Unblocking

Drain Unblocking In London

If you have a blocked drain, sink or toilet, we can clear it quickly and professionally. Our experienced drainage engineers regularly deal with blockages in drains, waste pipes, waste disposal units, sani units and macerators.

Our emergency drain service operates throughout London, 24 hours a day. No call-out charges – you only pay for the work carried out.

Jetting

High-Pressure Drain Jetting

When a blockage is difficult to remove, drain jetting is often the most effective solution. Using our high-pressure jetting equipment, we clear blockages in main drains, pipework and toilets for both domestic and commercial customers.

Emergency jetting services are also available when immediate action is required. Our engineers carry their own jetting machines for rapid response.

Inspection

CCTV Drain Surveys

A CCTV drain survey can help identify collapsed drains, cracked pipes, root intrusion, partial blockages and defective pipe lining. These surveys are particularly useful when purchasing a property, helping to avoid costly drainage issues after completion.

Our CCTV inspection equipment identifies drainage faults with precision. Survey footage can be supplied digitally for your records or insurance claims.

FAQs

Frequently Asked Questions

What are the most common reasons for a blocked toilet?

Wet wipes, sanitary products and nappies are among the most common causes. Even ‘flushable’ wipes can cause blockages over time.

How do I unblock a drain in a sink, bath or shower?

Drain cleaning products and plungers may help with minor blockages, but persistent blockages often require professional attention to avoid damaging pipes.

What can a professional drainage engineer do?

Engineers use specialist equipment such as drain jetters, drain snakes, wet vacuums and rods to locate and remove blockages safely and effectively.

Why would I need a CCTV drain survey?

To identify drainage issues before purchasing a property or to diagnose hidden problems such as cracks, collapses or root intrusion within an existing drainage system.

What does it cost to inspect a blocked drain?

There are no call-out charges. Costs depend on the complexity of the blockage and the work required. We provide transparent pricing before any work begins.
