I now no longer have an overflowing drain outside the bathroom/kitchen: man has come and cleared it out, removing two stones, twigs and loads of nasty sludge - the hardest part of the job was disposing of that. We suspect the stones had been on the drain covers, which otherwise fly away in the wind, being flimsy plastic, and got dislodged in a high wind. That would explain the blockage. It's also the first time it has had a pressure hose onto it so I suspect it's the cleanest it's been for years. I also got him to quote for the conservatory door, as I only have one quote so far.
While the builder was here I spent some time sorting things in the sitting-room (neglected for a while) so as to be near at hand. There's much to be done there still ... but first on the list is the washing up. (Neglected while out in Croydon, but I think it's happening faster than I create more.) Again I have done a job which I have been meaning to do for weeks - putting steriliser in the washing up bowl. Soaking tin cans leaves a nasty grey residue, and the steriliser bleaches it. Given that I often have washing up soaking in there, sterilizing is something that's a good idea for itself.
