Extension Builder in Somerset
My names Alan I’ve been laying bricks since I left school, over 23 year’s experience. I have done all aspects of the trade for multiple companies around the South West inc Extensions, new build houses, patios, stone work and Repointing. I have a good knowledge on landscaping, grounds works and fencing and have also done roofing and maintenance. After years of working on site and for other people I’ve decided to go out on my own. With a very good reputation in the trade and good connections I feel it’s time to do what I do best for myself. I’m fast, punctual and extremely focused and hardworking. I’ve gained good background knowledge in all aspects of building and construction but brickwork is my specialty..
