Quick, low-risk steps
- Record changes by date instead of deciding from one crack.
- Photograph from the same safe position with a reference scale.
- Note sticking doors, uneven floors, leaks, and recent weather.
- Separate an independent engineering opinion from a repair bid.
- Compare quantities, engineering, restoration, and warranty terms.
Common Causes Beyond Foundation Movement
Sticking doors and windows are often caused by seasonal humidity changes that make wood swell or shrink. In the Dallas–Fort Worth area, expansive clay soils can also cause minor seasonal movement that affects door and window frames. These issues may be normal and not a sign of structural damage.
Uneven floors can result from sagging floor joists, improper original construction, or settling of interior supports. Before assuming foundation trouble, check for simpler explanations like loose hinges, paint buildup, or worn weatherstripping.
- Wood expands in humid months and contracts in dry months.
- Expansive clay soils can cause minor seasonal movement.
- Sagging floor joists or support posts can make floors uneven.
- Loose hinges or paint buildup can cause sticking doors.
- Worn weatherstripping can make windows hard to open.
When to Suspect Foundation Movement
Foundation movement may be a factor if you notice multiple signs appearing together, such as cracks in walls or brick, gaps around windows or doors, and sloping floors. The USDA notes that soil conditions can affect structures, but only a qualified professional can evaluate your specific property.
The USGS emphasizes that evaluating a specific building requires an on-site inspection by a qualified professional. Do not rely on general soil maps or online guides to diagnose your home's condition.
- Look for multiple signs: cracks, gaps, and sloping floors.
- Soil conditions can affect structures, but each home is unique.
- Only a qualified professional can evaluate your specific property.
- General soil maps are not a substitute for an on-site inspection.
- Document changes over time to share with an engineer.
Safe Steps to Take Before Calling a Pro
Start a simple log to track when doors or windows stick and whether it changes with the weather. Use a level to check floors in several rooms, and photograph any cracks with a coin or ruler for scale. This information helps an engineer understand patterns.
Avoid making adjustments like planing doors or shimming windows until you know the cause. Temporary fixes can hide important clues and may not solve the underlying issue.
- Keep a log of sticking doors and windows with dates and weather.
- Use a level to check floors in multiple rooms.
- Photograph cracks with a reference scale from the same position.
- Do not plane doors or shim windows before an evaluation.
- Share your log and photos with an independent engineer.
Getting an Independent Evaluation
A Texas-licensed structural engineer can assess whether the movement is ongoing, stable, or cosmetic. They will measure elevations, check for plumbing leaks, and review the foundation type and soil conditions. This independent opinion is separate from a repair contractor's bid.
When comparing repair proposals, look for detailed quantities, engineering justification, permit and inspection plans, and warranty terms. Use a quote comparer tool to line up scope items side by side.
- Hire a Texas-licensed structural engineer for an independent opinion.
- Expect elevation measurements and a plumbing leak test.
- Keep the engineering report separate from repair bids.
- Compare proposals on quantities, engineering, and restoration.
- Check warranty ownership and transfer terms.

Common questions
What homeowners ask next
Can sticking doors mean my foundation is failing?
Not necessarily. Sticking doors can be caused by humidity, loose hinges, or normal settling. Only a professional evaluation can determine if foundation movement is the cause.
Should I fix uneven floors myself?
Do not attempt to level floors yourself. Uneven floors can have many causes, and DIY fixes may hide serious structural issues. Get an independent engineering opinion first.
How do I know if movement is active or old?
An engineer can use crack monitors, elevation surveys, and other tools to determine if movement is ongoing. Homeowner logs and dated photos are helpful evidence.
