## Chubb vs Marsh Builders Risk Insurance Summary

Chubb offers individual-project and master policies with delay-in-opening cover; Marsh McLennan Agency places builders risk within a property practice covering buildings under construction. [1](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [2](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## What Are the Key Differences Between Chubb and Marsh Builders Risk Insurance?

### Who Writes the Policy

MMA describes builders risk as coverage for buildings under construction within its broader property practice. Chubb’s builders-risk offering specifically lists individual-project and master programs, plus delay-in-opening coverage. [1](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [2](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. [1](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [2](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. [2](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [1](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. [1](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [2](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## What Should You Confirm in Chubb and Marsh Builders Risk Insurance Quotes?

- Ask Chubb whether delay-in-opening is on the quote, and ask MMA which insurer would issue the layer. [1](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [2](https://www.marshmma.com/us/solutions/property.html "Property Insurance")
- Check how each form treats materials belonging to others. [2](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [1](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. [2](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [1](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance")
- Get written limits; neither reviewed page publishes dollar figures. [1](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [2](https://www.marshmma.com/us/solutions/property.html "Property Insurance")
