Drain Field Repair — Find Verified Companies Near You
Repair or replacement of failing drain fields (leach fields) including soil remediation, pipe replacement, and alternative system design.
The drain field (also called a leach field) is the most expensive component of your septic system to repair or replace. When it fails, wastewater can't be properly absorbed and filtered by the soil, leading to surface breakouts, contamination, and potential health hazards.
Signs Your Drain Field Is Failing
- Standing water or soggy ground over the drain field area
- Sewage odors in the yard
- Unusually lush, green grass over the drain field
- Slow drains and gurgling pipes throughout the house
- Sewage backup into the home
Repair Options
- Aeration/rejuvenation: Injecting air into the soil to break up the biomat (biological clog). Cost: $2,000–$5,000.
- Partial replacement: Replacing damaged sections of pipe or adding additional drain lines. Cost: $3,000–$10,000.
- Full replacement: Excavating the old field and installing a completely new drain field. Cost: $10,000–$20,000+.
Prevention
The best way to protect your drain field is proper septic maintenance: pump on schedule, conserve water, and never drive or build over the drain field area.
