Landscaping- 4 Oct 2024
One word to define this 'company' COWBOY builders. Numerous issues one after another. Had to get 2nd/3rd opinion on their work to make sure I wasn't being fobbed off. Conducted loads of research which meant left being uneasy especially as a large chunk of payment was made after only 1 day of work when in fact payment was due end of completion. 1- Underestimating material costs 2- Slabs off the walkway coming loose within 2 months of being put down 3- Ignoring attempts of rectifying the flawed job 4- walkway was meant to be clear of grass and strictly shingles but grass/weed still appearing. 5- Forgot to state ground levels would be raised then creating a lie saying I had been told 6- denying and ignoring the obvious Wouldn't trust the reviews being left here and definitely wouldn't use or recommend them to anyone. Have decided to give up on trying to get them to fix their shoddy job and find someone else to fix their mess Correction - you was aware & agreed with mat delivery

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.

Restoration & Refurbishment- 9 Sep 2021
The original job for a bathroom renovation turned into a much bigger job. Raphael and his team ended up helping design and renovate the bathroom, bedroom, living room and hallway. The team helped us source all the materials including underfloor heating and an incredibly intricate mosaic tiled floor in the hallway. They provided practical advise about what was best for the space, what would work within our budget and what would be easy to live with. For example, the team installed underfloor heating in the living room using wood effect herringbone ceramic tiles which would help get the maximum efficiency out of the underfloor heating whilst giving us the wooden flooring look we desired. Raphael and the team were excellent throughout delivering high quality work and we were more than happy with the final results. I would highly recommend Raph and his team.
