Slab Leak Detection in Lacey, WA
A pipe is leaking under your concrete floor. We find the exact spot through the slab, so the repair is a small patch instead of a broken up room.
Clues That Point Under the Slab
A slab leak rarely announces itself with a puddle. Look for these instead.
- A warm or hot spot on the floor. Walk barefoot. A hot water line leaking under the slab heats the concrete above it.
- The sound of running water with every faucet off.
- Cracks in tile or grout that were not there before.
- Flooring that lifts, cups or buckles, especially laminate and hardwood.
- Damp or discolored carpet with no spill to explain it.
- A water heater that runs constantly. It is refilling and reheating water lost to a hot line leak.
- A water bill that keeps climbing.
- Mildew smell near baseboards on the ground floor.
One clue alone may be something else. Two or three together usually means a slab leak.
Which Lacey Buildings Sit on Slabs?
Many Lacey homes are built over crawl spaces, but slab foundations are common too. You will find them under many garages and ground floor units of apartment buildings, in a number of townhomes and single story homes, in shops and offices, and in some newer construction around the city.
If your floors are concrete under the carpet, tile or wood, and there is no crawl space hatch, you are likely on a slab. If you have a crawl space, see our crawl space leak detection page instead.
Why Slab Leaks Happen
- Pipe movement. Pipes expand and contract with hot water. Where they rub against concrete or gravel, they wear thin over years.
- Poor installation. A kinked line or bad joint poured into concrete can fail long after the house is finished.
- Soil shifting. Wet winters and dry summers change soil moisture, and small shifts put stress on pipes.
- Water chemistry. Water from wells and aquifers, like Lacey's supply, can carry minerals that affect some pipe materials over time.
- Age. Older copper and galvanized lines under a slab eventually give out.
How We Pinpoint a Slab Leak
- Confirm the leak.
Meter and pressure tests tell us water is being lost under pressure.
- Split hot from cold.
We test each side separately. A hot side leak points us to warm spots and heat mapping. A cold side leak needs different tools.
- Trace the pipe route.
We map where the lines run under the slab so we know where to listen.
- Listen through the concrete.
Sensitive ground microphones pick up the hiss of water escaping the pipe. We work across the floor until the sound peaks.
- Confirm with thermal imaging.
Heat patterns on the floor surface back up the acoustic reading on hot lines.
- Mark the spot.
We mark the exact location on the floor, usually within a small area.
You get the location, photos and notes for your plumber and insurance.
After We Find It
Knowing the exact spot gives you real choices:
- Spot repair. A small opening in the slab to fix that one section.
- Reroute. Running a new line through walls or the attic and abandoning the leaking section. Often chosen when the old line has more weak spots.
- Repipe. Replacing the whole system if testing shows the pipes are failing throughout.
We explain which fits what we found.
Do This Now
- If you hear running water or feel a hot spot, turn off the water heater's cold water supply valve at the top of the tank. That stops a hot line leak from running.
- If the leak is on the cold side, shut off the main valve when you are not using water.
- Pull back rugs and move furniture off wet flooring.
- Take photos of cracks, warm spots and damage.
Frequently Asked Questions
Do you have to break up my floor to find a slab leak?
No. We locate it from above the slab. The only opening is for the repair, and it is small because it is in the right place.
How accurate is slab leak detection?
With acoustic and thermal tools working together, we usually narrow the leak to a small area of the floor.
Is a slab leak an emergency?
If water is surfacing, flooring is lifting or the bill is spiking, act quickly. A slab leak can soften soil under the foundation and feed mold under flooring.
Does insurance cover slab leaks?
Many policies cover the damage and sometimes the cost to access the pipe, but often not the pipe repair itself. Check your policy and keep our report.
Can a slab leak happen in a newer home?
Yes. Faulty fittings or lines damaged during construction can fail in the first years.
How much does slab leak detection cost?
It usually costs more than a simple leak check because of the extra testing. See our cost guide.
