Leak detection is a search for the source; it does not necessarily include repairing it. Compare proposals using the area investigated, billing limits, and what documentation or access work is included.
Price evidence and its limits
No verified national fee is established here for a leak search. Request a diagnostic offer specifying the suspected systems, search area, included time or fixed deliverable, and authorization limit. The price of repairing a confirmed leak is a separate question from the fee for locating it.
Define the work in the quote
Problem history
Provide where and when water appears, meter observations, and any previous repairs. Ask which plumbing or building systems are included in the investigation.
Methods and limits
Request the proposed approach and why it fits the suspected problem. Set an initial time or price authorization and ask what happens if the leak is not located within it.
Confirmation and repair
Ask whether the deliverable is a suspected location, a confirmed source, or a written report. Separate opening walls or floors, pipe repair, and restoration from the diagnostic price.
Set a useful investigation deliverable
Ask what evidence the investigator will provide: photographs, a report, test results, or a marked suspected location. Agree whether opening surfaces is included and whether repairs need a separate contractor. If the first method does not locate the leak, require a revised scope before further billing. A fixed search fee and an open-ended hourly investigation should not be compared as equivalent offers.
The key question before authorizing work
Ask: What will the investigation deliver, what is the authorized limit, and are opening surfaces or repairs excluded?
