Quick answer
For water damage in Antioch, GA, shut off your main valve first, or turn off the well pump breaker if you are on a private well. For a leak at the meter, call Harris County Water Works at 706-324-1175. Then call a water damage restoration company; drying should start within 24 to 48 hours, before mold sets in.
Do this first
After-hours water lines.
- Shut off the water. Shut the main valve at the meter box or where the line enters the house; on a private well, switch off the pump breaker. With no town government, Antioch homes on public water are Harris County Water Works customers (details on our Cataula page), and septic questions go to the county office listed on our Hamilton page.
- Make it safe and document it. Cut power to wet rooms from a dry spot, photograph the damage, then report the claim.
- Start drying within 24 to 48 hours. Crawlspaces, basements, and slab homes with carpet hold moisture longer than they look.
