Highly recommend Ben for plumbing and rendering work! He did a fantastic job — everything was completed to a high standard, on time, and within budget. Very honest, easy to communicate with, and offered practical solutions without upselling. His pricing was fair and transparent, and the quality of work speaks for itself. It’s rare to find someone so reliable and skilled these days — will definitely be using him again!
