About Us

Experts in septic system, pumping, inspection, repair, installation and portable toilet rentals 

Let's face it, keeping your septic system in good working order is one of the few chores you'd rather leave to someone else.  But choosing the right “someone” is critical. Without competent,  professional maintenance you could one day have an expensive mess on your hands. If you're installing a new system, you want that same high level of competence in your installer. Both are good reasons to trust Castle Septic Service Corporation.  We've earned the confidence of septic owners throughout Northwestern New Jersey.

  • Septic Tank Cleaning and Pumping
  • Septic Tank and Septic System Design & Installation
  • Septic Tank Inspection and Troubleshooting
  • Septic Repairs and Maintenance
  • Drain Field Repair
  • Consulting
