Foundation Repair Cost in Katy, TX in 2026
Foundation repair pricing in Katy varies more than a single number can capture, because the right fix depends on your soil depth, how many piers your slab actually needs, and whether drainage correction has to happen alongside the structural work. Homes in Cinco Ranch, Grand Lakes and Elyson sit on similar Gulf Coast clay to Old Katy's older pier-and-beam houses, but the repair method and cost can look very different. This guide breaks down 2026 pricing across the Houston metro for the pier types, slab leveling methods and drainage work most commonly quoted in Katy, so you can sanity-check a bid before you sign.

What drives the price of a Katy foundation repair
The biggest cost driver is pier count, which your engineer's report determines based on measured floor elevations and how far the slab has moved, not a flat per-linear-foot rule of thumb. A minor perimeter dip might need 6 to 8 piers, while a home with significant settlement on one side can need 15 or more.
Access also matters. Piers placed under a deck, a mature tree's root zone, or a tight side yard between houses in denser subdivisions like Cinco Ranch cost more to install than open perimeter access in newer sections of Cane Island or Elyson.
Pressed piling versus drilled piers versus steel push piers
Pressed concrete piling is the most common and generally most affordable method used across the Katy metro for slab-on-grade homes, running roughly $350 to $650 per pier, pushed hydraulically using the home's weight as leverage until refusal in stable soil.
Drilled, bell-bottom concrete piers cost more, typically $450 to $800 per pier, because they're excavated deeper to reach more reliable bearing strata, which some engineers prefer for homes with more severe or long-standing settlement. Steel push piers, at $900 to $1,800 per pier, cost the most but work well in tight-access spots or where deeper, more predictable load capacity is needed.
Slab leveling: mudjacking versus polyjacking
For interior slab areas that have dipped without needing full perimeter piering, mudjacking pumps a cement-based slurry under the slab to fill voids and lift it back into place, typically running $600 to $2,500 depending on the size of the affected area, and remains common for larger, budget-conscious jobs.
Polyurethane foam injection, or polyjacking, costs more per project, generally $800 to $3,200, but the foam is lightweight, cures within about 15 minutes, and resists moisture intrusion, which matters in Katy's clay where repeat saturation is common. Ask whether your contractor is filling the void completely rather than just lifting the visible surface, since incomplete fill leads to repeat settling.
Old Katy pier-and-beam pricing is different
The pocket of older pier-and-beam homes in Old Katy near the historic downtown gets leveled differently than the slab homes that dominate the rest of the metro. Leveling typically involves adjusting or replacing wood or concrete piers under the beam and shimming, running roughly $4,000 to $10,000 depending on how many support points need adjustment and whether any beams or joists show rot that needs replacing along the way.
Drainage correction is often part of the real cost
Because clay shrink-swell is driven by moisture, many Katy foundation jobs include or are followed by drainage work: regrading soil away from the slab, adding gutter extensions, or installing a French drain system, running $3,500 to $12,000 depending on scope. Skipping this step is a common reason homeowners see the same section of slab move again within a few years, particularly in low-lying pockets near Mason Creek or the Addicks/Barker watershed.
A soaker hose or drip irrigation system placed along the foundation perimeter, $300 to $900 installed, is a much smaller but commonly recommended add-on to keep clay moisture more consistent through Houston's dry summer months.
Getting an accurate quote for your home
A trustworthy quote should break out pier count and type, permit and engineer's letter costs, any drainage work, and warranty terms including transferability, rather than a single lump sum. If two bids differ by thousands of dollars, ask each company to show their engineer's elevation measurements so you're comparing scope, not just price. Ready to compare real bids?

Common questions
What's the average cost of foundation repair in Katy?
Most full perimeter underpinning projects using 8 to 14 piers run $5,500 to $14,000, with pressed piling running $350 to $650 per pier and drilled or steel piers running more. Interior slab leveling with mudjacking or polyjacking typically runs $600 to $3,200.
Is pressed piling or drilled pier better for a Katy home?
Pressed piling is more affordable and works well for many Katy slabs, while drilled bell-bottom piers reach deeper bearing soil and are often specified for more severe settlement. The right choice should come from your engineer's report, not price alone.
Does foundation repair cost more in Old Katy than Cinco Ranch?
It's a different type of job rather than simply more or less expensive. Old Katy's pier-and-beam homes are leveled by adjusting support piers under the beam, typically $4,000 to $10,000, while Cinco Ranch's slab-on-grade homes are repaired with perimeter piering priced per pier.
Is drainage work included in a Katy foundation repair quote?
Not always, and it should be itemized separately if recommended. Given how much clay shrink-swell drives Katy foundation movement, many engineers recommend pairing piering with drainage correction, which typically adds $3,500 to $12,000 depending on scope.
