Subcontractor Risk: How Your Subs’ Insurance Can Blow Up Your Claim

In construction, risk doesn’t disappear — it moves.

And if you’re a general contractor, that risk can move straight back to you when a subcontractor’s insurance program isn’t built correctly.

If your subcontractor’s insurance doesn’t match your contract, you may end up paying for a claim you thought you transferred.

At Haughn Insurance, located in Dublin, Ohio, we work with general contractors every day who assume their subcontract agreements protect them — until a claim proves otherwise.

Let’s break down where things go wrong and how to fix it before it costs you.

1. Indemnity Clauses and Insurance Requirements Must Work Together

An indemnity clause says the subcontractor agrees to defend and indemnify you.

That’s good — but it’s only paper protection.

Insurance is what funds that promise.

If your subcontract agreement requires indemnification but:

  • The subcontractor doesn’t carry the right insurance,

  • The limits are too low,

  • You are not properly listed as Additional Insured,

  • There’s no Primary & Non-Contributory wording,

  • Or there’s no Waiver of Subrogation,

…then the indemnity clause becomes a collection problem instead of an insurance solution.

The contract transfers responsibility.
The insurance makes it collectible.

You need both — aligned and enforced.

2. Minimum Insurance Standards for Subcontractors

Every GC should have written minimum insurance standards. At a baseline, your subcontractors should carry:

Commercial General Liability (CGL)

  • $1,000,000 per occurrence

  • $2,000,000 aggregate (higher for larger jobs)

  • Ongoing & Completed Operations

  • Additional Insured (CG 20 10 & CG 20 37 or equivalent)

  • Primary & Non-Contributory wording

  • Waiver of Subrogation

Commercial Auto Liability

  • $1,000,000 combined single limit

  • Applies to owned, hired, and non-owned autos

  • AI + Waiver when applicable

Workers’ Compensation

  • Statutory limits

  • Employer’s Liability at least $500,000 (often $1M)

  • Waiver of Subrogation in your favor

Umbrella / Excess Liability

  • Often required depending on project size

  • Must follow form over GL, Auto, and Employer’s Liability

These aren’t just checkboxes. They protect your loss history, your EMR, and your ability to win future work.

3. The Hidden Landmine: No Workers’ Comp or Misclassified Workers

This is where claims get ugly.

If a subcontractor:

  • Has no Workers’ Compensation policy,

  • Misclassifies employees as independent contractors,

  • Or allows coverage to lapse,

And one of their workers gets injured on your jobsite?

The claim can fall back on you.

In many states, including Ohio, a general contractor can be held responsible if a subcontractor fails to secure Workers’ Compensation coverage.

That means:

  • Your Workers’ Comp carrier may step in,

  • Your loss history increases,

  • Your experience mod (EMR) can rise,

  • And your premiums go up for years.

One uninsured sub can cost you far more than the job was worth.

4. Real-World Example: When Coverage Fails

Picture this:

A subcontractor installing windows causes water intrusion. Months later, mold damage is discovered. The property owner sues the GC.

You tender the claim to the subcontractor’s GL carrier.

But:

  • The sub let their policy lapse.

  • The COI you received was 9 months old.

  • You were never properly listed as Additional Insured.

Now your GL policy responds.

The loss hits your record.
Your carrier pays.
Your future premiums increase.
And your loss ratio affects future underwriting decisions.

The claim you thought you transferred… never actually left you.

5. A Simple System for Tracking Subcontractor COIs

Too many contractors rely on a file folder and good intentions.

Here’s a simple system that works:

Step 1: Written Insurance Requirements

Standardize your subcontract agreement language.

Step 2: Certificate Review Checklist

Do not just collect the COI. Verify:

  • Policy numbers

  • Effective and expiration dates

  • Limits

  • Endorsements (AI, Waiver, PNC)

  • Matching named insured

Step 3: Expiration Tracking

Use:

  • A spreadsheet with expiration dates,

  • A CRM system,

  • Or third-party certificate tracking software.

Set reminders 30–45 days before expiration.

No updated COI?
No jobsite access.

Step 4: Audit Endorsements

Request copies of actual endorsements — not just the certificate.

Certificates do not modify coverage. Endorsements do.

6. Why This Matters More Than Ever

Insurance carriers are tightening underwriting.

Large losses involving subcontractors are one of the fastest ways to:

  • Lose preferred carrier access,

  • Face non-renewal,

  • Or see significant rate increases.

Risk transfer is not a paperwork exercise. It’s a profit protection strategy.
