In the US, excess in a policy typically refers to an additional policy or coverage. If you have an excess policy, it will provide coverage after you’ve exhausted your standard policy limits.
For example, if you have $250,000 worth of coverage and the damage to your home is $300,000, an excess policy, or umbrella policy, would cover the additional $50,000.
As the definition of excess varies, it’s best to contact your home insurance company. An agent can help you understand the terms and conditions within your policy to ensure you know what coverage you have.
