We aim to address drainage emergencies within one hour. For non-emergency drainage unblocking we offer flexibility with bookings, to allow you to book when best suits you. The length of the service varies depending on the blockage as well as the cause behind it.
If you were faced with a blocked drain and after it’s been unclogged you ask yourself ‘’Is there a way to prevent this in the future?’’, This is what you should avoid putting in drains to try and prevent blockages from happening:
Water that drains slowly and an overflowing toilet are two of the most evident early signs of a clogged drain. However, sometimes symptoms of a clogged drains are less evident. For instance, you could smell sulphur or other unpleasant odours, or you might even hear gurgling. A drainage survey is your best bet if you are not sure.
CCTV Drain surveys usually take around 1-2 hours to be completed, this depends on how complicated the issue is. With underground drains it is usually more difficult to identify complications without a CCTV drain survey, which is why we recommend a CCTV drain survey in order to diagnose your drainage issue accurately, as it allows us to see underground.
Don’t wait for it to get worse. Call now — an engineer can be with you within the hour.
