Frequently Asked Questions

Answers to the questions we are asked most often about blocked drains, costs, coverage and who is responsible for what.

Booking and coverage

Which areas does Clear Drainage cover?

We are based in Southampton and cover the city and surrounding area within roughly 60 miles, including Eastleigh, Winchester, Romsey, Totton, Hedge End, Fareham, Portsmouth, the New Forest and Bournemouth. See our areas page for the full list, and contact us with your postcode if you are unsure.

Do you work on homes and businesses?

Yes. We work for homeowners, tenants, landlords, letting and managing agents, and commercial premises such as restaurants, shops and offices.

What information should I give when I get in touch?

Your postcode, which fittings are affected (toilets, sinks, showers, outside drains), whether water or sewage is rising anywhere, how long the problem has been going on and how urgent it is.

Can you attend urgently?

We are open 24 hours a day, 7 days a week. Tell us if your problem is urgent. Attendance times depend on your location and existing jobs, and we will always give you an honest answer about when we can get to you.

Costs

How much does drain unblocking cost?

It depends on the type and location of the blockage, how accessible the drain is, how severe the problem is, the equipment needed and how long it takes. Contact us with details and we will explain the likely cost before any work starts.

Will I know the cost before you start?

We will explain the expected cost before starting work. If we find something unexpected, we will talk to you before going any further.

Does home insurance cover drain problems?

Some policies cover accidental damage to underground pipes, and some include drainage cover. Check your policy and speak to your insurer before work begins.

Responsibility for drains

Am I responsible for my drains?

In England, you are usually responsible for the drains that serve only your property and sit within its boundary. Drains shared with neighbours, lateral drains beyond your boundary and public sewers are generally the responsibility of the local water company.

Who looks after public sewers in Southampton?

Southern Water is responsible for public sewers in Southampton and most of South Hampshire. In the Bournemouth, Christchurch and Poole area, it is Wessex Water.

I rent my home. Who should arrange drain unblocking?

Check your tenancy agreement and contact your landlord or letting agent first, as drainage is often their responsibility. If a blockage was caused by misuse, the landlord may seek to recover costs.

Drainage problems

What causes most blocked drains?

Wet wipes, fat and grease, food waste, hair, sanitary products, leaves and silt, and tree roots entering older pipes.

Why does my drain keep blocking?

Recurring blockages usually point to an underlying cause such as build-up, root ingress, a dip in the pipe or a damaged joint. A CCTV drain survey can show what is happening.

Are drain unblocking chemicals safe to use?

They rarely clear a full blockage, can damage some pipework, and leave caustic water that makes the drain hazardous to work on. We would not recommend them for anything more than light maintenance.
