Common cctv drain surveys problems in Lambeth
- ✓ Pre-purchase surveys on Brixton and Stockwell terraces, where old clay drains near the Effra may suffer joint movement
- ✓ Root checks for homes beside Clapham Common and Brockwell Park, where tree roots often cause repeat blockages
- ✓ Repeat blockage call-outs in Streatham and Tulse Hill, where rodding gives short relief and the cause is often roots or a cracked joint
- ✓ Drain mapping for basement conversions and extensions on Herne Hill and West Norwood villas, before groundworks start
- ✓ Evidence for insurance claims on drain failures and subsidence near the Effra corridor
