Leak Detection & Repair Fresno, CA
A water stain on the ceiling, a spike in your water bill, or the faint hiss of a pipe you can’t see behind drywall — hidden leaks quietly damage Fresno homes and businesses every day. Premium Plumbing & Drain Inc. brings professional, non-destructive leak detection and repair to Fresno and the surrounding Central Valley from our Turlock headquarters. Our experienced, family-owned team finds the leak the first time and fixes it right, so you’re not paying twice — once for guesswork, once for the actual repair.
What leak detection and repair involves
Leaks rarely announce themselves. Water follows the path of least resistance, so the wet spot on your floor may be ten feet from the actual break. Our job is to pinpoint the source before any drywall, slab, or landscaping gets disturbed.
We start by isolating the system — pressurizing supply lines, running a static test on the drain side, and checking the meter for movement with every fixture off. From there we use the right tool for the situation: acoustic listening equipment to hear pressurized leaks under slabs, thermal imaging to spot temperature differentials behind walls, electronic amplification for pinhole leaks, and video sewer cameras for drain and sewer line breaks.
Once located, repair options depend on the pipe type, location, and severity. That could mean a spot repair on a copper line, replacing a corroded galvanized section, epoxy pinhole repair, slab leak rerouting, or in some cases a whole-home repipe. We use trusted supply-side components and fixtures from A.O. Smith, Rheem, Kohler, Moen, and American Standard so the repair holds up long after we leave.
Why Fresno chooses Premium Plumbing & Drain for leak detection
- Family-owned and operating in the Central Valley — we know Fresno’s soil conditions, slab construction, and older neighborhood plumbing.
- Non-invasive detection first: acoustic, thermal, and camera equipment before we cut into anything.
- Residential, commercial, and property management accounts — landlords and facility managers get one point of contact for every property in their portfolio.
- Straight pricing: we diagnose, then quote the repair before starting. No open-ended hourly surprises.
- Repair-ready trucks — most leaks are found and fixed on the same visit.
Our leak detection and repair process
- Phone intake. We ask a few targeted questions — where you see water, when the bill spiked, whether hot or cold pressure changed — to send the right technician with the right equipment.
- On-site inspection. Visual check of visible plumbing, fixtures, the water heater, and the meter to confirm active loss.
- Pressure and isolation testing. We isolate supply and drain systems to narrow the leak to a specific line or zone.
- Pinpoint detection. Acoustic sensors, thermal cameras, or sewer camera scopes depending on whether it’s a pressurized, slab, or drain leak.
- Written diagnosis and quote. You see exactly what we found, where, and what the repair options cost — before any work begins.
- Repair. Spot repair, reroute, section replacement, or repipe, using code-compliant materials.
- Verification. We re-pressurize the system, recheck the meter, and confirm the leak is gone before we pack up.
What leak detection and repair typically costs
Every leak is different, so honest pricing depends on what we find. Estimates range based on several factors: how accessible the leak is (exposed pipe under a sink versus a slab leak beneath tile), the pipe material (copper, PEX, galvanized, cast iron), whether detection alone is needed or a full repair follows, and the extent of any water damage that needs remediation. A simple under-sink supply leak is on the low end. A slab leak requiring rerouting through walls or a partial repipe sits at the higher end.
What’s always included: the diagnostic report, a written quote before work begins, code-compliant repair, cleanup, and post-repair pressure verification. What’s not included: drywall finishing, tile replacement, or flooring restoration — we can refer trusted trades for that.

Frequently asked questions
How do I know if I actually have a hidden leak?
The most common signs are an unexplained jump in your water bill, the sound of running water when nothing is on, warm spots on the floor (slab leak), mildew smell, or discolored patches on walls or ceilings. If you shut every fixture off and the meter dial still moves, water is escaping somewhere.
Will you have to tear up my floor or walls to find the leak?
Almost never as a first step. Our detection equipment is designed to locate leaks without opening anything. We only cut into a surface once we’ve pinpointed the exact spot and you’ve approved the repair.
Do you handle slab leaks in Fresno homes?
Yes. Slab leaks are common in Central Valley homes built on concrete foundations. We locate them acoustically and offer both spot repair and reroute options depending on the pipe’s overall condition.
Can you work with my insurance company?
We provide detailed written diagnostics and itemized invoices that most insurance carriers accept for water damage claims. We’re happy to document our findings for your adjuster.
Do you serve rental properties and commercial buildings?
Yes — property managers and commercial facility managers are a core part of our business. We can bill through your management company and coordinate access with tenants directly.
How fast can you get to Fresno?
We dispatch throughout the Central Valley daily and work to respond promptly to active leaks.
