Are you worried about blocked drains happening again?
We're here to give you peace of mind with our exclusive '12-Month Clear Drain Guarantee'.

Drawing from our extensive experience, we've observed that most blocked drain situations can be resolved within just 30 minutes, and this includes our complimentary 'Quick Look' CCTV camera survey!
Achieve It Once, Achieve It Right.
You might wonder how we can be so confident that the blockage won't return without investigating its root cause. At ASL Limited, we have a steadfast commitment to delivering comprehensive and effective solutions.
Quality service
Once we've successfully cleared your drain, we consider the job done properly. We firmly believe in providing high-quality drainage services and it's our principle not to leave you with a drain that might clog up again after a few months. By utilizing our drain camera during the survey, we can confirm that the blockage has been completely eliminated and evaluate the condition of your drain. This valuable information is then shared with you, offering assurance that either the blockage is unlikely to recur or providing guidance on how to prevent future occurrences.
Easy to maintain
Once we've cleared your drain, it should be easy for you to maintain its unobstructed state. As long as you avoid disposing of fat, grease, foreign materials, or objects down the drain, we are confident that the job has been carried out properly, greatly minimizing the risk of future blockages.
However, in the rare event that the same drain becomes blocked again within the following 12 months, we stand by our guarantee. We will promptly return and unblock the drain at no additional cost, ensuring your complete satisfaction with our service.
