Spreading cracks in a hallway
End-of-terrace house, Durham- The concern
- Diagonal cracks in the hallway, up to about 5mm wide, had been spreading and widening for over two years. The owner had started marking them but didn't know what was causing them.
- What we found
- Settlement of the front corner of the house. The most likely cause was a downpipe discharging roof water straight onto the ground beside the foundations, with a newly built raised driveway making it worse.
- Outcome
- Low-cost immediate fixes: take the downpipe into a sealed gully and clear the base of the wall. Crack monitoring and a trial pit will confirm the cause before any repair is designed, so nothing is spent on work that isn't needed.
