Oh dear...

The (Grade 2 listed) front door, which was painted earlier this year, is showing signs of stress. The recent hot sun hasn't done it any good!
Next time, I won't bother with decorators - I think I'd make a better attempt myself!
At the moment I am waiting for a reply from the firm that did it. I got onto them much earlier, when it was all put down to sun and heat, but now it's much worse, and winter is coming!
