This operative was very thorough in making safe my leaking kitchen sink. He then came back a week later and fixed it permanently. The work was done to a high standard, he replaced taps, all pipework under the sink and sealed the lot. I am very happy with the job done and couldn't ask for any better. He was polite, cleaned up after his work and observed covid distancing. It is so good to see someone take pride in his work like this young Man. My kitchen is now leak free and my sink looks brand new.

Fantasic service provided by William today. I had been struggling to find the blockage for a couple of days without any luck. He located the blockage and cleared it in just over an hour. I am more than happy to recommend F S Drainage to anyone. Thank you once again guys.

Got two drains unblocked on the same day for 2 houses. I was a little skeptical about using them based on pricing per 30 mins but they were professional, fast and got the job done. The team member Felix was friendly and efficient. Booking on the phone was easy. They explain well about their pricing. I’m satisfied.

Called FD Drainage at 11.58, contacted us at 12.10 to say Josh would be with us for 12.30. He arrived before 12.30, unblocked the outside drain, which was blocked with fat. Josh was friendly, efficient, tidy and professional. A credit to himself and FS Drainage. Would recommend them again. Hope you get Josh

Drain ownership

Who looks after which drain

The part you own
The pipe serving only your home, inside the boundary, is yours. That applies on a Purley hillside or in a Thornton Heath terrace.
Shared and public drains
Thames Water took over shared drains and public sewers in October 2011. A run shared behind a Norbury terrace counts as one.
Road gullies
Your road gully is the borough council's to clear. Transport for London handles any on a red route.
CR0 to CR8, SE25 and SW16

Croydon has a town centre of offices, flats and restaurants, and wide suburbs of family homes around it.

Who we work for

Homes, landlords and businesses

Households

Whether you own a Selsdon house or rent in South Norwood, you get the rate before an engineer sets out.

Block owners and agents

Towers in the town centre share drains between many flats. We film the run, then send a written report.

About CCTV surveys

Offices and restaurants

Restaurants in the town centre can book jetting for after 6pm, overnight or weekend slots. Priority Accounts add faster response and contract pricing.

What we see most

The drain problems we fix most often in Croydon

New flats in the centre

Blocks around East Croydon and West Croydon share drains between many flats. One misuse can block the run for everyone.

Family homes and gardens

In Shirley, Selsdon and Sanderstead, older pipes and big trees mean roots in the drains.

Food businesses

Restaurants on the High Street and around Boxpark need grease kept out of the pipes. We jet them on a schedule.

Old terraces in the north

Victorian and Edwardian terraces in Norbury and Thornton Heath often share one drain behind the row.

Roots on leafy plots

Leafy plots in Purley and Kenley let tree roots work into old clay joints.

Blocked yard gullies

Leaves and silt fill outside gullies in South Norwood and Addiscombe, so rainwater backs up.

What people ask us, Norbury to Coulsdon

Do you cover Purley and Coulsdon?
Yes. We cover all of Croydon, from Norbury and Thornton Heath down to Coulsdon and New Addington.
Can you maintain drains for our office or restaurant?
Yes. We set up planned jetting and checks, and a Priority Account gives you a named contact and faster response.
What should I do while I wait for the engineer?
Stop running water into the blocked drain and skip chemical cleaners. If you can, find the inspection cover in your garden or drive.
Do you charge by the job or by the hour?
Domestic work is charged by the half hour, with no call-out fee. Larger jobs, such as repairs, are priced as a project.
Is there a call-out fee to Kenley?
No. Nor is there a ULEZ charge, or a premium for emergencies.
Our drain in Thornton Heath is overflowing. When can you be here?
We aim to get an engineer to an emergency within two hours.
Do you guarantee drain repairs in Shirley?
Yes. Workmanship carries a six-month guarantee, subject to T&Cs.
Can you film the shared drain behind my South Norwood terrace?
Yes. CCTV records the pipe from inside, and we write the findings up in a report.
