Septic Inspections for Buying and Selling in Gregg County

A septic problem found a week before closing is a negotiation. Found a week after, it is yours.

What an inspection actually covers

  • Locating the system and confirming it matches what is on file with the authority
  • Opening and measuring the tank: sludge and scum levels, baffles, structural condition
  • Running water to see how the system responds to real flow
  • Walking the drainfield for ponding, soft ground, odour and surfacing
  • On a powered system: the compressor, pumps, floats, alarms and disinfection stage
  • Checking the paperwork trail, which is often the part that decides the deal
The records matter as much as the hardware

A system in good physical condition with no approval on file, or with a lapsed service obligation, is still a problem. What a buyer's lender wants to see is a documented, compliant system, and documents cannot be produced retrospectively. Get an inspection quoted →

If you are selling

  1. Find the paperwork now

    The permit, the approval, the as-built drawing, service reports and pump-out receipts. Missing documents take time to replace, and time is what you do not have once a buyer is in.

  2. Pump the tank before the inspection

    Not to hide anything: an empty tank is the only condition in which the baffles and the outlet can actually be seen and certified as sound.

  3. Bring any service contract current

    A lapsed contract on a powered system is a visible, dated gap in the record.

  4. Get ahead of anything obvious

    Soft ground, a smell, an alarm you have been ignoring. A known issue you have priced is worth vastly more at the table than a surprise the buyer's inspector finds.

If you are buying

Have the system inspected by someone independent of the seller, ask for the full document history, and find out what the ongoing obligation is before you commit rather than after. On an older system, ask specifically when the drainfield was installed: a field at the end of its working life is a five-figure item that no inspection report will describe as broken, because on the day it is not.
