Drainage in London

Drainage problems rarely announce themselves politely. Slow gullies, recurring blockages and unexplained damp are usually symptoms of something further down the line — and guessing is expensive. GEM approaches drainage diagnostically: clear the immediate problem, then establish the cause.

Our teams carry out high-pressure water jetting and mechanical clearance for blockages, CCTV surveys to map the condition of runs beneath London's older properties, and no-dig lining or excavation repairs where the survey shows genuine defects. You receive the footage and a plain-English condition report, not just an invoice.

For portfolio clients we schedule preventative jetting on known problem runs, which is dramatically cheaper than the emergency alternative and keeps tenants out of the loop entirely.
