I see new window cleaners around all the time,who cares,there not taking any of my work,theres plenty for everyone!
As for B&Q ladders we all started off with them,don't knock them because they're probobly starting up a buisness and will get a set of Ramseys in a few years time,if they are undercutting they won't last long but if they are genuine guys good luck to them.
