A gully that backs up every time it rains, a ground-floor toilet that gurgles, a basement that smells after heavy weather: London's older terraces and converted villas know these problems well. Drainage in London means working with old shared runs and tight access. We deal with the pipes, the chambers and the repairs that follow.

Emergency Drain Unblocking and Drain Clearance
A slow gully, a toilet that gurgles when the basin empties, a smell rising from the floor trap: in London's Victorian and Edwardian terraces these usually trace back to the same place. Old shared runs, many pipes feeding one line, and decades of grease, wipes and scale narrowing the bore. We clear the blockage first, then look at why it formed.
The sequence is plain. We find the point where the flow stops, usually at the nearest inspection chamber or gully. We clear it with rods or water, and we run clean water through to confirm the line drains freely. If the line fails that test, the problem is a defect rather than a blockage. That is a repair, and we say so before anything else is proposed.
Disruption is small at this stage. Most clearances happen at one access point, so the work stays outside or in a single bathroom or kitchen. Dust sheets go down, covers go back, and no room is lost for days.

Commercial and Industrial Drainage Services in London
Small businesses carry a different load. A kitchen drain takes fat. A shared stack in a converted villa or mansion block takes the waste of several flats at once. We work on both, as part of our cover for homes and small businesses across Greater London.
Basements need particular care. The Greater London Authority says basement plumbing should account for possible sewer flooding when drainage systems are overwhelmed. Kensington and Chelsea also requires pumped devices to protect against sewer flooding in basement work. So any drainage change below ground level has to respect those controls, and we plan it that way from the start.
- Shared stacks and waste pipes in mansion blocks and converted houses
- Kitchen and food-premises drain lines
- Basement drainage and pumped protection against backflow
- Gullies, traps and inspection chambers at the property boundary
Whether you need a drainage in London or a gas safety certificate in London, we cover the whole area. Landlords with a block often need both arranged together.
Clearing Grease, Scale and Silt
Pushing a blockage along is not clearing it. The deposit has to come out. Grease, scale and silt cling to the pipe wall rather than sit in a lump, so the way they are cleared follows the deposit.
The order matters for the pipe. Clay pipes in older streets and plastic pipes in newer ones tolerate different treatment, so the approach follows the pipe, not a habit.
Searching for drainage near you in Wandsworth, Clapham or Richmond usually means a tight street and a drain at the back of a terrace. Working from one chamber keeps the mess outside and the house clear. Our wider drainage services cover the pipes, gullies and chambers around the job, not only the blockage itself.
From London to City of Westminster, the same service is there when you need a drainage in City of Westminster. Near the Royal Parks, access can be tight, so we plan where the work happens before it begins.
Drain Repairs and Drain Replacement
A repair follows a diagnosis. If a line keeps blocking in the same place, the cause is often a cracked section, a displaced joint or a root entry, and clearing it again only buys time. We locate the fault, show you where it is, and describe the options in writing before any work starts.
The repair route runs in order:
- Locate and confirm the defect along the run
- Decide between a localised patch and replacing the length
- Excavate only the section that needs it, or use a no-dig method
- Reinstate the bedding and pipe, test the line, then backfill
Excavation is the part people dread, so it is kept narrow. We open the ground over the fault, not across the garden. Spoil is kept to one side, the trench is backfilled and the surface is made good. Wandsworth notes that many properties sit in flood-risk areas, and replacement near a basement needs the same care as a new build.
Repairing a Cracked Drain
Where a pipe is cracked but still in line, the repair can be smaller than a full dig. It suits cracked clay and joints that leak, under paths, patios and floors that you would rather not lift.
It is not right for every fault. A collapsed or badly displaced pipe has to be dug out, and we say so plainly.
Describe the job to us and you receive a written price before any work starts. Tell us what the drain is doing, and we will say whether it needs clearing or repair.

Drainage in London FAQs
How do I know if my property has surface water drainage?
Look for gullies, downpipes running to ground and grated channels on paths or drives. In many London terraces, rainwater shares a line with the foul drain. If you are unsure, we can trace where it goes and tell you.
What does a drainage specialist do?
We find why water is not leaving a property properly, then fix it. That means clearing blockages, jetting lines, repairing cracked pipes and lining or replacing sections. We describe the job first and give you a written price before work starts.
Does basement drainage in London need special care?
Yes. The Greater London Authority says basement plumbing should account for possible sewer flooding. Kensington and Chelsea requires pumped protection in basement work. We plan any below-ground drainage change with those controls in mind.
Will repairing a drain mean digging up my garden?
Not always. If a pipe is cracked but still in line, lining can work from two access points with no trench. If it has collapsed, we dig only the section that needs it. We say which before we start.
