How much does slab leak detection typically cost for homeowners?

Slab leak detection with Ultimate Heating & Air, Inc is offered at $79 for Same Day Service or $49 with a 4-hour arrival window, and the diagnostic fee is waived if we complete the repair. Prices vary based on how hard the leak is to access and the testing needed; final pricing is confirmed after an on-site assessment. On slab jobs, we often listen for line noise and map warm spots before opening any floor to keep disruption low. We service homes throughout the Treasure Valley, including the Middleton area.

Costs can change based on:

• Location of the leak under concrete or near walls
• Need for camera inspection or tracing multiple lines
• Age/material of piping and previous repairs
• Water damage risks that require quicker same-day diagnostics

If you notice rising water bills, damp floors, or musty odors, schedule detection promptly to avoid structural damage.
