Foundation repair in The Woodlands

Foundation trouble in The Woodlands usually traces back to water pumped from deep underground. The Harris-Galveston Subsidence District reports the region's largest historical drop in Chicot-Evangeline aquifer levels, over 400 feet, around The Woodlands, and the USGS puts land subsidence here at about 2.5 feet through 2021. Because the community sits in Montgomery County, outside that district's rules, the pumping story is different from inner Houston. This page covers what that means for a slab, the fault warning, Township approval and costs. Nearby places are on the Houston areas page.

Why has the ground under The Woodlands dropped so far?

The sinking follows the water levels. As wells drew down the Chicot-Evangeline aquifer, the clay layers between the sands squeezed and the surface sank. HGSD measures the largest historical water-level decline in that aquifer around The Woodlands, more than 400 feet. The USGS estimates about 2.5 feet of subsidence here through 2021, most of it since 1987.

The USGS also found that about a third of the sinking at The Woodlands, roughly 33%, comes from compaction of the deeper Jasper aquifer, a larger share than in Spring to the south. The same report notes that subsidence often carries on at a slower rate while water levels stay near their historical lows. So a level reading today doesn't mean the ground has finished moving.

Who controls the pumping behind it?

Groundwater in Montgomery County is regulated by the Lone Star Groundwater Conservation District, which the Texas Legislature created in 2001 to conserve and protect the county's groundwater. The Harris-Galveston Subsidence District, whose plan required much of Harris County to cut groundwater use, covers Harris and Galveston counties, not The Woodlands.

HGSD's 2025 report shows what those rules did inside its area: water levels near the Houston Ship Channel rose over 200 feet once pumping was cut. Where groundwater stayed the main supply, levels fell. So the trend under The Woodlands depends on a different agency's decisions.

Could old faults start moving again here?

Researchers think it's likely if pumping continues. A University of Houston team led by geology professor Shuhab Khan, publishing in the journal Remote Sensing, found substantial subsidence in The Woodlands and warned that faults here and in Katy will likely become reactivated if current groundwater pumping trends continue.

No pier holds a house still against ground that is splitting underneath it. That is why, in The Woodlands, a contractor's first job is diagnosis, not lifting. A thorough foundation inspection here should take floor elevations across the whole slab and ask whether the low side lines up with anything beyond your lot. If it does, a structural engineer's report, typically $500 to $1,000, is money well spent before anyone prices piers.

Do I need Township approval before foundation work in The Woodlands?

Probably, so check first. The Woodlands Township's covenant rules say that the construction, alteration or repair of any structure or improvement on a lot with an existing home must have the prior written approval of the village's Residential Design Review Committee or its designated staff. Foundation repair isn't named on the Township's chart of improvements, so ask Covenant Administration before work begins.

Each developed village elects its own committee of at least three resident volunteers, who serve one-year terms and meet at least once a month. Applications go through the Township's online Civic Access Portal. Some neighborhoods add their own criteria.

The Township is a special-purpose local government formed in 2010, not a city, and The Woodlands sits outside the City of Houston, whose building permit rules don't apply here. Ask Montgomery County's permit office whether a county permit is needed for your address.

What should a repair quote for a Woodlands house allow for?

Expect a quote built around a slab. The Woodlands was founded in 1974 by developer George P. Mitchell, so most of its houses date from the era when Houston-area homes went onto concrete slabs rather than raised pier-and-beam. The usual fix for a section that has dropped is slab foundation repair with piers, followed by foundation leveling to bring floors back toward true.

The soil is also not the heavy coastal clay of south Houston. Loamier soils such as the Splendora series, whose type location is in Montgomery County, are common in this part of the region; the inspection confirms what is under your lot.

On price, most Houston-area jobs land between $3,300 and $6,800, with pressed concrete piers about $300 to $600 each and steel piers from about $1,000. What lifts a Woodlands bill is the extra checking: an engineer's report, or a soil report at $500 to $3,000 where subsidence or a fault is suspected. The foundation repair cost page breaks the ranges down. A local foundation contractor gives you the real figure in a written quote after the visit we'll arrange.
