AIG vs 
Marsh: How Do They Compare for Builders Risk 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. 1,2
What Is Marsh?
Marsh suits technology and larger businesses seeking specialist cyber placement or broad global risk advice; small firms wanting a quick standard quote should compare its MMA route or digital agencies. 4,5,6,7
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. 9,10,11,12
Key Differences in Builders Risk Insurance
Construction Materials and Structures
Marsh’s middle-market property practice says builders risk can address foundations, additions and alterations, temporary structures, and materials owned by the insured; coverage for others’ materials is limited. AIG describes customized options for wood-frame structures. If the project uses nonstandard framing or stored materials owned by subcontractors, ask each provider to identify those items and ownership conditions in the quote. 3 8
Project Advice and Schedule Changes
AIG illustrates a standstill with an extension for the expected remaining construction term. Marsh lists valuation, hazard assessment, catastrophe modeling, claims advocacy, and pre- and post-loss risk control. The practical contrast is between AIG’s stated schedule example and Marsh’s broad property-advisory toolkit; confirm the proposed extension and which Marsh services will be assigned to the account. 3 8
What to Confirm in Builders Risk Insurance Quotes
- Ask Marsh how the form treats materials belonging to subcontractors and AIG how its wood-frame option applies to the project design. 3 8
- Ask AIG to state the conditions for a standstill extension and Marsh which risk-control or valuation services are included. 3 8
- Identify the placing entity and insurer because Marsh’s cited service is provided through its middle-market subsidiary. 3 8

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.[1][2]

Marsh’s global Trustpilot profile has a poor 1.3/5 score. Treat it as a service warning to investigate with your proposed team; it does not isolate US commercial accounts.[2][4][7]

AIG vs Marsh: Builders Risk Insurance: documented features by provider
| Criteria | AIG Builders Risk | Marsh McLennan Agency Builders' Risk Insurance |
|---|---|---|
| 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. 3Company-reported. 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. | Marsh McLennan Agency (MMA), Marsh's middle-market subsidiary, places builders' risk insurance as part of its broader property insurance practice, not as a separately branded product. 8Company-reported. MMA property insurance page, Builders' Risk subsection. |
| Issuing Insurer | Confirm in your quote. | The reviewed page does not name a specific builders' risk insurer. 8Not publicly disclosed. MMA property insurance page as read on 2026-09-23. |
| 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. 3Company-reported. 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. | Confirm in your quote. |
| 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. 3Company-reported. AIG’s illustrative Builders Risk marketing examples. The page directs interested buyers to the actual policy for coverage scope, limitations, terms, conditions and exclusions. | MMA says builders' risk coverage addresses risks unique to a building under construction, including additions and alterations, foundations, temporary structures, and materials and supplies owned by the insured, and on a limited basis, materials and supplies belonging to others. 8Company-reported. MMA property insurance page; illustrative description, not a specific policy form. |
| Limits and Retentions | The reviewed product page does not state a standard policy limit, deductible or retention.

| 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. 3Company-reported. Company-described services on the U.S. Builders Risk page; availability for a particular account is not specified. | MMA says its property practice offers hazard assessment and valuation services, loss and catastrophe modeling, claims advocacy, pre- and post-loss risk control, and program design expertise drawn from its global market experience. 8Company-reported. MMA property insurance page, Benefits of Property Insurance and Builders' Risk sections; these services are described for the property practice generally, not exclusively for builders' risk. |
| How to Apply | Confirm in your quote. | You work with an MMA property specialist directly; the page names a National Accounts Property Practice Leader and describes advisor-led placement rather than an online quote. 8Company-reported. MMA property insurance page. |
| 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. 3Company-reported. 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. |
