Blocked Drains in Tooting
The first honest question about a blocked drain is not how to clear it but whose it is. [Honest Plumber Tooting](/) answers on 07861 936716 at any hour, and the independently owned drainage company we send is asked to work out where the blockage sits before charging you to clear a pipe that the water company should be dealing with.
Published London guides put clearing a blocked drain at about £175 for a typical two-to-three-hour job, a blocked toilet at around the same, and a CCTV drain survey at £90 to £250 as a diagnosis on top. These are other sources' ranges, not our quotes. The company confirms its own price in writing, and you can turn it down once you have heard it.
Tooting's drains are old and busy. The terraces around Tooting Broadway and Upper Tooting Road were laid with Victorian clay pipes, many streets share a run between houses, and the Falcon Brook is culverted under Ritherdon Road in Balham as part of the local sewers. In July 2021 local video showed sewage drains overflowing near Tooting Town Hall after a storm.
That history explains a lot of call-outs. A gully that backs up in a downpour may be a sewer under strain rather than anything you did, while a toilet that gurgles every week is more likely a damaged or rooted pipe than bad luck. We would rather you knew which before spending money.

What We Can Help With
Blockages We Sort Out
Where the blockage sits decides the method, the price and who pays.

Toilets, Sinks and Showers
When one fixture is slow, the trap or the short waste pipe is usually the culprit: fat in a kitchen sink, hair in a shower, wipes in a toilet. The company clears it with a plunger, auger or rods and tells you what caused it, so you are not paying for the same visit twice.

Household Drains and Gullies
When the bath, basin and toilet all struggle together, or a yard gully fills, the blockage is further along. Rodding clears most, high-pressure jetting scours grease and scale, and a camera survey confirms cracks or roots that clearing alone will not cure.

