What are the common signs that my concrete foundation needs repair?

Here are the most common signs that your concrete foundation may need repair:

• Hairline cracks may be normal from curing, but wider cracks (especially diagonal or stair-step) often indicate movement.
• Cracks in tile, concrete floors, or exterior brickwork can also be red flags.

• If floors slope noticeably or feel soft in spots, it may mean part of the slab has settled.

• When the foundation shifts, door and window frames twist, making them hard to open or close.

• Spaces between doors/windows and their frames or between crown molding and ceilings can signal movement.

• Mortar joints pulling apart or siding separating from corners indicate shifting below.

• Persistent moisture can weaken the soil and lead to uneven settling.

• Pressure from soil movement can cause foundation walls to bulge inward.

💡 Pro Tip for Houston Homeowners:
Because the city’s expansive clay soil swells and shrinks with moisture changes, even small warning signs should be inspected early to avoid bigger, costlier repairs.
