong financials and clean credit typically pay 1% to 3%. On a $500,000 project, that’s $5,000 to $15,000. New contractors, contractors with limited history, and anyone with credit issues can expect 3% or higher. Payment is usually due in full before the surety releases the bond documents.
Build the premium into your bid. On public work, project owners expect the bond cost to be inside your bid price. If you’re working on tight margins and haven’t accounted for it, you’re eating 1% to 3% of the contract off the top.
If You Can’t Qualify on Your Own
Small and emerging contractors who can’t get bonded through standard channels have another option. The U.S. Small Business Administration runs a Surety Bond Guarantee Program that guarantees a portion of the surety’s loss if the contractor defaults, which lowers the surety’s risk enough to approve borderline applicants. 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.

Keeping Your Bonding Capacity Over Time
Getting bonded isn’t a one-time event. Sureties review your financials annually, and capacity can shrink as easily as it grows. Each year you’ll submit updated statements, a current work-in-progress schedule, and anything else the surety requests. Deteriorating financials, a run of problem jobs, or late payments to subs will all erode the relationship.
The contractors with the strongest bonding programs treat the surety relationship as core business strategy: clean books, projects finished on time and on budget, adequate working capital, and proactive communication when a job starts going sideways. A surety that trusts you will stretch when you need a larger bond. One that’s been surprised by bad news won’t.
