Kitchen Fitting- 1 Jan 2023
I have to say that Tyrone who carried the work out for is very professional and commendable. He was always on time and eager to get the work done. His attention to detail is simply quite impressive. Having completed the work i was rather surprised to learn that he called back the next day only to complete a very small detail that he forgot. A small detail that was not exactly noticeable, thus leaving us with satisfactory results. I’m certainly going to recommend their services to anyone who might require their services. Many thanks 👏👏👍

Restoration & Refurbishment- 5 Apr 2025
Where do I begin? So Alex and his team has pretty much renovated two flats including external work such as roofing. The work involved was quite challenging as the building has a lot of damp / mould / leaking issues. Alex’s attitude towards resolving every matter was exemplary. He would take his time to explain his strategy to tackle each and every problem in a very metholodical way. I have never seen anything like it. I am so pleased with Alex’s work and so are my tenants who live in the flats. I would highly recommend Alex, especially for tougher jobs!

Carpentry- 11 May 2024
Matt went above and beyond replacing our old battered worktop in our kitchen and fitting new skirting boards. He was prompt, clean and pleasant and the work was spot on. Often its difficult getting work done that isn't straight forward, but Matt always came up with the best solution. He's coming back to do some more bespoke carpentry based work and I have no hesitation recommending him for any jobs you have.
