Leak Detection in Novato, CA

Non-invasive water leak detection across 4 zip codes in Novato. Same-day appointments available.

Leak detection used to mean opening walls and hoping the first cut found something. Today's approach is the reverse: prove the location first, open things up only when the evidence says so. Acoustic sensors pick up the hiss of pressurized water escaping through a pinhole; thermal cameras reveal the cool signatures of evaporating moisture behind drywall; tracer gas and pressure testing confirm which line is compromised.

Each Novato job gets the combination that fits the symptoms, not a one-size-fits-all sweep. A warm spot on the floor points one way; a meter that spins with everything off points another. For Novato homeowners across the 4 ZIP codes we cover, the goal is identical: narrow the search to inches before a single tile is lifted, so the repair that follows is smaller, quicker, and over sooner.

Signs You May Need Leak Detection in Novato

Not every leak happens indoors. Between irrigation systems, pool plumbing, and main service lines, Novato properties have plenty of buried water lines, and outdoor leaks can waste enormous volumes before anyone notices, because there's no wall to stain and no floor to warp. Outdoor warning signs include:

  • A pool losing water faster than evaporation can explain
  • Soggy or spongy lawn areas that never seem to dry out
  • One patch of grass growing noticeably faster and greener than the rest
  • Water pooling near the foundation or along walkways
  • The meter spinning with the house shut off but irrigation valves open
  • Hissing or running water audible near hose bibs or valve boxes
  • Settling or cracking in driveways and patios, from soil washing away underneath

Outdoor leaks get their own toolkit, line tracing, pressure testing, and acoustic equipment tuned for soil. If your Novato yard is telling this kind of story, a targeted outdoor inspection will sort irrigation trouble from a supply-line break without digging up the whole property.

How We Find Leaks in Novato

Endoscopic cameras, slim, flexible borescopes slipped through a tiny opening, let a technician see inside wall cavities, under tubs, and behind fixtures without removing anything larger than a switch plate. When acoustic or thermal readings suggest a general area, a camera confirms what's actually happening inside: the corroded fitting, the split joint, the slow drip caught in the act. Seeing the leak removes the last shred of doubt before repair work begins.

No single instrument covers every scenario, which is why a proper visit layers methods. Sound finds pressurized breaks; thermal maps moisture; pressure testing isolates the line; cameras confirm visually. The technician's real skill is choosing the sequence, starting broad and inexpensive, then deploying the precise tools only where the evidence points.

Across Novato, that layered method is what separates genuine leak detection from an expensive guess. When every step is confirmed by an instrument, the mark on the floor is a promise, and the repair that follows is exactly as big as it needs to be, and no bigger.

What a Leak Detection Visit Looks Like

Knowing what happens during a visit takes the mystery out of it. Here is how a typical leak detection appointment unfolds:

  1. The call: you describe the symptoms, bill spike, sounds, stains, and we schedule, often for the same day.
  2. Meter check on arrival: the technician verifies water is actually escaping by watching the meter with fixtures off, establishing there's a real leak to find.
  3. Systematic sweep: acoustic listening, thermal imaging, and moisture readings work across the suspected area, narrowing from rooms to square feet to inches.
  4. Pinpoint and mark: the confirmed location is marked directly on the floor or wall, so there's no ambiguity later.
  5. Findings and next steps: you get a clear explanation of what was found and where, plus guidance on getting the repair itself scheduled.

Most visits wrap up in a single appointment, and because the methods are non-invasive, your home looks the same when we leave as when we arrived, minus the mystery of where the water was going.

Frequently Asked Questions

Do you work on commercial properties, or just homes?Both. The instruments and methods are the same whether the leak sits under a home's slab or a commercial building's, acoustic listening, thermal imaging, pressure testing, and line tracing all scale to larger properties. Offices, retail spaces, restaurants, and multi-unit buildings are all routine work for us. Commercial visits can take longer and are sometimes scheduled around business hours, so mention the property type when you call.
What happens after you find the leak? Do you fix it?We specialize in detection, locating the leak precisely is the entire service. Once the break is confirmed and marked, you receive clear written findings to hand to your plumber, who handles the actual repair. This separation is intentional: because we don't sell repairs, our diagnosis has no upsell baked into it. If you don't have a plumber yet, we're happy to suggest what to look for in one, but the choice stays entirely yours.
How should I prepare for the visit?Three quick things. First, clear access to the water heater, the main water shutoff, and any area showing symptoms, move stored items away from those spots. Second, write down what you've noticed and when: bill changes, sounds, smells, stains, and their timeline. That history aims the instruments faster. Third, make sure an adult is home who can grant access to every room, the attic, or the crawlspace. Ten minutes of preparation typically shortens the visit noticeably.
How do I know if it's a plumbing leak, an irrigation leak, or my pool?You usually can't tell from symptoms alone, a wet yard patch could be any of the three, which is why guessing gets expensive. The visit starts by separating the systems: the main shutoff test tells us whether the loss is inside the house or outside it, then irrigation zones are isolated one at a time, and pool equipment gets its own bucket-test and pressure check. Each system has a distinct diagnostic path, and ruling them out in the right order is most of the skill. By the end of the visit you won't just know there's a leak, you'll know which system it's in and exactly where.
Do I get a written report after the visit?Yes. Every visit ends with clear written findings: what was tested, what the instruments showed, the confirmed location of the leak (marked and photographed on site), and which system it's on. That report is yours to hand to your plumber, your property manager, or your insurer, it's written to be forwarded, not filed away. Because we don't perform repairs, the report has no upsell in it; it's simply what the evidence showed at your Novato property.
