Subcontractor Risk: How to Protect Yourself from a Default

The Hidden Risk on Every Project

Subcontractors are essential to construction — but they're also one of the biggest sources of risk. A subcontractor default can delay your project, cost you money, damage your relationship with the client, and — worst of all — affect your bonding capacity.

Most contractors evaluate subcontractors based on price and availability. But price is the least important factor in subcontractor risk. The real question is: will they perform?

The Most Common Subcontractor Risks

• Financial distress: The subcontractor runs out of cash and can't pay their suppliers or workers.
• Labor shortages: The subcontractor doesn't have enough skilled workers to complete the scope on time.
• Overcommitment: The subcontractor takes on too much work and can't service all their projects.
• Poor project management: The subcontractor lacks the systems to track costs, schedule, and quality.
• Sub-subcontractor risk: The subcontractor's subs may default — and you're responsible.

How to Assess Subcontractor Financial Health

• Review their financial statements: Ask for balance sheets, income statements, and cash flow statements. Look for declining margins, growing debt, and thin working capital.
• Check their bonding capacity: If a subcontractor can't get bonded, that's a red flag.
• Ask for references: Talk to other general contractors who have worked with them recently.
• Check their payment history: Ask suppliers if the subcontractor pays on time. Slow payments suggest cash flow problems.
• Monitor their workload: If they're taking on more work than they can handle, they may be overcommitting.

The Cost of a Subcontractor Default

The cost of a subcontractor default is more than just the cost of completing the work. Consider the additional costs:

• Replacement cost: You'll likely pay a premium to bring in a replacement subcontractor on short notice.
• Delay costs: The project is delayed while you find a replacement — and you may have liquidated damages.
• Reputation damage: If the project is delayed, your client may not use you again.
• Bonding impact: A default on your project will be reported to your surety, which can reduce your bonding capacity.

How to Protect Your Project from Subcontractor Risk

• Prequalify subcontractors: Before you award a contract, review their financials, references, and bonding capacity.
• Require bonding: For large subcontracts, require the subcontractor to post a bond. If they can't, that's a warning.
• Include payment provisions: Pay subcontractors based on progress, not upfront. Retainage gives you leverage.
• Monitor performance: Track the subcontractor's progress against schedule and budget. If they're falling behind, address it immediately.
• Maintain a backup list: Have a list of qualified subcontractors ready to step in if your primary subcontractor defaults.

How Subcontractor Risk Affects Your Bonding Capacity

When a surety evaluates your bonding capacity, they look at your subcontractor management. If you have a history of subcontractor defaults — or if you can't show that you assess subcontractor risk — the surety will reduce your capacity.

Sureties also look at your subcontractor payment history. If you don't pay your subcontractors on time, they may file liens — and those liens show up on your project and affect your bonding capacity.

Frequently Asked Questions

Can I require a subcontractor to post a bond?

Yes — for large subcontracts, many general contractors require subcontractor performance bonds. If the subcontractor can't get bonded, that's a red flag.

What should I do if a subcontractor defaults?

First, document everything. Second, notify your surety if the subcontract was bonded. Third, mobilize a replacement subcontractor as quickly as possible.

How often should I review subcontractor financials?

At minimum, before you award a contract. For long-term projects, review financials quarterly.

Does subcontractor risk affect my bonding capacity?

Yes. A history of subcontractor defaults — or lack of subcontractor management processes — will reduce your bonding capacity.
