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.
