Service · Drainfield Repair

Drainfield problems assessed honestly, fixed properly.

A wet yard or backed-up drains can mean anything from a broken lateral to a drainfield that has saturated over the years and cannot recover. We find out which situation you are in before recommending repair or replacement. No upselling a full replacement when a targeted fix will do the job.

What We Repair

The drainfield is the part that fails, and the part that matters most

The tank holds and separates. The drainfield disperses. When the drainfield stops working, the whole system backs up, and the longer it goes without attention, the harder the eventual fix becomes. Biomat builds up in the soil, saturation spreads, and what might have been a localized repair becomes a full field replacement.

We diagnose drainfield problems the same way we diagnose anything else: we look at the actual system rather than guessing from the surface symptoms. That means checking the distribution lines for breaks or blockages, examining the field laterals, assessing the soil condition, and evaluating whether the failure is mechanical (fixable) or hydraulic (the soil itself is exhausted).

In Central Texas and the Hill Country, soil conditions vary significantly. Expansive clay, shallow limestone, and caliche layers all affect drainfield longevity and failure patterns. A drainfield that was designed for the soil profile on your property will last longer than one that was not. When we repair or replace a field, we take the existing soil conditions into account, not just the footprint of the old system.

What drainfield repair includes

  • On-site assessment with root-cause determination
  • Distribution box inspection and repair or replacement
  • Broken or crushed lateral repair or replacement
  • Partial field extension where soil allows and lot permits
  • Full drainfield replacement with new design where required
  • County permit filing where the scope requires it
  • Clean excavation and site restoration after work
  • Written scope and firm price before work begins

When the drainfield cannot be repaired

Some drainfields are too far gone to repair. When that is the case, the right answer is a properly designed replacement, not a patch that delays the inevitable. We are direct about that threshold. If your site needs a full replacement, we handle the design, permit, and installation under one license. See our upgrades and replacements service.

Drainfield FAQ

Common questions

Wet, soggy, or unusually lush patches of grass over the drainfield area are the most visible sign. Sewage odors in the yard, slow drains throughout the house, and gurgling plumbing fixtures also point toward the drainfield. Any of these signs warrant an inspection. Catching the problem early gives you more options. A partially failed field is much cheaper to address than one that has been saturating for years.
It depends on the failure mode. A broken lateral or crushed pipe is often repairable. A drainfield that has been saturated for years and has a dense biomat layer choking the soil typically cannot be rehabilitated and requires a new field. We assess honestly and tell you which situation you are in before recommending anything. We do not push replacement when repair is a legitimate option.
Significant drainfield work generally requires a county OSSF permit, especially when the field is being expanded or redesigned. Minor component repairs may not. We determine what your specific situation requires and handle any permit filing as part of the job.
Cost depends on the extent of the failure, the soil conditions, and whether the existing field can be extended or must be fully replaced. Localized repairs cost considerably less than a full field replacement. Full drainfield replacement is in the range of a substantial system repair. We give you a firm scope and price after assessing the site, not a range over the phone that ends up meaning nothing.
