Business overview

At ASL Limited, we are passionate about drains and specialise in all aspects of drainage and watermains. All our calls are handled by friendly and helpful human beings.

Fast, reliable & efficient blocked drain service at a fixed price of £69 +VAT. Most blocked drains we attend are cleared within half an hour. Being a medium sized company, we have all the equipment we need on board our drain clearance vehicles without having to charge through the roof.

Usually, if your blockage is not cleared within an hour, that indicates there may be something else causing the blockage & it's not a simple blocked drain. That in turn would need further investigation but we would quote for any additional work so you as the customer can choose whether to continue or not.

When we say drainage specialists - we mean all kinds of drainage. We are leaders in the installation of septic tanks, treatment plants & pumping stations – priding ourselves on giving our clients a quick solution to any drainage issues you are experiencing.

Drainage is never a problem until it stops working, or when purchasing a house with a private system. Whether you have a blocked drain or sewer, require a CCTV drain survey or a new treatment plant installation, we are fully trained & have over 30 years experience in the industry.

Based in Guildford we cover multiple counties around London. We have a postcode checker on our website so you can see if we cover your area.

We are happy to help & provide you all the impartial advice you might need. No job is too big or too small - simply give us a call & chat to one of our friendly office team.

*Blocked drains clearance includes rodding to restore flow. If there are obstructions in the pipework preventing clearance, or alternate methods of clearance are required, we will re-quote for further works.

If you have discovered that your drain is contaminated with fats, silt or a build-up of scale, we would strongly advise that the drain is jetted as a blockage is inevitable. Regular visits to your premises on a planned basis can avoid costly downtime due to blockages caused by fat build up etc.
Once a defect has been identified in the pipework, we can provide you with a solution to rectify the problem. Our most popular method of repair is by installing a resin based structural liner into the pipework, a method which has been successfully used over the last 15 years and prevents digging.
ASL CCTV drain surveys are undertaken to give a speedy evaluation of any suspected damaged pipework. A CCTV camera inspects the drainage system from the best position - inside the pipe. It is therefore ideal for finding any structural damage or defects.
We use many different methods to clear blockages and we will always find a solution, no matter how big or small the problem is. Once we have rectified the immediate problem, we will check the drain to determine the cause of the blockage and provide you with a solution to prevent re-blocking.
ASL Ltd specialise in watermain installations. We have our own moling equipment which allows us to install a new watermain or divert an existing run without the need for an extensive excavation.
ASL Ltd engineers have the knowledge and experience to give you the best possible service and product for your requirements. We also stock pumps from many leading manufacturers. Whether you require an annual / bi-annual pump service, we can cater for your requirements and advise on the best service.

Excellent company quick and true to their word

I called ASL out to resolve a blocked outside drain. They came out on the day and gave me a call to let me know they were 30 minutes away. The blockage could not be resolved by normal means, so they dispatched a truck and a cctv. They cleaned up the overflow, found the problem. Came back 2 days later, as agreed and on time. Completed the work. The guys were very efficient and friendly, well dressed. Great company will advise all in the village to use ASL, any issues we have with the drainage they will be our first call.
