Our home city

Drain unblocking in Southampton

Southampton is where we are based and where most of our work takes place. We unblock drains in Victorian terraces in Shirley, Portswood and St Denys, family homes in Bassett, Sholing and Bitterne, shared houses around the university, and flats and businesses in the city centre and Ocean Village.

Older parts of the city still rely on clay drains that are prone to roots and cracked joints, while newer homes more often block because of wipes, fat and food waste. Knowing the difference is how we clear a blockage in a way that stops it coming straight back.

What we do

Drainage services

Drain unblocking is at the centre of what we do, backed up by jetting, CCTV surveys and repairs for drains that need more than a one-off clearance.

Drain Unblocking

Clearing blocked drains, gullies and waste pipes at homes and businesses, then explaining what caused the blockage so it is less likely to come back.

Emergency Drain Unblocking

Urgent help when a blocked drain is overflowing, sewage is backing up or a property can no longer use its toilets and sinks.

Drain Jetting

High-pressure water jetting to clear stubborn blockages and scour away fat, silt, scale and debris from the inside of drain pipes.

Drain Cleaning

Cleaning drains that are slow, smelly or partly blocked, before a small problem turns into a full blockage.

CCTV Drain Surveys

Camera inspections that show the condition of a drain from the inside, so recurring problems and damage can be diagnosed accurately.

Drain Repairs

Repairs for cracked, broken, root-damaged and displaced drains, based on what a camera survey actually shows.

Drain Maintenance

Planned cleaning and inspection for drains that block regularly, busy commercial premises and managed properties.

Commercial Drainage

Drain unblocking, jetting, surveys and maintenance for shops, restaurants, offices, landlords and managed properties.

Driveway & Patio Cleaning

Pressure washing for driveways, patios, paths and steps, removing dirt, moss, algae and weeds from block paving, slabs, concrete and stone.

Blocked fittings and drains

Blocked Drains

Help with blocked outside drains, gullies, inspection chambers and underground drain runs: found, cleared and explained.

Blocked Toilets

Unblocking toilets that will not flush, keep backing up or overflow, and finding out whether the problem is in the toilet or the drain beyond it.

Blocked Sinks

Clearing blocked kitchen and bathroom sinks, including waste pipes and the drains they connect to.

Blocked Showers

Clearing blocked shower trays, wet-room drains and shower waste pipes, where hair and soap build-up are the usual culprits.

Blocked Baths

Clearing slow and blocked bath wastes, overflows and the pipework that connects them to your drains.

Blocked Sewers

Help with blocked main drains, sewer connections and sewage backing up, including working out who is responsible for the blockage.

Signs of a blocked drain

When to call a drain unblocking company

A single slow plughole can often be dealt with at home. These signs usually mean the problem is in the drain itself and needs proper equipment:

  • Water rising in an outside gully or inspection chamber
  • Sinks, baths or showers draining slowly or not at all
  • Toilets filling higher than usual or slow to clear when flushed
  • Gurgling from plugholes or the toilet after water drains elsewhere
  • Unpleasant smells from drains, gullies or manhole covers
  • Water or waste backing up at the lowest point in the property

Not sure? Read our guide on when to call a drain unblocking company, or see what you can safely try yourself.

Common causes we find

  • Wet wipes, sanitary products and kitchen roll flushed down toilets
  • Fat, oil and grease poured down kitchen sinks, which hardens in the pipe
  • Food waste, coffee grounds and rice collecting at bends
  • Hair and soap residue in bathroom waste pipes
  • Leaves, silt and debris washed into outside gullies

How it works

What happens when you call us

  1. Tell us about the problem

    Call or send an enquiry with your postcode and what you are seeing: which fittings are affected, whether water is rising outside and how urgent it is.

  2. Locate the blockage

    We check the affected fittings and lift inspection chambers where accessible to work out where the drain is blocked and which section is affected.

  3. Clear the drain

    The blockage is cleared using the most suitable method for the pipe (rodding, mechanical clearance or water jetting), and the drain is flushed through.

  4. Test and explain

    We run water through the system to confirm it is flowing, then explain what caused the blockage and whether anything else needs looking at.

Frequently asked questions

Where is Clear Drainage based?

Clear Drainage is based in Southampton, Hampshire. We cover the whole city and the surrounding area within roughly 60 miles, including Eastleigh, Winchester, Romsey, Totton, Fareham, Portsmouth, the New Forest and Bournemouth.

What kinds of drain blockages do you deal with?

Blocked outside drains and gullies, toilets, sinks, showers, baths and main drains, at both homes and commercial premises. Where a drain keeps blocking, we can also jet it, survey it with a CCTV camera and carry out repairs.

How much does it cost to unblock a drain in Southampton?

The cost depends on the type and location of the blockage, how easy the drain is to reach, how severe it is and what equipment is needed. Get in touch with details and we will explain the likely cost before any work starts.

Is a blocked drain my responsibility or the water company’s?

In England, you are usually responsible for drains serving only your property within its boundary. Shared drains and public sewers are generally the water company’s responsibility (Southern Water in Southampton). We can help you work out which applies.

Do you work for landlords and businesses?

Yes. We work for homeowners, tenants, landlords, letting and managing agents, and commercial customers including restaurants, shops and offices.
