Blocked Drains in Finchley

Blocked drains in Finchley are something we deal with every week, from East Finchley and Church End to North Finchley and Tally Ho Corner. Greater London Drainage covers the whole of N2, N3 and N12, with engineers based in North London and a typical arrival time of 60-90 minutes, day or night.

What we find under Finchley streets

Most of Finchley was built between the 1890s and the 1930s: Edwardian terraces off Ballards Lane and Regents Park Road, interwar semis towards Woodside Park, and mansion blocks along the High Road. Many of these houses still run on their original salt-glazed clay pipes. Finchley sits on heavy London Clay, which shrinks in dry summers and swells in wet winters, and that movement opens the joints in old clay runs. Mature street trees on roads around Victoria Park and the Dollis Brook valley then send roots into those joints, and roots are behind a large share of the external drain blockages we clear in N3 and N12.

Inside the home the picture is different. Converted flats in East Finchley often share one soil stack between two or three households, so a blockage in a ground-floor branch can back up into the flat below. Along the High Road and around Finchley Central we also attend restaurants and takeaways where fat and food waste build up in the gully outside the kitchen.

How a Finchley call-out works

• We locate the blockage, using a CCTV camera where the cause is not visible from the chamber
• High-pressure water jetting clears grease, silt and paper; a root cutter deals with root intrusion
• A camera check after clearing shows the pipe is running freely
• You get the CCTV footage and a written note of the pipe condition

Every job is priced before we start, with no call-out fee. If the camera shows a cracked or displaced section, we explain what we found and quote for the repair separately, so you decide what happens next.
