Hello Kath, It depends what is actually concerning you. Are you concerned about the actual contractor or the job in general? Reputable tree specialists should be trained/qualified and have liability insurance, also they will dispose of the waste in a responsible way eg take it to a registered green waste site or to their own yard. Not dump it in the forest or a layby. The other answer given (Mark Leverton) covers questions about the job in general, so i wont repeat. One thing though if the contractor is going to chip the waste on site, you might want to ask to keep some chipping for your own use. Mulch or pathway. Regards, Phil
