“It’s catching on” he tells me. the “He ” in question is Terry, who had started a new business of clearing gutters. New to him, but also new in how he does it, as Terry uses suction to pull out the muck and old leaves! So no ladders mean no 2nd person to help, and much less risk of an accident. He works in St Albans, and in parts of Hertfordshire and his number is 07821 655203.
