## 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. [10](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [11](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [12](https://assets.touchpointmarkets.com/e8/58/dec27c1b462c8227b4693fb8ac81/ih-00-70-05-17-builders-risk-coverage-form.pdf "Builders Risk Coverage Form") [13](https://go.usassure.com/rs/381-ISO-510/images/us-assure-builders-risk-application-tip-sheet.pdf "Builders Risk Application Tip Sheet")

## Key Differences in Builders Risk Insurance

### Tailored Project Terms and Form Options

AIG illustrates tailoring coverage to a construction standstill and extending protection for the expected remaining term, while noting that the actual policy governs. Berkshire Hathaway Specialty Insurance (BHSI) lists all-risk, single-peril, and difference-in-conditions choices, plus primary and excess positions. For a project with unusual delay or property exposures, compare the actual proposed forms and ask which structure addresses each risk; the menu alone does not establish that a specific option is available. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [8](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk")

### Project Appetite and Underwriting Submission

AIG describes solutions for small, mid-sized, and complex projects, including domestic, multinational, and multi-year arrangements. BHSI separates its erection-all-risk and construction-all-risk target classes and says it considers Master Builder’s Risk selectively. BHSI also says underwriters may request project description, schedule, contractor loss experience, and coverage specifications. Share those details early and ask both teams to confirm fit before comparing terms. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [8](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk")

## What to Confirm in Builders Risk Insurance Quotes

- Ask AIG how the standstill and extension example would be reflected in the policy, including its conditions. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [9](https://www.bhspecialty.com/wp-content/uploads/marketing/Builders-Risk-Appetite-Guide-US.pdf "Builder’s Risk Appetite Guide")
- Ask BHSI whether the project fits its EAR/CAR appetite and whether master coverage is being considered. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [8](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk")
- Compare BHSI’s available policy forms with AIG’s proposed wording, limits, and extensions for the same project.

## Offering Details

| Criteria | AIG Builders Risk | Builder’s Risk |
| --- | --- | --- |
| Role in This Line | AIG markets Builders Risk as a construction property insurance solution for single projects and master programs. AIG is the marketing name; the page says products are written or provided by AIG subsidiaries or affiliates and does not identify the issuing company for a particular policy. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") (Evidence: Company-reported; scope: AIG’s U.S. Builders Risk product page and its general legal footer. This establishes AIG’s marketed product and issuer structure, not the insurer on an individual quote, binder or policy..) | BHSI describes primary and excess options for its Builder’s Risk products, along with single-peril and difference-in-conditions choices. [8](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..) |
| Who It’s For | The page describes solutions for a range of construction projects, including small, mid-sized and complex projects, and says AIG develops domestic, multinational and multi-year arrangements. It also describes customized options for wood-frame structures. These are marketed capabilities, not eligibility guarantees. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") (Evidence: Company-reported; scope: Project types and program configurations stated on AIG’s U.S. Builders Risk page. The page does not provide a complete underwriting appetite or state-by-state availability schedule..) | BHSI separates its EAR and CAR target categories; it says Master Builder’s Risk is considered selectively. [8](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..) |
| Coverage Features | AIG describes tailoring project coverage to construction risks and gives an example of arranging coverage for a project standstill and an extension for the expected remaining project term. These examples do not establish that any buyer is entitled to a standstill extension or that it is included in a policy. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") (Evidence: Company-reported; scope: AIG’s illustrative Builders Risk marketing examples. The page directs interested buyers to the actual policy for coverage scope, limitations, terms, conditions and exclusions..) | BHSI describes Builder’s Risk as project property coverage and lists hot testing/commissioning, delay and soft-cost features. [8](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. [8](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. [9](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..) |
| Limits and Retentions | The reviewed product page does not state a standard policy limit, deductible or retention. AIG says coverage depends on the actual policy language; confirm the applicable amounts and conditions in the quote and issued policy. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") (Evidence: Not publicly disclosed; scope: AIG’s U.S. Builders Risk marketing page as reviewed on 2026-09-30. No buyer-specific quote, declarations or policy form was reviewed; this is not a finding that such terms are unavailable from AIG..) | Confirm in your quote. |
| Risk Services | AIG says its risk engineers can work with clients on loss-prevention improvements and customized service plans, including loss-control reports. The page describes these as risk services and does not make them policy coverage or a guaranteed loss outcome. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") (Evidence: Company-reported; scope: Company-described services on the U.S. Builders Risk page; availability for a particular account is not specified..) | Confirm in your quote. |
| How to Apply | Confirm in your quote. | BHSI says underwriting may request coverage specifications, a project description, contractor loss experience and a construction schedule, among other project details. [9](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..) |
| Claims Support | AIG states that, after property-damage coverage is confirmed, it promises working funds equal to 50% of its share of the agreed property-damage estimate within seven days. This is AIG’s stated claim-funding service condition; the page does not make it a general claim-payment deadline or establish policy entitlement for every loss. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") (Evidence: Company-reported; scope: Conditional company statement on the Builders Risk page. It applies only as described there and remains subject to the actual policy and claim circumstances..) | Confirm in your quote. |

## AIG Reviews

Review Score: 4.4 / 10 from 2 rated sources, equally weighted.

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.

- NerdWallet: NerdWallet editorial rating 2.5 (stars). NerdWallet’s editorial business-insurance comparison; the AIG entry concerns commercial liability and property insurance, not a quantified policyholder-review sample. The page’s complaint statement and 2.5-star editorial rating are source-specific and must not be recast as a consumer average. Checked 2026-09-29.

## Berkshire Hathaway Specialty Insurance Reviews

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.
