Subcontractor Default Insurance is a policy purchased by a general contractor to protect against financial losses when a subcontractor defaults. The insured party is typically the general contractor, not the project owner or the subcontractor. The policy is designed to respond when an enrolled subcontractor fails to meet its contractual obligations.
A default may involve abandonment of work, insolvency, labor shortages, repeated delays, defective work, quality failures, or other breaches that create measurable loss for the contractor. Once a covered default occurs, SDI may reimburse direct costs such as completing the subcontractor’s work, hiring a replacement subcontractor, correcting defective work, or accelerating the schedule.
Policies may also cover certain indirect costs, including increased overhead, liquidated damages, owner delay damages, legal costs, impact investigations, permit fees, designer fees, and costs tied to accelerating other trades. Exact coverage depends on the policy language and carrier terms.
In practical terms, SDI is a tool for subcontractor risk management. It does not eliminate risk. It changes how the general contractor funds, manages, and documents that risk when a subcontractor problem threatens the project.
The core difference is control.
A surety bond is a three-party arrangement involving the subcontractor, the general contractor, and the surety. If there is a default, the surety generally investigates before deciding how to respond. That process can take time, especially when responsibility, damages, or completion costs are disputed.
SDI is a two-party insurance agreement between the general contractor and the insurer. The general contractor usually has more control over which subcontractors are enrolled, when a default is declared, and how quickly it moves to complete the work. This can reduce delays because the contractor does not have to wait for the same kind of surety investigation before taking action.
The tradeoff is risk retention. SDI often has lower upfront pricing than subcontractor bonding, but deductibles can be significant. Deductibles may start around $250,000 and increase from there, with co-pays often ranging from 10% to 20%.
A performance bond may still be required in many settings, especially where the owner or lender wants direct protection. SDI is usually more about protecting the general contractor’s balance sheet and project continuity.
SDI is generally built for larger general contractors with meaningful annual construction revenue and a consistent volume of subcontracted work. Carriers usually want to see enough revenue, project history, subcontractor spend, and internal controls to justify the policy structure.
There is no single universal cutoff, but SDI is usually more realistic for contractors with substantial annual revenues, repeat project volume, and multiple subcontractors across active jobs. Smaller contractors may struggle to qualify because the deductible alone can be too large relative to project size.
Typical pricing may range from about 0.35% or 0.40% up to around 1.5% of covered subcontract values, depending on the contractor, subcontractor pool, project type, prior losses, and market conditions. Policy terms may run two or three years.
Construction Key Factors include project size, subcontractor concentration, labor availability, supply chain exposure, claim history, financial strength, and how well the contractor monitors subcontractor performance during the job.
Carrying SDI makes subcontractor vetting more formal, more documented, and more continuous. The carrier is relying on the general contractor’s prequalification process, so the contractor must show that it is not simply choosing subcontractors based on price or relationships.
Before coverage applies, carriers typically expect a documented prequalification process. That may include financial statements, work-in-progress schedules, backlog reports, safety records, litigation history, bonding capacity, insurance certificates, prior default history, labor availability, key project experience, references, and evidence of business continuity planning.
Contractors may also need to evaluate cash flow, liquidity, overhead, supply chain exposure, availability of skilled labor, and whether the subcontractor has access to alternative suppliers. Post-COVID, this became even more important because delays, shutdowns, labor shortages, and material disruptions made subcontractor failure more likely.
SDI insurance construction programs may also require ongoing monitoring after the subcontractor is approved. That means watching performance, payment issues, manpower levels, schedule slippage, change order disputes, claims, and signs of financial distress. Approval at the start of the project is not enough.
Some contractors may hear SDI referred to as subguard insurance, especially because earlier market use was closely associated with that terminology. Regardless of the label, the central discipline is the same: the contractor must prove it has a serious process for identifying risk before the project is in trouble.
For broader project planning, SDI should sit alongside contract review, cash flow management, retainage strategy, change order procedures, force majeure notice requirements, and tax compliance considerations such as Sales Tax Rules for construction materials and project-related purchases.
No. SDI generally protects the general contractor against losses caused by subcontractor default. If the general contractor defaults, SDI typically does not protect the owner. Owners usually look to contract remedies, parent guarantees, letters of credit, or bonds for that risk.
The contractor usually chooses the subcontractors, but the carrier expects a documented prequalification process. If a subcontractor does not meet underwriting standards or is not properly enrolled, coverage may be limited, excluded, or challenged when a default claim is submitted.
SDI generally is not accepted as a replacement for required bonds on publicly funded projects. Public projects often require statutory bond protection, including payment and performance bonds. Contractors should review procurement rules before assuming SDI can satisfy public project requirements.
If the claim is denied, the general contractor may still have to fund completion, replacement labor, delay costs, and dispute expenses. The project continues under the contract, but the contractor bears the financial burden unless another recovery source is available.
