Warning Signs Your Foundation May Need Repair | Ryan Sturman
Our team walks through this on camera.
Every foundation repair warning sign we diagnose.
Click any sign for what causes it and how we diagnose it.
Bouncing Floors
A floor that flexes or bounces when you walk across it. This points to lost support underneath, often from foundation settlement or sagging structural members. The bounce gets worse as the support keeps shifting.
Learn more
Bowing Walls
Inward deflection in a basement wall. Even a fraction of an inch. Indicates lateral soil pressure exceeding the wall's capacity. The pressure doesn't go away; it compounds season by season until the wall requires reinforcement or replacement.
Learn more
Carpenter Ant Infestation
Carpenter ants do not eat wood, they nest in it. They look for wood that is already damp or softened. Their presence is often a sign that a crawl space or foundation area is holding water it should not.
Learn more
Ceiling Gaps
A crack or gap where the wall meets the ceiling. This means part of the structure is moving differently than the rest. The separation usually traces back to foundation movement below.
Learn more
Cracked Block Foundation
A cracked block foundation is rarely random. The direction of the crack, whether stair-step, vertical, or horizontal, points to the force behind it. Reading that pattern early decides how hard the repair will be.
Learn more
Cracked Brick Veneer Diagnosed and Stabilized
Epp Foundation Repair has read brick veneer crack patterns across Nebraska, Iowa, Kansas, and Missouri since 1994. Most stair-step cracks are not a brick problem; they are a foundation problem the brick is reporting.
Learn more
Cracks in Door Frames, Ceilings, and Corners
Cracks tend to appear where a structure is weakest, at door corners, ceiling-to-wall joints, and room corners. When several show up together and keep growing, the foundation below is often the reason.
Learn more
Cracks in Floor Tiles and Grout
Tile is rigid and unforgiving. When it cracks in a line across a room, or grout keeps splitting along the same joints, the slab or subfloor beneath is often shifting and the tile is simply showing it.
Learn more
Detached Cabinets
When upper cabinets start separating from the wall or the ceiling, the wall behind them has often moved. A gap that grows over time is a sign the structure is shifting, not just that the cabinets loosened.
Learn more
Diagonal Cracks
A crack that runs at an angle, often from the corner of a door, window, or wall, is rarely random. The angle traces the path of stress as one part of a structure pulls away from another, and that usually means the foundation has moved.
Learn more
Doors Not Latching
A door that suddenly won't catch in its strike plate usually means the frame around it is no longer square. When several doors do this at once, the cause is often below your feet, in a foundation that has shifted.
Learn more
Doors and Windows Misaligned
When openings that used to operate cleanly start sticking, gapping, or refusing to close, the walls around them have shifted. Foundation movement is one of the most common reasons several openings drift out of alignment at the same time.
Learn more
Drywall Cracks Diagnosed at the Foundation, Not the Patch
Epp Foundation Repair has diagnosed drywall cracks across Nebraska, Iowa, Kansas, and Missouri since 1994. A crack that keeps coming back after the third patch is not a drywall problem; it is a foundation problem the wall is reporting.
Learn more
Drywall Nail Pops
A nail or screw head pushing a small bump or crack through the drywall. Most are caused by ordinary wood movement. A few are an early hint that the structure behind the wall is shifting.
Learn more
Expansive Soil
Much of Nebraska, Iowa, Kansas, and Missouri sits on clay-rich and loess soils that swell when they soak up water and shrink when they dry out. That cycle lifts and drops your foundation a little at a time, and the cracks you see are the record of it.
Learn more
Flood Damage
Flooding does its worst work after it drains. Saturated soil keeps pushing on the foundation, washed-out soil leaves footings unsupported, and the structure can shift for weeks afterward. The visible water is only the start.
Learn more
Flood Vents Failing
Flood vents are meant to let rising water pass through a crawl space or garage so pressure does not build against the walls. When they clog, stick shut, or fail, water gets trapped and the foundation takes the load.
Learn more
Concrete Floor Cracks Diagnosed by Cause, Not by Width Alone
Epp Foundation Repair has read concrete floor cracks across Nebraska, Iowa, Kansas, and Missouri since 1994. Crack width alone never tells the whole story; the pattern, the location, and the movement history do.
Learn more
Foundation Upheaval
Upheaval is the opposite of settlement. Instead of sinking, a section of slab or footing lifts upward. The cause is almost always expanding soil or trapped moisture below the foundation, and it usually gets worse during wet seasons.
Learn more
Gaps Around Windows and Doors
Epp Foundation Repair has diagnosed window and door gaps across Nebraska, Iowa, Kansas, and Missouri since 1994. BBB A+. BBB Integrity Award 2011 and 2016.
Learn more
Improper Drainage
When water pools or drains toward the house instead of away, it saturates the soil around the foundation. That saturated soil swells, shifts, and pushes on the structure. Over time it shows up as cracks, seepage, and movement.
Learn more
Large Cracks from Shifting or Water Pressure
A wide foundation crack is not just a bigger hairline. Width and pattern reveal whether soil shifting or water pressure is driving the problem, and either one tends to get worse with each wet season.
Learn more
Leaning Chimneys
Epp Foundation Repair has stabilized leaning chimneys across Nebraska, Iowa, Kansas, and Missouri since 1994. BBB A+. BBB Integrity Award 2011 and 2016.
Learn more
Rotten Wood
Epp Foundation Repair finds rotten wood at sill plates, rim joists, and support posts during inspections across Nebraska, Iowa, Kansas, and Missouri, and treats it as a sign to look at what is keeping that wood wet.
Learn more
Sagging Floors
Epp Foundation Repair has diagnosed and repaired sagging floors across Nebraska, Iowa, Kansas, and Missouri since 1994. BBB A+. BBB Integrity Award 2011 and 2016.
Learn more
Sagging Lintel Above Garage Door
The horizontal beam above your garage door has dipped, cracked, or pulled away from the wall. That beam carries real weight. A visible sag means the load above it is no longer fully supported, and the cause often sits in the footing or the ground below.
Learn more
Sinking Foundation
Epp Foundation Repair has stabilized sinking foundations across Nebraska, Iowa, Kansas, and Missouri since 1994. Starting with what's actually moving underneath, not a sales sheet of piers.
Learn more
Stair-Step Cracks
Epp Foundation Repair has measured, monitored, and repaired stair-step cracks across Nebraska, Iowa, Kansas, and Missouri since 1994, separating the active ones that need underpinning from the stable ones that just need sealing.
Learn more
Sticking Doors and Windows
Epp Foundation Repair has diagnosed sticking doors and windows across Nebraska, Iowa, Kansas, and Missouri since 1994. Starting with a seasonal-pattern test that tells homeowners whether they need underpinning or just a window contractor.
Learn more
Uneven Floors
Floors that slope, bounce, or have developed a visible dip are a structural symptom. Not a flooring problem. Most cases trace to foundation settlement, crawl space movement, or deteriorated framing beneath the finished floor.