Shared Drains and Public Sewers
In a converted flat or a terrace sharing one run, the problem can sit past your own boundary. Shared drains and lateral drains outside the boundary have belonged to the water company since October 2011, so we tell you when to report to Thames Water instead of paying for it.
Benefits for You
How We Keep It Honest
Three habits that stop a drain job turning into an argument.
Locate Before You Clear
The company checks which fixtures are affected, opens the nearest access point and works out roughly where the blockage sits. You hear the diagnosis and the price in writing before any rodding starts.
Say Who Owns It
If the blockage is in a shared or public sewer, you are told, and that can save the entire call-out. Where it is yours, the company clears the section on your side and explains what it found.
Prove It Is Clear
Clearing is followed by a flow test, and a camera run if the drain has failed before. If the pipe is damaged, a repair is quoted separately so you can decide, not guessed at in advance.
Tips & Advice
Warning Signs and Bad Habits
Most blockages announce themselves a few weeks early.
Signs a Drain Is Struggling
Act on these and the fix is usually smaller.
- A bath or basin that empties more slowly than it used to
- Gurgling from a toilet when the washing machine drains
- A smell at a gully, manhole or the bathroom floor
- Water standing in a yard gully after rain
- Damp patches or sunken paving along the line of a pipe
What Should Never Go Down
The usual suspects in homes around here.
- Cooking fat, oil and grease from the pan
- Wet wipes, even ones labelled flushable
- Cotton buds, sanitary products and nappies
- Food scraps and coffee grounds
- Loose hair with no strainer in the plughole
Why Use Us
Drains Across SW17, SW12 and SW16
Local ground, local causes.
Tooting: Victorian Clay and Storm Strain
Older terraces and Totterdown Fields cottages (1901 to 1911) sit on pipes that crack and shift, and the town hall flooding in July 2021 shows how fast the sewers fill. Backing-up after a downpour is a real local pattern.
Balham and the Heaver Estate
The culverted Falcon Brook under Ritherdon Road runs into the local drainage network. Mature avenue trees on the Heaver Estate can drop leaves into gullies, and mansion blocks such as Du Cane Court share vertical stacks. See Balham.
Tooting Bec and Furzedown
Streets facing Tooting Bec Common have tall trees whose roots can reach old joints, while Furzedown's Edwardian and interwar roads often share drains between pairs of houses.
A blocked drain is often one part of a wider water problem, so also see emergency plumbing and leak detection & repair. Browse everything on our services page, or read how we work to see why a local partner company attends.
What a Blocked Drain Really Is
A drain carries waste from fixtures to the public sewer, and a blockage can sit in a single trap, in the pipe serving the whole house, or in a shared run or public sewer. Each is cleared differently and each can have a different owner, which is why we ask where the water is backing up before we ask anything else.
Drainage work in England follows Building Regulations Part H, which sets falls, access points and materials. In Tooting, many Victorian and Edwardian pipes are clay with cement joints that crack as the ground moves, so a repeat blockage is as often a failing pipe as careless habits.
What Moves the Price of Drain Work
Method and Access
Rodding one fixture costs less than jetting a household drain, and a camera survey is priced on top. Access matters too: a manhole in a front garden is quick, while a drain under a flat's rear yard or a controlled-parking street adds time.
Who Owns the Pipe
If the blockage is in a shared sewer, the water company is responsible and the company tells you so rather than billing you. That honest answer can save the whole call-out.
Drains by Property Type
Terraces and Cottages
Victorian terraces off Upper Tooting Road and the Totterdown Fields cottages often send two or three houses' waste into one run. A blockage at the back of one house can therefore show up in the next, and the company checks both before deciding where to work.
Flats and Mansion Blocks
Du Cane Court has 676 flats and many Balham conversions share vertical stacks. If your neighbours' sinks gurgle too, the fault is above or below you, and the managing agent needs to know. We would rather send you the right instruction than a bill for a pipe you do not own.
Houses on the Commons
Homes beside Tooting Bec Common and Wandsworth Common sit among mature trees. Root growth and leaf fall are plausible causes of repeat blockages there, so a camera run after the second clearance is a sensible, honest suggestion.
Keeping the Paperwork Straight
If the company finds the blockage is in a shared or public sewer, ask for the finding in writing and keep it. It is what Thames Water or a freeholder will ask for when you report the problem, and it protects you from paying for work that was never yours to fund.
Your Questions Answered
How much does it cost to clear a blocked drain in Tooting?
Published London guides put a typical blocked-drain job at about £175 for two to three hours of labour, with a camera survey at £90 to £250 if diagnosis is needed. Those are ranges from other sources, not our quotes. The partner company inspects, then gives you a written price before it starts, and a simple fixture blockage costs less than a full jetting job.
How do I know whether the blockage is mine or Thames Water's?
Roughly, the drain that serves only your property up to the boundary is yours, while shared drains and the sewer beyond have belonged to the water company since October 2011. The partner company works out where the blockage sits before charging you to clear it. If it is Thames Water's, we tell you to report it to them instead.
Why does my toilet gurgle when the washing machine runs?
Gurgling usually means air is being pulled through a water seal because the drain is partly blocked further along, or a vent is restricted. It is an early warning, and clearing it now costs less than waiting for a full backup. If it comes with slow draining or a smell, ring us before the toilet overflows.
My drain backed up after a storm. Is that something I did?
Probably not. Local video from July 2021 showed sewage drains overflowing near Tooting Town Hall, and when public sewers fill, water can push back up through low gullies and ground-floor toilets. The partner company can clear and check your side, but the sewer itself belongs to Thames Water, so report it to them as well.
Can tree roots block a drain here?
Yes, particularly where tall trees stand near older pipes. Streets facing Tooting Bec Common and the avenue trees on the Heaver Estate are the obvious places, and clay joints that have moved let fine roots in. Jetting can cut them back, but a camera survey will show whether the pipe needs relining or repair to stop it returning.
Do I need a CCTV survey for every blocked drain?
No. A one-off blocked sink or toilet rarely needs one. A survey earns its keep when a drain blocks repeatedly, when roots or collapse are suspected, or when you are buying a property. The camera shows the pipe's condition and the exact position of a fault, so nobody digs in the wrong place. It is quoted separately so you can choose.
What is the difference between rodding and jetting?
Rodding pushes flexible rods with a cutting head through the pipe to break a blockage, which suits most simple obstructions. Jetting blasts high-pressure water along the pipe and scours grease and scale off the walls. Jetting costs more but cleans more thoroughly. The company picks the method after seeing the blockage and tells you why in the written quote.
Is it safe to use chemical drain cleaners first?
We would advise against it. Strong chemicals can damage old pipes, are unpleasant to handle and rarely shift a serious blockage. They also make the job harder for whoever arrives, who then has to work around caustic water. Try a plunger, and if that fails, ring us. If you have already used a chemical, tell the company so they take care.
I live in a flat. Who deals with a blocked shared stack?
In mansion blocks like Du Cane Court and in converted Victorian houses, several flats can discharge into one stack, so the blockage may belong to the freeholder or the managing agent. The partner company will say where the problem sits and what you need to report. Clearing the section serving only your flat is a separate, quotable job.
Can a blocked drain cause damp or flooding?
Yes. A drain that backs up can overflow a gully, soak a ground-floor wall or push foul water into a basement. Standing water near a house wall is worth taking seriously, and anything with sewage in it needs proper clearing and cleaning. Ring us as soon as you see water that will not drain, rather than hoping it goes down.
How do I stop it happening again?
Bin fat and wipes instead of pouring or flushing them, fit strainers over plugholes and keep gullies clear of leaves, especially near mature trees. Run hot water down kitchen sinks after washing up. If the same drain blocks twice, a camera survey is the honest next step, because repeat blockages usually point to a damaged pipe.
Do you cover Balham, Furzedown and Wandsworth Common drains?
Yes. We cover Tooting, Tooting Bec, Balham, Furzedown, Upper Tooting and Wandsworth Common. The nearest suitable partner company is sent, and you are texted its name before it arrives. If the blockage turns out to be a wider water problem, our emergency plumbing page explains what to do next, and our Balham page covers the mansion blocks and conversions where shared drains are most common.
