When working with a painting services provider, preparation is key. Before you get started, you may want to find out if your home contains any lead in the paint already on the walls; this would be common in older houses, and you will need to tell the painting company about this beforehand. You will also want to prepare your walls before the decorators arrive.
Cover any large cracks or imperfections with filling paste. If your decorator is going to do this for you, though, then you can take note of what needs doing for accurate pricing. Most importantly, to facilitate a smooth project, your walls will need to be free of any grease and dust; thus, it will be worth your while to wash these areas beforehand.
