I don't whether it is a local phenomenon to where I live but a paving contractor named Marshalls is fly posting signs advertising themselves at junctions, commercial advertising hoardings and they will screw signs to your fence without your permission. If they are doing a job they will attach signs to lamp posts and every available place close to where they are doing the job. The signs have proliferated in Cyncoed, Llanishen and Rhiwbina. When you leave Sainsburys in Thornhill there are 4 signs attached to fencing there. Last year the same happened except it was a company called Hansons and it seems to have happened every year in recent years albeit companies with different names. I must admit my drive needs doing but I can't say that their carpet bombing an area with their signs encourages me to get a quote from them. Anyone else noticed this ?
