Drainplumb has no review score to wave at you, and we will not invent one. What we can state is how a Drain Unblocking job in London starts: you describe the blockage at no charge, and a written price arrives before any work begins. Sink, toilet, gully or main run, the job starts with working out what is actually in the pipe.

- How we price a job: described at no charge, written price first
- When a blockage needs a drain survey and repair, not another clearance
- How older London terraces and shared pipework shape the clearing method
- What to do before you call us about a blocked drain

Blocked Drain Symptoms and Causes
A blocked drain rarely announces itself politely. The first sign is usually a sink that drains slowly, a toilet that gurgles when the bath empties, or a smell near a gully that was not there last week. Then the water stops going anywhere.
London makes this awkward. Victorian and Edwardian terraces, converted villas and mansion blocks often share runs of old pipework, so one blockage can show up in a flat or house that did not cause it. Interwar semis and post-war estates have their own habits. The pipe layout differs from street to street.
Most blockages are ordinary things that built up: grease and soap in kitchen and basin pipes, wipes and paper in toilet runs, leaves and silt in gullies. Sometimes the cause is the pipe itself, such as a collapsed section or roots pushing in. That is a different job, and we say so before any work starts.
- Slow or standing water in sinks, baths and showers
- Toilets that will not clear or bubble when other fittings drain
- Foul smells near gullies and inspection chambers
- Water backing up in a yard or beside the house
If you are searching for a blocked drain plumber near you in London, describe what you are seeing and we take it from there. A symptom tells us where to look. It does not tell us the cause yet.

Drain Unblocking Costs and Preventing Future Drain Blockages
Nobody wants a vague number for a drain job. So here is how it works with us. You describe the job at no charge. You receive a written price before any work starts. No price is quoted over the phone for a drain we have not understood.
The awkward part is repeat blockages. Clearing a pipe and ignoring why it filled is a short-term fix. If the cause is grease, wipes or leaf litter, the fix is a change of habit. If the cause is the pipe, clearing it again only buys time.
- Keep fat and oil out of kitchen sinks
- Bin wipes, cotton buds and sanitary items, never flush them
- Keep gully grates clear of leaves and silt
- Report slow drains early, before they stop
Basements need extra thought in London. The Greater London Authority says basement plumbing should allow for possible sewer flooding when drainage is overwhelmed. If your property has a basement, tell us when you call.
Repeat Blockages and Drain Repairs
Some blockages come back. That points to something in the pipe, not something that passed through it. A cracked section, a displaced joint or a bend that traps debris will keep catching things, however often it is cleared.
This is where clearance ends and repair begins. The repair should be based on what is wrong with the pipe rather than a guess. We will explain what we find and what it means for the job.
Repairs depend on the building. A shared run behind a terrace is not the same as a single pipe on a modern flat. Access matters too: dense streets and property near the Royal Parks can mean careful planning of how work reaches the drain. We describe that in the written price, before work begins.
Repair is not always needed. Plenty of drains only need clearing. We will tell you which one you have.
Drain Unblocking and Clearance
Clearance starts with finding the blockage, not with reaching for the biggest tool. We work out where it sits, whether it is in a sink waste, a toilet branch, a gully or the main run, and then clear it by a method that suits the pipe.
Old pipework is the worry here. A Victorian terrace or a converted villa can have fragile sections, and forcing a blockage through them does damage. So the method is chosen with the pipe in mind. That is the point of looking first.
Flats and mansion blocks add another question: whose pipe is it? A blockage in your own branch is yours to sort. One further down a shared run may not be. We help you work out where the problem sits, so you know where you stand.
Blocked sinks, toilets, gullies and drains all come under this one job. The pipes differ. The approach does not.
