Short answer: yes, and it happens more often than people realise.
When drains block or leak, water has nowhere to go. It can sit against walls, seep into brickwork, or saturate the ground around your property, eventually showing up as damp patches, musty smells, or mould indoors 🏠💧
If you’re treating damp but the cause is underground, it won’t fully go away until the drainage issue is sorted.
