What Foundation Work Costs in Overland Park, Job by Job
These numbers come from published national cost guides, not from Overland Park contractors. They're a fair starting point for a budget, and a quick way to see whether a bid sits in a normal range.
Typical 2026 ranges: $250–$800 per sealed crack, $1,600–$3,000 for wall anchors along 20 feet of wall, $800–$1,500 for a sump pump installed, $4,000–$12,000 for bowing wall repair and $4,500–$20,000 for a settling foundation (HomeGuide; Angi). These are national guide figures, not an Overland Park quote.

How to read these ranges
Cost guides gather prices from around the country and publish a typical band. Local labor, permit fees and the condition of your walls can push your number either way, so use the table to sanity-check a bid, not to predict it.
Angi puts the national average for foundation repair at $5,174, with most projects between $2,225 and $8,133 (2026). Some jobs are one line of the table; others combine two or three.
Three common Overland Park scopes
- One leaking crack in a poured wall. Injection at $250–$800 per crack (HomeGuide, 2026). The city lists epoxy injection as minor maintenance that doesn't need a repair permit.
- A block wall bowing at mid-height. Anchors or straps along about 20 feet of wall run $1,600–$5,600 in HomeGuide's bowing-wall guide; a badly bowed wall may need tiebacks or straightening instead.
- A basement that's wet every spring. A sump pump at $800–$1,500 installed (Angi, 2026), sometimes with interior drain tile, which HomeGuide puts at $4,000–$17,000 depending on length.
What moves a quote up or down
- Wall type and movement. Inches of lean decide whether straps will do or anchors and tiebacks are needed.
- Depth to firm bearing. Piers are driven until they reach solid support. Where limestone sits shallow, as it does at some points in the USDA soil sample, that can come sooner; where deep clay continues, it takes more steel.
- Finished basements. Drywall, flooring and built-ins have to come out and go back.
- Engineering. A structural engineer's report is $500–$3,000 in HomeGuide's 2026 guide, when one is called for.
Before you sign
- Ask for a written, itemized price: the system, the count of anchors, straps, piers or injection ports, and the measurement behind each.
- Ask for the warranty terms in writing, including whether they transfer if you sell.
- Look up the contractor's Johnson County license with the county's online search.
- Confirm who pulls the city permit, and that any digging is called in to Kansas 811 at least two full working days ahead, as Kansas law requires (K.S.A. 66-1804).
Cost questions
How much does foundation repair cost in Kansas?
The major cost guides don't publish a Kansas-only figure. Nationally, Angi's 2026 guide puts the average at $5,174 and the typical project at $2,225–$8,133. Overland Park bids will vary with the wall, the soil and how much finished space is involved.
What's the cheapest fix for a leaking crack?
Injection, at $250–$800 per crack in HomeGuide's 2026 guide. It suits a poured wall with a crack that leaks but isn't moving. If the wall is also leaning, sealing the crack alone won't hold.
Is a sump pump cheaper than waterproofing?
Usually. Angi's 2026 figures put a sump pump at $800–$1,500 installed, against $2,461–$8,203 for basement waterproofing overall. Many wet basements need the pump plus some drain tile, so ask for those lines priced separately.
Can I get a firm price over the phone?
Not a reliable one. The same crack can be a quick injection or the first sign of a wall that needs anchors. A price worth comparing comes after someone measures the walls.
