# Chubb vs Marsh Builders Risk Insurance

Chubb underwrites named builders-risk programs; Marsh McLennan Agency places the line inside a broader property practice.

## Research Scope and Use

Use this comparison to evaluate Chubb and Marsh for Builders Risk Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Chubb writes individual-project and master builders-risk policies, including delay-in-opening. Marsh McLennan Agency treats builders' risk as a property-practice placement covering buildings under construction, not a separately branded product.

## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

## What Is Builders Risk Insurance?

Builders risk insurance addresses physical property losses during building construction. [10](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms")

## Key Differences in Builders Risk Insurance

### Who Writes the Policy

Chubb underwrites builders' risk itself. Marsh McLennan Agency (MMA), Marsh’s middle-market subsidiary, places the coverage through its property practice and does not issue the policy. The practical distinction is a Chubb-underwritten placement versus an MMA placement whose issuing insurer is not named on the reviewed page; neither marketing description establishes that its policy form is broader for a particular project. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

### What Delay and Soft Costs Look Like

Chubb lists delay-in-opening and asks for a soft-cost breakdown, pro forma and period of indemnity when that cover is requested. MMA’s builders’ risk subsection talks about a building under construction—additions, foundations, temporary structures and materials—but does not describe delay-in-opening as a named option. You would need the MMA quote to see whether time-element cover is even on the form. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

### Materials and Who Owns Them

MMA says coverage can include, on a limited basis, materials and supplies belonging to others as well as those the insured owns. Chubb’s reviewed page names physical-damage and related program types but does not spell out that “others’ materials” treatment. A quote should show whether suppliers’ or subcontractors’ goods on site are insured. [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance")

### How You Start a Submission

Chubb wants a project description, statement of values, locations, limits and coverage requirements. MMA says you work with a property specialist and names a National Accounts Property Practice Leader; it does not describe an online quote. The Chubb path is a documented underwriting file; the MMA path is an advisor-led placement. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## What to Confirm in Builders Risk Insurance Quotes

- Ask Chubb whether delay-in-opening is on the quote, and ask MMA which insurer would issue the layer. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance")
- Check how each form treats materials belonging to others. [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance")
- Ask whether MMA’s property-practice modeling and claims advocacy attach to this job, and whether Chubb’s loss-control is bundled or unbundled. [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance")
- Get written limits; neither reviewed page publishes dollar figures. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [9](https://www.marshmma.com/us/solutions/property.html "Property Insurance")
