What are the warning signs of a failing foundation?

Genuine warning signs include cracks that are widening over time (rather than fine, stable, cosmetic cracking), doors and windows that have started sticking or no longer close properly, visible sloping or unevenness in floors, and cracks that show a visible step or offset rather than a clean hairline.

One or two of these signs in isolation isn’t automatically cause for alarm, but a combination — or any sign that’s clearly progressing over time — genuinely warrants a professional assessment rather than waiting to see if it gets worse.

Catching a genuine foundation problem early is significantly less costly and disruptive than addressing it once it’s progressed further, which is exactly why these signs are worth taking seriously rather than dismissing as normal settling.
