Construction Contracts & Subcontractor Agreements for Trade Contractors
The Insurance Clauses You Must Understand Before SigninG
Most trade contractors focus on scope, schedule, and payment terms. But the biggest risk in many construction contracts is the risk transfer language. General Contractors and owners often shift liability downstream through indemnity clauses and insurance requirements that may exceed what a standard policy provides. This guide highlights the most important clauses and red flags to help protect your business before you sign.
Indemnity Agreements (Hold Harmless Clauses)
Indemnity clauses can require a subcontractor to pay for claims, damages, and legal defense—even when the subcontractor is not primarily at fault. Watch for broad language such as “regardless of fault,” “any and all claims,” “arising out of or relating to,” or “duty to defend.” Best practice is indemnity limited to the subcontractor’s negligence and comparative fault.
Products/Completed Operations (P/CO): Liability After the Job Is Done
Many lawsuits occur after work is completed (e.g., leaks, fires, moisture issues, or system failures). Contracts may require completed operations coverage to be maintained for 2–10 years. If coverage is cancelled, changed, or excluded later, you may be uninsured and in breach. Completed operations should be reviewed at every renewal and if switching carriers, and you should keep an active log of the furthest future date you need to keep coverage in place, per completed contracts.
Certificates of Insurance (COIs): What They Prove, and What They Don’t
A COI is evidence of insurance, not a contract. It does not change the policy, grant coverage, or override exclusions. “Certificate holder” does not mean “additional insured.” If the contract requires additional insured status, primary/noncontributory wording, or waivers of subrogation, those requirements must be supported by actual policy endorsements—not just certificate wording. Many contractors have blanket AI and Waiver of Subrogation endorsements on their policies, but a contract must be in place for those endorsements to respond. Additionally, specific versions of the Additional Insured endorsement may be required – it’s important that you confirm your policies are in compliance with your contracts.
Pollution Requirements: A Common Source of Uninsured Exposure
Construction contracts increasingly require “pollution” coverage, even for trades. Standard GL policies often exclude pollution-related claims, including certain fumes/vapors, silica dust, mold, sewage, or chemical/adhesive exposure. If your contract requires pollution coverage, you may need a separate Contractor’s Pollution Liability policy. Pointing back to Section 3, if your COI says your GL policy has Pollution coverage, it’s important that you verify that it does - because it's not common.
Professional Liability Requirements: Not Covered by General Liability
Some contracts require professional liability for design-assist, shop drawings, value engineering, or recommendations. General Liability typically covers bodily injury and property damage—not design errors or economic loss. If you provide advice, plans, specifications, or performance guarantees, you may need separate Professional Liability coverage, also referred to as contractor’s E&O.
As a specialized trade contractor, the upstream party’s goal in most contracts is to transfer their risk to you. In most cases, your insurance should respond and protect you if a claim arises. However, many carriers will add exclusions and lengthy endorsements to your policy that narrow your coverage. The Amendment of Insured Contract endorsement is common and can eliminate coverage, depending on the wording of contracts you are entering into.
