Meet the Tutor – Joe Moriarty

If you want to learn lime plastering from someone who truly knows their craft inside and out, Joe Moriarty is the tutor for you.

Joe began his career as a plasterer, working hands-on with traditional materials long before conservation became his full-time focus. Over the years, he’s built up a huge depth of knowledge by working on some of the most prestigious historic buildings in Wales and England, moving from builder to site supervisor, project manager, and now heritage professional. Along the way, he’s never stopped learning—completing an MSc in Sustainable Building Conservation and gaining specialist qualifications in the repair and energy efficiency of traditional buildings.

Today, Joe works as a Built Heritage Monitoring and Enforcement Officer, helping protect listed buildings and historic parks and gardens. But what really sets him apart is his passion for teaching. At the Tywi Centre, Joe brings lime plastering to life—sharing not just the how, but the why. He’ll teach you how to work with lime in a way that respects both the material and the building, drawing on real-life examples and decades of practical experience.

Joe’s sessions are full of insight, encouragement, and good humour. He’s approachable, down-to-earth, and always keen to help others gain confidence with traditional techniques. Whether you’re new to lime or looking to refine your skills, you’ll come away with not just knowledge, but real hands-on ability.

With Joe, you’re not just learning lime plastering—you’re learning it from someone who lives and breathes heritage conservation.
