Service was professional and efficient. From the off they knew what they were doing - erecting scaffolding, protective groundsheets, using air compressor, rubbish removal - the guys worked almost non-stop. Polite, friendly crew, grateful for their refreshments on a hot day. Tidied up for 2nd day's work when Bruce attended and roof and garage finished and sprayed with biocide - warning us re the effect of that on plants and sorting down pipes to water butts etc. To alleviate any disasters! All in all would thoroughly recommend Moss Off Roof - finished effect impressive - on a 60 year old roof!
