They had been cleaning my windows for some time and were exceptional so, when I needed my roof cleared of moss I asked them to do it for me. This was over 2 years ago and it still looks great. Not a sign of any moss, in fact the comparison between my roof and next door is remarkable. when Steve Bowie came yesterday to sort out my leaky Gutters, he had to dismantle some of the down pipe fittings to get rid of the blockage. You simply can't get that kind of service everywhere. He then cleared my neighbours gutter, which is an extension my own, so their rubbish didn't end up in mine.
