Painting & Decorating- 6 Apr 2026
I had a very positive experience working with Konstantinos. He is personable, reliable, professional and excellent at co-operating throughout the process. He repainted my entire flat/walls/ceilings to a high standard (and sanded down) he also helped address a few additional repairs along the way. The finish is clean, fresh, and has completely transformed the space. He was thorough and ensured everything was completed properly and on time. I particularly appreciated his attention to detail and his proactive approach in taking care of things I hadn’t even noticed. I would happily recommend Konstantinos and would work with him again in the future! Thank you

Kitchen Fitting- 7 Jan 2021
My experience with Leszek was entirely positive and I wholeheartedly recommend him. I had recently moved property (converted victorian flat) and required a new kitchen installed, shelves built, radiators replaced, painting throughout and some changes to electrics. The work was undertaken around October 2020. Leszek completed the work to a very high and professional standard and I am really happy with the end result. He was easy to get on with, good natured and commutative which made the whole process easy and less stressful for my first experience in home improvements. Leszek was always happy to answer all my questions and further explain the fine detail from electrics to kitchen installation. When small problems arose, he always had a couple options ready to discuss and called promptly to keep me up to date. The kitchen installation is perfect which also included tiling a backsplash. Lezek built some lovely selves in the recesses either side of my fireplace which look brilliant and very smart. The painter and his work was really professional and speedy. Snagging was dealt with and two neighbours independently and proactively commented that the work was done with minimal disturbance to them. From quote to completion it was all in all an excellent experience!

Carpentry- 8 Apr 2026
I’m really happy with the work carried out. He came in to fix my steps after a previous builder had damaged them and left them unstable, and the difference is night and day. Everything now feels solid, secure and properly finished. He also fixed the skirting boards and installed my desk, all to a very high standard. What I really appreciated was how professional he was throughout and the advice he gave along the way, which showed real experience and care for the job. Overall, a really high-quality finish and a great attitude. I wouldn’t hesitate to recommend him.
