## What Is Builders Risk Insurance?

Builders risk protects the project you are building, including materials meant for it, against physical loss until construction ends. The gaps that cost owners money are materials in storage or transit, the existing building in a renovation, and coverage ending when you occupy early. [9](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [11](https://assets.touchpointmarkets.com/e8/58/dec27c1b462c8227b4693fb8ac81/ih-00-70-05-17-builders-risk-coverage-form.pdf "Builders Risk Coverage Form") [12](https://go.usassure.com/rs/381-ISO-510/images/us-assure-builders-risk-application-tip-sheet.pdf "Builders Risk Application Tip Sheet")

## What Are the Key Differences Between Harper and Liberty Mutual Builders Risk Insurance?

### One Market Search or a Named Insurer Product

Harper says it takes one application for construction risk and presents options from markets that write construction, using admitted markets where pricing allows and excess-and-surplus lines when the work requires them. Liberty Mutual lists a named proprietary form as well as a stand-alone Specialty Property offering. Harper's route is a broker-led market search; Liberty Mutual's public material identifies its own product options. Ask who will issue the final contract and compare forms, not just the application experience. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [8](https://business.libertymutual.com/commercial-solutions/inland-marine/builders-risk "Builder’s risk")

### What the Public Coverage Descriptions Name

Harper describes protection for a project's structure, materials, and fixtures from ground break to handover, alongside jobsite liability and required certificates. Liberty Mutual lists materials, labor, construction-management fees, temporary structures, and landscaping materials during construction, while noting that terms vary by form. A project with contract-driven certificate requirements should separate those documents from the builders-risk policy that protects the work itself. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [7](https://business.libertymutual.com/commercial-solutions/property/ "Property")

## What Should You Confirm in Harper and Liberty Mutual Builders Risk Insurance Quotes?

- Ask Harper which carriers were approached, what form was selected, and whether certificates or jobsite liability are separate from builders risk. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance")
- Ask Liberty Mutual which product form is proposed and how it schedules fixtures, materials, and landscaping through handover. [7](https://business.libertymutual.com/commercial-solutions/property/ "Property")
- Compare project values, deductibles, and exclusions in the actual policy proposals. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [8](https://business.libertymutual.com/commercial-solutions/inland-marine/builders-risk "Builder’s risk")

## Harper vs Liberty Mutual Builders Risk Insurance Compared

| Criteria | Harper Builders Risk Coverage | Liberty Mutual Builder’s Risk |
| --- | --- | --- |
| Role in This Line | Harper places builders risk as one piece of its Construction & Contractors insurance package, describing itself as calling every market that writes construction and presenting the options back, rather than underwriting the coverage itself. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Company-reported; scope: Construction & Contractors industry page; describes Harper's placement role for the package that includes builders risk, not a standalone builders risk product page..) | Liberty Mutual lists Builder’s Risk in its property portfolio and describes both a named proprietary form and a stand-alone Specialty Property offering.

It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents..) |
| Issuing Insurer | The reviewed pages do not name the insurer or insurers that would issue a builders risk policy Harper places; the industry page refers only to 'every market that writes construction' without listing carriers. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Not publicly disclosed; scope: Checked the Construction & Contractors industry page and homepage industries carousel on 2026-09-23; a specific insurer would appear on the quote or policy..) | Confirm in your quote. |

| Coverage Features | Harper describes builders risk as covering the structure, materials and fixtures of a project from ground break to handover, alongside jobsite liability and the certificates a project requires to start. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [4](https://www.harperinsure.com/ "Harper Homepage") (Evidence: Company-reported; scope: Construction & Contractors industry page coverage callouts and homepage industries carousel; the issued policy and declarations would control actual terms..) | The builder’s-risk page describes protection during construction, including materials, labor, construction-management fees, temporary structures and landscaping materials; actual coverage remains form-specific.

| Limits and Retentions | Harper's reviewed pages do not publish builders risk limits, deductibles or maximum project values; the industry page says cost depends on trade, payroll and revenue and is quoted individually across multiple markets. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Not publicly disclosed; scope: Construction & Contractors industry page FAQ 'What does it cost?'; no published limit or retention figures found..) | The cited public overview does not establish the limits, deductibles, exclusions or form terms that would apply to a specific buyer.

| Risk Services | Harper says it writes certificates of insurance with additional-insured, waiver-of-subrogation and primary-and-non-contributory wording the same day a contract calls for it, and checks subcontractors' certificates so their risk does not become the general contractor's. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Company-reported; scope: Construction & Contractors industry page; describes the certificate and risk-review service Harper says it provides around construction projects, which includes builders risk jobs..) | Liberty Mutual describes property underwriting, risk-engineering and claims teams working together on complex property risks.

| How to Apply | Harper says it takes one application for construction risk, including builders risk, and quotes it across every market it says writes construction, admitted where pricing allows and excess-and-surplus lines when the work demands it.
