Foundation repair in Friendswood

Foundation repair in Friendswood starts with the creek. In Hurricane Harvey, the Harris County Flood Control District recorded the worst flooding of structures ever seen along Clear Creek and its tributaries, Cowart Creek among them, so many Friendswood slabs and pier-and-beam floors have sat in floodwater at least once. That history shapes what a local foundation contractor looks for and which paperwork the City of Friendswood wants. This page covers the flood record, the city's permit system, the FEMA buyouts and what drives a Friendswood quote. For other parts of the region, see the Houston areas page.

Did Harvey's Clear Creek flooding damage Friendswood foundations?

Harvey put more Friendswood homes under water than any storm before it. HCFCD reports that record flooding ran along the whole of Clear Creek and its major tributaries, including Cowart Creek and Mary's Creek, with levels at or above the 500-year mark. Water beat the 1979 Tropical Storm Claudette records by 2 to 3 feet. A house that flooded then deserves a closer look at its foundation now.

The rain itself was extreme on this side of the county. HCFCD placed the heaviest totals along I-45 from South Houston and Pasadena down to Friendswood and Webster, with 47.4 inches in four days at Clear Creek and I-45. That gauge is shared with Clear Lake, downstream on the same creek.

In the Harris County part of Friendswood alone, HCFCD counted about 1,750 flooded houses. The rest of the city is in Galveston County; the report notes that the largest concentration of flooded homes outside Harris County was along Clear Creek in northern Galveston and Brazoria counties. Those homes are not in the 1,750 figure.

Floodwater can soften the soil under a slab edge and soak the beams and sills of a raised floor. If doors started sticking or new cracks showed after the water went down, a foundation inspection separates settling that has stopped from movement that is still going.

Who issues a foundation repair permit in Friendswood?

Friendswood is its own city, so City of Houston permits do not apply here. The City of Friendswood runs permits through its Community Development department and has moved fully to online permits: applicants register on the city's portal, then apply, pay and book inspections there. The city's page does not list foundation repair by name, so ask Community Development whether your job needs one before work starts.

Ask the contractor who pulls the permit and books the inspection, and mention on the call if the house sits in a mapped flood zone near Clear Creek or Cowart Creek.

The subsidence side is simpler. Both of Friendswood's counties, Harris and Galveston, fall under the Harris-Galveston Subsidence District, which the Texas Legislature created in 1975 to limit groundwater pumping and stop the land sinking.

What happened to the Friendswood homes FEMA bought out?

In 2020, FEMA awarded the City of Friendswood more than $5.6 million to buy and demolish 26 flood-prone homes affected by Harvey. The money came from FEMA's Hazard Mitigation Grant Program with a 25 percent nonfederal match, and the cleared lots stay as open space so nothing is built there again. If your street lost neighbors this way, your own lot shares the same flood exposure.

That matters for a repair decision. Lifting and piering a slab is money well spent when the soil is the problem. When repeated flooding is the problem, it pays to ask the city about the house's flood zone and past claims before committing to a large job, and to see whether better grading and foundation drainage should come first.

Should a flooded Friendswood house be leveled or just drained?

It depends on whether the floor is still moving. A contractor measures the floor with a level survey, checks the slab edge and the yard for low spots, and looks at where gutters and downspouts empty. If the readings are stable and the cracks are old, drainage work and crack sealing may be enough. If one side keeps dropping, foundation piers under that section are the usual fix.

Raised houses near the creek need a different check. On a pier-and-beam floor the inspector crawls under to look for wet or rotted sills, shifted blocks and sagging joists, and the answer is often shims and new supports rather than piers. The pier-and-beam foundation repair page explains that work.

What does foundation repair cost on a Friendswood lot?

A 2026 Houston guide puts most jobs at $3,300 to $6,800, with concrete piers at $300 to $600 each and steel piers from about $1,000. A Friendswood quote moves with the number of piers, how hard the slab edge is to reach, and whether any work has to happen inside the house.

The same guide says access problems add 6 to 8 percent to pier costs and interior work adds about 15 percent, which counts on lots with fences close to the slab or additions built over the old foundation. A national guide adds $75 to $150 for permits and $500 to $1,000 for a structural engineer's report. The full breakdown is on the foundation repair cost page.
