Carpentry- 19 Sep 2015
Not only was Ian's quote to do the loft conversion very reasonable, he was very reliable, tidy & very helpful when we had a difficult situation. The work was done in a quick time, when he said he was going to be on site he was, at no time did he let me down. The standard of work was excellent, I would recommend Ian & wouldn't hesitate to use him in the future.

Carpentry- 14 May 2026
Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

Extensions- 15 Dec 2021
Valdemar and his team of workers were outstanding. I have never known builders to be so thorough, honest and just generally nice people. They can be trusted and gave honest opinions. They were in tune with the building control requirements and worked very hard always arriving on time and working solidly throughout the day. They may be a bit pricey but you definitely got what you paid for - First class workmen ship.

Extensions- 23 Feb 2020
We hired Arra brickwork to complete what looked like a straight forward side extension, this soon became very complex due to the angle of the build and the roofing. Whilst we had our own expectations, Aushra was very helpful in presenting more ideas and suggestions in line with what we wanted. She even went as far as building sample model to show us what the build would look like. We found Arra brickwork - Aushra and Authur to be genuinely nice people, they are very polite and very tidy workers and put in so much effort to complete the build, even when we didnt expect them they were there working hard. We had full visibility of spend as Aushra was prompt at letting us know how much materials would cost including the initial quote for the build which was reasonably compared to what we had previously been quoted. We could not ask for a more trustworthy team of builders who cares about what they do and I will not hesitate to hire Arra Brickwork again for any more projects.

Extensions- 25 Apr 2020
Financial restrictions meant we had to change from an extension to simply improving the existing house. I gave Vlad a call on a friday and his army was ready to start the very next Monday morning. All would have been finished in less than 2 weeks but the unexpected Covid-19 lockdown on 23rd March meant that supplies were harder to get. Very pleased with our brand new house. Good job done on new Electrics, Kitchen, Bathroom and plumbing and he even helped fix our D.I.Y furniture at the end. Will definitely use VM on our next project.

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

Decking- 29 May 2020
Started on time and completed the decking extension & renovation to a high standard. Ensured that small details like cuts around poles etc, were finished properly and not left with gaps. Next time I would confirm that clearing rubbish is part of the quote, but highly recommend Przemek for quality finish.
