I struck gold when Christophe offered to re-felt my two sheds [each aprox 6 x 2½ft]. He visited promptly to measure up, suggested they would benefit from a couple of coats of preservative [true], quoted quickly and 2 days later turned up with all the materials & a comprehensive tool kit, did a great job [including emptying the sheds, moving them to get at all 4 sides then returning & re-filling them] & took away the old felt & packaging]. In a week or so he's also going to lay a path for me.
