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.

Carpentry- 21 Dec 2025
Viktor and Michael are very friendly and professional. They were on time and the price quoted was the price I paid. I hired them to install architraves around 4 internal doors and I am very happy with their work. They made sure I was happy with the work before they left and they took time to clean up after as well. They take real pride in their work as all the joints are perfectly aligned and all the nails are sunk in to the wood so I can apply filler afterwards and paint. Viktor also made a quick trip to Screwfix to ensure he used the strongest adhesive to fix the architraves to tiles in the bathroom. I will hire Viktor and Michael in the future to refurbish my stairs and install wall panelling on the stairs wall. I highly recommend them for their honest and professional work.
