Covid News Alert | ASL Limited Skip to main content

ASL Limited is open for business and acting in line with government guidance.

Firstly, we would like to say that at ASL our considerations are for the well-being of you and your loved ones, and of course our teams of operatives.

If you experience any drainage problems during this pandemic, our office is open and our teams are carrying out the essential work of dealing with blocked drains and emergency work. A blocked drain is not only an inconvenience, but it is also a threat to our health and, in the worst-case scenario, can cause disease or rat infestation etc. if left unattended. They may also be associated with smells indicating the presence of a variety of gases, which can cause sickness and disorientation.

You can rest assured that if we visit your property to deal with your drainage situation, this will be a non-contact procedure. Our operatives will keep their distance according to government guidelines, i.e. at least 2 metres. They will leave you an invoice which you can pay by card using our freephone number, or you can pay directly into our bank account, the details of which will be provided. An official invoice/receipt will be sent to you via email or post, together with any recommendations that may be necessary to bring your drains back into tip-top condition.

We want to share our admiration and appreciation for the heroic efforts of all the doctors, nurses, associated care staff and their families, within all care settings, at the forefront of the response to the Coronavirus pandemic and across the National Health Service. Thank you very much.

If you have a drainage issue, let us help you.

To save you precious time in any blocked drain emergency you may be having, please check if we cover your area using the map below. We can cover a 25-mile radius of our head office in Guildford.
