Flood Prevention & Maintenance
Stopping Trouble Before It Starts
Nobody likes wading through a flooded driveway or worrying every time the weather forecast predicts a storm.
At ASL, we believe prevention is always better (and cheaper) than the cure. This section covers everything we do to keep your drainage system healthy, clean, and ready to handle whatever the British weather throws at it.
In simple terms: We clean, check, and maintain your drains so they don’t let you down when you need them most.

Why Maintenance Matters
Drainage systems are easily forgotten—until they stop working. Leaves, silt, and mud build up over time, slowly choking the flow of water. If left unchecked, this leads to:
- Flooding & Pooling: Giant puddles on driveways, car parks, or roads.
- Property Damage: Water seeping into foundations or causing damp.
- Safety Risks: Slippery surfaces and hidden hazards.
- Emergency Bills: Paying for urgent repairs that could have been prevented with a simple clean.

Our Prevention & Maintenance Services
We offer a range of services designed to keep things flowing. Whether you are a homeowner, a private road association, or managing a school, we have a solution for you.
1. Flooding & Pooling Solutions – Fixing the Standing Water. If you have a patch of ground that always floods when it rains, there is a reason for it. It might be a collapsed drain, a blocked soakaway, or simply the wrong ground level. We diagnose the cause and install the right fix—whether that is a new drain, a diversion, or a better soakaway.
2. Gully Sucking (Cleaning Road & Driveway Grates) – The Heavy-Duty Clean. Road gullies are the metal grates you see at the side of the road or in car parks. They catch rainwater, but they also catch leaves, mud, and litter. When they get full, the road floods. We use powerful vacuum tankers to suck the sludge out and jet the outlet pipes clean.
3. Routine Maintenance & Jet Cleaning – Scheduled Care for Peace of Mind. Ideal for Private Roads, Schools, and Commercial Sites. Instead of waiting for a blockage, we visit on a schedule (e.g., every 6 or 12 months) to flush the drains and empty the gullies. It keeps your site compliant and operational year-round.
4. Winter & Storm Preparation – Be Ready for the Weather. Autumn leaves and winter storms are the biggest enemies of drainage. We offer pre-winter checks to ensure your gullies are empty, your pumps are working, and your soakaways are ready to handle heavy rainfall.
Who Is This For?
While homeowners often use our flooding solutions, our maintenance plans are especially popular with:
- Private Road Associations: Keeping shared roads clear and safe for residents.
- Schools & Councils: Ensuring playgrounds and public areas are safe.
- Commercial Sites: preventing car park flooding that could drive customers away.
- Facilities Managers: Fulfilling compliance and safety obligations.

The Benefits to You
- Save Money: Regular cleaning extends the life of your drains and prevents costly emergency callouts.
- Safety: Reduces the risk of accidents on slippery, flooded surfaces.

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
