Foundation Repair in Raymore, MO

Nearly half of Raymore’s homes were built after 2000, yet newer houses still crack, stick, and leak. Swelling clay, settling backfill, and new construction all change how water hits your walls, and Olson has handled it since 1986. Our foundation repair in Raymore, MO starts outside, with your grade and drainage, so you only pay for the repair your house actually needs. The inspection is free, and if your foundation is fine, we’ll tell you.

Why Newer Raymore Homes Still Crack and Leak

Raymore was open prairie before it was subdivisions. The topsoil is rich, but underneath is heavy clay over shale that swells when it’s wet, shrinks when it dries, and drains slowly. Add how most of town was built, and these are the problems we see most:

  • Backfill that keeps settling. The soil pushed back against your walls during construction is looser than undisturbed ground. As it settles, the yard can flatten out or tilt toward the house.
  • Blocked lot-line swales. Raymore’s code treats the strip between two houses as a drainage path. A fence, landscape bed, or shed in that swale can send water to your wall instead of past it.
  • Downspouts and sump lines that dump too close. Water that lands at the foundation soaks the clay right where your walls need it dry.
  • Walkout basements. The buried wall opposite a walkout carries the soil pressure, and the open side gives it nothing to push back against.
  • Runoff from new building. The spring 2026 storms sent creek water through yards along Good Parkway that sit outside any floodplain, and the city closed Dean Avenue at Johnston Drive for flooding.
  • Dry spells, then downpours. Fall 2025 was dry across the south metro, and April 2026 brought heavy rain. That swing is exactly what makes clay move.

None of this means your builder cut corners. It means the ground and the water around your house keep changing, and your foundation feels it.

What Good Foundation Repair Contractors Check First

A crack tells you something moved. It doesn’t tell you why. Before we recommend anything, a foundation inspection from Olson covers:

  • Your grade. The residential code calls for 6 inches of fall in the first 10 feet away from the house. On tight Raymore lots where that won’t fit, a swale or drain has to carry the water off instead.
  • Where the water goes. Downspouts, the swale between houses, your sump discharge, and whether a neighbor’s yard drains toward yours.
  • Which way the crack runs. Horizontal cracks usually mean soil pushing a wall in. Diagonal cracks from corners, doors, and windows usually point to settling. A thin vertical crack is often just concrete shrinkage.
  • Whether it’s still moving. A crack that opened years ago and stopped is a different job from one that’s growing. Pencil-mark both ends with the date, and we can compare.
  • How far a wall has moved. We measure how far it leans or bows in, not just whether it does.
  • Floors, doors and windows. Where the house is out of level, and by how much.

If one side has settled, it can make sense to repair that side and see how the house performs before doing more. And sometimes the honest answer is better drainage and gutters, not piers.

Piers for Settling, Bracing for Pushing Walls

Settling and wall pressure look similar to most people, but they need opposite fixes. Here’s how we tell them apart.

What you’re seeing What’s usually happening Typical fix
Sloping floors, a dropped corner, diagonal cracks at doors, doors that stick Soil under the footing can’t carry the load Concentric steel piers
Horizontal crack, a wall leaning or bowing in Wet clay pushing the wall sideways Steel I-beams or deadman anchors
Water at the base of the wall, damp corners Water collecting at the footing Drainage first, then drain tile and a sump
Sunken driveway, patio or garage slab Soil washed out or compacted under the slab Polyjacking

Concentric Push Piers for House Foundation Repair

When part of the house has dropped, piers carry its weight past the active clay to solid ground.

  • We dig beside the footing at each pier location and set a steel bracket centered under the wall.
  • A hydraulic ram uses the weight of your house to drive steel sections down to bedrock or weathered shale, typically 22 to 70 feet.
  • Every pier is load-tested as it goes in. Then the house is lifted in sequence and locked in place.
  • Spacing runs about 5 to 7 feet on poured walls and 4 to 5 feet on block.

Porches, slabs, and additions with no real footing usually get helical piers instead. More on foundation piering.

Bowing Basement Wall Repair With Steel Beams or Anchors

When wet clay is pushing a wall in, the fix holds the wall where it is.

  • Under about 3 inches of movement: 4-inch steel I-beams set on the footing and fastened to the floor joists, about every 4 feet on block and up to 6 feet on poured walls. In a finished basement, we open about a foot of ceiling drywall at each beam.
  • Walkouts and homes below a slope: deadman anchors. A concrete anchor buried in the yard is tied through the wall with a steel rod.
  • 3 to 4 inches or more: the wall is pushed back to plumb from outside or rebuilt.

If a crack goes through the wall, foundation crack repair with epoxy injection seals it, but only after the movement is stopped. See wall bracing for more detail.

