Six weeks after a failed job, I still have sewage in the garden so, in short, use someone else. A dreadful experience which, after two hours left me with hundreds of litres of sewage in the garden and a drain still blocked. Two days later someone from elsewhere came out and cleared it with no mess in 5 minutes. For the privilege of having Coastal not do the job, I was originally charged well over £600, later reduced after complaining.
There are plenty of drain clearance businesses out there and I would not touch Coastal Drains again with a barge pole (which may have been more effective).
Response from Coastal Drains Ltd
We received an email from you on 09/01/26 confirming that your complaint had been dealt with satisfactorily and the matter was closed, so we are extremely disappointed that you have still left us this negative review. This job was an emergency call out on the evening of Saturday 27th December. Clearly a premium rate was charged but later reduced as we could not unblock the manhole. The other company was Southern water as the block was in the public sewer pipework, which we are not allowed to perform work on. Our engineer contacted SW for the customer and was asked to wash the patio down.
