Why FS Group

Drain engineers for old terraces, mansion blocks and busy kitchens

Blocked drains in Camden usually trace back to the age and use of the building. Georgian and Victorian terraces around Camden Town and Kentish Town run long shared pipes behind the houses. Mansion blocks send many flats into one stack. On Hampstead's hills, old trees push roots into clay joints. In Bloomsbury, colleges and hotels put heavy daily use on old drains.

Drain ownership

Who looks after which drain

Pipe for your home
Inside your boundary, a pipe used by your home alone is yours to maintain. Your part stops where a neighbour's pipe joins it. In a terrace, that can be close to the back wall.
Shared with next door
Past that point, shared drains and sewers fall to Thames Water, in every part of the borough.
Gullies in the street
Camden Council clears the gullies in the road. Yard gullies are for the owner to clear.

The borough climbs from Holborn, on the edge of the West End, up to Hampstead Heath. Drain layouts change from street to street.

Who we work for

Homes, landlords and businesses

Owners and renters

In a Gospel Oak terrace or a Hampstead family house, the camera shows you the fault before anyone digs.

Landlords and agents

Mansion blocks around West Hampstead and Kilburn often share stacks. Managing agents get the footage and a written report for their records.

About CCTV surveys

Kitchens, hotels and colleges

Restaurants on Camden High Street and hotels around Bloomsbury can book drain work outside busy hours. Priority Account holders get quicker attendance on contract rates.

What we see most

The drain problems we fix most often

Wipes in old pipes

Wipes do not break down like paper. They snag at the first bend and catch everything behind them.

Roots on the hills

Old trees around Hampstead and Highgate send fine roots into clay joints. Left alone, they fill the pipe.

Basement flats

Being lowest on the run, a basement flat is where a blockage shows first. Water backs up there before anyone upstairs notices.

Grease from busy kitchens

Oil and fat from kitchens along the High Street cool inside the pipe. Over time, the opening gets smaller.

Leaves in outside gullies

Autumn leaves from street trees around Belsize Park and Primrose Hill fill yard gullies. Rainwater then sits on the surface.

Flats on one stack

Mansion blocks and converted terraces share a soil stack. A blockage high up can back up into every flat beneath it.

Questions from Hampstead to Holborn

Do you cover every part of the borough?
Yes. The list above runs from Highgate and Gospel Oak to Kilburn and Holborn, and we go to all of it. Close to the Brent or Westminster boundary? Ring and the help desk can check your road.
Can old trees block a drain?
Yes. Fine roots get into clay joints, and they are common around Hampstead and Highgate. The machine or jetter cuts them back. A camera then shows whether a liner will keep them out.
Who pays when a terrace shares one drain?
Usually Thames Water, not you. The water companies took on most shared drains in October 2011. Thames Water clears them at no cost to you. A camera shows where your pipe joins the shared section.
Should I survey the drains before buying a flat?
It is worth doing in an older building. We film the drains, then send a written report. Hand it to your solicitor, or bargain with it on price. Book a few days ahead of exchange.
What do blocked drains in Camden cost to clear?
Clearing one starts at £55.00 + VAT a half hour on a weekday, 8am to 6pm. An ordinary toilet or sink rarely needs longer. Jetting, evenings and weekends are priced differently, and you hear that rate before booking.
Do I get the price before you start?
Yes. You get the rate by phone first. If the job grows, the engineer tells you before going further. The bill reflects their time at the rate you agreed.
How soon can someone get here?
That depends on who is free and nearest. You get an honest estimate on the phone. Backed-up sewage is seen to first. Anything else is booked for a time that suits you.
Do you guarantee drain work?
Yes. A six-month workmanship guarantee covers every job, T&Cs apply. Unblocking, repairs and relining all count. Should that fault come back within the six months, phone and an engineer returns to check it.
