It is always best to choose a local decorator near where you live. He or she will be a stones throw away from your home / business premises, so they can get there early to start the job and easily get to their local trade paint supplier to pick up any materials they may need to finish the job on time.
An added bonus is that you will be supporting local business in your area, who will in turn be spending the money that they earned from you on other local businesses, so it’s a win-win situation all-round!
