More than 400 volunteers from 10 states plan to descend on the Canonsburg area Sunday for a weeklong work camp to help residents with sorely needed home repairs.

About 14 groups, including 50 members of the Canonsburg United Presbyterian Church youth group, are offering the free work as part of the Group Cares program.

Gary Lucas, coordinator for the local contingent — called the Chartiers Creek Workcamp — said he and his group of 14- to 20-year-olds began taking applications from local senior citizens, disabled residents and low-income families a year ago.

“We sent out applications with church bulletins, yard signs and even pizza boxes,” said Mr. Lucas, whose group has participated in seven similar missions across the United States, from Maine to Puerto Rico.

Applications, which are no longer being accepted, were approved for 60 local residents, who will get repair work, such as painting, new porches and handicapped-accessible ramps.

“This represents about 12,000 hours of volunteer labor — worth more than $110,000 — to the community,” Mr. Lucas said.

The Loveland, Colo.-based Group Cares is a nonprofit, interdenominational, Christian, volunteer, home-repair organization. This summer, an anticipated 25,000 young people and adults will participate in 43 work camps in communities across the United States and Canada.

At each work camp, teenagers and adults — all members of church youth groups — volunteer a week of their time to repair homes throughout the community.

“These really are remarkable young people,” said Jeff Thompson, of Group Cares. “Each one is actually paying for the privilege of working in your community.”

Workcamp registration fees are used to cover costs for food, insurance and some building materials.

Local campers raised the registration fee of $449 per person through various fundraisers over the past year.

The workcamp will be housed at Canon-McMillan High School, with campers sleeping on classroom floors, eating in the cafeteria and enjoying evening programs in the gym.

This is the second work camp hosted in Canonsburg. In 2009, 363 teens from across the country made repairs for 45 area residents.
