Signs to look for

When to call us for slab leak damage

As hidden moisture is traced, if you notice any of these problems, call us before water has more time to spread into nearby materials.

A warm spot on a tile or wood floor

From the first damage clue, heated water escaping under the concrete warms the slab above it.

You hear water running with everything turned off

As hidden moisture is traced, stand in a quiet room at night and listen at floor level.

The water heater cycles constantly

To protect nearby materials, 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

During the watchful inspection, 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

To protect nearby materials, 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

From the first damage clue, grout is the most permeable part of a tile floor, so moisture appears there first.

What happens

How we handle slab leak damage

Our moisture-tracing team adjusts the work to what got wet, how far the water traveled, and which materials can be saved.

Confirming the water is coming from below

From the first damage clue, we rule out the roof, the walls and every fixture in the area first.

Locating the leak so nobody cuts on a guess

During the watchful inspection, 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

From the first damage clue, the wet boundary gets drawn on the floor and recorded in a map.

Extraction of the water that came up through the slab

During the watchful inspection, standing water, wet carpet and pad, and water sitting under a floating floor all get removed.

Flooring removal only where it has to come up

During the watchful inspection, tile with sound thinset and grout often stays down.

Wall base and cavity drying where water wicked up

From the first damage clue, drywall pulls moisture up from a wet slab by wicking, so the bottom band of the wall gets metered and dried.

3
Ruling out everything above the slab first

From the first damage clue, on arrival the lead checks fixtures, walls and the ceiling in the affected area.
On arrival
4
The wet area mapped and marked on the floor

To protect nearby materials, 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

From the first damage clue, 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

From the first damage clue, 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

To protect nearby materials, air movers over the concrete, Professional dehumidifiers taking moisture out of the air, and negative pressure under floating assemblies where the system allows it.

Understanding the cost

What can affect the price

As hidden moisture is traced, we explain the recommended work and price before you approve the job. As hidden moisture is traced, 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	During the watchful inspection, national estimate. From the first damage clue, the right first step before anyone considers opening concrete.	$250 to $600
Slab leak drying, one room, flooring stays down	During the watchful inspection, national estimate. To protect nearby materials, 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	During the watchful inspection, national estimate. From the first damage clue, 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	During the watchful inspection, national estimate. To protect nearby materials, 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	During the watchful inspection, national estimate. From the first damage clue, 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	During the watchful inspection, national estimate. During the watchful inspection, 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 recovery plan, listed so the total is not a surprise.	$1,000 to $6,000

How long the leak ran before it was found
As hidden moisture is traced, slab leaks are usually found late, and every week widens the saturated area under the floor.
Hot side or cold side
To protect nearby materials, 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
During the watchful inspection, tile with sound thinset often stays down.
How much flooring has to be removed
As hidden moisture is traced, removal is priced by area, and the marked wet boundary is what keeps it honest.
Whether wall bases wicked moisture up
During the watchful inspection, if the bottom band of drywall reads wet, trim comes off and that band gets dried or removed.
Concrete drying days
From the first damage clue, 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

To protect nearby materials, water can keep moving into nearby materials even when the surface looks dry.

A slab leak does not drain, it saturates

As hidden moisture is traced, water under concrete has nowhere to go, so it soaks the soil and the slab continuously.

Concrete keeps releasing water after the leak stops

As hidden moisture is traced, 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

As hidden moisture is traced, 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

During the watchful inspection, continuous water either carries fine soil away or expands clay soils.

Helpful service information

What to know about slab leak damage

During the watchful inspection, start with the short explanation. To protect nearby materials, open a card if you want a little more detail.

What is happening inside the property

During the watchful inspection, in slab on grade construction, water supply lines are commonly run inside or beneath the concrete, historically in soft copper tubing.

Read the explanation

During the watchful inspection, it helps to know what is actually down there. During the watchful inspection, 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

During the watchful inspection, a reroute abandons the failed section and runs new pipe overhead or through walls.

Read the explanation

During the watchful inspection, 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

From the first damage clue, concrete holds water in a fine pore structure and gives it back gradually.

Read the explanation

To protect nearby materials, 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?

As hidden moisture is traced, 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?

During the watchful inspection, 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?

During the watchful inspection, because hot water is escaping under the concrete and heating the slab above it.

Do you find the slab leak or does a plumber?

As hidden moisture is traced, 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?

During the watchful inspection, not always. During the watchful inspection, many plumbers prefer a reroute, which abandons the failed run and routes new pipe through walls or the attic.

What is a reroute?

As hidden moisture is traced, 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?

During the watchful inspection, concrete dries. As hidden moisture is traced, it just does it slowly, because water sits in the pore structure and comes out over days rather than hours.
