A mason helper performs simple masonry duties that require less skill to enable more experienced masons to focus on the complex tasks of the job. As a mason helper, you can work for masons in various specialties, depending on how you want your career to progress. A brickmason builds and repairs walls, floors, fireplaces, and chimneys. A blockmason installs the same structures, but with concrete block and precast masonry panels. A stonemason works with natural-cut and artificial stone, like marble. Your responsibilities are to prepare and clean tools, materials, and other supplies, as well as lay brick or stone and mix mortar.
