What Actually Changes the Price
Depth & Access
A leak under an open lawn costs less to reach than one under a driveway, patio, or mature landscaping.
Number of Suspect Areas
A single confirmed leak location costs less to test than a whole-house sweep with multiple possible sources.
Detection vs. Repair
Finding the leak and fixing it are priced separately. Detection confirms the problem; repair cost depends on what’s found.
Frequently Asked Questions
Is leak detection worth the cost compared to just waiting?
Almost always. A pinhole leak gets larger over time, not smaller, and the cost of water damage, mold remediation, or foundation repair from a leak left running for months is typically many times the cost of an inspection.
Does the detection fee count toward the repair cost?
This varies by company and situation. Ask upfront when you schedule — we’ll always be clear about how our pricing works before we arrive.
Why do prices vary so much between companies?
Equipment, experience, and business model all factor in. A company running acoustic and thermal equipment daily tends to price and diagnose more precisely than a general plumber doing leak detection occasionally.
Will my quote change after the inspection?
It can, if the inspection reveals something more complex than expected — for example, what looked like a single spot leak turns out to be a failing line that needs a full reroute. We’ll always explain why before moving forward.
Is there a cheaper DIY option before calling a professional?
A basic water meter check (confirming the leak-indicator dial moves with everything off) is free and worth doing first. Beyond that, pinpointing the exact location without professional equipment usually isn’t realistic.
