Chris has just completed a great job for us, knocking out a load baring wall to combine two rooms and installing an RSJ, with a complete replaster of walls and ceiling to a high standard. Despite coming across a few problems Chris still worked hard to get the job done in record time and to a high standard. I would absolutely recommend him and will be using him in the future!
