Businesses in painting and glazing carry out decorative painting and related work, as well as supplying, fitting or repairing glass in homes and commercial premises. Painting services may include preparing surfaces by cleaning, sanding, filling cracks and applying primers, followed by paint, stain or protective coatings to walls, ceilings, woodwork, doors, metalwork and exterior surfaces. Some businesses also undertake wallpaper removal, wallpapering and other finishing work. Glazing work can include measuring and fitting glass in windows, doors, partitions, shopfronts and conservatories, and replacing cracked or broken panes. Depending on the business, customers may also find double-glazed units, safety or laminated glass, mirrors, splashbacks and decorative glass. Work can range from small repairs and reglazing to larger installations, with materials and methods chosen to suit the opening, building and intended use.
