As a tile subcontractor, you work under contract from a construction company to provide services related to tiling. This includes work on residential and commercial buildings where you install tiles or other ceramic materials. Other tile subcontractors work to repair broken tiles or install replacement pieces. Traditionally, tiling is commonly used for floor material, as the material for a kitchen wall backsplash, or in a bathroom, especially in the shower. Your duties include taking measurements, preparing materials, installing tiling, and working with grout.
