Coverage Built for Your Industry’s Real Risks


General Liability:

Third-party injuries, property damage, and completed operations... crucial in California where defect lawsuits and client contracts demand robust protection. We ensure you have the right Additional Insured endorsements and completed ops coverage for up to 10 years.


Workers’ Compensation:

For all employees protection, from drivers to sales. We help you manage mod scores, improve safety, and lower costs.


Special Programs for Building Material Suppliers:

Product liability for your goods, inland marine for inventory in transit, property insurance for warehouses—plus proof of insurance for your contractor clients. We know the ins and outs of both manufacturing and supply chain risks.


Inland Marine (Tools & Equipment):

Covers heavy equipment and tools wherever the job takes you, reducing the financial sting of theft or damage.


Commercial Auto & Fleet:

Insures your trucks, vans, and delivery vehicles. Plus, any on-road liability for moving materials.


Surety Bonds:

From the $25,000 contractor license bond to bid, performance, and payment bonds for public and private jobs. We help you stay compliant and competitive.


Excess Liability:

Larger jobs often require umbrella/excess limits up to $5M or $10M. We arrange coverage that keeps you qualified for major contracts.
