Do this first
Local water and septic lines.
- Shut off the water. Many Sweet Home farmhouses run on a private well. Flip off the pump breaker first so it stops pushing water, then close the valve at the pressure tank or where the line enters the house.
- 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. About 62% of homes around Sweet Home were built before 1980, and older frame houses hold water under the floor, so ask for readings in the crawlspace as well as the walls.
Mustang Creek runs just north of Sweet Home, and FM 318 and FM 531 cross low ground. If water covers the pavement, turn around. Water that crossed a pasture or a drain field should be handled as sewage.
