Late last night the thaw set in here. I noticed it when I heard "plop" into one of the containers left on the window sill, just in case. We had had no more water dripping in to the living room as long as it was frosty but now our bedroom window seal had surrendered as well so it was to work with what few newspapers we had left and some large polythene carrier bags to catch and mop up the water. Now, most of it seems to have seeped out of wherever it had been, up under the tiles, and the bedroom window at least, has dried up. So far, no wet stains on walls or carpet, but rather a lot of soggy newspaper in the recycling bin.
Chic spent the forenoon shinning up and down a ladder, like a yoyo, with kettles of boiling water to thaw the mound of ice in the rhones and at last he freed them enough to pick out the ice, chunk by chunk. That should allow the melting ice now to drain back down from higher up under the tiles as well as from the surface .
I chipped away, outside the back door, at the packed down snow, which had turned to ice and shovelled it into a pile but shortly afterwards I found that Charlie and the pups had been carrying chunks into the kitchen---another mess to clear up.
