Martin County FL Insurance

Looking for insurance in Martin County, FL? Martin County anchors Florida’s Treasure Coast, where the Atlantic Ocean, the Indian River Lagoon, and the St. Lucie River shape the insurance picture. Hurricanes Frances and Jeanne both made landfall here in 2004 near Sewall’s Point, so wind exposure is a countywide reality. Waterfront communities like Jupiter Island and Jensen Beach also face storm surge and mapped flood zones where NFIP or private flood coverage matters, while inland Indiantown sits near Lake Okeechobee.

Cornerstone Insurance is an independent Florida agency that shops 15–20+ A-rated carriers to match Martin County residents with the right homeowners, auto, flood, and umbrella coverage. From Stuart and Palm City to the smaller communities below, choose your city to compare your options.

We have used Kyle Wilson with Cornerstone Insurance in FL for our homeowners the past 2 years. He has provided excellent customer service for us so when we recently moved we had him quote us with an auto policy. His rates were much better than the other agents we requested quotes from so now have him covering everything for us. We appreciate his quick responses along with his professionalism.

Jame did a awesome job in getting us placed with a new hoeowners policy on very short notice after our existing policy got non-renewed. He was prompt, efficient, friendly and courteous and got the job done! I would highly recommend him!
