Services
Blocked Drain Clearance
Our 24/7 blocked drain service uses high-pressure jetting and rodding to clear obstructions in domestic and commercial properties. Engineers perform a free 'Quick Look' CCTV survey post-clearance to confirm resolution. Available across Surrey, Berkshire, and surrounding areas with no call-out fees.
Septic Tank Emptying
We operate dedicated waste tankers for septic tank and cesspit emptying, ensuring compliance with environmental regulations. Our fleet covers a 25-mile radius, providing rapid response for both routine maintenance and emergency overflows. Service includes soakaway jetting where required.
CCTV Drain Surveys
Using high-resolution cameras, we diagnose drain conditions for blockages, root ingress, or structural damage. Surveys support house purchases, insurance claims, and planned repairs. Reports include actionable recommendations for remediation.
Drain Lining
Our structural drain lining solutions repair damaged pipes without excavation. A resin-saturated liner is inserted via existing access points, creating a durable, jointless replacement pipe. Ideal for underground drains beneath driveways or buildings.
Private Sewage Systems
We design, install, and maintain private sewage treatment plants and soakaways. Services include regulatory compliance checks, system upgrades, and emergency repairs. Expertise covers Environment Agency requirements for discharge to surface water or ground.

Blockage removed!!
Phoned ASL at just after 0800. Less than 3 hours later, they were here, and half an hour after that, gone again, problem sorted. Great service, friendly technician, charged what they said it would be, and I got a squint up the underground pipe to the road thrown in for free as well.
Brilliant.

We have used ASL several times and always received excellent service and they have all the best equipment. Most recently they got Darren to us the same day. He was very professional and extremely helpful, not just analysing our problem but checking the whole system. Highly recommended!

My understanding of the different kinds of drainage that there are, how they should be plumbed in and what can go wrong if not done correctly has helped me immensely due to Gerry of ASL's willingness to share his knowledge and expertise. ASL are top of my list to call for any drainage issues. Thank you!

Excellent service, did exactly what they said they were going to do. Two really helpful and friendly guys arrived and sorted the problem out with the minimum of fuss - both are a credit to ASL. Very, very happy with the service and solution provided. Thank you.
