Painters and decorators London are professionals who improve the look and feel of homes, offices, and commercial buildings. Their work includes interior and exterior painting, wallpaper installation, and decorative finishes such as wood staining and varnishing. Before painting, they prepare surfaces by filling cracks, sanding walls, and repairing damaged areas to ensure a smooth and long-lasting finish. They also help clients choose suitable colours and paint types based on the space and lighting.
