Kitchen Fitting- 17 Sep 2026
Vincent recently fitted a new kitchen, hung interior doors, and installed architraving in our home, and his work was absolutely excellent. He has a fantastic eye for detail, resulting in a flawlessly fitted kitchen and perfectly aligned woodwork. He was professional, tidy, and hard-working from start to finish. If you need a reliable, top-tier carpenter, I cannot recommend Vincent highly enough!

Extensions- 22 Dec 2022
Imran is a contractor who is personable and is trying hard, but at the end relies on different teams of builders to carry out the work. His knowledge of building work appears at time limited. In our case, this has often led to poor communication/hand-over, extensive delays and often poor (if not careless) craftsmanship. Very stressful. We now have builders (family business) finalising our project.

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.

Bathroom Fitting- 6 Mar 2026
What a great team! Muneeb and his team finished the job in time, turned my tired old bathroom into a wonderful new space. Price quoted was half what we were being quoted by others. Muneeb just focused on this job rather than many others who leave the customer waiting whist doing multiple jobs. All materials used are top quality and nothing was too much for him. Muneeb kept variation minimum and agreed details in advance. Thank you Muneeb and team
