A hidden leak inside a wall, under a floor, or behind a ceiling can run up your water bill and cause structural damage long before it's visible. We use electronic and acoustic leak detection to pinpoint the source without cutting open walls unnecessarily.

Why This Happens In Brea.

Local Cause.

Brea homes from the 1960s and 70s built with original galvanized supply lines are the most common source of hidden leaks we find. Corrosion pinholes form from the inside of the pipe with no visible warning until water starts tracking along a wall cavity or subfloor.

In Country Road's townhome community, a suspected leak can be trickier to trace since units share walls, and we factor that into how we approach acoustic tracing there compared to a detached single-family home.

Signs To Watch For.

Symptoms.

  • Unexplained increase in water bill.
  • Sound of running water with no fixture on.
  • Damp or warped flooring.
  • Musty smell with no visible source.
  • Warm spot on the floor (hot water line leak).

How we diagnose it: We use acoustic listening equipment to trace pipe sounds and electronic leak detection to pinpoint moisture location, narrowing the search to a specific section before any drywall or flooring is opened.

Options.

Repair Approaches.

🔧

Targeted access repair.

Once located, the pipe section is repaired through the smallest reasonable access point.

🔧

Reroute.

Sometimes more cost-effective than accessing a hard-to-reach leak, running a new line around the damaged section.

Common Question.

Not Sure If You Actually Have a Hidden Leak?.

A jump in your water bill with no obvious cause, or the sound of running water when every fixture is off, is the clearest early sign. We can also check your water meter: shut off every fixture in the house and watch the meter's leak indicator dial for movement, which confirms a leak is present before we come out to locate it.

What To Expect.

On The Visit.

We start by asking about your water bill history and where you've noticed dampness or sound, which narrows the search area before we bring out equipment. Acoustic and electronic tracing pinpoints the leak to a specific section, and we'll show you the readings before recommending any access point, so you understand why we're opening that particular spot.

Timing.

Emergency Call or Schedule It?.

A sudden spike in your water bill or the sound of running water with everything off is worth investigating promptly, since an undetected leak causes more damage the longer it runs. A leak you've already confirmed and contained (like a slow drip you're catching in a bucket) can usually be scheduled within a few days. Either way, call (714) 750-8637 and we'll tell you honestly which one applies.

Pricing.

What Leak Detection Typically Costs.

Every job gets a firm price before work begins. Most homeowner insurance policies only cover water damage from a sudden, accidental event, not gradual wear, ask your insurer about your specific policy.

Leak detection service$350-$650
Includes acoustic/electronic tracing to locate the source.
Repair (after location confirmed)$300-$900
Depends on access and pipe material.

What affects your price:

  • How large an area needs to be scanned to locate the leak.
  • Whether the leak is in an accessible wall/floor or a harder-to-reach location.
  • Whether repair is bundled with the detection service.
  • Same-day emergency service versus scheduled diagnostic.

FAQs.

How do you find a leak without cutting into walls?
Acoustic equipment picks up the sound of water escaping under pressure, and electronic moisture detection narrows the location further, so we typically only need a small access point rather than opening an entire wall.
Can a hidden leak cause mold?
Yes, if it goes undetected long enough. If you already have visible mold or water-damaged drywall, that's a restoration job in addition to the plumbing repair, see our note on water damage restoration.
How accurate is electronic leak detection?
Combined with acoustic tracing, it typically narrows the leak location to a small, specific area, meaning far less exploratory opening of walls or flooring than guessing based on symptoms alone.

The sooner a hidden leak is found, the less structural damage it causes. If your water bill has jumped with no clear explanation, that's worth a call before it gets worse. A leak specifically under a concrete foundation needs a different diagnostic approach, covered on our slab leak detection and repair page. Once a leak is confirmed, our repiping page covers what to do if it turns out to be one of several failing sections. We get this call often from Brea Hills homes with elevation-related pressure issues.

Parts and labor on completed leak detection work are covered under our standard workmanship warranty, and every job gets a firm, written price before we start, not an estimate that changes once the work is underway.

All repairs are performed to the standards of the California Plumbing Code (based on the Uniform Plumbing Code, UPC).
