Our Leak Detection Process

Residential Leak Detectors

Step 1 – Initial Consultation & Property Assessment

Our technician begins by discussing the symptoms you've noticed, such as a high water bill, low water pressure, warm spots on the floor, or the sound of running water. We then perform a visual assessment of your home's plumbing system and surrounding property.

Step 2 – Water Meter & Plumbing System Testing

We inspect your water meter for continuous movement and perform diagnostic tests on the home's plumbing system to determine whether an active leak is present. Pressure testing may also be performed to verify the integrity of the pressurized water system.

Step 3 – Advanced Leak Detection

Using state-of-the-art technology, we accurately locate hidden leaks without unnecessary demolition. Our equipment includes: Acoustic leak detection equipment Thermal imaging cameras Helium tracer gas Electronic pipe locating equipment Professional moisture meters

Step 4 – Precise Leak Location

Once testing is complete, we pinpoint the exact location of the leak, whether it's beneath a concrete slab, underground, inside a wall, in the main water line, or within the irrigation system. We clearly mark the affected area to minimize repair costs.

Step 5 – Detailed Findings & Repair Recommendations

After identifying the source of the leak, we explain our findings in detail and provide a comprehensive report along with the most effective repair options. If no leak is found, we'll discuss other potential causes of high water usage or plumbing concerns.

Step 6 – Professional Repair & Ongoing Protection

If repairs are needed, our experienced technicians can complete many plumbing repairs, including slab leaks, main water line repairs, pipe reroutes, and irrigation leak repairs. We also recommend smart leak protection solutions, such as the Flo by Moen Smart Water Monitor & Shutoff, to provide 24/7 monitoring, instant leak alerts, automatic water shutoff, and long-term protection against costly water damage.

Frequently Asked Questions

How do I know if I have a hidden water leak?

Common signs include a high water bill, the sound of running water when nothing is on, warm spots on the floor, wet drywall, mold growth, or a water meter that continues moving after all fixtures are turned off.

Can you find a leak without cutting into my walls or floors?

Yes. Our advanced acoustic listening equipment, thermal imaging cameras, helium tracer gas, and electronic pipe locating technology allow us to locate most leaks without unnecessary damage to your home.

What is a slab leak?

A slab leak is a leak in a water pipe located beneath your home's concrete foundation. Early detection helps prevent structural damage, mold growth, and costly repairs.

What causes a high water bill?

A high water bill can result from hidden plumbing leaks, irrigation leaks, leaking toilets, slab leaks, underground main water line leaks, or continuously running fixtures. We can determine the source through professional leak detection.

How long does a residential leak detection service take?

Most residential leak detection appointments take between one and three hours, depending on the size of the property and the complexity of the plumbing system.

Do you repair leaks after finding them?

Yes. Once the leak is accurately located, we explain your repair options and can often provide repair services, including main water line repairs, slab leak repairs, and plumbing reroutes.
