As the title says...

Today the neighbour lit their burner and shortly after I entered my lounge with an open fireplace to find a level of smoke about knee high floating infront of the fireplace.

Never happened before.

Recent survey said the chimney has damp potentially from a crack.

Both our vent and neighbours vent are aligned next to each other on the stack.

I've put a chimney blocker in on my side (those wool things to retain heat when fireplace not in use) to try to block further smoke.

I'm worried about carbon monoxide and everything else associated with smoke entering our living room - particularly so with a pregnant wife and a toddler!

Any ideas please??
