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

Emergency Blocked Drain in Kingston – Structural Lining Solution

One of our drainage engineers, Darren, attended an emergency blocked-drain call in Kingston-Upon-Thames after the customer reported gurgling noises from the toilets and slow-draining sinks throughout the property.
Although Darren lives and works out of the Ashtead area, he also works from our Guildford depot and regularly attends drainage emergencies throughout Kingston, Weybridge, Ashtead, Dorking, Merstham and Horley.
The Kingston job
When Darren arrived, he began by inspecting the drainage system through the inspection chambers located within a small rear yard.
The first chamber was holding a high level of water. Darren carried out a quick test using his drain rods. As pressure was applied, the water level dropped away, only to slowly return to its previous level. This suggested there was a restriction further downstream.
Moving to the next inspection chamber, Darren immediately found evidence of a common drainage problem. Fat, grease and oil were floating on the surface of the wastewater.
Using his rods again, Darren encountered significant resistance. After carefully applying further pressure, the blockage suddenly released. Water levels dropped quickly, and gurgling could be heard throughout the drainage system as normal flow returned.
As part of our service, Darren then carried out a CCTV drain survey (called a quick look-see) using one of our inspection cameras.
The camera footage showed that the interior walls of the drain were heavily coated with grease. Darren used a jetting machine to thoroughly clean the pipework before carrying out a second CCTV inspection.
Once the pipe was clean, a more significant issue became visible.
Several open joints were discovered within the drainage line.
This is a common cause of recurring blockages. Wastewater can collect at uneven joints, allowing grease and debris to accumulate over time. The evidence was clear: fat deposits were visible not only on the sides of the pipe but also on its roof, indicating repeated surcharging and slow drainage over a long period.
Darren explained the findings to the customer and discussed the available repair options.
Because the joints had not moved too far out of alignment, the most cost-effective long-term solution was structural drain lining. This method would seal the open joints, strengthen the pipework and create a smooth internal surface to improve flow.
The customer agreed with the recommendation.
Darren submitted his findings to our office, and a quotation was issued the same day.
The blockage clearance, CCTV survey and pipe cleaning were all completed in less than an hour.
One week later, our lining team returned and installed a structural liner to complete the repair.
The customer was delighted with both the speed of response and the efficiency of the work carried out.
During the visit, the customer commented:
“How can you do this job? It’s so messy and smelly.”
Darren smiled and replied:
“It’s a team effort. It’s not just me.”
The successful outcome was only possible because the drainage engineer, office team and lining crew all worked together to diagnose the problem, provide a solution and complete the repair quickly.
