Olson has handled foundation repair in Independence, MO since 1986. We fix cracked block walls, bowing basement walls, settling corners, and wet basements, and we do it with published prices and a free inspection.
The median Independence home was built in 1967, so most foundations here have ridden nearly sixty cycles of Jackson County clay swelling in spring and shrinking in August. Movement is common. Whether yours is cosmetic or structural is what the inspection settles.
Independence covers 78 square miles across 24 separate watersheds, with a northern boundary that runs to the Missouri River. A rubble limestone wall two blocks off the Square and a poured wall in a 1998 subdivision off R.D. Mize Road have almost nothing in common except the clay underneath them.
Knowing which part of the city your house sits in tells us most of what we need to know before we arrive.
| Area | Era | What typically fails |
|---|---|---|
| Around the Square, North and South Main | Pre-1920 | Rubble limestone walls losing mortar, bulging, shedding material |
| Fairmount, Mount Washington | Over half pre-1939 | Early block and stone, no working drain tile, tight lots with no fall |
| Truman, Englewood, Procter, Bristol, Golden Acres | 1910 to 1940 | Block walls, original grading, Heritage District approval on exterior work |
| Santa Fe, Maywood, Rock Creek, Three Trails, south of 23rd | 1945 to 1975 | Hollow block bowing under lateral clay pressure, collapsed clay tile |
| Eastland, Hartman, the I-470 and Little Blue Parkway corridors | 1980s to 2000s | Poured walls on engineered fill, differential settlement, regraded lots |
| North bottoms toward Courtney and Atherton | Varies | Soft alluvium and a high water table, helical piers over driven |
Independence sits on deep silty clay loams formed in loess, with Sharpsburg and Knox the common upland series. They are slow to take water in. Rain soaks down a few feet, meets dense clay, and stops there rather than draining away. The metro takes roughly 38 to 42 inches of rain a year and takes it unevenly, with May the wettest month by a wide margin and midwinter the driest, so the clay swells every spring and shrinks every August.
With a median build year of 1967, most Independence foundations are concrete block, which carries downward load well and sideways load poorly. That is why bowing walls and stair-step cracks are the most common failure here, and why the fix is usually anchors rather than piers.
The right repair depends on which of those situations your house is in. Here is what we install and when we recommend it.
For a dropping corner, sloping floors, or cracks wider at the top than the bottom. Steel piers carry load down past the active clay to stable strata. Helical piers are the answer where access is tight or the soil is soft, which covers both the older lots west of Noland Road and the alluvial ground on the north end.
The most common structural fix in the postwar belt. Saturated clay pushes sideways until a block wall cracks horizontally or stops standing plumb. Deadman anchors hold it and stop the movement. Where there is room to excavate outside, a wall push can bring it back toward straight rather than freezing it where it stands.
Injected under pressure, epoxy or polyurethane travels the full thickness of the wall instead of bridging the visible face. The caveat is worth hearing before you buy: sealing a crack in a wall that is still moving buys you a season. On a poured wall in a 1990s subdivision that is usually the whole fix. On a bowing block wall it is not, and we will say which one you have.
Specific to the oldest part of the city. Limestone walls hold by mass and friction rather than tensile strength, so when the mortar washes out the wall bulges and sheds. That is a repointing and stabilization job. Tuck pointing runs $15 to $20 per foot on stone and block. We do not service brick.
Clay swells because it takes on water, so water management is often the actual repair. If the cause is dead drain tile, downspouts discharging at the wall, or grade falling toward the house, we address that rather than quoting piers you do not need. Interior drain tile with a sump pump solves most Independence water problems without touching the yard.
Driveways, garage slabs, and patios settle over the same clay. We lift them with polyurethane instead of tearing them out.
An undersized gutter dumping hundreds of gallons per storm beside your footing is a foundation problem in a different costume. We handle that end of it too.
An inspection is a diagnosis, not a walkthrough. Here is what we actually measure and why each one matters.
You get the findings verbally while we are standing there, then an itemized written bid you can hold next to another company’s and compare line by line.
We publish our rates because none of the companies currently ranking for this search do. Use these to ballpark the job. A walkthrough gives you the real number.

Four things move your number, and they are worth understanding before you compare bids:
Full price list lives on our foundation repair cost page, and we offer financing, because this is rarely an expense anyone planned for.
