Sewage backup cleanup in Cloverdale: what we see
Cloverdale's older homes near downtown have older laterals, and rural properties around town often use septic. Grease, wipes and tree roots are common causes of backups.
The local picture
House age and sewer laterals. The age of the house is a good guide to the age of the lateral. Cloverdale has older homes near downtown, newer neighborhoods, and rural properties with outbuildings.
Lot, slope and trees. Long laterals, steep runs and big trees all raise the odds of trouble. Cloverdale spans the top of the Alexander Valley along Highway 101, with hillsides around town.
Neighborhoods include downtown, neighborhoods on the hillsides, and rural properties around town. Conditions vary from street to street, so a provider should look at your specific home rather than assume.
What to do right now
- Keep everyone, especially children and pets, out of affected areas.
- Stop using water: no flushing, showers, dishwasher or laundry.
- Don't touch sewage without boots, gloves and eye protection.
- Photograph the damage for insurance.
- Call a plumber for the cause and a restoration provider for cleanup.
