Foundation Leak Repair in Keller, TX for Slab Leaks and Drainage Faults
We repair foundation leaks on Keller homes. Water reaches a foundation from two places: a supply or drain line that leaks under or beside the slab, and surface water that runs toward the house. Either one softens or swells the soil, and the foundation moves with it. Call Foundation Repair Keller TX at 123-456-7890 for a free estimate.
We start by finding where the water comes from. A leaking line is traced and repaired. A drainage fault is corrected at the grade, the gutters and the downspouts. Then we check the floor for the movement the water caused.
What We Do About Foundation Leaks in Keller
We test the lines under and around the house
The Texas Section of the American Society of Civil Engineers states that water supply and sanitary drain lines should be tested for leaks if jacking or lifting is part of a repair. We test the lines on every inspection where there is movement, so a leak is found before a lift, not after. Slab leak or foundation problem
We repair the leak at its source
A leaking line is repaired or rerouted, and the soil around it is brought back to stable condition. This Old House's Keller foundation page lists aging plumbing among the causes of foundation problems in Keller, because leaks from old pipes can pool beneath the foundation.
We correct surface drainage
The ASCE guidelines recommend a minimum slope of 5 percent away from the foundation for the first 5 feet all around, and downspouts extended well past the edge of the foundation into well-drained areas. They also state that downspouts should not be connected to perforated pipe subsurface drainage systems. We regrade, extend and redirect as the house needs. Drainage and your foundation
We repair the movement the water caused
Once the water is under control, we measure the floor and repair what moved. Foundation leveling and settlement repair
Work is performed by independent professionals. Every project starts with an inspection and a written price before any work begins.
How We Repair a Foundation Leak
First, we look for the signs of water: damp or warm spots on the floor, soil that stays wet beside the slab, and downspouts that empty at the wall. Second, we test the water supply and drain lines and check the grade. Third, we write the plan with the leak repair, the drainage correction, any movement repair and the price. Finally, we make the repair, measure the floor and walk the result with you.
Why Water Matters on Keller Soil
The ASCE guidelines state that Texas has large areas with clayey soils that shrink and swell with changes in soil moisture, and that maintaining near uniform soil moisture around the foundation may be beneficial. A leak breaks that balance on one side of the house. The USDA soil survey for Tarrant County maps clay soils in patches around Keller, including the Sanger series, which USDA describes as 40 to 60 percent clay with high shrink-swell.
The Dallas/Fort Worth weather station records about 37 inches of precipitation a year, so roof and yard water has a lot of chances to reach the wall. Census Bureau figures show about 90% of Keller's occupied homes were built in 1980 or later, so the lines under most Keller slabs are decades old. Why Keller soil moves foundations
Signs of a Foundation Leak
- A damp, warm or discolored spot on the slab or the floor
- Soil beside the foundation that stays wet in dry weather
- A water bill that rises with no change in use
- The sound of running water when every fixture is off
- A floor that has begun to slope near a bathroom, kitchen or water heater
- Cracks that appeared after a plumbing problem
A leak does not always cause movement, and movement does not always mean a leak. We test to find out which one you have.

Frequently Asked Questions
Can a plumbing leak damage a foundation?
Yes. Water from a leaking line softens or swells the soil under and beside the slab, and the foundation moves with it. The ASCE guidelines state that water supply and sanitary drain lines should be tested for leaks if jacking or lifting is part of a repair. We test the lines when a house shows movement, and we repair a leak before we lift.
How do you find a leak under a slab?
We look for the signs first: a damp or warm spot, a rising water bill and wet soil at the wall. Then we test the water supply and drain lines to isolate the leak. The test result tells us which line leaks and where, and the repair plan names it.
How much does foundation leak repair cost in Keller?
HomeGuide's 2026 national guide lists a foundation leak at $2,000 to $12,000, with minor repairs at $250 to $5,000 and major ones at $4,500 to $15,000 or more. It does not separate slab leaks. Those are national averages, not Keller quotes. The location and depth of the leak set the price, and an inspection gives the real number.
Does fixing drainage stop foundation movement?
It stops the water that feeds the movement, and that is often the first step. The ASCE guidelines recommend a minimum 5 percent slope away from the foundation for the first 5 feet and downspouts extended well past the edge. A foundation that already moved still needs repair, and we measure the floor to tell.
Should I fix a leak before a foundation repair?
Yes. A foundation repaired over an active leak fails again. The ASCE guidelines advise testing the water supply and drain lines for leaks if jacking or lifting is part of the repair. We repair the leak first, then lift and stabilize the foundation.
