Toilets, sinks, kitchen waste, outside drains, gullies and inspection chambers across Leatherhead's residential streets. Properties nearer the Mole sometimes deal with surface water and groundwater issues that streets further from the river don't see, while the town's older Victorian housing carries the aged clay pipework typical of its era. Soakaways, main drain connections and CCTV drain surveys make up the rest of the regular workload, alongside drainage for the shops and offices around the town centre.
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?
Leatherhead sits on a mix of gault clay and chalk close to the North Downs, and its position in the Mole Valley means some streets are genuinely prone to flooding after heavy or sustained rain, which puts real pressure on older drainage. In the town’s Victorian streets, root ingress from mature trees and displaced joints in ageing pipework are common issues. Fat and grease build-up in kitchens and wet wipes flushed away remain frequent domestic causes everywhere. Closer to the river, silt washed in during high water can also work its way into drainage that already sits close to the water table.
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
- Call and rapid response Describe the problem, and an engineer is dispatched to your Leatherhead address, usually the same day.
- On-site diagnosis A CCTV drain survey is used wherever the cause isn't obvious, which comes up often on properties nearer the river.
- Clearing the blockage High-pressure jetting, rodding or mechanical drain milling, chosen to suit the pipe and problem found.
- Confirming the fix The engineer confirms the drain is flowing freely and shows the evidence. Where it's appropriate, a complimentary 10-minute CCTV look-see follows at no charge, just a quick look down the pipe to check it's running clear and to pick up anything obviously wrong. That look-see is part of the blocked drain service, not a full CCTV drainage survey.
- Reporting and next steps Where no-dig lining or a patch repair is needed, ASL explains the findings and provides a free estimate.
Case in Point: Private Drainage System Filling Too Quickly
Recent Drainage Work in Leatherhead
A customer called because their private drainage system was filling far too quickly. Carrying our own diggers and equipment, we exposed the drainage and found a broken inspection chamber cover letting surface water pour in whenever it rained, plus root intrusion further upstream. We photographed everything and set out the permanent repair, arranging reduced-price scheduled emptying to keep things working in the meantime. Read the full job on our Leatherhead case study page.

FAQs
How quickly can someone get to me in Leatherhead?
Same-day response is the aim, with most blockages cleared within 30 minutes once the engineer's on site.
What will it cost to unblock?
Depends on the blockage and equipment needed. A free quote is always given before any repair work starts. Calling us and sending an enquiry are both free.
Is the drain my job or Thames Water's?
Thames Water is generally responsible for the public sewer in Leatherhead. But pipework within your boundary is yours to maintain.
Does the River Mole cause extra drainage problems?
It can. Properties nearer the river sometimes see groundwater rise close to the surface after heavy rain, adding pressure to local drainage.
What's the purpose of a CCTV drain survey?
It shows exactly where a blockage sits and what's causing it, particularly useful when river-adjacent pipework makes the cause harder to judge. That's a booked survey with its own camera equipment and a written report. It's a different thing from the complimentary 10-minute look-see included when we clear a blockage, which is a quick check rather than a full inspection.
Do repairs always mean digging up the garden?
No. No-dig lining or patch repair often solves the problem instead, depending on the survey.
