How much extra do you charge for tarmac as oppossed to cobblelock and paved driveways etc? Generally bit nervous pricing tarmac as not done much of it all. On a positive note bought an fsc last yr with new pressure washer but only used it in dribs and drabs. Done a massive area of paved drive today with it and cannot believe how time efficient it is and also how much less strain it is on body compared to turbo nozzle
