They're working without getting paid.
But it's no sweat for those participating in "Project Sweat", an annual community service event where several churches and youth groups help paint houses, clean yards and rebuild structures in neighborhoods for those who are physically or financially unable to do so.
"You want people to know that they're worth it to you, that you care and we're not afraid to work for them," Scotty Crawford said. Crawford is a youth director at the First United Methodist Church in Brownwood.
He said the purpose of the "Project Sweat" is to serve, spread love and to let the community know they care.
Colton Curry is a volunteer with the church and said it's great to see the community's gratitude.
"Being able to see that sense of appreciation and humility is really amazing," Curry said.
Both Crawford and Curry agreed it is also beneficial to see everyone working as a team.
"It's cool to see them give their time. It's kind of a cool thing to see how much we can do within four days with a group of teenagers and just a few adults supervising them. It's amazing what happens with their relationships in just four days," Crawford said.
This project happens every year in June. Houses are selected based on an application process, and this year about six houses in Brownwood are lined up to get worked on.
