How We Clear Your Blockage in London
Most “plumbers” only use rods. We carry industrial-grade equipment to ensure the blockage is gone for good.
Stage 1: Manual Rodding & Plunging: Internal pipes, toilets, and soft blockages. For simple clogs close to the surface, we use professional steel rods and kinetic rams to dislodge the obstruction manually. This is the quickest and cheapest solution for minor issues.
Stage 2: High-Pressure Water Jetting (HPWJ): External drains, manholes, fat, and grease. Rods often just punch a hole through the dirt. Our van-mounted Jetting units blast water at 3,000+ PSI to scour the pipe walls clean, removing not just the blockage, but the years of grease and scale build-up that caused it. (Included in standard external clearance.)
Stage 3: Electro-Mechanical Machining: Tree roots, concrete, and hard scale. If your drain is choked by tree roots, water won’t cut it. We send a rotating steel cutting head down the pipe to physically grind away roots and concrete deposits, restoring the pipe’s full diameter without digging it up.
What Are the Symptoms of a Blocked Drain?
Not sure if you have a blocked drain in your London property? Check these signs:
The “Gurgle”: If your toilet bubbles when you run the sink tap, you have a trapped air pocket caused by a blockage downstream.
Slow Draining: Water pooling in the shower or sink taking minutes to empty.
Bad Smells: A sulphur or “rotten egg” smell coming from plugholes (often a dry trap or food rotting in the pipe).
Rising Water Levels: If you lift your outside manhole cover and it’s full of water, the main line is blocked.

1. The First Hour (Minimum Charge): Most domestic drain blockages in London are cleared within the first hour using manual rodding or high-pressure jetting.
2. 15-Minute Intervals: If the job takes longer than an hour, we don’t charge you for a full second hour. We charge in clear 15-minute blocks, so you only pay for the exact time we are onsite working.
3. The “Fixed Price” Safety Cap: If our engineer arrives and discovers a major issue (like a collapsed pipe, extensive root ingress, a severe blockage, or the blocked drain is in a shared line) that will take hours to fix, we will stop the clock. We will provide you with a fixed-price quote to complete the rest of the work. You get total control over the cost before we continue.
Your Right to Stop: If we advise that further work is needed (or offer a fixed price) and you choose not to proceed—for example, if you want to claim on insurance or think it is too expensive—that is completely fine. We will stop work immediately. You will only be charged for the time already spent on site.

Why Choose Drain 247 for Drainage Unblocking in London?
We Are Already In Your Borough: We don’t just commute in from the outskirts; our engineers are strategically stationed across North, West, and East London every day. Whether you are in a townhouse in Islington or a commercial unit in Stratford, our local presence allows us to bypass cross-city traffic and guarantee a 60–90 minute response time.
Specialists in London’s Infrastructure: The mix of modern developments and Victorian sewage systems requires a delicate touch. We understand the unique challenges of the capital’s heavy clay soil and aging clay pipework. Unlike general plumbers, our NADC-certified engineers use calibrated High-Pressure Water Jetting to clear blockages safely without damaging fragile older drains.
A Permanent Solution, Not a Quick Fix: We don’t just clear the blockage and leave. We stamp out reoccurring blockages once and for all. If our engineers suspect a deeper structural issue—like tree root intrusion common in London’s leafy suburbs—we carry CCTV equipment on every van. We can investigate immediately and offer “No-Dig” structural patch repairs on the same visit, preventing the blockage from coming back next week.
