Conversions - General- 19 Sep 2021
Michal and his team demonstrated utmost professionalism, quality workmanship and due diligence and I have already passed his contacts to my family and friends as a reference. M J Joinery removed internal wall, removed chimney breast and opened new doors, fitted new kitchen, skimmed entire house . The work was completed exceptional and he involved the building control in every step of the work . Michal had tidied up the house and removed all rubbishes. He hired 3 skips and made sure everything is tidy and clean . I will definitely call Michal for any future work and would highly recommend him to anyone.

Plastering- 4 Dec 2024
Ash was fantastic, turned up on time, completed the job perfectly as to what I wanted. Initially we planned for 2 days however due to lack of electricity in the apartment they couldn't finish on time, they came back in on Saturday to finish the job. They also completed some other small plaster tasks for me without question. I've already hired Ash for another job and would fully recommend. Edit on 23 May - Ash has done further other works for me including a bathroom reno and painting of all interior walls, he has gone above and beyond expectations the flat is now looking fantastic, he has always turned up on time and followed through on what he said he will do, where timescales got difficult with other trades Ash stepped up and came in on a couple of weekends to ensure the project ran smoothly. Further to this he has also offered me advice on how to do the DIY bits I have done myself and saved me some rookie errors. A+ grade contractor, worth a call and a quote.
