A warm spot on a tile or wood floor
Before cleanup moves forward, heated water escaping under the concrete warms the slab above it. In simple terms, walk the floor barefoot and you can regularly find the area within a foot or two.

Signs to look for
When to call us for slab leak damage
In simple terms, if you notice any of these problems, call us before water has more time to spread into nearby materials.
You hear water running with everything turned off
In simple terms, stand in a quiet room at night and listen at floor level. For your property, a steady hiss or rush with every fixture closed is water leaving the system.
The water heater cycles constantly
For your property, a leak on the hot water line or a recirculation line pulls heated water out around the clock.
New cracks in the slab or in floor tile
To keep the next step clear, water changes the soil under a slab, and movement shows up as cracked tile or a new line in the concrete.
Baseboards and door casings are damp along one wall
For your property, water in the slab wicks up into the bottom of the drywall and the trim.
Dark or damp grout in a line across the floor
Before cleanup moves forward, grout is the most permeable part of a tile floor, so moisture appears there first.
What happens
How we handle slab leak damage
Our water-damage team adjusts the work to where the water reached, where the water went, and the materials that can be saved.
Confirming the water is coming from below
Before cleanup moves forward, we rule out the roof, the walls and every fixture in the area first.
Locating the leak so nobody cuts on a guess
To keep the next step clear, meter readings, surface temperature differences and a thermal imaging camera narrow the area before any concrete is considered.
Marking the affected slab area and its edges
Before cleanup moves forward, the wet boundary gets drawn on the floor and recorded in a map.
Extraction of the water that came up through the slab
To keep the next step clear, standing water, wet carpet and pad, and water sitting under a floating floor all get removed. In simple terms, carpet pad in the water-damaged area comes out.
Flooring removal only where it has to come up
Before cleanup moves forward, tile with sound thinset and grout regularly stays down. To keep the next step clear, laminate over a wet slab and glued wood generally have to be removed for the slab to dry.
Wall base and cavity drying where water wicked up
Before cleanup moves forward, drywall pulls moisture up from a wet slab by wicking, so the bottom band of the wall gets metered and dried.

