# AIG vs CNA: How Do They Compare for Builders Risk Insurance?

AIG offers tailored project risk services and standstill examples; CNA identifies builders risk coverage and project scope but directs buyers to confirm limitations in the applicable form.

## Research Scope and Use

Use this comparison to evaluate AIG and CNA for Builders Risk Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

AIG describes builders risk arrangements for varied project types and gives a standstill-extension example. CNA lists builders risk and explains project scope and coverage limitations, so buyers should compare the proposed forms and project schedules. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [7](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance")

## What Is AIG?

AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy.

## CNA Small Business Insurance: Products, Agents and Service

CNA directs small-business buyers to independent agents and describes CNA Connect as a businessowners policy for more than 600 small-business classes.

## 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")

## Key Differences in Builders Risk Insurance

### Project Breadth and Underwriting Fit

AIG describes builders risk solutions for small, mid-sized, and complex jobs, with domestic, multinational, and multi-year arrangements and options for wood-frame structures. CNA likewise identifies builders risk by construction-project scope and calls out project limitations in its published material. For a project with an unusual structure or schedule, neither broad description is an eligibility decision; give both insurers the construction type, location, timeline, and values for underwriting review. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [7](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance")

### Project Extensions and Policy Wording

AIG’s page illustrates coverage tailored to a standstill and an extension through the project’s remaining expected term. CNA’s record highlights that its coverage limitations must be read in the applicable form. Those claims point to a practical comparison: have each insurer identify whether the same interruption scenario is covered, then review conditions, extensions, and exclusions side by side. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [8](https://www.cna.com/sites/default/files/assets/marine-capabilities-brochure.pdf "Marine Capabilities Brochure")

## What to Confirm in Builders Risk Insurance Quotes

- Ask AIG whether the standstill example can be written for your project and what conditions apply. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [8](https://www.cna.com/sites/default/files/assets/marine-capabilities-brochure.pdf "Marine Capabilities Brochure")
- Ask CNA to identify the applicable builders risk form and the project limitations that affect your construction type. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [7](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance")
- Provide both teams the same schedule, values, and project description so their quotes can be compared on equivalent facts. [3](https://www.aig.com/home/risk-solutions/business/commercial-property/builders-risk "Builders Risk Insurance") [8](https://www.cna.com/sites/default/files/assets/marine-capabilities-brochure.pdf "Marine Capabilities Brochure")

## Offering Details

| Criteria | AIG Builders Risk | Builders Risk (Inland Marine) |
| --- | --- | --- |
| 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..) | CNA lists Builders Risk under Inland Marine and Hull Builders Risk under Ocean Marine as separate catalogue items. [7](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance") (Evidence: Company-reported; scope: The catalogue categories identify separate marketed products and do not determine which form fits a specific project..) |
| 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..) | CNA’s Marine page categorizes Builders Risk under inland marine and separately lists Hull Builders Risk under ocean marine. [7](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance") (Evidence: Company-reported; scope: The categories distinguish land construction risks from marine hull projects; neither listing guarantees that CNA will quote a project..) |
| 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..) | CNA lists Builders Risk among Inland Marine coverages and describes property-damage cover for construction projects in its marine brochure. [7](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance") [8](https://www.cna.com/sites/default/files/assets/marine-capabilities-brochure.pdf "Marine Capabilities Brochure") (Evidence: Company-reported; scope: This is company marketing, not a coverage grant; policy wording and project facts control..)<br><br>The brochure gives natural-disaster, vandalism and theft as examples of project property damage the product is intended to address. [8](https://www.cna.com/sites/default/files/assets/marine-capabilities-brochure.pdf "Marine Capabilities Brochure") (Evidence: Company-reported; scope: The examples are not a complete peril list; the source directs buyers to the relevant policy for actual terms..) |
| 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. |
| 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).
