How much does a residential gas line inspection cost on average?

There isn’t a single “average” price for a residential gas line inspection. Costs vary by home size, line length, accessibility, and whether pressure testing or leak detection is needed. In the Dayton area, we provide upfront pricing after an on-site assessment. A licensed technician will inspect fittings, shutoff valves, and appliance connections, then confirm the total before work starts.

What affects cost:

• Line length and access
• Type of test (pressure, leak detection)
• Number of appliance tie-ins
• Any repairs found
