Cleveland Fire Service says that arson attacks cost Teesside's economy nearly £17 million a year. Around 75% of all fires dealt with by the brigade are started deliberately.
The price of putting out the fire, as well as destroyed property and possessions, costs the borough more than £300,000 a week.
The service launched an awareness campaign to coincide with the school holidays, a time when incidents of arson tend to increase.
In total, there were 3,029 arson incidents across the Cleveland force area last year.
Diana Khan is one of the those affected by an arson attack on a parade of shops in Eaglescliffe earlier this year. She has a second hair salon in nearby Yarm and says she is lucky she has been able to keep her business going.
