I had what I thought was one blocked gulley drain and called a few plumbing firms for quotes. LocalPlumber-UK Were not only 10% cheaper but also available at times that suited me. Their plumber Ricky came out and noticed a second drain was also blocked. Without hesitation he unblocked this for me too at no additional charge. They were so good that when my brothers sink was blocked he used them too. Again they were far cheaper than he had been quoted elsewhere and unblocked the sink and made sure that they left no mess!!! I would definitely use them again and cannot recommend them highly enough.
