*****5 Star service and pleasant mannered reliable gent. Highly recommend! Not forgetting the price, unmatchable! Nearly fell for 2 other scammers who had quoted a figure multiple times Stephen’s and who were lacking his professional equipment. Glad I waited. Thank you Kleanios, we can rest easy that the small tree has been uprooted from our back guttering lol! More...
