The clay moved. The pipe cracked. Now the hall closet smells like a creek bed.

A soft spot in the carpet is a slab telling you something

You noticed the carpet by the hall bathroom felt cool, then damp, then the baseboard behind it went dark. Nobody spilled anything. In a Plano house on a post-tension or conventional slab, that pattern almost always means a supply line or a drain line under the concrete has opened, and the water has been wicking up into the bottom plate and the drywall for weeks.

An independent local provider starts with a moisture meter, not a demolition hammer. The crew reads the wall on both sides, follows the wet line down the hall, and marks where the reading drops back to normal. That mark decides how much drywall and pad come out. Then a plumber locates the break under the slab, because remediation over an open leak is wasted money.

Texas licenses this trade through the Texas Department of Licensing and Regulation, and a job that disturbs more than 25 contiguous square feet of growth needs a licensed remediation contractor. The repair side, hanging new drywall and resetting trim, is ordinary contractor work. Calling this number puts you through to a provider who does the removal and can tell you where the rebuild starts.

What the crew sets up in a Collin County house before the first cut

What happens	What it means for you
Plastic zips across the hallway, and the supply and return grilles in that wing are taped shut	Dust from the wet drywall stays in one room instead of riding the ductwork into the bedrooms
A HEPA air scrubber exhausts the work zone through a window	The room sits under negative pressure, so particles pull inward rather than drifting toward the kitchen
Drywall, pad, and baseboard cut to the meter reading, not to the stain	Two wet feet of wall come out when two wet feet are the problem, not the whole hallway
Studs, bottom plate, and the slab edge HEPA vacuumed and wiped	The framing that stays is cleaned, not boxed in damp
Air movers and a dehumidifier run until the slab and framing read dry	New drywall waits for dry wood, not for a date on a calendar
The line between removal and rebuild written down before any demolition	You know which company puts the wall back and roughly what that involves

Before you bleach the baseboard and hope

A patch smaller than a dinner plate on tile, grout, or painted brick is a detergent-and-rag job. A patch on drywall, carpet pad, a cabinet floor, or a closet ceiling is not; bleach soaks the paper face and leaves the growth inside the gypsum. Close the door, keep the air conditioning running, take photos, and look for what fed the spot: the water heater pan, the fridge line, the washer box, or a bathroom on the other side of the wall.

Why a Plano slab leaks and a Plano attic drips

Plano sits on the Blackland Prairie at about 715 feet, on clay that swells when the spring rains come and shrinks hard through July and August. Most of the city was built between 1970 and 2000, when the population climbed from under 18,000 to more than 222,000, and nearly all of it sits on a concrete slab. When the clay moves, the slab flexes, and the copper supply lines and cast iron drains under it crack at the joints. That is the leak behind most of the slow mold calls east of Central Expressway.

The second water source is overhead. North Texas summers run above 95 degrees for weeks, the air handler sits in a 130-degree attic, and a clogged condensate line fills the drain pan and spills onto the ceiling drywall below. Hail adds a third: on April 11, 2016, stones up to 2.5 inches fell on north Plano and softball-size hail hit Wylie, and a roof that lost shingles that night let rain onto the decking for months afterward. The February 2021 freeze added a fourth, when attic lines split across Collin County and ran for days.

Plano buys its water from the North Texas Municipal Water District, which has pulled from Lavon Lake since the 1950s, and a jump on your city utility bill with no change in habits is often the first sign a slab line has opened. The National Weather Service office in Fort Worth keeps the hail and flood record for the county if your adjuster asks for a date.

Does a Texas homeowners policy pay for slab-leak mold?

We do not know what your policy pays, and we promise nothing about it. Most Texas homeowner policies cover a sudden pipe failure, exclude a leak that ran for months, and cap mold at a set dollar amount unless you added an endorsement. The provider photographs the growth, logs the moisture reading on every wall, and hands you a written scope. Your adjuster decides from that record. If water is still running, shut the main at the meter box by the curb and call before the adjuster comes.
