Trif was very quick to reply (to dismantle an old wooden shed and build a new plastic one). He arrived promptly and his quote was very reasonable. He kept me updated by text before the date of the work. He and John worked very hard without a break, even though I offered tea/coffee! I found him to be a very pleasant, likeable fellow who explains everything and provides helpful advice. I've already asked Trif to carry out further work and would happily recommend him to others.
