Blocked drains cleared fast

Most blocked drains are straightforward once the right access point is found. One experienced ASL Limited drainage engineer attends and normally clears the blockage in under 30 minutes.

In the majority of cases, the blockage is cleared for £99 including VAT.

If roots, collapsed pipework, or a sunken joint is found, the camera footage is shown and everything is explained clearly before any further work is agreed. The goal is to stop the problem returning, not just get things flowing for now.

If you want help with a blockage, read about blocked drain clearance.

CCTV camera surveys

A CCTV camera survey shows the true condition of your drains. The footage is explained in simple, clear language so you can understand what is happening and what needs to be done.

Case study: Woking

A customer had foul smells at the side of their property. An old clay gully was found with a loose outlet pipe. The gully was replaced and the outlet was refitted correctly. The smells were gone instantly.

Case study: Knaphill

A septic tank was discharging slowly. Testing showed rainwater entering through a cracked chamber lid. The lid was sealed properly, the tank was serviced, and full flow was restored.

Drain repairs

Some drains keep blocking because the pipe is damaged, joints have dropped, or the fall is no longer right. Clearing the blockage helps short term, but repairs stop repeat problems.

Repairs can include patch lining, structural relining, excavation repairs, chamber renewal, and fall corrections.

If you want to explore repair options, read about drain repairs.

Septic tanks and treatment plants

Private systems can be quiet for years, then suddenly become stressful. Smells, slow drainage, soggy ground, or alarms often mean the system is overloaded or needs maintenance.

Support includes installation, replacements, upgrades, servicing, and land drain or soakaway assessments.

If you have a private system in Woking, West Byfleet, Pyrford, Horsell or Knaphill, read about private sewage systems.

Main drain connections

Some properties can connect to the public sewer, but the process can feel complicated. Distance, gradient, permissions, and roadworks all matter.

ASL Limited can handle permissions, excavation, and final connection to the public sewer.

If you are considering this option, read about main sewer connections.

Pumping stations

When waste or surface water cannot reach the discharge point by gravity, a pumping station may be needed. A well designed system should be reliable and should include an alarm for protection and peace of mind.

If you need help with a pumping station, read about pumping stations.

Gully cleaning

Gullies and channels can quietly fill with silt, leaves, and grit. Flooding often follows when heavy rain hits and the water has nowhere to go.

Deep suction and jetting can keep private roads, drives, and estates flowing properly.

If you want preventative maintenance, read about gully cleaning.

How quickly can a blocked drain be cleared?

Many blockages can be cleared in under 30 minutes once the right access point is found. Some jobs take longer if the blockage is deep, repeated, or linked to damage in the pipe.

What does the £99 including VAT cover?

The £99 including VAT price applies in the majority of straightforward blocked drain cases. If roots, collapse, or other damage is found, the issue is explained and options are provided before any further work is agreed.

Why do foul smells appear at the side of a property?

Smells can escape when a gully is cracked, a chamber cover is not sealed, or an outlet pipe is loose. Fixing the damaged section can stop smells quickly.

Can rainwater cause septic tanks to discharge slowly?

Yes. Rainwater entering through a cracked lid or poor seal can overload a private system and slow the discharge. Testing can confirm where water is getting in so it can be stopped.

When is a CCTV drain survey worth doing?

A CCTV survey is useful when blockages return, smells keep coming back, or there is flooding with no clear cause. It shows the condition of the pipe and helps target repairs.
