Water bill jumped for no reason? Meter still spinning with every tap off? Warm spot on the floor or a stain spreading across the ceiling? Our leak detection team in Yorba Linda pinpoints hidden leaks with listening and thermal tools, then repairs them with as little damage as possible, often the same day.

Every leak hides in a different place, so we test before we open anything. Here are the leaks we track down most often, and what we do about each one.
A slab leak is a leak in a water line that runs under your concrete floor. The hot water line fails most often, because heat and hard water wear copper faster. You may feel a warm spot, hear water under the floor, or see the bill climb month after month. We find the exact spot through the concrete, then choose the repair that saves the most floor.
When the meter spins and nothing looks wet, we test the house side and the street side separately to cut the search in half fast. A notice about high use from your water provider is often the first warning.
The service line carries water from the meter to your house. A leak here can leave a soggy patch in the yard or no sign at all. We locate it, then repair the section or replace the line.
A stain below an upstairs bathroom or a drip near a balcony usually means a leaking supply line, shower valve or drain joint. Thermal imaging shows where the water is inside the wall before we cut any drywall.
A spot in the lawn that never dries, or water pooling near the meter box, can come from a buried line or a cracked sprinkler pipe. We pinpoint it so the dig stays small.
Ice maker lines, dishwasher hoses and washer valves can soak a floor overnight. We replace the failed line or valve and check the floor for trapped water.
Shops, offices, HOAs and apartment buildings in Savi Ranch and across town get the same careful testing. Learn more about our commercial plumbing service.
If the leak turns out to be the tank itself, see our water heater repair page. If it is a drain line under the slab, our sewer line repair team takes over.
We narrow the leak down step by step before we open anything. Most of the work happens with test gauges, listening gear and a thermal camera, so the only opening we make is right over the leak.
Confirm the leak
We read the meter and run a pressure test to prove water is escaping.
Split the system
We test hot and cold lines, and inside versus outside, to find which line is losing water.
Listen through the floor
An acoustic detector picks up the hiss of water leaving a pipe under concrete.
Check the heat
A thermal camera shows warm water spreading from a hot line under tile or behind drywall.
Use tracer gas if needed
For tough leaks, a safe gas pushed through the line rises at the leak point.
Mark the spot and explain the fix
You see exactly where the leak is and get your options before any repair starts.
Most leak detection visits in Yorba Linda take about 1 to 3 hours. A simple meter or service line leak can be faster. A large home, more than one leak, or a leak deep under the slab can take longer.
The repair is a separate step. A spot repair is often done the same day, while a reroute or epoxy lining can take 1 to 2 days.
A leak detection visit typically runs about $150 to $600, while water line repair or replacement in Yorba Linda typically runs about $587 to $2,400. Larger jobs like rerouting lines out of the slab can run about $1,500 to $15,000, depending on how many lines move and how far.
What moves the price:
With our upfront pricing, you get the price for each option before any work starts, so you choose the repair with the full number in front of you.
A few quick steps can limit the damage while help is on the way.
Shut off the main water valve
if water is spreading or the meter is spinning fast.
Turn off the cold supply to the water heater
if you suspect the hot line, and switch the heater to vacation or off.
Turn off the sprinkler controller
so it does not hide or add to the leak.
Take photos and note the meter reading
for your records and your insurance.
Call a plumber

Homeowners insurance often covers the water damage from a sudden slab leak and sometimes the cost to open and repair the slab, but it usually does not pay to replace the failed pipe itself. Damage from slow, long term wear is often excluded. Every policy is different, so check yours or call your agent.

Straight answers to what Yorba Linda homeowners ask us most. Still unsure? Call and ask a plumber.
Call (657) 359-9180We do both. Once we pinpoint the leak, we explain your repair options and the price for each one. Most customers choose to have us repair it during the same visit, so there is no second company to schedule and no waiting while water keeps running under the floor or inside the wall.
Not always. We test and listen first, so if the floor needs to be opened, the opening is small and right over the leak. In many homes, a reroute through the walls or attic avoids opening the slab at all. We explain the choice and the cost before anything is cut or broken.
A slab leak is urgent but not always an emergency. If water is coming up through the floor, the meter is spinning fast, or the floor feels hot, shut off the main valve and call right away. A slow leak can wait for a scheduled visit, but every day it runs adds to the bill and the risk of damage.
The repaired spot should hold, but old pipe can fail in a new spot later. That is common in homes with original copper and hard water. If you have had two or more leaks in a few years, ask us about rerouting the line or repiping, which can stop the cycle of repeat repairs.
Hot water lines fail more often because heat makes copper expand and contract every day, and hot, hard water wears the pipe wall faster. Over time this causes thin spots and pinhole leaks. If the hot line has leaked before, rerouting it above the floor is often the longest lasting fix.
A simple leak repair in a pipe, valve or fixture does not need a permit under the city's rules. Replacing a failed pipe hidden inside a wall or under a floor counts as new work, so it needs a permit and an inspection. We tell you which applies and handle the permit when one is required.
The sooner a leak is found, the less water and money it wastes. Call now, tell us what you are seeing, and we will get a plumber out to find it and fix it.
