  • Pool and irrigation line leaks
Common Warning Signs

Signs You Need Leak Detection in Redwood City

Hidden leaks rarely announce themselves directly. They usually show up as a side effect somewhere else first.

  • Your water bill jumped with no obvious change in usage
  • You hear running water when every fixture is off
  • A warm patch appears on an otherwise cool slab floor
  • Damp spots, bubbling paint, or a musty smell without a visible source
  • Your water meter keeps moving during a two hour no use test

Once a leak is pinpointed, the fix itself may fall under pipe repair if it is a supply line, or sewer repair if it turns out to be a broken lateral rather than a fresh water leak. We will tell you which applies once the leak is located.

How It Works

Our Leak Detection Process

1. Non invasive detection. We use acoustic listening equipment and thermal imaging to narrow down the leak's location without opening up walls or floors first.

2. Pinpoint and quote. Once the leak is isolated to a specific area, you get one flat rate quote for the repair.

3. Repair or refer. If the fix is straightforward, we complete it on the spot. If it requires a different specialty, such as sewer repair, we will say so honestly.

Slab leaks are especially common in homes with copper supply lines run under the foundation, which describes a large share of Redwood City's older housing stock. Catching one early with proper detection tools avoids the far more expensive alternative of breaking into a slab to search for it.

What We Handle

Leak Detection Services We Offer

Slab Leak Detection

Acoustic and thermal detection to pinpoint leaks under a concrete foundation without breaking up the slab to search for it.

  • Acoustic listening equipment traces the sound of escaping water
  • Thermal imaging spots temperature changes at the slab surface
  • Narrows the leak to a specific, small work area
  • Avoids unnecessary demolition across the whole floor

Hidden Pipe Leak Detection

Locating leaks inside walls and ceilings without unnecessary demolition, so repairs stay small and targeted.

  • Finds leaks behind drywall, tile, and cabinetry
  • Distinguishes a plumbing leak from condensation or roof intrusion
  • Confirms the exact wall stud bay or ceiling joist bay affected
  • Hands off cleanly to repair once the leak is located

Pool and Irrigation Leak Detection

Finding leaks in outdoor water lines, pools, and irrigation systems that show up as unexplained water loss.

  • Pressure tests pool plumbing separate from the pool shell
  • Traces irrigation line leaks along buried supply runs
  • Identifies valve and backflow assembly leaks outdoors
  • Useful when a high bill has no obvious indoor cause
Repair Basics

Professional Detection vs. Guess and Dig

Without the right equipment, finding a hidden leak usually means trial and error. Here is the difference.

Guess and Dig

  • Relies on opening walls or slabs based on best guess
  • Can miss the actual leak location entirely
  • Creates repair costs beyond the plumbing itself, like drywall or flooring
  • Often requires multiple attempts to find the source

Professional Detection

  • Acoustic and thermal tools narrow the location before any digging
  • Confirms the leak's exact position, not just its general area
  • Minimizes the size of any necessary opening for repair
  • One flat rate quote once the leak is actually confirmed

How Much Leaks Actually Cost

The EPA's WaterSense Fix a Leak Week program estimates that household leaks waste nearly one trillion gallons of water nationwide every year, and that ten percent of homes have a leak wasting 90 gallons or more per day.

Regional Water Conservation Resources

The Bay Area Water Supply and Conservation Agency serves Redwood City and neighboring communities with water conservation programs, including guidance specifically focused on finding and fixing household leaks.

Common Questions

Frequently Asked Questions

Who offers reliable leak detection in Redwood City?

Handy Bay Plumbing uses acoustic and thermal equipment, with flat rate pricing and same day availability for most calls.

How much does leak detection cost in Redwood City?

Cost depends on how difficult the leak is to locate and what type of repair follows. We quote leak detection separately from the repair itself, so you know both numbers before deciding.

How do I know if I have a hidden leak?

A sudden jump in your water bill, the sound of running water with everything off, or a warm spot on a slab floor are the most common signs. A simple check is to read your water meter, wait two hours with no water use, and read it again.

Can you find a leak without breaking into my wall or floor?

In most cases, yes. Acoustic and thermal detection can narrow the leak's location closely enough that only a small, targeted opening is needed for the repair.
