Drains in Harrow: what our engineers see
Most of Harrow was built up quickly in the 1920s and 1930s as the Metropolitan line encouraged new suburbs at Rayners Lane, North Harrow, Pinner and Stanmore. The result is street after street of semi-detached and detached houses, often with drains shared along the backs of neighbouring gardens. Those pipes are approaching a century old, and settlement, cracked joints and root intrusion are typical reasons why they start to block.
Older pockets add variety. Harrow on the Hill and Pinner's old village have much older buildings, Wealdstone and Greenhill have Victorian and Edwardian terraces, and post-war estates fill parts of Harrow Weald and South Harrow. Across all of them, rear extensions, garage conversions and loft bathrooms have increased the load on original drains, and work near or over a drain can damage it or bury access points. A CCTV survey before building helps avoid surprises.
Harrow is hilly and leafy, with large gardens, Stanmore Common, Harrow Weald Common and many mature trees close to houses, so roots are a common cause of slow or blocked drains. Harrow town centre, Wealdstone High Street and the parades in Kenton and Rayners Lane host many restaurants and takeaways, and fat or grease from their kitchens can cause blockages unless drains and grease traps are maintained.

Harrow drainage FAQs
Do you come out to Pinner, Stanmore and Hatch End?
Yes. We cover all of Harrow, including Pinner, Hatch End, Stanmore, Canons Park, Belmont, Harrow Weald, Wealdstone, Kenton, Headstone, North Harrow, Rayners Lane, South Harrow and Harrow on the Hill. Call 0800 470 0946 for urgent problems, or choose a morning, afternoon or late-afternoon slot through our online booking page.
Why is my 1930s house in Rayners Lane getting repeated drain blockages?
Houses of that age often have clay drains with cracked or shifted joints, and roots from garden trees can find their way in. Each crack or root mass catches paper and wipes, so blockages return. Jetting clears the pipe, and a CCTV survey shows whether there is damage that needs repair to stop the problem recurring.
Do I need a drain survey before extending my house in Harrow?
It is a good idea. Many Harrow homes have a drain or inspection chamber close to where a rear or side extension would go. A CCTV survey shows the route and condition of the pipe, helping your builder plan around it. If you will build over or near a public sewer, Thames Water may require a build-over agreement.
I rent my home in Wealdstone. Should I call you or my landlord?
Usually your landlord first, as landlords are normally responsible for drains in rented homes. Check your tenancy agreement, because tenants may be asked to pay if the blockage was caused by wipes, fat or other items. If it is an emergency and you cannot reach your landlord, call us on 0800 470 0946.
