Why FS Group

Drain help for terraced rows, tower blocks and estates

Our engineers work from Hackney and Tower Hamlets out to Walthamstow, Ilford and Dagenham. Terraced streets in Leyton and Forest Gate often share a single run. Estates in Barking and Dagenham have long communal drains. Around Stratford, newer blocks are looked after by managing agents, and we work with them directly.

Amazing service from Felix in E17. Identified the problem and came back to advise on the best course of action for the repair when my contractors were working on the garden. Even got stuck in with the work when he didn't have to!

Harry attended our property in Gants Hill for water leak under the cooker area. He investigated the matter very patiently to get to the root cause and resealed the areas where there was gaps and traces of leak. He also talked us through all his plans and closed the job with full satisfaction.

I contacted FS group online and received an immediate response and appointment to look at my blocked toilet. I didn't get the name of the engineer who visited but despite this he was polite and straight away got to work to identify the problem.

Excellent service. I called FS because of a blocked drain on Saturday afternoon. The office explained how much it would cost and James came round a short while later. He was excellent and professional. And ofcourse unblocked my drain.

Found them through Google and I was a bit sceptical about the amount of 5-star reviews. However, they were on time, efficient, proposed the most cost efficient solution and unblocked the drain at a very reasonable cost without trying to get more money out of me. Well done, will use again!

Drain ownership

Who looks after which drain

What you own
Any pipe that drains just your property and stays inside your boundary is yours.
Shared and public
Once a Walthamstow back run serves more than one house, it is a shared drain. Those and the sewers passed to Thames Water in October 2011.
Gullies on the road
Waltham Forest, Redbridge, Newham, Hackney, Tower Hamlets or Barking and Dagenham council clears its own road gullies. Transport for London clears red route ones.
E, IG and RM8 to RM10 postcodes

Most East London streets are Victorian terraces, tower blocks or 1920s and 1930s estates. Each one blocks in its own way.

Who we work for

Homes, landlords and businesses

Families and renters

Whether it is a Becontree Estate home or a Forest Gate terrace, the rate comes before the engineer does.

Block managers

Drains under towers in Poplar and Canary Wharf can be filmed by CCTV. Each survey job finishes with a written report.

About CCTV surveys

Food businesses

Takeaways on High Street North can book drain work evenings, overnight or at weekends. A Priority Account adds faster response and contract pricing.

What we see most

The drain problems we fix most often in East London

Victorian terraces

Streets in Walthamstow, Leyton and Forest Gate often share one drain run. A blockage at one end backs up into gardens along the row.

Blocks of flats

In Tower Hamlets and Newham, a blocked stack in a tall block can flood the lowest flats. We clear the stack and the drain below it.

Interwar semis and estates

Chingford, Gants Hill and the Becontree Estate are mostly 1920s and 1930s homes on their original clay pipes. Roots and shifting joints cause repeat blocks.

Takeaway fat

Takeaways around Stratford and East Ham produce plenty of fat, which builds a hard crust inside the drains.

Roots near the forest

Gardens near Epping Forest in Chingford and Woodford see tree roots work into old clay joints.

Overflowing yard gullies

Back yards in Walthamstow and Leyton fill gullies with leaves and silt, so rainwater backs up to the door.

What people in Walthamstow and Ilford ask us

Do you cover my part of East London?
Yes. We cover every East and North East London borough, from Hackney and Tower Hamlets to Waltham Forest, Redbridge, Newham and Barking and Dagenham.
Our whole terrace has a smell from the drains. What should we do?
Call once and tell us the houses affected. A shared run usually needs one visit, and the water company may cover it.
The road gully outside is overflowing. Is that you?
A gully in the road belongs to the council, or to Transport for London on a red route. Report it to them. If water is coming back up through your own gully, that is a drain we can clear.
How long does a blocked drain take to clear?
A simple blockage is often cleared within the hour. Roots or a broken pipe take longer, and the engineer tells you before going further.
What will unblocking a drain under a Victorian terrace cost?
Standard unblocking is £55.00 + VAT a half hour, Monday to Friday from 8am until 6pm. Out-of-hours work and jetting are priced differently, and you hear the rate first.
Do you add a ULEZ charge for Dagenham?
No. ULEZ is not charged, call-outs are free of charge, and an emergency costs no more.
How soon can someone get to a Stratford block?
When it is an emergency, our aim is to get an engineer to you within two hours.
If you repair my Leytonstone drain, is it guaranteed?
Yes, for six months on workmanship. T&Cs apply.
Can you film the drain under our block in Bow?
Yes. CCTV records inside the pipe, and once the survey is done you get a written report.
