Behind The Price
Where this guidance comes from.
Reviewed completed-job examples
The published range uses our current $350 minimum. We checked the line items and totals of ten distinct completed residential leak-investigation jobs. Three older limited/general investigations were $175 or $275, below the current minimum; seven other investigations were $450–$550. These ten invoices contained no invoice-level discount and did not combine a separately charged permanent pipe repair. The work included visual inspections, pressure testing, acoustic or thermal investigation, and investigation of fixtures or other possible moisture sources where needed. We excluded a commercial locating job and a case focused mainly on windows and doors. This is a selected sample, not every completed job or an average. A low-end past investigation does not guarantee that price for a different locating problem. The findings and required scope determine your written proposal.
Scope: Leak investigations have a $350 minimum. The $350–$550 planning range covers different residential investigation scopes; testing and access determine your written price. Older limited investigations in the reviewed sample were below the current minimum. Permanent pipe repair is separate.

Planning range with current $350 minimum.
Different work. Different price.
Limited or general investigation
$350 minimum
The current minimum is $350. Three older reviewed invoices were $175–$275; those historical charges are not current offers. Testing, access and findings determine the scope, so this is not a price to locate every slab leak.
Other residential leak investigations
$450–$550
Seven reviewed invoices with different testing and access needs. Permanent repair was not a separately charged part of these invoices.
Repair after locating
See leak repair prices
A separate reviewed job charged $450 for detection and $660 for accessible pipe repair. The combined $1,110 was not detection alone.
What changes the price at your property?
- The suspected source: pressurized supply piping, a fixture, a drain, or another source of moisture.
- The testing and access needed to narrow down the leak.
- A limited investigation versus locating a concealed or under-slab leak.
What the work covers.
- The inspection and locating work described in your written proposal.
- An explanation of the findings and the next step for any repair.
What may be separate.
- Permanent pipe repair, major excavation, and finished-surface restoration unless listed.
- A guarantee that every moisture problem can be reproduced or located during the visit.
- An automatic detection-fee credit toward repair; confirm any credit in your written proposal.
Before you approve the work.
Make sure your written proposal explains the diagnosis, the work included, any separate items, and the total price. If something is unclear, ask. We want you to understand your options before you decide.
