At Mainline Insurance, we have been providing your small business with commercial liability insurance policies to keep your business running smoothly since 2006. We are located in San Diego, CA, but we do business throughout California and in a few other states. We work with a range of insurance providers to offer you multiple policy choices. We explain each available policy in clear and understandable terms, so you can choose which policy is right for you. We save you time and money by finding the right coverage to protect you and your company at a price that fits your budget. We look and feel very different from your average contractors insurance provider. Our goal is to put your best interest first.

At Mainline Insurance, we want to take the time to show you just how different we are from other insurance providers. Other insurance agencies can charge you excessive fees or high deposits. They have also been known to add hidden exclusions to their policies, leaving you without coverage when you need it most. It takes a lot of time to read through different policies and compare prices, time you could be spending building your business. Let Mainline do that work for you. We promise to find you the best policy for you, with our honest and helpful guidelines. Here are some of our guidelines for doing business with you:
