I would like to say that this work was completed perfectly. They were always on time and cleaned up after themselves. The plumber was there all day and never stopped. We found them all very approachable and helpful. No pressure sales. Would gladly have them back for another job and would recommend them to others.

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.

It was a time challenge for me to move to newly purchased house as my rental agreement was due. I got Saby from personal reference. All home colour, wiring, removing old big boiler, water tank and rerouting of all pipe work. Roof repair , new two en suites construction, whole IKEA kitchen. He delivered as per our expectation and design in 8 weeks. No time waste and all material he arranged. I am very happy the way he professionally handled the work and delivered on time. I would recommend him. Make sure your design is ready and perfect. Discuss with him before start and avoid changes for best results.

Extensions- 18 Nov 2022
Jack and the team have been amazing from start to finish. Nothing was too much trouble for them. We discovered issues with our 1930s foundations, damp issues and more and Jack resolved everything without adding any stress to the project! They finished the project on time and on budget and we couldn’t be happier with the work they’ve done. What’s more, Jack, Simon and Harry are all really nice, friendly and helpful guys and a real pleasure to have on site! They completed our single story extension in a little under 10 weeks, exactly as planned. Great quality at a reasonable price and the whole process was a real pleasure! Definitely recommended!
