Leak Detection in Whittier, CA
Water leaks rarely announce themselves. Call (562) 439-3888 and we connect you with an independent Whittier-area provider who can find the leak without tearing the house apart.
Slab leaks, hidden wall and floor leaks, pool and spa leaks, yard and irrigation leaks, sewer line problems and high-water-bill investigations all start with the same call.
Leak Fix Pros is a referral service. The providers we connect you with are independent businesses that perform the work and set their own prices.
Short answer: To find a hidden leak in Whittier, first check your water meter with all water off. If it still moves, you have a leak. Then call to reach a provider who locates it with listening equipment, thermal imaging or tracer gas, so only the leaking spot needs to be repaired.
What happens when you call
Leak Fix Pros is a phone referral service for leak detection in Whittier, CA. We do not send our own crews. The call is the service: a short conversation, then a connection to an independent provider.
- You call (562) 439-3888
Tell us what you see: a high bill, a moving meter, a damp wall, a warm floor, a wet yard. A rough description is enough. - We match the problem
Slab, pool, sewer, yard line or hidden wall leak? We connect you with a provider who handles that kind of problem in your part of Whittier, depending on availability. - The provider takes over
They ask a few questions, explain what they will test, and give you their price and timing. Pricing, scheduling, licensing and guarantees are theirs to state. - You decide
You are not obliged to book. Ask about the method, the report and any repair quote before you agree.

Signs you may have a leak
A leak does not always mean a puddle. Many leaks show up first as a number on a bill or a quiet change in the house:
- A water meter that keeps moving when every tap and appliance is off.
- A water bill that rises with no change in household or irrigation use.
- Warm patches on the floor, or the sound of running water in a quiet house.
- Stains, bubbling paint, swollen baseboards or a musty smell. See hidden wall and floor leaks.
- A pool or spa that loses more water than evaporation explains. See pool and spa leaks.
- Wet, sunken or unusually green ground in the yard. See irrigation and yard leaks.
- Slow drains, gurgling or sewer odor. See sewer video inspection.

The fastest first test is the meter check: shut off all water, record the meter reading, wait about two hours without using any water, and read it again. The U.S. EPA recommends it, and a changed reading means water is going somewhere. Our guide to high water bill leak detection covers the meter, toilet dye and fixture tests in detail.
How professionals find a leak without demolition
Good leak detection is measurement first, repair second. Providers combine several tools: moisture meters to map damp materials, listening devices to hear water escaping under pressure, thermal cameras to read surface temperature, pressure tests to isolate lines, and tracer gas to confirm a hard-to-find leak. The detail is on the leak detection methods page, including which tool suits which problem.
For a floor-level problem such as a warm spot or a running meter, a slab leak detection visit is the usual path. When the leak is located, the provider will explain the repair choices, from a small spot repair to rerouting or trenchless pipe lining.
If the leak has already caused damage, ask for a written report. Insurance leak detection reports document the cause, the location and the method, which can help with a claim. Whether a claim is paid is a matter for your policy.
Whittier neighborhoods and areas we serve
Different parts of Whittier have different housing, lot sizes and plumbing ages, so a leak in one area is not always a leak in another. These pages explain what is distinct about each:
- Uptown WhittierHistoric shopping district: restaurants, shops, lofts and older buildings.
- Hadley-Greenleaf Historic DistrictA locally designated historic district with 190+ properties.
- College HillsWhittier's first planned hillside development, subdivided in 1923.
- East WhittierLarger homes and yards east of the 605 Freeway.
- Friendly HillsHillside neighborhood of larger custom homes with views.
- South WhittierA large, densely settled community just south of the city.
- Mar Vista HeightsA neighborhood of mid-century ranches, prewar colonials and larger lots.
Beyond the pages above, we take calls from across Whittier and nearby communities, including The Groves and Leffingwell. If your address is not listed, call and ask.
The Hadley-Greenleaf Historic District and College Hills are locally designated historic districts with older homes. Uptown Whittier adds shops, restaurants and lofts to the picture, while East Whittier, Friendly Hills and Mar Vista Heights lean toward larger lots with irrigation and pools to rule out. South Whittier has a large mix of owners and renters.
Who you will be connected with
The providers we connect you with are independent local businesses. Depending on availability, you may be connected with a company that has years of industry experience, uses electronic leak location equipment and prepares written reports. Credentials differ from provider to provider, and none of them are ours.
Before you hire, ask the provider directly:
- Which methods will you use for my situation, and how will you confirm the leak location?
- What does the price include? Is detection billed separately from repair, and is it credited?
- Will I receive photos or a written report?
- What California contractor license do you hold for the repair work you are proposing? (You can look up any license number on the Contractors State License Board site at cslb.ca.gov.)
- What guarantee, if any, do you provide, and is it in writing?
See our about page for how the referral service works and how it differs from the providers.
What leak detection costs
Providers set their own prices, so we do not publish a figure. What moves a quote: the type of leak, the number of lines to test, how deep or hard to reach the pipe is, what lies above it, and whether you need a report or a repair afterward. A pool inspection, a slab leak search and a sewer camera run are priced differently, and detection is often priced apart from repair. The best protection is to ask what is included before you agree to the visit.
Frequently asked questions
What is a leak detection service in Whittier, CA?
A leak detection service finds where water is escaping from plumbing, a pool or a buried line, using meter tests, listening equipment, thermal imaging, pressure tests and tracer gas, so repairs can target the exact spot. Leak Fix Pros is a phone referral service that connects you with independent providers who do this work.
How do I know if I have a water leak in my home?
Warning signs include a water meter that moves when everything is off, an unexplained rise in the water bill, the sound of running water, warm spots on the floor, damp walls or ceilings, a musty smell and low pressure. The meter test is the quickest check.
What should I do first when I find a leak?
Shut off the water at the main valve if you can reach it safely, turn off electricity near standing water if it is safe to do so, take photos for your records, and call for help. Do not touch electrical equipment in standing water.
How much does leak detection cost in Whittier?
Independent providers set their own prices, and cost depends on the type of leak, the size of the property, how hard the pipe is to reach and whether you need a written report. Ask each provider what is included and whether detection is credited toward repair.
Is Leak Fix Pros a plumbing company?
No. Leak Fix Pros is a referral service. When you call, we connect you with an independent local provider. The provider, not us, performs the work, sets the price, and holds any licenses, insurance and guarantees.
Can leaks be found without breaking floors, walls or concrete?
In most cases the leak location is found from the surface using non-invasive tools. A small opening is made only where a repair requires it.
What should I do if there is a gas leak?
Leave the building right away, then call SoCalGas at 1-800-427-2200 from a safe place and call 911 if there is any danger. Do not use a leak detection service as a substitute for emergency gas response.
Who is responsible for a leak outside the water meter?
In general the utility is responsible up to the meter and the property owner for the line on the house side, but this varies. Confirm with your water utility.
If you smell gas
Leave the building immediately. From a safe place, call SoCalGas at 1-800-427-2200, and call 911 if there is any danger. Do not turn lights or appliances on or off, and do not call a leak detection service first.
