Drainage Specialists Serving Cranleigh and Surrounding Areas

ASL covers Cranleigh and the surrounding countryside, including Alfold, Ewhurst, Dunsfold and Rudgwick. Cranleigh’s village centre is fairly compact, but the catchment around it is properly rural, with a good number of farms and outlying properties running on private drainage rather than mains sewerage. Every job is carried out by ASL’s own directly employed engineers, using ASL’s own equipment.

What We Can Clear for You in Cranleigh

Toilets, sinks, kitchen waste, outside drains, gullies and inspection chambers across the village centre. Out towards the surrounding farmland, septic tanks, treatment plants and cesspits make up a regular part of the work, alongside the standard domestic drainage found on any residential street. Soakaways, main drain connections and CCTV drain surveys round things out, whether the job's in the village or several miles out into the countryside.

Toilets

Backing up because of an outside drain blockage, not internal plumbing.

Ground-floor sinks

Draining slowly or overflowing due to blocked external pipes.

Manholes & chambers

Inspection chambers in the garden or driveway that have surcharged.

Downpipes & gullies

Rainwater downpipes and gully outlets that won't clear.

Soakaways

Systems that aren't draining water away as they should.

Commercial drainage

Foul and surface water systems for businesses of any size.

Why Do Drains Get Blocked?

Cranleigh sits on Weald Clay, heavy ground that holds water and puts real strain on drainage during wet spells, particularly on the flatter farmland surrounding the village. In the older parts of the centre, root ingress from mature trees and displaced joints in ageing pipework are common enough. Fat and grease build-up in kitchens and wet wipes flushed away remain frequent causes wherever you are. Out on the rural properties, private systems bring their own issues, from silt build-up, insufficient capacity for the number of people using them, or simply age, and these need a different diagnostic approach entirely.

Kitchen habits

Fat, grease and food waste hardening inside the pipe.

Bathroom items

Wet wipes and sanitary products — even 'flushable' ones.

Nature

Tree roots, silt and leaves finding their way in.

Wear & tear

Scale build-up, cracks or old pipe materials failing.

Build issues

Renovation debris or pipes laid at the wrong gradient.

How We Fix It, Our 5-Step Process

  1. Call and rapid response Tell ASL what's happening, and an engineer is dispatched to your Cranleigh address, village or countryside alike.
  2. On-site diagnosis Village properties get a straightforward assessment. Meanwhile, rural properties on private systems may need the septic tank or treatment plant checked as well.
  3. Clearing the blockage Jetting, rodding or mechanical drain milling clears the immediate problem, with a CCTV survey used to confirm the cause where needed.
  4. Confirming the fix The customer is shown the evidence that the drain, or the private system, is working properly again. Where it makes sense to do so, the engineer will also spend ten minutes putting a camera down for a complimentary look-see. There's no charge for it, it's simply part of clearing the drain, and it's there to confirm the pipe is running clear and to spot any obvious fault. Note that this is a quick look rather than a full CCTV drainage survey, which is a booked job with different equipment and a written report.
  5. Reporting and next steps Where tank desludging, no-dig lining or a patch repair is needed, ASL explains this clearly and provides a free estimate.

Case in Point: Knowle Lane, near Cranleigh

Recent Drainage Work in Cranleigh

Gerry was called to a property in Knowle Lane, near Cranleigh, with barely any flow through the drains. Clearing the congealed fat was only half the story, the septic tank needed attention too, so we brought in a tanker and used CCTV to establish what was really going on. The customer got a full report with options, including replacing the tank with a modern treatment plant. Read the full job on our Cranleigh case study page.

Having found ASL Limited on multiple recommendation sites I can see why - they have been a pleasure to deal with from start to finish! To assist with investigative works we had Mark and Alex out initially and then Ryan and Max out for further work - both teams were an absolute pleasure to have at our house: polite, punctual and most importantly they were experts in their field. ASL rightly have an excellent reputation as I would not go anywhere else if I need any future help!

We had a blocked drain. Darren attended and confirmed that the blockage was beyond our boundary therefore not our responsibility. Thames water attended and refused to accept it was their issue. Darren returned and promptly cleared the drain for us. He was polite efficient skilled and hard working. We strongly recommend ASL for drainage work.

What a great service! Booked in when I needed it, turned up exactly on time, investigated and sorted the problem and I now have free flowing drains! Then, to cap it all, they wouldn't take my money and said 'we'll invoice you later'. Now that's how to inspire trust! Would I use ASL again? I'm hoping I won't need to but I'll be recommending them everywhere I can!

An outstanding company. Professional, responsive, honest and knowledgeable. A private treatment plant that continually malfunctioned (electrics installed inside the tank. What genius thought that was a good idea?!) has been completely upgraded by ASL. Trenches dug, bespoke risers made on site, new electrics installed, the lot - all done with care and expertise. I cannot recommend them enough. Every single one of their staff are a credit to them.

FAQs

Can you reach a rural property near Cranleigh the same day?

Yes, whether that's in the village itself or several miles out towards the surrounding farmland.

How much does it cost, given some properties are on private systems?

It depends heavily on whether you're on mains drainage or a septic tank, and what's needed to fix it. We always offer a free quote before any work. Calling us and using the enquiry form are both free as well.

Who's responsible for the drain, me or Southern Water?

Southern Water is generally responsible for the public sewer around Cranleigh, but properties on private systems are the homeowner's responsibility entirely, tank and all.

Do you service septic tanks for farms around Cranleigh?

Regularly. Septic tanks, treatment plants and cesspits for rural properties not on mains sewerage are a core part of the work here.

What is a CCTV drain survey used for?

Identifying exactly what's wrong inside a pipe, whether that's a mains-connected drain or part of a private system. That's the full survey, booked in with the right camera equipment and reported on afterwards. It's not the same as the complimentary 10-minute look-see included when we clear a blockage, which is a quick check to confirm the pipe is clear.

Will fixing a private system mean major garden work?

Not always. Some issues can be resolved with jetting or a straightforward repair, without extensive digging.
