Common cctv drain surveys problems in Lewisham
- ✓ Pre-purchase surveys on New Cross and Deptford Victorian terraces, where root infiltration and displaced joints are common in pre-1920 clay drainage
- ✓ Sewer surcharge and slow-drainage investigations in low-lying streets near Deptford Creek, where the River Ravensbourne raises groundwater and back-pressure during storms
- ✓ Drain mapping for loft, basement and rear-extension work on Brockley and Forest Hill terraces, where original single drain runs were never designed for today's household loads
- ✓ Recurring blockage diagnosis in Sydenham properties near Mountsfield Park, where mature tree roots regularly re-enter jetted or rodded drains within months
- ✓ Thames Water boundary disputes on shared drain runs beneath New Cross and Deptford terrace rows, where responsibility for a single connecting pipe is often unclear
