Before you sign
What to ask a San Jose contractor first
- 01
For a slab leak, is a spot repair through the concrete or an overhead reroute proposed, and why that choice?
- 02
Will a written report with photographs and marked locations be provided, since insurers usually require proof of cause and position?
- 03
Which detection methods are included — acoustic listening, thermal imaging, tracer gas or a meter isolation test — and in what order?
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 Jose Planning, Building and Code Enforcement — 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 Jose — 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 Jose?
Permits in San Jose are issued by San Jose Planning, Building and Code Enforcement. 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.
Does calling create any obligation to hire?
None. A call or a callback request is a conversation, not a contract. Scope, timing and price are only agreed if you decide to proceed with the professional handling San Jose.
Are night and weekend calls handled differently in San Jose?
Requests route around the clock, but most contractors price after-hours work differently. Ask for the after-hours rate and a committed arrival window before agreeing to a dispatch.
What information speeds up a leak detection callback?
Three things: where the water or problem is showing, whether the supply is shut off, and the property type — slab, crawl space or basement. With those, a pro covering San Jose can triage the urgency and bring the right parts.
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.
