Blocked Drains and Drainage Services in Dover

Drainage on the Hills and Valley of Dover

Dover is squeezed between the White Cliffs, with the castle looking down from the eastern heights and the ferry port spread along the seafront below. The River Dour runs through the middle of the town in a narrow valley, and streets climb steeply away from it on both sides, many lined with terraces stepped one above the next.

That shape affects how drains behave. Water from homes higher up the slope runs a long way downhill before it meets the sewer, so a fault in one garden can show up as a problem in another further down. Steep gardens, steps and narrow paths also mean that getting equipment to a manhole takes some thought. We are set up for it, with gear that can be carried and hoses long enough to reach from the road.

CCTV Drain Surveys in Dover

On a hillside, digging to look for a fault is hard work and often unnecessary. A CCTV drain survey shows what is wrong without breaking ground. We send a small camera along the pipe from a manhole or gully and record what it sees: cracks, roots, joints that have moved, or sections where the pipe has sunk and water lies in a pool.

The footage pins down exactly how many metres along the run the problem lies, which matters on a sloping site where every metre of digging counts. We hand over the video with a short report written for homeowners, not engineers. Anyone buying an older terrace in Dover may find a survey money well spent before contracts are exchanged. Find out more about our CCTV drain surveys.

What a survey can show on a sloping run

Pipes on a slope tend to suffer at the joints, where the ground has crept downhill a little over the years. The camera picks up joints that have opened or stepped, and spots where roots have found their way in.

Drain Repairs in Dover

Once a survey has found the fault, the repair can be planned around it. Cracked or leaking pipes that are still in shape can often be relined from the inside, which avoids digging up steps, terraces or retaining walls. We insert a felt tube wetted with resin, push it hard against the inside of the old pipe with air pressure and let it set into a hard, smooth bore.

Where a pipe has broken or collapsed, that length is excavated and a new one laid. Either way you see the footage first and know the cost before we begin, with no hidden charges added later.

Drain Unblocking in Dover

For a straightforward blockage, drain unblocking is usually quick. Starting at the lowest cover that is full, we rod or machine the line upwards until the water drops, then flush every branch that feeds it. Before leaving we explain what caused the stoppage so it is less likely to happen again.

Blocked Drains in Dover

The usual causes of blocked drains in Dover are the same as anywhere: cooking fat, wet wipes, nappies, leaves and silt. What is different is where the blockage tends to end up. On a hill, solids are carried down quickly and then gather at the first bend, joint or change in level, which is often a shared manhole at the bottom of a row of houses.

Clearing it properly means working from the lowest blocked point and making sure every pipe that feeds it is running again. Our blocked drains page explains how we deal with them.

Blocked Toilets in Dover

A pan that refuses to clear usually means a blockage in the toilet bend, further down the stack, or in the drain below the garden. We test each in turn and clear whichever has stopped. The blocked toilet page lists common causes.

Unblocking Baths in Dover

Slow baths in Dover homes mostly come down to hair knotted with soap scum. Taking off the trap and cleaning the pipe beneath it is normally enough, and we test the overflow while we are there. Read the blocked bath page for tips.

Commercial Drainage in Dover

The port brings a steady flow of travellers through the town, and with it hotels, cafes, takeaways and businesses along the seafront and in the town centre. Kitchen drains in busy food premises take a heavy load of fat and food waste, and long runs on commercial sites often have several gullies and sinks feeding into one line.

We look after commercial drainage in Dover with unblocking, high pressure jetting, camera surveys and repairs, and we can arrange planned cleaning so kitchen drains are cleared before they cause a closure. See our commercial drainage page.

Drain Jetting in Dover

Jetting uses high pressure water to scour the inside of a pipe, lifting out grease, scale and silt that rods leave behind. It is the right tool for long runs that keep slowing up, and for kitchen drains coated in fat. Read more on our high pressure jetting page.

Emergency Drainage in Dover

Sewage coming up through a floor drain or a manhole overflowing down a garden path needs dealing with straight away. Emergency calls are taken 24/7 from across Dover, including River, Whitfield and Buckland in CT16 and CT17, with the aim of arriving within the hour. Our emergency call outs page explains how it works, and Folkestone, along the coast, is covered too.

Questions We Hear in Dover

What people living on the slopes and in the valley of Dover tend to ask us.

Yes. Our rods and drain machines are made to be lifted and carried, and a jetting hose reaches a long way from the van. If you let us know about steps or a narrow path when you call, we can plan the visit and bring the right kit.

It can be. A blocked or broken drain uphill can let water escape and follow the slope down, and blocked gullies can overflow onto lower ground after heavy rain. A camera survey and a check of nearby gullies usually show where the water is coming from.

Older terraces in Dover often share one pipe that runs behind or beneath the houses before it reaches the sewer. As a rule, the stretch serving only your home inside your boundary is yours, while a pipe shared with neighbours beyond it usually belongs to the water company. A survey shows where one ends and the other begins.

Not always. A hairline crack with no roots or leaks may simply need watching, while an open crack letting in roots or losing water should be dealt with sooner. You get to watch the recording with us, hear what we would recommend, and make the call yourself.

We do. Kitchen drains in cafes, hotels and takeaways build up fat steadily. We clear blockages and can jet the pipes on a regular basis to keep them flowing.
