The short answer
Look for Cracks and Gaps
Cracks are the most obvious sign of foundation settling. Check interior walls, especially around doorframes and window corners, for new or widening cracks. Hairline cracks may be cosmetic, but cracks wider than a quarter-inch or that step along brick or block walls deserve attention. Also inspect exterior foundation walls for vertical or diagonal cracks.
Gaps can appear where walls meet ceilings or floors, and around window and door frames. You might notice a visible separation between the baseboard and the floor, or between the ceiling and the top of a wall. These gaps often indicate that different parts of the house are moving at different rates. Measure any gap and note the date to track changes over time.
Check Doors and Windows
Sticking doors and windows are a classic clue. If a door that used to close easily now scrapes the floor or jamb, the frame may have shifted. Windows that suddenly stick or have visible gaps along the edges can signal movement. Open and close a few doors and windows in different rooms to see if the problem is widespread.
You can also check for uneven gaps around a door or window. Slide a piece of paper along the frame; if it catches in some spots and slides freely in others, the frame may no longer be square. This unevenness can come from foundation settling, but it can also be caused by humidity or seasonal changes. Track the issue over several months to see if it worsens.
- Use a level to check floors and window sills
- Measure cracks with a ruler and note the date
- Look for gaps between the foundation and the soil
- Check for doors that stick or scrape the floor
- Inspect for separation between the chimney and the house
Measure Sloping Floors
Place a marble or a golf ball on a flat floor. If it rolls slowly toward one side, the floor may be sloping. Use a carpenter's level to check for a consistent tilt. A slope of more than an inch over 10 feet can be a sign of significant settling, though some slope is normal in older homes.
Sloping floors can also be caused by moisture-related issues, such as a leaking pipe or poor drainage around the foundation. If you notice a slope, check for water stains or musty smells in the area. Heavy rain or seasonal changes can saturate the soil and affect foundations. A water damage inspection can help identify if moisture is a factor.
Watch for Exterior Signs
Outside your home, inspect the foundation for cracks, bowing, or areas where the soil has pulled away. Check the roofline for sagging or wavy sections, which can indicate that the foundation is uneven. Look at the siding or brick for gaps that open and close with the seasons.
Also check your gutters and downspouts. Water pooling near the foundation can worsen settling. Make sure downspouts direct water at least a few feet away from the house. If you see erosion or standing water, improving drainage might help. For a thorough evaluation, the pros can perform moisture mapping to see where water is entering.
Track Changes over Time
Foundation settling often happens slowly. A single crack may not mean a serious problem, but a crack that widens or new cracks appearing over months is a warning. Keep a simple log: take photos, measure crack widths, and note the date. This record helps you see the rate of movement and can be useful if you talk to a professional.
If you suspect settling, do not ignore it. Early detection can prevent more extensive damage to your home's structure and your belongings. Contact the pros for a water damage inspection and foundation stabilization assessment. They can help determine the cause and recommend steps to protect your home. Policies vary, and your insurer decides what is covered.
- Take photos of cracks and gaps each season
- Measure door and window gaps with a feeler gauge
- Note any new cracks or changes in existing ones
- Check for changes in how doors and windows operate
- Keep a record of any water stains or musty odors

What causes foundation settling?
Foundation settling often results from soil movement, such as expansive clay that swells when wet and shrinks when dry. Poor drainage, leaky pipes, or tree roots can also contribute. In humid climates with heavy rains, the soil can shift. A water damage inspection can help identify moisture issues.
How can I tell if a crack is serious?
Look at the width and pattern. Cracks wider than a quarter-inch, or that are stepped along brick, are more concerning. Also check if the crack is active, meaning it grows or changes. Measure it over time. If it worsens, consult the pros for a foundation stabilization assessment.
Can I fix foundation settling myself?
Minor cosmetic cracks can be patched, but structural settling usually requires professional help. DIY fixes may hide the problem without addressing the cause. A professional can evaluate the soil, drainage, and foundation. If you notice significant movement, contact the pros for a water damage inspection.
