First confirm that your property uses a septic system rather than a public sewer connection. If you’re unsure, check property records or ask your landlord or property manager before contacting a company.

Signs that may warrant a septic assessment

Slow drains, sewage odors, or unusually wet ground near a septic system may be reasons to ask for an assessment. These signs can have other causes, too, so describe what you’ve noticed rather than assuming the septic system is at fault.

What to expect from a visit

The company should explain what it plans to inspect, what access it needs, and how it will share its findings. Before work begins, ask for the proposed scope and have the company explain any recommended work in terms you understand.

Questions to ask before hiring

Ask questions specific to your system and the work being proposed.

  • Do you handle the type of septic system at my property?
  • What will you inspect, and what access should I prepare?
  • How will you explain your findings and any recommended work?
  • Will you confirm the work included before starting?
  • What information about the system would help you assess the request?

Check fit and scope before choosing

Confirm that the company handles your system type and the specific issue you’re reporting. Compare the proposed inspection or work scope, what is included, and how findings will be explained—not just the service label.

Prepare before you call

Write down the symptoms, when they started, and which fixtures or areas are affected. If available, gather system records and note any prior service. Tell the company if you’re unsure whether the property uses septic or public sewer, and ask what information it needs before scheduling.
