Back up the Ladder

We have had one or two problems recently with rainwater when we have violent downpours.  So we've finally decided it's time to fit some guttering.  One of the reasons we've not done this before is that I'll have to do some jointing of the tops of the walls where our builders 'made good' 6 years ago when they were renewing the roof!  However, 'time and tide ...' has caught up with me and so ....

But .... before I can fit the guttering and downpipe I'll have to get into our water 'citerne', which is under our terrasse, to check/make good the walls.  Our builder was concerned that water could get through into the klitchen.  We'll see!!!
