Before you sign
What to ask a San Diego contractor first
- 01
Will a written report with photographs and marked locations be provided, since insurers usually require proof of cause and position?
- 02
Which detection methods are included — acoustic listening, thermal imaging, tracer gas or a meter isolation test — and in what order?
- 03
Is the detection charge separate from the repair, and does it still apply if no leak is ultimately located?
Before anyone touches a pipe
Verify the license. It takes two minutes.
- Who licenses the work: Contractors State License Board (CSLB).
- Who pulls the permit: San Diego Development Services — the licensed contractor, never the homeowner.
- What to ask for: the license number, the registered name behind it, and an insurance certificate issued to the property address.
Answers first
Leak Detection in San Diego — common questions
How do I know if I have a hidden leak?
The simplest test: turn off every fixture and appliance that uses water, then watch the water meter's low-flow indicator for 15–20 minutes. Any movement means water is leaving the system somewhere. That test does not tell you where — it tells you that detection is worth paying for.
Is a slab leak an emergency?
It is urgent rather than instantaneous. A slab leak will keep eroding fill under the foundation and driving up the bill for as long as it runs, so it should be located quickly — but you generally have hours to days, not minutes, unless water is entering the living space.
Will detection damage my floor?
Modern detection is designed to avoid that: the point of acoustic, thermal and tracer-gas equipment is to make one small opening instead of several exploratory ones. Ask the contractor what restoration is and is not included before work starts.
Do I need a permit for plumbing work in San Diego?
Permits in San Diego are issued by San Diego Development Services. As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.
How should a leak detection quote be compared?
Line by line against scope: what is included, what is excluded, who pulls the permit, and whether haul-away and restoration are inside the number. The cost guides on this site list published third-party ranges so any quote can be sanity-checked.
Who handles the permit for leak detection in California?
The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the license.
What warranty applies to the work?
Whatever the contractor offers in writing — PlumberCalifornia is not a party to the agreement. Ask for labor and parts warranty terms in the quote, and keep the license number with the paperwork.
How does the callback request work?
The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.
