What should I do in a water damage emergency?

  1. Stop the water source only if it is safe to reach. Do not touch wet electrical equipment or enter standing water to reach a breaker; contact the utility or a qualified electrician.
  2. Keep people and pets away from standing water and electrical hazards. Move contents only when it is safe.
  3. Take photos from a safe location to document visible conditions for the insurance file.
  4. Arrange emergency help when needed and notify your insurer promptly in accordance with the policy. Gateway can help document the observed loss.
  5. Avoid unnecessary disturbance of wet or contaminated materials. Document conditions when safe, and confirm claim instructions without delaying necessary safety measures.
