We moved to our house about a year ago and it has a lovely blocked paved drive, probably done about 4/5 years ago. It was a bit grimy and dirty so I used a pressure washer to clean it earlier this year.
I have replced the sand between the blocks, but still have a recurring problem with moss and weeds! Can anyone recommed a treatment (available at B&Q or Homebase perhaps) that will kill them off for me?

Any good weedkiller will do, but it's not a permanent solution. We normally use Sodium Chlorate, because it's cheap, it's available in bulk and it works, but you could use 'PathClear' or 'Weedol' or anything like that. Generally speaking, a treatment will last for about 2-3 months during the growing season, so you'd need to treat in, say, March, early June and again in September.
For a permanent solution, the only real option is to use a paving sealant, and for that, your paving needs to be in tip-top condition before you apply the first coat; that means clearing all the weeds, giving the entire pavement a damn good cleaning with the power washer (at a shallow angle, of course! ) and have all the joints topped up with jointing sand.