When Water Is the Real Problem

In our experience, 90 to 95% of basement water problems come from drainage or gutters. Often the first step is extending or burying downspouts and fixing the grade. When water still reaches the footing, basement waterproofing with interior drain tile and a sump pump catches it, and a battery backup keeps the pump running when a storm knocks the power out.

Raymore has its own rules for where that water can go:

  • Never into the sanitary sewer.
  • No closer than 5 feet to a neighbor’s property line.
  • A line run to the curb must be disconnected 5 feet back from the street right-of-way from November 1 to April 1.

What Installation and Cleanup Look Like

Here’s what actually happens at your house, so nothing on install day is a surprise.

Pier jobs (outside)

  • We dig a small hole beside the footing at each pier spot, clear soil from under the footing and chip the concrete smooth for the bracket.
  • Steel sections are driven down, each pier is load-tested, and the house is lifted in sequence and locked in place.
  • Soil goes back in and is compacted, and any concrete and landscaping we dug through are put back.
  • On tight Raymore side yards or walkout slopes, we plan digs and equipment paths around fences and grade before day one.

Wall bracing (inside)

  • We break out a small section of basement floor at each beam and set the beam on the footing, checked for level and plumb.
  • The top is bolted to the floor joists, the gap behind the beam is grouted, and the floor is re-poured around the base.
  • No digging in your yard. In a finished basement, we open about a foot of ceiling drywall at each beam.

Drain tile and sump (inside)

  • We cut a trench 12 to 16 inches from the wall, lay perforated pipe in gravel, and re-pour the floor. Most jobs take 1 to 3 days.

Living through it

  • Clear belongings 6 to 10 feet back from the walls we’re working on. Most families stay home the whole time.
  • After a lift, give the house a month or two before patching drywall cracks.

Who Handles Foundation Repair Permits in Raymore

Raymore runs its own building department, so the city, not Cass County or Kansas City, permits structural work.

  • The office: City of Raymore Building Inspections, 100 Municipal Circle, (816) 331-7916.
  • The code: Raymore builds and repairs under the 2018 International Codes, including the code for existing buildings.
  • The contractor: Anyone pulling a permit needs a Raymore contractor license. Class C covers residential work, so ask every bidder if they hold one.
  • Drainage work: Tying a sump or drain line into a city storm sewer inlet needs its own permit.

We’ll tell you which permits your job needs before work starts.

Foundation Repair Cost in Raymore, MO

Nobody can price your house from a website, but you deserve real numbers. Most foundation jobs across the metro land between $4,000 and $15,000. Here’s what we charge for the work Raymore homes need most:

Repair Our pricing
Concentric steel piers $1,600 to $1,800 per pier
Helical piers $1,950 to $2,450 per pier
Steel I-beams (wall bracing) $500 to $700 per beam
Deadman anchors $1,100 to $1,300 per anchor
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
Burying downspouts $30 to $40 per foot

What moves your number:

  • How many units. Six piers cost more than three.
  • Access. A tight side yard, a fence on the lot line or a walkout slope adds labor.
  • Inside or outside. Exterior work means digging, and digging takes longer.
  • How long it waits. A crack handled this year costs less than the same crack in three years.

Warranty by repair: lifetime and transferable on qualifying concentric pier systems; 15 years on wall anchors, I-beams and drain tile; 5 years on sump pumps and waterproofing membrane; 3 years on adjustable posts. See warranty details.

FAQs About Foundation Repair in Raymore, MO

Most metro jobs run $4,000 to $15,000, with concentric steel piers at $1,600 to $1,800 each and steel I-beams at $500 to $700 each. Your total depends on how many units the house needs and how easy the work area is to reach.

Yes. The soil packed against a new foundation keeps settling for years, which can flatten the grade and send water back toward the walls. Clay that swells and shrinks doesn’t care how old the house is.

It depends on the direction and whether it’s still growing. Horizontal cracks usually mean wall pressure, and diagonal cracks from corners usually mean settling. A thin vertical crack is often just concrete shrinkage.

Not always. If one side has settled, it can make sense to pier that side and see how the house performs before doing more.

Not into the sanitary sewer, and not within 5 feet of a neighbor’s property line. A line run to the curb has to be disconnected 5 feet back from the right-of-way from November 1 to April 1.

The residential code calls for 6 inches of fall in the first 10 feet. Where a tight lot won’t allow that, a swale or drain has to carry the water away instead.

In most cases, yes. Pier work happens at the footing and bracing happens in the basement, so you mainly need to clear belongings 6 to 10 feet back from the work walls.

Usually not, because most policies exclude settling and soil movement. Damage from a sudden covered event, like a burst pipe, may be covered, so check with your agent.
