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 👏👏👍

Bricklaying- 24 Apr 2019
Jake and Harry did an amazing job with our front wall and fence in the rear garden. We got three quotes for the job and they were the cheapest but also came across professionally. It wasn't a straight forward job, it was was using reclaimed materials that were varying size and shapes. I was also quite particular on the look, I wanted the brickwork to match our house, they took care to match the pointing and bricks but offered advice on how we could save money whist still getting the look we wanted. They arrived everyday on time, they were reliable, honest and extremely hardworking. They also kept us in the loop throughout the work making sure we were going to be happy with the end result. I have already recommended them to friends and will use them again for our next project. Thumbs up from us!
