DFW Septic Service

Septic Tank Cleaning (Full Clean-Out)

A standard pump-out removes liquids and most sludge. A full septic tank cleaning goes further — evacuating hardened bottom sludge, scraping biomat off the tank walls, back-flushing, and re-inspecting baffles. Best choice if your tank hasn't been serviced in years or if you've seen recurring slow drains.

What's Included

  • Complete sludge & scum evacuation
  • Tank-wall biomat scraping
  • Back-flush & rinse
  • Baffle, tee & filter inspection
  • Both compartments serviced
  • Lid reseat & seal
  • Written condition report

When to choose full cleaning over routine pumping

Pumping is the right call most years. Pick full cleaning if the tank hasn't been opened in 7+ years, if you just bought a home with unknown service history, if drains have been slow after a recent pump-out, or if a real-estate inspector flagged heavy biomat.

Frequently Asked Questions

What's the difference between septic pumping and septic cleaning?+

Pumping removes liquid and most sludge. A full cleaning evacuates everything — including hardened bottom sludge and biomat on the tank walls — then back-flushes the tank. Cleaning is recommended every 2–3 pumping cycles or after long maintenance gaps.

How long does a septic tank cleaning take?+

About 90–120 minutes on site, roughly twice the time of a standard pump-out.

How much does septic cleaning cost in DFW?+

Typically $475–$750 for a 1,000–1,500 gallon residential tank, depending on tank depth and lid access.

Will cleaning fix my slow drains?+

If the cause is an over-full tank or built-up sludge, yes. If the drain field is failing, cleaning won't solve the underlying problem — we'll diagnose before we quote.
