Why FS Group

Drain engineers for terraces, converted houses and flats over shops

Our drainage services in Haringey run from Bounds Green and Muswell Hill across to Tottenham Hale. Blocked drains here often come down to who shares what. Tottenham has rows of Victorian and Edwardian terraces, often on one shared drain. Crouch End has houses split into flats, and Wood Green High Road has flats above shops. Muswell Hill has Edwardian houses on hilly streets, with mature trees near the pipes.

Drain ownership

Who looks after which drain

Pipe for your home
Your own pipe stops where it meets a neighbour's, which in a terrace can be close to the house. Up to there, it is yours.
Shared with next door
Past that point, shared drains and public sewers are Thames Water's to look after.
Gullies in the street
Haringey Council clears the gullies in the road. Your own yard gully is for the owner to keep clear.

Streets drop from the hills of Highgate and Muswell Hill down to the Lea Valley. Where your pipes run varies from road to road.

Who we work for

Homes, landlords and businesses

Owners and renters

In a Tottenham terrace or a Muswell Hill family house, we find the fault before anyone lifts a slab.

Landlords and agents

Converted houses in Crouch End and Hornsey often have several flats on one stack. Freeholders and managing agents get the survey film and a written report.

About CCTV surveys

Food shops in Harringay and Wood Green

Restaurants and food shops on Green Lanes and Wood Green High Road can have drains cleared after closing time. On a Priority Account, shops get faster attendance and contract rates.

What we see most

The drain problems we fix most often

Wipes in a shared run

Flushable wipes do not break down. On a terrace, a neighbour's wipes can stop your drain too.

Roots on hilly streets

Mature trees around Muswell Hill and Alexandra Park send fine roots into old clay joints. Slowly they choke the pipe.

Flats above shops

On Wood Green High Road, a flat's soil stack can meet the shop's drain below. What the shop sends down affects you.

Fat from food shops

Busy kitchens on Green Lanes can send fat down the sink. It cools in the pipe and narrows it for everyone downstream.

Leaves in outside gullies

Street trees in Crouch End and Highgate drop leaves into yard gullies each autumn. The next heavy rain then backs up.

Flats on one stack

Converted houses in Crouch End and Stroud Green often share one soil stack. The ground-floor flat tends to flood first.

Questions from Highgate to Tottenham Hale

Do you cover my part of the borough?
Yes. Our engineers work in every place listed, from Highgate and Fortis Green to Seven Sisters and Tottenham Hale. Near the Enfield or Islington border? Phone and the help desk will check.
I live above a shop. Can you clear the drain?
Yes. A rod or jet reaches the stack and the drain below it. We can work before the shop opens or once it shuts, so trade carries on.
Our whole terrace is on one drain. Who pays?
Usually Thames Water, if the fault is on the shared part. Most shared drains passed to water companies in October 2011. A camera run shows where your own pipe joins, so you know which side the fault is on.
I am buying a terrace. Can you film its drains?
Yes. We film the drains of the house or flat you are buying and send a written report. It helps your solicitor, and it gives you grounds to haggle on price. Try to book some days ahead of exchange.
What do blocked drains in Haringey cost to clear?
Between 8am and 6pm on a weekday, clearing a blockage costs from £55.00 + VAT per half hour. Many toilets and sinks need no more than one half hour. Jetting, nights and weekends are priced separately, and you hear that rate before booking.
Do I know the price before you start?
Yes. You get the rate over the phone. If the job turns out bigger, you hear why before more work starts. Time on site is charged at that rate.
How soon can someone get to me?
Much depends on where our nearest free engineer is. Ring and you get an honest estimate from the help desk. Sewage backing up goes first, and you pick a time for anything else.
Are your drain repairs guaranteed?
Yes. We back every drain job with a six-month workmanship guarantee, T&Cs apply. It covers unblocking, repairs and relining alike. Ring us if the fault is back within those months, and we return to look.
