Foundation Repair in Grandview, MO
Most homes that need foundation repair in Grandview, MO share the same story. They were built between 1959 and 1979; they sit on clay, and their lower level is half in the ground. Over the years, that clay shows up as a crack at the split, a bowing wall, or water after a hard storm.
Olson Foundation Repair has been fixing exactly these problems since 1986, from a shop about 15 minutes away. When you call, we start by finding out why your house moved, then walk you through the fix and the price. That first visit is free.
Why Grandview Foundations Move
Grandview nearly tripled in the 1960s as Richards-Gebaur Air Force Base drew families in. Builders answered with raised ranches, split-entries and side-to-side splits, and the median home here dates to 1973.
That era, plus the clay, sets up four problems:
- Half-buried walls. Clay pushes on the buried part of a raised ranch or split-entry wall, so cracks run horizontally just below the soil line.
- Two depths, one house. In a side-to-side split, one section moves and the other does not. The crack shows up at the step.
- Swelling clay. The local silty clay runs 33 to 42 percent clay. It swells every wet spring and shrinks every dry August.
- Age and slope. About 72 percent of homes predate 1980, and old footing drains are often clogged. Many lots also slope toward a creek, which loads the downhill wall.
Part of Grandview | Built | What we check first |
Old Town, Highgrove Rd, 10th St | 1912 to 1940s | Older walls, mortar loss, settling porches |
Grandview Park Manor, Meadowmere | Late 1950s to early 1960s | Bowing block walls, stair-step cracks |
Mapleview, Valley View Estates, Hunter Gardens | Late 1960s to early 1970s | Horizontal cracks, wet cove joints |
Byars Gardens and other 1970s splits | 1970s | Cracks at the split, uneven floors |
Newer homes near E 135th St | 2010s | Settling corners, leaking shrinkage cracks |
Lots near the Little Blue and creeks | Mixed | High water, sump capacity |
The Water Side: Creeks, Storms and Sewer Backups
The Little Blue River starts in Grandview, and its flooding is getting worse. 2017 storms did about $4 million in damage to city roads and culverts, and homes on Merrywood Circle and near 71 and 150 Highway have taken water in their basements.
For your foundation, that means the clay around your walls stays wet longer than it should. Wet clay is heavier and swells harder against the wall.
Not every wet basement is a foundation problem, though. Here is how to tell:
- Water through the floor drain during a storm is usually a sewer backup. That is a plumbing fix, often a backflow valve.
- Water at the cove joint, a wall crack, or a window well is ours. Interior drain tile and a sump usually solve it. See basement waterproofing in Grandview.
- Water pooling against the house points to grading, gutters, or downspouts. The ground should drop about 6 inches over the first 10 feet, and downspouts should discharge 5 to 10 feet out. We handle drainage and gutters too.
What Foundation Repair in Grandview, MO Usually Involves
The fix depends on how your wall or footing moved. We do not sell one system and make your house fit it.
House Foundation Repair With Concentric Push Piers
When it fits: a dropped corner, sloping floors, sticking doors, or diagonal cracks off windows and doors.
What it does: Steel piers are driven under your footing to load-bearing strata below the active clay. “Concentric” means the load sits centered under the footing, so the pier carries it straight down.
- 5-foot steel sections joined by 12-inch inserts
- A 12 x 18 inch access hole per pier
- Typically about 22 feet deep, extendable to 70 feet
- $1,600 to $1,800 per pier
Piers are usually spaced 5 to 7 feet apart, so a 2,000 square foot house might need anywhere from 4 to 10, depending on how much of it has settled. On a split-level, often only the settled section needs piers. See push piers in Grandview and our foundation piering guide.
Bowing Basement Wall Repair: I-Beams, Deadman Anchors and Wall Pushes
This is the most common structural repair in Grandview’s raised ranches and split-entries. There are three ways to fix it:
- Steel I-beams (7.7s). Anchored to the floor and fastened to the joists, all from inside with no digging. Spaced about 4 feet apart on block walls and 5 to 6 feet apart on poured walls. A good fit when a driveway or patio sits against the wall. $500 to $700 per beam.
- Deadman anchors. A steel rod runs through the wall to an anchor buried in the yard, then gets tightened from inside. Needs yard room on that side. $1,100 to $1,300 per anchor.
- Wall push. We dig outside, relieve the pressure, push the wall back toward plumb, and waterproof it. $325 to $375 per foot.
If the block has crushed, bracing will not hold, and a rebuild ($90 to $120 per sq. ft.) is the honest fix. See bowing wall repair in Grandview and wall bracing.
Foundation Crack Repair
- Epoxy injection fills the crack through the full thickness of the wall. $40 to $50 per foot.
- Surface patching is cosmetic only. $12 to $18 per foot.
A crack wider than 1/8 inch, or one that keeps growing, is worth a look. Pencil-mark both ends and check it again in 30 days. On a poured wall in a newer Grandview home, injection is often the whole fix. On a block wall that is still moving, it is not, and we will say so before you pay for it. More on wall crack repair.
Basement Waterproofing in Grandview
- Interior drain tile, $75 to $90 per foot, carries water to a sump
- Sump pump, $1,800 to $2,000, including pit, pump, lid, and discharge line
- Sump with battery backup, $2,400 to $2,600
The battery backup matters here. The storms that put the Little Blue over its banks are the same storms that knock out power. The discharge goes outside, at least 5 feet from the house, and never into your sanitary sewer line.
The Person Who Bids Your Job Has Done the Work
Your estimate comes from John Murphy, who has 26 years in foundation repair: 21 installing and 5 in sales. When he walks your basement, he is already picturing the dig, where each pier goes, and what is in the way.
That experience saves real money. On one Olson job, the homeowner expected to pay to move their water heater so the repair could happen. John knew the work could be done around it, which spared them the cost and the disruption.
It also shapes what we recommend:
- We find the actual cause before we talk about fixes.
- We lay out your options, with prices, and explain what each one does.
- We recommend the work your house needs. Sometimes that means repairing the side that moved and watching how it performs, rather than proposing piers around the whole house.
Foundation Repair Cost in Grandview, MO
Most jobs across the metro land between $4,000 and $15,000. A single crack injection can be a few hundred dollars, and a full perimeter of piers can pass $25,000.
Repair | Our price |
Concentric push piers | $1,600 to $1,800 per pier |
Steel I-beams | $500 to $700 per beam |
Deadman anchors (tiebacks) | $1,100 to $1,300 per anchor |
Wall push | $325 to $375 per foot |
Wall rebuild | $90 to $120 per sq. ft. |
Epoxy crack injection | $40 to $50 per foot |
Interior drain tile | $75 to $90 per foot |
Sump pump with battery backup | $2,400 to $2,600 |
Buried downspouts | $30 to $40 per foot |
What moves your number:
- How long it has been moving. A wall braced this year costs less than the same wall rebuilt in three years.
- How many units. Four I-beams cost less than seven.
- Which side. On a split, fixing only the section that moved keeps the bill down.
- Access. A driveway or patio poured against the wall can steer you toward interior I-beams instead of anchors or a dig.
- Inside or outside. Excavation adds labor hours.

