Why Commercial Sites Need Specialist Help
Commercial drains work much harder than household ones. They handle higher volumes of water, more foot traffic, and often cover large areas like car parks and loading bays.
Businesses rely on ASL because:
- Time is money: Downtime costs you revenue.
- Health & Safety is vital: You need to protect staff, customers, and tenants.
- Compliance matters: Insurance companies and local councils require systems to be maintained correctly.
- Prevention is better than cure: A planned schedule is cheaper than an emergency repair.

Our Commercial Services
We cover everything from a single blocked toilet to major site excavations. Because we don’t outsource, we handle the whole process from start to finish.
1. Reactive Support (Unblocking & Repairs) – When things go wrong, we move fast. We prioritise commercial callouts to get your site operational again.
- High-pressure water jetting to clear blockages.
- Emergency tanker services for flood relief.
- Rapid repairs to burst water mains or collapsed pipes.
2. Planned Maintenance (PPM) – The best way to fix a blockage is to stop it happening in the first place. We create bespoke maintenance schedules for schools, car parks, and restaurants to clean gullies, service pump stations and flush pipes regularly. This prevents flooding and keeps you compliant with insurance requirements.
3. Advanced Diagnostics & Mapping – Need to know where your drains go for a new development? Or need a report for an insurance claim? Or maybe you simply just need to know where your drains are, we use advanced CCTV crawlers to map your system and identify defects like cracks, roots, or scale.
4. Excavation & Trenchless Repairs – If a pipe is broken, we can fix it. Where possible, we use “no-dig” technology (drain lining) to repair pipes from the inside without digging up your car park or floors. If digging is required, our teams handle the excavation and reinstatement safely.
5. Specialist Systems – We manage private systems that are not on the main sewer line, including:
- Pump stations.
- Septic tanks and treatment plants.
- Cesspits / cesspools.
- Surface water drainage (soakaways and catchpits).

Testimonials
What Our Clients Say
“I called at 08:10 hours to report a blocked drain. A little while later, Darren rang to tell me he’d arrive in half an hour. He arrived on time and resolved the problem quickly and without fuss. He was polite and friendly throughout. Within two hours of reporting the blockage, all was well. Thank you.” Customer, Surrey
“I unreservedly recommend ASL. All the glowing reviews of ASL are true. They had to lift paving slabs to fix my drains, and I was concerned there might be unavoidable damage. I should not have worried. Liam and Richard did a superb job. Thanks, ASL” Customer, Surrey
“Darren arrived very promptly and got to work quickly. He did an excellent job and explained what he was doing. We would have no hesitation in recommending ASL Services.” Customer, Surrey
“Very efficient to book them to sort out a sewer drain blockage, and the cost was exactly what they quoted. Called before they arrived with a clear ETA. Got on with the job and sorted it out within the hour. Darren was excellent – very courteous and helpful, did more than we expected to help sort the problem out and was a font of knowledge on all things sewer-related. Given the subject matter (eeew) the whole experience with ASL was an absolute pleasure.” Customer, Surrey
“ASL recently carried out a drain repair at our house. They responded quickly to the call for help, came out and soon diagnosed the problem – tree roots blocking the drain. The remedial work on site was carried out by Lester and George – they worked hard and were very thorough. This is a long-established company that seems to know what they are doing.” Customer, Surrey
