When a slab leak is an emergency
Emergency slab leak repair in Dixon, CA applies when water is coming up through the floor, a hot spot has appeared in a room or the meter runs while everything is off. A slab leak is a pressurized pipe leaking under or inside the concrete foundation, so it keeps running until it is shut off.
Our line is answered 24/7. While you wait, shut off the main water valve to stop the flow, and turn off the water heater if hot water is involved. Move rugs and furniture off wet floors, and keep power off in any room where water reached outlets.
Slab leak signs, paraphrased from what callers describe
Callers describe slab leaks in a handful of ways. Any two of these together are a good reason to call.
A warm or hot patch on the floor
A hot water line under the slab is leaking.
Water coming up near baseboards or floor seams
Pressure is pushing water along the easiest path to the surface.
The sound of running water in a quiet house
Water is moving where no fixture is open.
A meter that keeps turning with everything off
A line is leaking somewhere past the meter.
Damp carpet or a musty smell
Moisture is wicking up from below.
Not every one of these means a slab leak. A leak detection visit confirms where the water is really coming from.
Dixon's rules for pipe under a slab
Source type: City of Dixon Building Division water line handout.The City of Dixon's water line repair and replacement handout sets the ground rules for supply pipe near and under a building. Below the building, the pipe is expected to be Type L copper, and copper under a slab is to have no joints.
The handout also says PVC and polyethylene are not allowed for water supply, calls for tracer wire on buried plastic, and sets 12 inches of cover. A pressure test at working pressure for 15 minutes is part of the check. If city connections or street work are involved, an encroachment permit applies.
The practical point for a slab leak is that a repair or reroute has to meet those rules. That affects the materials used, the number of joints in the finished work and whether the job needs a permit and inspection.
A slab repair follows the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC). The City of Dixon's water line handout cites section 604.1 and calls for a 15 minute pressure test at working pressure after the work.
Repair paths for a slab leak
There are three common ways to fix a slab leak. The right one depends on the pipe, the location of the leak and how many leaks there have been.
| Path | What it involves | Best when | Trade-off |
|---|---|---|---|
| Spot repair through the slab | Locate the leak, cut and open the concrete, replace the failed section | A single leak in an accessible spot | Concrete work and flooring replacement. |
| Reroute overhead | Abandon the leaking line under the slab and run new pipe through walls or attic | Repeat leaks or a hard-to-reach line | More pipe work, less cutting of the slab. |
| Repipe the system | Replace the supply lines throughout the house | Several leaks or failing old pipe | Largest job, but the longest-lasting fix. |
If the pipe is failing in several places, the repiping page covers what a whole-house job looks like.
What to do before we arrive at a slab leak
A leak under the floor is quiet, but the water has to go somewhere. These steps protect the house and the people in it.
- Close the main water valve to stop the flow.
- Do not touch outlets, cords or appliances standing in water.
- Switch off the breaker for any room with standing water if you can reach it dry.
- Keep children and pets off wet or warm floors.
- Photograph damage before you move things.
- Do not run taps while you wait.
Warm spot or water on the floor?
Shut off the main valve and call the 24/7 line. A same-day appointment is offered when available.

Pinpoint the spot
Electronic listening and thermal imaging narrow the location to a small area.
Choose the repair path
You hear the options and the price before anything is cut.
Repair and test
The pipe is repaired or rerouted, pressure tested, and the floor is restored or handed off to a flooring contractor.

Slab leak jobs vary a great deal, so price depends on a few real factors and a plan agreed before work.

Slab leak questions from Dixon homeowners
Yes. The line is answered 24/7. Shut off the main water valve, then call and ask for a same-day appointment when available.
Common signs are a warm spot on the floor, the sound of water in a quiet house, damp flooring and a meter that runs with everything off. A plumber confirms with a pressure test and electronic listening.
No. A reroute through the walls or attic avoids cutting the slab. Which path fits depends on the leak location, the pipe and how many leaks there have been.
Water line replacement work generally does. The City of Dixon's handout lists pipe, pressure test and cover rules, and the Building Division can confirm what applies to your job.
A long-running leak can soften soil under the slab and cause settling in some cases. It is one more reason to act when the signs appear rather than waiting.
