A complete septic inspection typically ranges from $300 to $600, depending on your system’s complexity and accessibility. This includes locating and accessing the septic tank, evaluating all components, testing the drain field, and providing a comprehensive written report.
The inspection covers tank condition, liquid levels, inlet and outlet baffles, distribution box functionality, and drain field performance. You’ll also receive documentation that meets Suffolk County requirements for real estate transactions or compliance reporting.
Additional costs might apply if extensive excavation is needed to access components or if dye testing is required to identify specific issues. However, most standard inspections can be completed without additional charges, and you’ll know the total cost upfront before any work begins.
