Restoration & Refurbishment- 8 Jan 2026
I’m extremely happy with the work carried out by Arindo @ Altd Carpentry. From start to finish, the refurbishment was handled in a very professional and organised manner. The work was completed on time, exactly as agreed, and the quality of workmanship throughout the house is excellent. Everything from the kitchen installation, flooring, tiling, carpentry, electrics and painting was done to a high standard, with great attention to detail. Communication was clear throughout the project, and any questions or small changes were dealt with promptly and without fuss. The site was kept tidy, Arindo was respectful, and it’s clear he and the team take real pride in their work. I wouldn’t hesitate to recommend Altd Carpentry to anyone looking for reliable, skilled, and trustworthy builders. I would happily use them again for future projects.
