  • Hi I’m Mark I started my own company around 10 years ago after years of working for other people. Starting trade was plastering which is still my favourite trade and what I love to do. I have done some commercial work but mainly domestic. My company has grown over the years and taken on lots of projects from a 200 year old listed building converting it from a pub to restaurant to Modern day homes. We undertake any works from plastering a single wall to extensions, refurbishments, kitchens, bathrooms and everything in between. I like to work close with my customers for that personal touch in making your vision/dreams come to reality. We are always looking at new products on the market which helps give the best results for your projects and can save time and cost which helps to stay relevant and competitive. I work close with a great architect and have a large knowledge and understanding of drawings and structural design so if you’re just starting your journey we can take care of it all from start to finish. So what ever your project let us make that vision come true.
