Bathroom Fitting- 5 Nov 2019
I met up with Peter, told him what needed doing and he provided a detailed quote within days. I handed over a set off keys and basically left him and his team to get on with it! This was a time restricted job, he purchased all the material and provided all the receipts. I returned a week later to find the job completed to the highest standard surpassing my expectations. I will definitely be working with Peter again in the future and I would highly recommend him.

Decking- 3 Jun 2026
Anthony did a great job from start to finish. Having had a few quotes, some cheaper, I decided to hire Anthony for the job as his quote was fair, thorough and clear about the process, materials, time needed, I did not get this assurance from some of the cheaper quotes. He listened carefully to what I was looking to do and make some good suggestions to help achieve the look I wanted for my decking. Communication was clear at all times during the job. Once the job started, Anthony was punctual each day, organised and ensured the site was kept clean at all times. I am very happy with the decking and standard of work achieved. I would highly recommend Anthony and AJK Building and would definitely hire him again for any future jobs.
