I only give one star as they actually turned up in the first place. They did not finish the job and left the premises in a terrible state with glass and debris everywhere. Despite numerous calls when they promised a return the next day,they did not return. After two and a halfweeks they finally turned up but only because they had left their ladders on the premises. By this stage we had finished the job ourselves and paid to have the debris taken away.. We would definitely not recommend this company
