## Marsh vs WithCoverage Commercial Property Insurance Summary

Marsh McLennan Agency helps arrange new property placements; WithCoverage audits existing property programs at no cost. [1](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [3](https://www.withcoverage.com/industries/construction "Construction Insurance & Risk Management")

## What Are the Key Differences Between Marsh and WithCoverage Commercial Property Insurance?

### Originating Coverage vs. Auditing What's Already in Place

If you are buying a new policy, Marsh McLennan Agency can assess property values and catastrophe exposure; if you already have coverage, WithCoverage says it completes an audit in about one business day after receiving your documents. Choose Marsh if you need new coverage; choose WithCoverage if you want an audit of an existing program. [1](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [3](https://www.withcoverage.com/industries/construction "Construction Insurance & Risk Management")

### A Services List vs. a Named Client Outcome

MMA's page lists categories of service in general terms — hazard assessment, valuation, catastrophe modeling and claims advocacy — without a specific client example. [1](https://www.marshmma.com/us/solutions/property.html "Property Insurance") WithCoverage instead supports its audit process with one named result:

A named construction client, Lonnie Lischka Company, is quoted saying WithCoverage delivered over $80,000 in annual savings specifically on its Property and Inland Marine program, and moved the account's insurance program and reissued more than 300 certificates of insurance in a single day before renewal. [3](https://www.withcoverage.com/industries/construction "Construction Insurance & Risk Management") (Evidence: Company-reported; scope: Customer testimonial on the construction industry page; a single client's self-reported experience, not an independently verified or typical outcome..)

### How Fast You'd See Results

WithCoverage says its no-cost audit, which includes property, is typically completed in about one business day after it receives a client's policy documents. [3](https://www.withcoverage.com/industries/construction "Construction Insurance & Risk Management") MMA's page does not publish a comparable timeline for its advisor-led placement process. [1](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## What Should You Confirm in Marsh and WithCoverage Commercial Property Insurance Quotes?

- Ask WithCoverage whether its audit could change your issuing insurer, or only identify savings within your current program. [3](https://www.withcoverage.com/industries/construction "Construction Insurance & Risk Management")
- Ask Marsh McLennan Agency for an estimated timeline for a new property placement, since its page describes services but not a process length. [1](https://www.marshmma.com/us/solutions/property.html "Property Insurance")
- Get the issuing insurer from both; neither reviewed page names one for commercial property. [3](https://www.withcoverage.com/industries/construction "Construction Insurance & Risk Management") [1](https://www.marshmma.com/us/solutions/property.html "Property Insurance")
- Ask WithCoverage which policy documents it needs to complete a property review, since its stated timeline depends on receiving them. [3](https://www.withcoverage.com/industries/construction "Construction Insurance & Risk Management")