Missouri issues no statewide general contractor license, so licensing is handled city by city and verification falls to you. Four things to confirm before signing:
A current City of Independence license. Contractors need a business license and a contractor license, and contractor licenses expire every December 31. Both are in the city’s public lookup. A Kansas City or Johnson County license does not carry over.
Who pulls the permit. Structural foundation work is permitted work under the 2018 IRC and IBC, and pulling it is the contractor’s job, not yours. Building Inspections: 816-325-7401.
Heritage District approval, if it applies. Exterior work in the Truman Heritage District west of the Square usually needs a Certificate of Appropriateness. The Heritage Commission meets monthly, so a contractor unfamiliar with it can cost you a month.
Where the sump discharges. City code prohibits draining storm, surface, or groundwater into the sanitary sewer. A sump line tied into the sanitary lateral is a violation, and it is common in older homes.
Any foundation company worth hiring answers all four without hesitating.
Call (913) 592-3300 or request your free in-home consultation. No charge and no deposit, and we run eastern Jackson County daily, so most Independence appointments book fast.
Our local experts walk the exterior first, then the basement or crawl space. You get the diagnosis in plain English while we are still standing there, plus an itemized written bid with real options instead of one take-it-or-leave-it number.
We pull the Independence permit, confirm whether your address falls inside the Heritage District, and work on the date we gave you. Crack injections are frequently one day; pier and drainage jobs run one to three. The site gets cleaned before we go.
You get the warranty walkthrough before the first hole is drilled, not in a folder afterward: what is covered, for how long, and what transfers if you sell.
We work citywide: Fairmount and Mount Washington on the north bluffs, the Truman neighborhood, Englewood, Procter, Bristol, and Golden Acres west of the Square, the postwar belt through Santa Fe, Maywood, Rock Creek, and Three Trails, and out to the Eastland and Little Blue Parkway corridors.
We also work next door in Raytown, including Blue Springs, Lee’s Summit, Gladstone, Liberty, and the wider Kansas City metro. Full service area here.
Most jobs run $4,000 to $15,000, with steel piers at $1,600 to $1,800 each and crack injection at $40 to $50 per foot. Small repairs can be a few hundred dollars. Our inspections are free, which is the only way to get a number that means anything.
Yes. Independence runs its own building department under the 2018 IRC and IBC, and structural foundation work is permitted work. Your contractor should pull it as part of the job rather than handing it to you.
It can. Exterior work that alters the property’s appearance generally needs a Certificate of Appropriateness from the Heritage Commission, which meets monthly. Interior repairs such as anchors or interior drain tile typically do not trigger it.
Because most of the city predates 1970 and was built with hollow concrete block, which handles downward load well and sideways load poorly. Jackson County clay expands against those walls every spring until a mortar joint gives.
Most stone walls near the Square can be repointed and stabilized rather than rebuilt. It depends on how much the wall has displaced and how much mortar is left, which is what the inspection determines.
To the surface or the storm system, never the sanitary sewer. Independence city code prohibits draining storm, surface, or groundwater into the sanitary system, and the city operates fully separate networks.
Usually not. Carriers treat soil movement as maintenance, not a sudden loss, and exclude it accordingly. Where it gets interesting in older Independence homes is plumbing: a supply line that has been leaking under a footing may be a covered event even when the resulting settlement is not. Get your policy language in front of your agent before you assume either way.
Usually, yes, and in the Truman Heritage District it is often the only practical route, since interior work does not trigger a Certificate of Appropriateness the way regrading or a visible discharge line can. Interior drain tile tied to a sump handles most of what we see. Exterior digging earns its cost only when the grade itself is the cause.
Not always, though it is reasonable if you want an opinion with no financial stake in the outcome. Our inspection is free and diagnoses the problem; an engineer’s independent report runs a few hundred dollars. We are glad to work from one.
Crack injections are usually a day. Pier and waterproofing work runs two to five. Wall rebuilds and larger structural jobs stretch past a week, and on the older west-side lots, access is what drives that more than the work itself.
Documentation is the asset, not the absence of a problem. Eastern Jackson County buyers order inspections and their lenders read them, so a foundation issue that shows up undisclosed is what stalls a closing. A transferable warranty and a paid invoice turn it into a resolved item on the report.
You have the prices, the local context, and a straight account of what we will and will not recommend. The next step is someone standing in your basement telling you what is actually happening down there.
