Drainage Unblocking London

Emergency drainage unblocking and drainage clearance

Blocked drainage rarely stays a small problem. Water backing up in a gully, a manhole lid lifting or toilets filling slowly are signs that the whole run is holding water, and the next heavy rainfall or full dishwasher can push it into the property. Our drainage unblocking service is available 24 hours a day across London and the M25. We locate the blockage by lifting the nearest manholes, then choose rods, a high-pressure jetter or a root cutter for what is actually in the pipe. Drainage clearance is not finished until water flows freely from every appliance on that run, which we test before we leave. We then put a camera through the cleared section so you can see whether the cause was a one-off build-up of fat and wipes or a cracked, displaced or root-damaged pipe that will block again. Commercial kitchens, offices, schools and managed blocks get priority emergency drainage unblocking, because a blocked washroom or kitchen drain can close a business for the day. Domestic drain unblocking is charged at £120+VAT for the first hour, commercial at £150+VAT, and any further work such as a CCTV survey report, patch lining or excavation is quoted before it starts.

• Emergency drainage unblocking 24 hours a day
• Blocked drainage traced manhole by manhole
• Jetting, rodding and root cutting matched to the blockage
• Flow test and camera check after every drainage clearance

Common causes of a blocked drain

Domestic blockages are usually wet wipes, sanitary products, cooking fat poured down a kitchen sink, or a build-up of soap scale and hair. Outside, the usual culprits are leaves and silt in a gully, tree roots that have found a cracked joint, or a bedding fault causing solids to settle. Commercial kitchens block almost exclusively because of fats, oils and grease. Identifying the cause matters, because the cure is different for each.

How we clear the blockage

We lift the nearest manhole covers to find where the run is holding water, which isolates the blocked section quickly. Rods clear simple obstructions; a high-pressure jetting hose with the correct nozzle scours the pipe wall clean of fat and scale; a root-cutting head removes ingress. Once the flow is restored we run water from the property to confirm the whole line is clear.

• Manhole inspection to isolate the blocked section
• Jetting or rodding, chosen for the type of blockage
• Flow test from every appliance served by the run
• Camera check to identify any underlying defect

Recurring blockages

If a drain blocks more than once in a year, something structural is usually wrong: a displaced joint catching debris, a section with insufficient fall, or roots re-growing through a crack. We include a camera check after clearing, and if a defect is found we quote for a permanent no-dig repair rather than selling you a repeat clearance visit every few months.

Preventing the next one

Simple habits stop most repeat call-outs. Never pour cooking fat down the sink — let it set and bin it. Fit a strainer to shower and bath wastes to catch hair. Bin wipes, cotton buds and sanitary products rather than flushing them. Clear leaves from external gullies each autumn. Commercial kitchens should run a planned jetting schedule and service grease traps regularly.
