Flooring contractors install, replace and repair floor coverings in homes, offices and other buildings. They may work with carpets, vinyl, laminate, engineered or solid wood, and floor tiles, depending on their skills and the project. Some businesses supply materials as well as fitting them, while others install flooring chosen and purchased by the customer. Work can range from a single room to larger commercial or refurbishment projects. Before fitting, contractors typically measure the area, advise on suitable materials and check the condition of the subfloor. Preparation may include removing old coverings, smoothing or levelling the base, laying underlay, and making adjustments around doors, stairs and fixtures. They cut and secure the flooring, finish edges and joins, and may also carry out repairs or replace damaged sections. Customers can usually expect guidance on care and cleaning, as requirements vary between flooring types.
