We’ve had multiple jobs done by Silviya. The first was a small extension and downstairs and partial upstairs refurbishment with new kitchen and 2 bathrooms fitted. This large job was completed within 16 weeks and looks exactly as we hoped. Given the extent of works we moved out for the build. The second was the construction of an outbuilding and garden redesign (patio and astro fitted). Again the results are great. We lived in during this project and I worked from home without disturbance. The latest has been the re-fit of new windows, front door and fixing the front render. Again, the results are very professional and minimal disturbance while the work took place. Will definitely use him and his team again, should we need any more building work and recommend them to others

Carpentry- 29 Jan 2026
I contacted Ekland and his brother Bes for some light refurbishment. I was so impressed with the work and speed that they ended up doing all the works I intended to do. Starting with latex screed, flooring using LVT system, architraves and skirting boards, installation of 9x heavy duty fire doors, carpets in 2x bedrooms and finally decoration. Prices were very reasonable considering the time and effort they put into installation but not only that, as I am a first time buyer they advised me on design as I didn’t really know where to start. They are honest and reliable, where I tried to save money they said it was not the right thing to do and took additional hours to make something right without a hidden extra. They turn up at 8am everyday and so easy to work with, I left them the keys to my flat and I didn’t need to check in on them at all. If you are thinking to do any refurbishment and are either hesitant or not knowing where to start these are your guys. 5* to Vukaj and thank you!

Tiling- 16 Feb 2026
Luis did an excellent job on my bathroom. He had to do a lot of prep work before starting the tiling, including rebuilding the floor and repairing the walls. At every stage he explained what needed to be done, ensured that I wanted to go ahead, listed the materials that would be needed, and the cost. It made a huge different to me that Luis was willing to source and purchase all materials; he checked in with me from the suppliers as to choice and cost, and sent receipts for every penny. I cannot recommend him highly enough, for his knowledge and expertise, his honesty and hard work, and also for being such a lovely person, nothing is too much trouble. I am delighted with my new bathroom, and am planning more home improvements with Luis, when he is free again!
