Our engineers work across Kent, from Dartford and Gravesend to Maidstone, Tonbridge and Ashford. Rochester, Chatham and Gillingham have long streets of Victorian terraces on old clay pipes. Ashford has grown fast, with large new estates on plastic drains. Further south, village houses sit on long runs under gardens and old trees. A camera survey shows which you have before work begins.

Mitch turned up, listened carefully to what I said, and quickly analysed the problem. He explained his method and set about clearing a blockage from an external pipe, and was all done in 15 minutes. Happy to pay his fee and would recommend his services to friends.

Drain ownership

Who looks after which drain

Pipe for your home
A drain inside your boundary that serves only your house is yours to look after. Once it meets a neighbour's pipe, that changes.
Shared with next door
Shared drains and sewers belong to the water company. That is Southern Water across most of Kent, and Thames Water around Dartford.
Gullies in the street
Kent County Council clears the road gullies. In Rochester, Chatham and Gillingham, Medway Council does it instead.

Kent ranges from Victorian riverside towns to farmland villages, so drain layouts differ from street to street.

Who we work for

Homes, landlords and businesses

Owners and renters

In a Gillingham terrace or a detached house in Sevenoaks, the engineer shows you the fault before any work.

Landlords and agents

Flats in Maidstone and Chatham often share drains and soil stacks. After a survey you get the footage and a written report.

About CCTV surveys

Kitchens in Maidstone and Rochester

Pubs and restaurants in Maidstone, Rochester and Tunbridge Wells can book drain work outside opening hours. Priority Account holders get faster attendance and contract rates.

About Priority Accounts

Drainage services across Kent

One phone call covers all of these, from a root-filled pipe in Sevenoaks to a flooded gully in Gravesend. Describe the problem and the help desk sends the right engineer.

Blocked drains in Kent

Most blockages sit in a toilet, sink or yard gully, and a hand rod shifts them. If the main drain is blocked near the road, the machine goes in. Medway terraces often share one run, so we trace where the blockage actually is.

CCTV drain surveys in Kent

Moving to Tonbridge or Sevenoaks? A homebuyer survey films the drains before exchange, and the report goes to your solicitor. Extending your house? A full survey maps the drain under the new build for a build-over application.

Drain jetting in Kent

The jetter blasts water through the pipe at high pressure, scouring out grease, silt and scale. Takeaways in Chatham and Maidstone build up fat quickly, and long country runs fill with silt. We clear it in one visit or set up regular jetting.

Drain repairs in Kent

Clay pipes in older Kent towns crack at the joints, slip out of line or cave in. Tree roots and heavy traffic cause the same faults. We can reset a single joint or replace a broken section. The camera finds the damage first, so digging stays to a minimum.

Drain relining in Kent

If a damaged drain runs beneath a patio, driveway or extension, relining avoids digging it out. We pull a resin liner into the old pipe and cure it in place, leaving a new pipe inside. It works well on long runs under older houses.

Emergency drain services in Kent

If sewage rises through a manhole or a gully overflows at night, ring us at once. The help desk is staffed around the clock, weekends included, and sends the closest available engineer. They stop the flooding first, then explain the cause and how to avoid a repeat.

What we see most

The drain problems we fix most often

Wipes in the toilet

Wipes labelled flushable stay whole in the pipe. They snag at the first bend and block the toilet.

Clay soil on the move

Clay soils in much of Kent dry out and crack in summer, then swell in winter. Old pipe joints pull apart as the ground moves.

Shared terrace runs

Victorian terraces in Rochester and Gillingham often share one drain, so a single blockage can back up several houses.

Fat from takeaways

Kitchens on Chatham and Maidstone high streets rinse fat down the sink, where it hardens and narrows the pipe.

Leaves in outside gullies

Tree-lined streets in Sevenoaks and Tunbridge Wells fill yard gullies with leaves every autumn, so rainwater backs up.

Flats on one stack

Converted Victorian houses in Rochester and Chatham share soil stacks, so a blockage upstairs affects the flats below.

Questions from Dartford to Ashford

Do you cover the whole of Kent?
We cover the towns listed above, from Dartford, Gravesend and Swanley to the Medway towns, Maidstone and Ashford. Sevenoaks, Tonbridge and Tunbridge Wells are on our rounds too. If your town is missing, phone and the help desk will confirm.
Can you clear tree roots from a drain?
Yes. Around Sevenoaks, Tonbridge and Tunbridge Wells, roots work their way into old clay joints. We cut them back by machine or jetter. A camera check afterwards shows whether relining will keep them out.
Is a shared drain my responsibility?
Usually not. Since October 2011 most shared drains have belonged to the water company, so you pay nothing to have them cleared. In most of Kent that is Southern Water, and around Dartford it is Thames Water. A camera survey shows where your pipe joins the shared run.
Do you do homebuyer drain surveys?
Yes. We film the drains at the property you plan to buy and send a written report afterwards. Your solicitor can use it, or you can use it to negotiate on price. Allow a few days for the report before exchange.
What does a blocked drain cost to clear in Kent?
Weekday unblocking, 8am to 6pm, is from £55.00 + VAT for every half hour. That half hour is enough for most toilets and sinks. Jetting and night or weekend visits have separate rates, and you hear the rate before booking.
Will I know the price before work starts?
Yes. You hear the rate when you call, and the engineer talks you through any extra work before doing it. The bill is the engineer's time at that rate.
How quickly can an engineer reach me?
It depends where the nearest free engineer is, and the help desk gives you a straight answer on the phone. Sewage backing up takes priority. Jobs that can wait are booked for a time that suits you.
Is your drain work in Kent guaranteed?
Yes. We guarantee our workmanship for six months, T&Cs apply. That covers unblocking, repairs and relining. If the same problem comes back within that time, call us and we return to check it.
