Bricklaying- 13 Aug 2022
Complete waste of time. Hired this tradesman a few months ago, to work on a simple brick BBQ. We had a conversation in person about the job and i informed him i would be supplying the bricks as they are "reclaimed". On the day they were to start the job, he turned up and said "oh" where are the materials, which was concerning. I had to explain our conversation in detail to point out that i said i was supplying the brick as they were reclaimed, no mention of any other material. I had just completed a huge renovation project and this was one of the final contractors to be used. Unfortunately this person is very amateur, and he then made me pay £500 for materials to be delivered. I paid for the materials and the new start date he suggested wasnt suitable, he then said he longer wanted the job! Can you believe it, he made me pay for all the materials, even though that was not agreed in person. I have dealt with over 12 different teams working on this project, and this one is the worst. No care in the word, he even sent a text said he was "quaking in his pants" about a bad review. I just replied saying, that sums everything up - totally unprofessional. Move on.

Plumbing- 7 Aug 2018
I gave this person the plumbing work for my house extension and renovation for the existing of the house, at first this person was polite and well behaved, after he was given the first instalment, his intentions became clear. The contract, which was signed by both of us, was ignored. it was allegedly written by his 17 years old son, who left them and that the man is not responsible for the contract. Whilst the man and his brother were doing the plumbing a few things which were lying around the house had gone missing, as well as the fact that he had just spontaneously disappeared for two-three weeks at a time on multiple occasions. In each occasion he had brought up excuses such as his wife had a heart attack or he had been to Poland for a bereavement. Towards the end his attitude had changed as he became more aggressive. He had persuaded me to give the last installment and promised to be devoted to the task at hand. As soon as I entrusted him with my hard-earned lump sum from my pension he took his tools and left, resulting in me having to find other tradesmen to do the remainder of the work. In his profile he advertised that he has a diploma and many other qualifications in plumbing, I have my doubts as he could not hold a basic conversation in English. This made me suspect whether he really did receive these “qualifications”. His work had many faults within it which forced me to turn to another plumber.
