How much does leach field repair cost?
Short answer
Published guides put leach field repair at about $1,000 to $5,000, with hydro-jetting from $250 to $800 and line replacement at $20 to $45 per foot. These are third-party, unverified estimates. A fully clogged field may need replacement instead, so have the cause confirmed before you pay for any repair.
The bill depends on what's actually wrong. Fixing one broken pipe and dealing with a field that's clogged from end to end are very different jobs.

Which repairs might help?
- Fixing a damaged line. A reasonable option for a crushed or broken section.
- Redirecting water. Fixing leaks or moving roof drains costs little, and it may be all you need.
- Jetting or rejuvenation. Cost guides list these, but we found no independent evidence of how well they work. Ask for the reasoning and any guarantee in writing.
When isn't a repair enough?
When the soil itself is clogged. NC State Extension says fully clogged soil usually needs a new drainfield, an advanced pretreatment unit, or both, and that pumping alone gives only a few days of relief.
How can you avoid paying for the wrong repair?
- Have the cause confirmed with an inspection.
- Report the problem to your local health department.
- Get written estimates from more than one provider.
- Check whether the work needs a permit.
NC State Extension advises against attempting repairs without the health department's approval. If cost is a worry, financial help may be available, as our replacement guide explains.
