The following factors affect the cost of a septic inspection:
Inspection type – A routine inspection for regular maintenance costs less than a full inspection for a real estate transaction.
Inspection level – A visual inspection or dye test costs less than a full system inspection but may not detect all problems.
Septic tank size and depth – Inspection costs increase for larger or deeper tanks.
Digging required – Some septic companies charge extra to dig up the septic tank cover.
Accessibility – Prices increase for septic systems on steep slopes or in difficult-to-access areas.
Location – Some cities require an inspection from a licensed septic contractor, while others allow a home inspector to perform the inspection.
Combining inspections – Most companies offer a discount when combining septic, well, and home inspections.
A septic camera inspection costs $125 to $500. A comprehensive septic inspection often requires a fiber optic camera to examine inside the septic and drain field lines.
Septic tank repairs cost $600 to $3,000, depending on the problem and which parts need replacing.
Leach field rejuvenation costs $1,000 to $5,000.
Drain field replacement costs $3,000 to $15,000.
Well and septic inspection
A well inspection costs $250 to $550 on average, depending on the well type and depth and whether the inspection includes laboratory water testing for bacteria and other contaminants. Most companies offer discounts when combining well and septic inspections in the same visit.
Septic pumping and inspection cost
Septic tank pumping costs $295 to $610 on average, depending on the tank size. A comprehensive septic inspection typically includes pumping the tank. Most companies charge separately for pumping the tank before a basic or visual inspection.
Septic inspection cost when buying a house
A septic inspection costs $300 to $650 when buying a house. Most buyers schedule a home inspection within 3 to 10 days of signing the contract. The home inspector performs a visual septic inspection. Buyers typically only schedule a comprehensive septic inspection if the home inspection uncovers potential septic problems.
If the septic system fails inspection, the buyer may use that information to negotiate a discount on the home purchase price or require the seller to repair the system.
The seller is legally obligated to disclose any known problems with the septic system to potential buyers.
Septic tank inspection cost by location
Septic inspection costs depend on local city or state regulations. Prices for a routine septic inspection are typically higher in states with Title V or similar requirements. For example:
A septic tank inspection in Atlanta, GA costs $100 to $200 for a visual inspection or $200 to $450 for a basic inspection. A full septic inspection for a realty transaction costs $300 to $600+.
A septic inspection in Florida costs $250 to $500.
A Title V septic inspection in Massachusetts costs $400 to $800 and is required every 2 to 3 years.
Title 5 inspection cost
A Title 5 inspection costs $300 to $650 and is required in some states for the sale or transfer of a home or the addition of a bedroom, bathroom, or swimming pool. The homeowner or seller pays for the septic inspection. Many states mandate septic inspections every 2 to 5 years.
What happens during a Title 5 inspection?
A Title 5 inspection is a comprehensive evaluation of the septic lines, tank, and drain field.
The inspector gathers information about the system based on the size of the household, septic tank size, previous permits, and as-built plans.
The septic company pumps the tank before the inspection. Some companies include pumping in the inspection cost.
The inspector locates all septic system components—including the sewer lines, tank, distribution box, and drain field—and checks each part for signs of hydraulic failure.
Accessing the tank may require digging if there are no risers on the surface. The inspector also digs 2 to 3 feet down to confirm proper drainage.
The inspector tests the plumbing in the home by flushing toilets, running water in the sinks and tubs, and running the washing machine through a full cycle.
The inspection company provides the results to the homeowner and local Board of Health.
