George contacted me within hours of my posting the job and visited the next day. His quote was reasonable and he stuck to it. He arrived when he said he would and was meticulous in carrying out the requested job, clearing up afterwards. He is skilful and courteous. I will have no hesitation hiring George for other tasks in future and recommend him wholeheartedly.
