Why FS Group

Check the drains before the builders arrive

A CCTV drain survey in Harrow is often booked before an extension or a loft room. Much of the borough was built in the 1920s and 1930s. Many of those homes still drain through their original clay pipes. A camera run shows the state of each pipe and the route it takes.

Really happy with the service so far that Mitch provided. He turned up at short notice to do a cctv survey, was polite and courteous and knew what he was doing. Advised me on what he was going to look at and gave me a summary of his findings and recommendations, and should get the report back within the week. Would definitely recommend!

Uchenna came and unblocked our drain which had been blocked for at least 7 months. He did it very quickly and explained our options before starting. He was very professional and would definitely recommend. I booked this appointment on Friday and was able to get an appointment for Saturday. Very happy.

Drain ownership

Who looks after which drain

Pipe for your home
Your survey shows the point where your own drain meets a shared one. Up to there, repairs fall to you.
Shared with next door
From that point on, Thames Water is responsible for shared drains and the sewer. The change came in October 2011.
Gullies in the street
Gullies on the road are cleared by the council. On a red route, Transport for London deals with them.

Many local semis have been extended over the old drain. The film shows what sits under the new floor.

About CCTV surveys

What we see most

Common faults on Harrow surveys

Ageing interwar clay

Clay pipes laid in the 1920s and 1930s crack and part at the joints. Waste then catches on each rough edge.

Drains under extensions

Kenton semis extended at the back and into the loft often join new bathrooms to the old pipe. The camera shows its condition.

Roots from tree-lined roads

Street and garden trees in Pinner find small gaps in old pipes. The roots then spread inside and trap paper.

Rainwater and waste pipes

Some South Harrow homes have separate pipes for rainwater and waste. The survey confirms which pipe is which before work starts.

Long garden runs

Stanmore houses with large gardens can have long drains to the road. A fault far down the run shows clearly on camera.

Scale and grease

Hard water builds scale inside the pipe, and kitchen grease sticks to it. Between them the pipe slowly narrows.

Questions before you book a survey

How long is the engineer on site?
Usually an hour or so for a house. Long runs and bigger buildings take more time. You see the film before the engineer goes.
Do you survey a drain that is blocked?
We clear it first, as the camera cannot pass a blockage. Clearing or jetting is charged at our unblocking rates.
Whose job is a fault on a shared drain?
It is Thames Water's if the fault is on the shared section or the sewer. The report shows exactly where it is.
How quickly is the report sent?
Most reports follow within a few days. If you are buying, leave time before exchange.
What is the price of a CCTV drain survey in Harrow?
Look and See checks start at £130.00 + VAT. A comprehensive survey or a drain map starts at £250.00 + VAT. We confirm the cost before you book.
Will the report suit a build-over application?
Yes. We film to Thames Water's standard and write the report to be forwarded. Tell us at booking if a set format is needed.
Is a survey needed before relining?
Yes. It measures the pipe and pins down each crack, so the liner fits the run. We film the pipe again afterwards.
Is work after a survey guaranteed?
Yes. We guarantee repairs and relining for six months, T&Cs apply. Should the fault return in that time, we come back to check.
