Two Bronx men are looking to put an end to graffiti vandalism in the borough and are offering a reward to encourage others to care about their community as well.

John Provetto and John Morales are volunteering their time, money and resources to help those who live in areas that make up Community Board 10. 

"It's part of the broken window theory that if you clean up the little things, the big things don't happen," says Provetto. 

The two have spent almost four years in the communities, painting over graffiti and ripping off unwanted stickers. 
 
"We got Pelham Bay, Throgs Neck, Co-op City, City Island and Country Club probably 90 percent graffiti-free," says Morales. 

At the same time, the two are meeting with vandals in an effort to understand where they are coming from. 

The duo will be posting reward signs, offering up to $1,000, for information leading to an arrest and conviction of anyone committing graffiti vandalism.
