The Better Business Bureau (BBB) of Minnesota is warning homeowners about “storm chasers”–who try to take advantage of those who have been impacted by natural disasters like tornadoes, flooding, and wildfires.

“Some of these scammers may lack proper licensing or offer quick fixes or make big promises that they are unable to deliver.”

The BBB’s Bao Vang says if you’ve been impacted by a natural disaster, contact your insurance company. And she says resist high-pressure sales.
