## 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. [12](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [13](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [14](https://assets.touchpointmarkets.com/e8/58/dec27c1b462c8227b4693fb8ac81/ih-00-70-05-17-builders-risk-coverage-form.pdf "Builders Risk Coverage Form") [15](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 Berkshire Hathaway Specialty Insurance and StartupInsurance.ai Builders Risk Insurance?

### A product line versus a catalogue entry

BHSI separates its EAR and CAR target categories and says Master Builder's Risk is considered selectively [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk"). StartupInsurance.ai lists builders risk as one of seven physical-risk lines framed around founders building robots, hardware, energy or defense tech [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review").

### Who carries the risk

StartupInsurance.ai does not underwrite builders risk; a licensed agency arranges placement [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review"). BHSI describes primary and excess placements and its own forms, which points to underwriting its products directly [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk").

### How you start a quote

StartupInsurance.ai's call to action invites you to ask about requirements, and builders risk is absent from its public quote-app coverage checkboxes [9](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai"). BHSI lists the information underwriting may request, such as a project description and construction schedule [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Builders-Risk-Appetite-Guide-US.pdf "Builder’s Risk Appetite Guide").

## What Should You Confirm in Berkshire Hathaway Specialty Insurance and StartupInsurance.ai Builders Risk Insurance Quotes?

- Which insurer would write a StartupInsurance.ai builders risk policy? The homepage names six program-level carriers but not one for this line [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")
- What project values, perils and policy periods apply? StartupInsurance.ai's reviewed pages publish none [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")
- Does your project fall into a BHSI EAR or CAR category? [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk")

## Berkshire Hathaway Specialty Insurance vs StartupInsurance.ai Builders Risk Compared

| Criteria | Builder’s Risk | StartupInsurance.ai Builders Risk Insurance |
| --- | --- | --- |
| Role in This Line | BHSI describes primary and excess options for its Builder’s Risk products, along with single-peril and difference-in-conditions choices. [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk") (Evidence: Company-reported; scope: These are marketed placement options, not a commitment to provide any layer or a statement about how a specific project is insured..) | StartupInsurance.ai does not underwrite builders risk coverage itself. ContractorNerd Insurance Services, LLC, the licensed property and casualty agency behind the brand, is licensed in all 50 states and arranges placement; its terms describe the company as an insurance agency/producer that does not underwrite insurance. [10](https://www.contractornerd.com/terms-and-conditions/ "Terms and Conditions") [11](https://www.contractornerd.com/insurance-licenses/ "Insurance Licenses") [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: ContractorNerd's terms and conditions and insurance-licenses page; describes the brokerage's general role, not builders-risk-specific placement terms..) |
| Issuing Insurer | Confirm in your quote. | The homepage's carrier panel names six insurers at the program level (The Hartford, Chubb, Coalition, Tokio Marine HCC, Travelers and CNA) but does not state which one, if any, underwrites a given company's builders risk policy. [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Not publicly disclosed; scope: Carrier panel is program-wide rather than broken out by line; the insurer for a builders risk placement is not disclosed on the pages reviewed and varies by placement..) |
| Who It’s For | BHSI separates its EAR and CAR target categories; it says Master Builder’s Risk is considered selectively. [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk") (Evidence: Company-reported; scope: The published target categories guide submission discussions; they do not guarantee eligibility or acceptance..) | The section frames these seven lines around founders "building robots, hardware, energy or defense tech," saying StartupInsurance.ai treats them as "our daily lines, not our exceptions" — positioning builders risk as a line it places regularly for hardware-adjacent startups with a construction or build-out project, rather than as a rare add-on. [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Same homepage section; describes the target customer segment StartupInsurance.ai says it serves for this catalogue of lines, not formal underwriting eligibility criteria..) |
| Coverage Features | BHSI describes Builder’s Risk as project property coverage and lists hot testing/commissioning, delay and soft-cost features. [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk") (Evidence: Company-reported; scope: U.S. product-page marketing summary; does not establish that each extension is included in every project policy..)<br><br>The page describes primary and excess placements and single-peril or difference-in-conditions options alongside its all-risk product description. [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk") (Evidence: Company-reported; scope: These are marketed options, not a statement that a particular quote includes them..)<br><br>BHSI lists its Builder’s Risk Form, follow-form quota-share or excess forms, and broker manuscript forms as options. [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Builders-Risk-Appetite-Guide-US.pdf "Builder’s Risk Appetite Guide") (Evidence: Company-reported; scope: A form being listed does not establish that it will be used for a project or what its final terms contain..) | StartupInsurance.ai lists Builders Risk among seven lines in the homepage's "Physical risk, because AI outgrew software" section — Products Liability, Inland Marine, Tools and Equipment, Commercial Auto, Builders Risk, Surety and Property — offered alongside the core startup program of GL, cyber, D&O and related lines. [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage "Physical risk, because AI outgrew software" section as read on 2026-09-23; the reviewed page names the line but does not describe project types, coverage period, or specific policy terms..) |
| Limits and Retentions | Confirm in your quote. | The reviewed pages do not publish sample builders risk project-value limits, covered perils, or policy-period terms. [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [9](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai") (Evidence: Not found in reviewed sources; scope: Homepage and quote-intake screen as read on 2026-09-23; limits would only surface on an actual quote..) |
| How to Apply | BHSI says underwriting may request coverage specifications, a project description, contractor loss experience and a construction schedule, among other project details. [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Builders-Risk-Appetite-Guide-US.pdf "Builder’s Risk Appetite Guide") (Evidence: Company-reported; scope: The guide gives examples rather than a universal or complete checklist; requirements depend on the submission..) | The physical-risk section's call to action reads "Ask about your insurance requirements →" rather than the "Get Quotes" button used elsewhere on the homepage, indicating builders risk is discussed with a specialist rather than quoted through a self-serve form. [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage "Physical risk, because AI outgrew software" section as read on 2026-09-23; the page does not describe what that conversation covers..)<br><br>The public quote-application's coverage-selection screen offers seven checkboxes (D&O, Cyber, Tech E&O, EPL, Fiduciary, Crime and GL); Builders Risk is not one of them, so it is not part of that self-serve intake flow. [9](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai") (Evidence: Not found in reviewed sources; scope: Initial coverage-selection screen of the quote application as read on 2026-09-23; a later screen or specialist conversation could still address this line..) |

## Berkshire Hathaway Specialty Insurance Review Scores for 2026

Review Score: not enough ratings.

The public ratings for Berkshire Hathaway Specialty Insurance are low but thin: Trustpilot shows 2.1 out of 5 from 9 reviews and BBB shows 1 out of 5 from 6. Both mix travel and commercial customers, so we don't count them in a score.
