Geico sells auto insurance and acts as a broker for home insurance, so you’ll need to talk to the company that holds the policy. You’ll be able to get that company’s contact information if you go to Geico’s website or by calling their customer service at 1-800-841-1587.
In states like California and Florida, homeowner’s insurance is becoming much harder to find. Companies are starting to back out of offering coverage in states that are high risk due to natural disasters, such as wildfires and hurricanes. So don’t cancel your policy without a new insurer in place.
