Common cctv drain surveys problems in Lewisham
- ✓ Pre-purchase surveys on New Cross and Deptford terraces, where roots and displaced joints are common in older clay drains
- ✓ Slow-drainage checks in low-lying streets near Deptford Creek, where the Ravensbourne raises groundwater in storms
- ✓ Drain mapping for loft, basement and rear-extension work on Brockley and Forest Hill terraces, where original single runs were not built for modern loads
- ✓ Repeat blockage diagnosis in Sydenham near Mountsfield Park, where roots re-enter cleared drains within months
- ✓ Boundary questions on shared drain runs beneath New Cross and Deptford terraces, where responsibility for a connecting pipe is often unclear
