DRAIN OVERFLOW CLEARANCE

Excellent Service. Noted they were 'Which Trusted Traders' so phoned them as I had a drain overflow. Left a message for them to phone me and they made contact by phone within 15 minutes. The problem was not immediately urgent so we mutually agreed they would call next day. They quoted me their price which was fully acceptable. They arrived on time and promptly dealt with the problem. Alex, who I believe is a director of this firm and his colleague were very pleasant and helpful - even explained the working of the drain filter. Their vehicle was modern and fully equipped. They were obviously very experienced. I am writing this review as I believe this business deserves recommendation

Alex very patiently diagnosed and solved our drainage issue that was leading to some internal damp. He was also very patient arranging the work with tenants and communicating with me as I couldn’t be on site. Highly recommended

I have used this company many times for a recurring drain issue. Alex is a very efficient and friendly guy and I never have any complaints at all. He is transparent and explains just what's going on, he comes when he says he will and does a fast and effective job. His services are also very reasonable. Thanks Alex!

I’ve used this company twice (many years apart) and both times Alex has come round promptly and cleared the blockage in my drains. The service is outstanding and work is performed to a high standard and very courteously. The charge was very reasonable too. I have no hesitation in recommending this company

Drain Blockage Removal

Alex turned up at the appointed hour ( within 2hous of a call) jetted the drain and cleared the blockage. Very professional service. He quoted a sum over the phone and charged what had been quoted with no hidden extras, which is refreshing as others quoted by the half hour and if machines were needed then there would be additional charges so the oral quote was just a starting point.

Alex and his team always arrive on time and finished the job quickly. They did a great job on my blocked underground drains and everything was working perfectly once the job was completed. Great friendly and reliable service. Thanks all.

Alex and colleague jetted a rainwater pipe to clear a blockage, but it was clear the pipe needed replacing. They undertook that work later in the week, working to a high standard and leaving the area they worked looking as if they hadn't been there. Great service delivered as they promised. Thanks!

Came to clear blocked gulley in patio. Alex arrived at the agreed time. Did the job swiftly and was careful not to track mud into the flat. Gave me good advice about getting other tenants to contribute to the bill. Invoice was exactly as quoted. Would definitely use again.
