Signs to look for
When to call us for slab leak damage
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
Stand in a quiet room at night and listen at floor level. A steady hiss or rush with every fixture closed is water leaving the system.
The water heater cycles constantly
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
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
Water in the slab wicks up into the bottom of the drywall and the trim. Damp trim with a dry ceiling almost always means the water came from below.
Dark or damp grout in a line across the floor
Grout is the most permeable part of a tile floor, so moisture appears there first. A line rather than a patch tends to follow the pipe run.
What happens
How we handle slab leak damage
Our crew adjusts the work to which areas and materials are wet, the distance the water traveled, and what materials can be saved.
Confirming the water is coming from below
We rule out the roof, the walls and every fixture in the area first. A slab leak diagnosis is only sound once the easy sources are eliminated.
Locating the leak so nobody cuts on a guess
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
The wet boundary gets drawn on the floor and recorded in a map. That marking is what keeps flooring removal from becoming guesswork.
Extraction of the water that came up through the slab
Standing water, wet carpet and pad, and water sitting under a floating floor all get removed. Carpet pad in the wet area comes out.
Flooring removal only where it has to come up
Tile with sound thinset and grout frequently stays down. Laminate over a wet slab and glued wood typically have to be removed for the slab to dry.
Wall base and cavity drying where water wicked up
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 crew
Here is how we typically handle slab leak damage near Buffalo, SD.
-
1
Let us know what is warm, wet or louder than it should be
Those three symptoms point almost anywhere else in a building except under the floor. Together they point down, and that changes what we bring.
Your call -
2
Shut the water heater down safely to test the hot side
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
On arrival the lead checks fixtures, walls and the ceiling in the wet area. That elimination is what makes the slab diagnosis credible.
On arrival -
4
The wet area mapped and marked on the floor
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
Wet carpet and pad, swollen laminate and failed adhesive come up in the marked area. Standing water and water trapped under floating floors get removed.
Same day -
6
Reroute or open the slab, and what each means for drying
Your plumber makes that call, and we explain the drying consequence of both. A reroute leaves the slab intact, and opening it adds dust, spoil and a wet patch.
Plumber's day -
7
Equipment set on the slab after the repair
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 walk you through the recommended 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 | National estimate. The right first step before anyone considers opening concrete. | $250 to $600 |
| Slab leak drying, one room, flooring stays down | National estimate. 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 | National estimate. 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 | National estimate. 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 wet area of the slab rather than the whole room. | $3 to $7 per square foot |
| Slab moisture documentation before new flooring is installed | National estimate. Our readings against a dry reference area, as supporting evidence alongside the installer's own ASTM testing. | $150 to $400 |
| Your plumber's slab leak repair, reroute or open the slab | 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 typically 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 frequently stays down. Glued hardwood, laminate and carpet with pad typically come up, and removal is labor plus disposal.How much flooring has to be removed
Removal is priced by area, and the marked wet boundary is what keeps it honest. A mapped edge is cheaper than a cautious guess.Whether wall bases wicked moisture up
If the bottom band of drywall reads wet, trim comes off and that band gets dried or removed.Concrete drying days
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 may keep moving into nearby materials even when the surface looks dry.
A slab leak does not drain, it saturates
Water under concrete has nowhere to go, so it soaks the soil and the slab continuously. There is no puddle to warn you and no natural end to it.
Concrete keeps releasing water after the leak stops
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
Adhesives release, laminate cores swell and wood cups when the slab beneath is still giving up moisture. Installers exclude that failure from their warranty.
The soil under the slab can wash out or swell
Continuous water either carries fine soil away or expands clay soils. Both show up as movement, cracked tile and doors that stop closing.

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
A reroute abandons the failed section and runs new pipe overhead or through walls.
Read the explanation
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
Concrete holds water in a fine pore structure and gives it back gradually.
Read the explanation
Drying concrete is a slower science than drying drywall and it needs to be measured rather than assumed.

Common questions
Questions about slab leak damage
What is a slab leak?
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?
Look for a warm spot on the floor, or the sound of running water with everything off. Also check for a water bill that stepped up and stayed up, and damp baseboards under a dry ceiling.
Why is one spot on my floor warm?
Because hot water is escaping under the concrete and heating the slab above it. Warm spots are the single most reliable slab leak symptom in a home.
Do you find the slab leak or does a plumber?
We locate the wet 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?
Not always. Many plumbers prefer a reroute, which abandons the failed run and routes new pipe through walls or the attic.
What is a reroute?
It is new pipe run above the slab to replace the failed section underneath it. Slightly more visible work in walls, and no concrete cutting.
Can concrete be dried, or does it have to be replaced?
Concrete dries. It just does it slowly, because water sits in the pore structure and comes out over days rather than hours.
