Blocked Drain Clearance Harlesden | NW10 Drainage Experts
Is a backed-up toilet or a slow-draining sink causing disruption at your property near Harlesden High Street or Roundwood Park?
Harlesden presents a unique set of drainage challenges defined by its high concentration of converted Victorian properties. Many townhouses in Craven Park and Manor Park Road have been converted into multiple flats (HMOs). This means a drainage system originally built for one family is now handling the waste of five or six households, leading to frequent “system overload” and blockages. Additionally, the proximity to the Park Royal industrial zone means the main sewers often handle heavier commercial waste than standard residential areas.
We have been serving the residents in Willesden Junction, Craven Park, Stonebridge and Harlesden community for over 35 years. We understand that navigating the A404 and busy High Street traffic requires local knowledge. We target a 90-minute response time, ensuring we reach you quickly to prevent sewage backup.

Harlesden Expert Drainage Solutions
HMO & Multi-Occupancy Clearance: We specialize in clearing the “overloaded” stacks found in Harlesden’s converted flats. We use electromechanical cables to clear internal blockages where high-pressure water cannot be used due to access restrictions.
Commercial Grease Management: With Harlesden High Street’s density of takeaways and restaurants, fatbergs are a major issue. We provide rapid high-pressure jetting to pulverize hardened grease deposits before they cause a total sewer collapse.
Hard Water Scale Removal: NW10 is a hard water area. Over time, limescale builds up inside cast-iron pipes, narrowing the flow. Our 4000psi jetting units are specifically calibrated to cut through this calcification restoring the full bore of your pipes.

Specific Drainage Challenges in Harlesden
System Overload in Converted Flats: The Victorian sewers in NW10 were not designed for modern washing machines and dishwashers running simultaneously in one building. We install anti-flood valves to prevent back-flow during peak usage times.
Industrial Silt Accumulation: Properties near the Grand Union Canal and industrial estates often suffer from silt and grit entering the surface water drains. We use high-flow suction units to remove this heavy debris.
Rodent Control in Shared Sewers: The aging brickwork of Harlesden’s sewers is a common entry point for rats. We install stainless steel rat blockers within the pipe to stop pests entering your home through the toilet.

Deepak & Puja Prabhakar
I live above flats and called my landlord who sent out their plumber and a day later it was still blocked. So I gave a try this company who looked reputable. After an hour they managed to unblock the sinks and toilets in my flat and until now it is still in working order.