What to expect
What to expect from our water-damage team
Here is how we generally handle slab leak damage near Wisconsin.
-
1
Share what is warm, wet or louder than it should be
Before cleanup moves forward, those three symptoms point almost anywhere else in a building except under the floor.
Your call -
2
Shut the water heater down safely to test the hot side
Before cleanup moves forward, turn the water heater off first, meaning the gas control to pilot or off, or the breaker off.
+10 minutes -
3
Ruling out everything above the slab first
To keep the next step clear, on arrival the lead checks fixtures, walls and the ceiling in the water-damaged area. Before cleanup moves forward, that elimination is what makes the slab diagnosis credible.
On arrival -
4
The water-damaged area mapped and marked on the floor
For your property, a moisture meter, surface temperature differences and the damp line at the flooring edge set the boundary, and it gets drawn and photographed.
First hours on site -
5
Flooring opened where it must be, water extracted
Before cleanup moves forward, wet carpet and pad, swollen laminate and failed adhesive come up in the marked area.
Same day -
6
Reroute or open the slab, and what each means for drying
Before cleanup moves forward, your plumber makes that call, and we explain the drying consequence of both.
Plumber's day -
7
Equipment set on the slab after the repair
For your property, air movers over the concrete, Professional dehumidifiers taking moisture out of the air, and negative pressure under floating assemblies where the system allows it.
After the repair
Understanding the cost
What can affect the price
We explain in plain language the step-by-step cleanup plan and price before you approve the job. These examples show what may change the estimate.
| Common situation | What the estimate may include | Typical range |
|---|---|---|
| Leak location survey with meter readings and thermal imaging | To keep the next step clear, national estimate. Before cleanup moves forward, the right first step before anyone considers opening concrete. | $250 to $600 |
| Slab leak drying, one room, flooring stays down | To keep the next step clear, national estimate. For your property, extraction, slab drying and four to six days of equipment with daily readings. | $1,200 to $3,500 |
| Slab leak with flooring removal and slab drying across two rooms | To keep the next step clear, national estimate. Before cleanup moves forward, flooring and pad removal, wall base drying and extended slab drying. | $3,000 to $8,000 |
| Slab leak cleanup where cabinetry and wall bases are involved | To keep the next step clear, national estimate. For your property, toe kick voids, wall bases and trim in addition to the slab itself. | $1,500 to $5,000 |
| Slab drying priced by affected area, clean water | National estimate. Measured water-damaged area of the slab rather than the whole room. | $3 to $7 per square foot |
| Slab moisture documentation before new flooring is installed | To keep the next step clear, national estimate. | $150 to $400 |
| Your plumber's slab leak repair, reroute or open the slab | To keep the next step clear, national estimate for your plumber's work plan, listed so the total is not a surprise. | $1,000 to $6,000 |
How long the leak ran before it was found
Slab leaks are generally found late, and every week widens the saturated area under the floor. Duration also decides how much flooring is salvageable.Hot side or cold side
A hot water line leak adds heat and humidity to the space and shows itself sooner as a warm spot.Flooring type over the slab
Tile with sound thinset regularly stays down. Glued hardwood, laminate and carpet with pad generally come up, and removal is labor plus disposal.How much flooring has to be removed
In simple terms, removal is priced by area, and the marked wet boundary is what keeps it honest.Whether wall bases wicked moisture up
To keep the next step clear, if the bottom band of drywall reads wet, trim comes off and that band gets dried or removed.Concrete drying days
Before cleanup moves forward, air movers run roughly $25 to $40 per unit per day and Professional dehumidifiers roughly $70 to $110 per unit per day.
Why timing matters
What can happen when the area stays wet
Water might keep moving into nearby materials even when the surface looks dry.
A slab leak does not drain, it saturates
In simple terms, water under concrete has nowhere to go, so it soaks the soil and the slab continuously.
Concrete keeps releasing water after the leak stops
In simple terms, a saturated slab feeds moisture into the room for days once the pipe is fixed.
New flooring over a wet slab fails, and the warranty goes with it
In simple terms, adhesives release, laminate cores swell and wood cups when the slab beneath is still giving up moisture.
The soil under the slab can wash out or swell
To keep the next step clear, continuous water either carries fine soil away or expands clay soils.

Begin with the short explanation. Open a card if you want a little more detail.
What is happening inside the property
In slab on grade construction, water supply lines are commonly run inside or beneath the concrete, historically in soft copper tubing.
Read the explanation
It helps to know what is actually down there. In slab on grade construction, water supply lines are commonly run inside or beneath the concrete, historically in soft copper tubing.
How the next step is decided
To keep the next step clear, a reroute abandons the failed section and runs new pipe overhead or through walls.
Read the explanation
To keep the next step clear, reroute or open the slab is your plumber's decision, and we explain what each one means for our half of the job.
What may change the work
Before cleanup moves forward, concrete holds water in a fine pore structure and gives it back gradually.
Read the explanation
For your property, drying concrete is a slower science than drying drywall and it needs to be measured rather than assumed.

Questions about slab leak damage
What is a slab leak?
In simple terms, it is a leak in a water line that runs inside or beneath the concrete floor of a slab on grade building.
How do I know if I have a slab leak?
To keep the next step clear, look for a warm spot on the floor, or the sound of running water with everything off.
Why is one spot on my floor warm?
To keep the next step clear, because hot water is escaping under the concrete and heating the slab above it.
Do you find the slab leak or does a plumber?
To keep the next step clear, we locate the water-damaged area and narrow the leak location using moisture readings, surface temperature and the pattern of the wet boundary.
Does the slab have to be jackhammered?
To keep the next step clear, not always. To keep the next step clear, many plumbers prefer a reroute, which abandons the failed run and routes new pipe through walls or the attic.
What is a reroute?
In simple terms, it is new pipe run above the slab to replace the failed section underneath it.
Can concrete be dried, or does it have to be replaced?
To keep the next step clear, concrete dries. In simple terms, it just does it slowly, because water sits in the pore structure and comes out over days rather than hours.
