Can a foundation issue be caused by a neighbouring property's work?

Yes, genuinely possible — excavation, significant tree removal, or other substantial work on a neighbouring property can, in some circumstances, affect your own foundation’s soil conditions or stability.

This is exactly why excavation near a shared boundary needs proper professional assessment and technique, regardless of which property the work is happening on — protecting neighbouring structures is a genuine, real responsibility.

If you have specific concerns about how a neighbour’s planned work might affect your property, raising this directly and, if needed, seeking your own professional advice is a reasonable, proactive step.
