Septic Repair and Drainfield Repair in Knoxville, TN
Septic repair covers the things that go wrong with a system: a failed pump, a broken baffle, a cracked distribution box, a clogged line, or a drainfield that no longer absorbs. Some repairs are small component jobs. Others are not repairs at all — a failed drainfield usually means replacement, and on Knox County's shallow, rocky ground that often means a mound system. A provider needs to see the system before anyone can say which it is, which is why repair work starts with an on-site assessment, not a price over the phone.

FAQ
How much does septic repair cost in Knoxville?
There is no published local price for generic repair — providers give a free on-site estimate, because the cost depends entirely on what has failed. As guidance only: tank-only replacement typically runs $2,000–$7,000, and drainfield replacement typically runs $5,000–$15,000 for a conventional field or $15,000–$30,000 for a mound field.
Can a failed drainfield be repaired, or does it have to be replaced?
It depends on why it failed. A clogged line or a failed distribution box can sometimes be fixed. A field whose soil is clogged with solids usually cannot be repaired — it has to be replaced, and on Knox County's shallow, rocky ground that often means a mound system. Only an on-site assessment can tell which it is.
What are the warning signs of a failing drainfield?
Slow drains throughout the house, sewage smells outside, wet or soggy areas over the drainfield, unusually lush grass over the field, and sewage backing up into the house. If sewage is backing up, do not use the form — call a local emergency septic provider directly right away.