Picking Foundation Repair Contractors in Grandview

- Measurements, not guesses. Ask how far the wall has moved and where the floors are out of level. The numbers should drive the bid.
- An itemized, written bid you can line up against another one.
- A written warranty for each type of repair, explained before work starts.

Foundation Repair FAQs for Grandview Homeowners
Most jobs run $4,000 to $15,000, with push piers at $1,600 to $1,800 each and I-beams at $500 to $700 each. A crack injection can be a few hundred dollars. A free inspection is the only way to get a number for your house.
Yes, structural repairs are permitted through the City of Grandview at City Hall, 1200 Main Street. Your contractor should pull it as part of the job.
Usually, yes. A horizontal crack means soil is pushing the wall inward, which is common just below grade in raised ranches and split-entries. Have it measured soon, because bracing a wall early costs far less than rebuilding it.
That is usually a sewer backup, not a foundation leak. A plumber can install a backflow valve to stop it.
Often, yes. If only one wall or section moved, we can repair that side and watch how it performs. Piers around the whole house are not the default.
I-beams brace the wall from inside and need no digging, which helps when a driveway or patio sits against the house. Deadman anchors reach into the yard and need open space on that side. We recommend whichever fits your wall and your lot.
Usually not, since most policies exclude soil movement and settling. Damage from a sudden covered event, like a burst pipe washing out soil, is sometimes covered, so check with your agent.
Crack injections often take one day. Most pier, bracing, and drainage jobs take one to three days, and larger jobs or wall rebuilds can run a week or more. If we lift part of the house, wait a month or two before patching drywall.
Yes, in nearly every case. We ask you to move belongings 6 to 10 feet back from the walls we are working on, and the crew handles the rest.
Call if a crack is wider than 1/8 inch, keeps growing, or runs horizontally. Floors that drop more than 1 inch over 10 feet are also worth an inspection.
In most cases, yes. Buyers’ inspectors and lenders flag foundation issues, and a documented repair with a warranty reads far better than an open problem on the report.
