Foundation movement and plumbing failure are the same story told twice. The Gulf Coast clay under houses in Porter, Spring, Conroe and The Woodlands swells when it's wet and shrinks hard in an August drought, and that seasonal movement is what cracks slabs, sticks doors — and breaks the water and drain lines running underneath them.
Texas Plumber Connection & Foundation Repair works both sides of that problem, which is genuinely unusual and genuinely useful. There's no service fee to come out and assess a foundation.
The signs worth taking seriously
- Doors and windows that stick or won't latch, especially if it changed with the season
- Diagonal cracks running from the corners of door frames and window frames
- Cracks in brick or mortar, particularly stair-stepping along the joints
- Floors that slope noticeably, or feel bouncy in one area
- Gaps opening between walls and ceilings, or between countertops and backsplashes
- A slab crack you can fit a coin into
Hairline cracks in drywall are normal in a house that's settling in its first few years. Cracks that widen through the year, or come back after being patched, are movement.
Why this soil does it
Expansive clay changes volume with moisture content. After a wet spring it swells and lifts; through a hot dry summer it contracts and the support under parts of the slab falls away. A house doesn't move uniformly — the edges dry out faster than the centre, and a corner near a large tree drying the soil aggressively moves differently again.
The result is differential movement: one part of the foundation supported, another unsupported. That's what produces the cracking pattern, not the settling itself.
The connection most companies don't mention
Here's why we care about doing both trades.
When a foundation moves, the rigid pipe running under and through the slab moves with it. Cast-iron drain lines crack. Copper supply lines fail at joints. That's a large share of the slab leaks we're called to.
It also runs the other way, and this part matters more: a leaking line under a slab saturates the clay beneath it, and saturated clay swells and loses bearing capacity. A slab leak left running for months can cause the foundation movement, not just result from it. Lifting a foundation without finding that leak means paying for the same problem twice.
So we test the plumbing. Before a lift, to find out whether a leak is driving the movement. And after a lift, because raising a foundation back toward level puts real stress on drain lines that have spent years settling into their current position — a hydrostatic test afterwards is how you find out whether the lift just broke something. Foundation companies that don't hold a plumbing capability have to subcontract that or skip it.
How the repair works
- Assess and measure. Establish where the movement is, how much, and in which direction — plus a plumbing test to rule the leak question in or out before anything is priced.
- Plan the pier layout. Where support is needed and how many points, based on the measurements rather than a standard perimeter package.
- Install the piers. Pressed concrete pilings or steel piers driven to load-bearing capacity, depending on soil conditions and depth at your property.
- Lift and stabilise, bringing the slab back toward level — realistically toward level, not to a theoretical perfect plane, which older houses rarely tolerate.
- Re-test the plumbing and repair anything the movement or the lift has compromised.
- Backfill and clean up.
Permitting is handled where the jurisdiction requires it — Montgomery County for unincorporated Porter, New Caney and The Woodlands, or the city in Conroe, Humble, Tomball and Oak Ridge North.
Drainage is half the fix
Piers address the symptom. Water management addresses the cause. If the soil around your foundation goes through extreme wet-dry swings, the movement continues regardless of what's underneath it.
That means gutters and downspouts that discharge well away from the slab rather than beside it, grading that carries water away from the house, correcting negative slope, and in some cases surface or French drains. It's less dramatic than piers and it protects the work.

Porter, New Caney, Spring, The Woodlands, Conroe, Oak Ridge North, Cut and Shoot, Humble, Atascocita and Tomball — all of it on the same expansive clay.
We'll look at it and tell you honestly what we see, including when the answer is that what you have is normal settlement, or a drainage problem, or a slab leak rather than a foundation job. Estimates run Monday through Saturday, 8am to 8pm, with financing available through Synchrony.
