Routine Drainage Maintenance
Prevention is Better Than Cure
We service our boilers and MOT our cars, but we often forget about our drains until they stop working.
Routine maintenance is simply the practice of cleaning and checking your drainage system before a blockage occurs. It removes the gradual build-up of silt, grease, and scale, ensuring your pipes flow freely all year round.
In simple terms: We clean the pipes now so you don’t have an emergency later.

Why Drains Need Regular Care
Even if you are careful, your drains naturally collect debris over time.
- Foul Drains (Toilets & Sinks): Build up scale, grease, food waste, and soap scum.
- Surface Drains (Rainwater): Fill with leaves, mud, roof moss, and road grit.
If left unchecked, this build-up restricts the flow. Eventually, a heavy storm or a busy Christmas period pushes the system over the edge, leading to blocked toilets, flooding, or bad smells.

What Our Maintenance Includes
We tailor the service to your property, but a typical maintenance visit involves:
1. High-Pressure Water Jetting – We use our powerful van-mounted jetters (up to 4,000 PSI) to give your pipes a deep clean. This blasts away:
- Fatbergs: Solidified grease from kitchen waste.
- Scale: Hard water deposits that narrow the pipe.
- Silt: Mud and sand sitting at the bottom of the drain.
2. Gully Cleaning – We lift the grates on your driveway or car park and vacuum out the leaves and sludge. This is vital for stopping floods during heavy rain.
3. The Health Check – While we are cleaning, we keep an eye out for trouble. We check manholes for damage and look for early signs of tree roots or cracks. If we spot something worrying, we will let you know so you can fix it before it becomes expensive.
Who Is This Service For?
While many homeowners book us for an annual “spring clean,” routine maintenance is essential for:
- Private Road Associations: Preventing large puddles on shared roads and keeping residents happy.
- Restaurants & Pubs: Managing the heavy build-up of kitchen grease and fat to stay open for business.
- Schools & Councils: Ensuring playgrounds and toilets remain safe and operational.
- Commercial Sites: Avoiding downtime caused by flooded car parks or blocked facilities.

Planned Maintenance Plans (PPM)
For our commercial and private road customers, we offer Pre-Planned Maintenance contracts. We can visit monthly, quarterly, or annually—whatever suits your site. We track the schedule so you don’t have to; we schedule a visit, do the job, and send you the report.
The Benefits to You
- Save Money: A scheduled clean is far cheaper than having to close your business because of an emergency drainage issue.
- Predictability: You can budget for maintenance rather than being hit with surprise repair bills.
- Safety: Reduces the risk of slippery, flooded walkways in winter.
- Peace of Mind: You know your system is ready to handle the British weather.

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
