Why Rising Damp Gets Ignored Until It's a Bigger Problem
Rising damp gets misdiagnosed, painted over, and ignored more than almost any other property issue. Part of the problem is that it looks like something you could solve with a tin of paint or a dehumidifier. It isn't. And the longer it goes untreated, the more damage it does to your walls, your plasterwork, and the structural integrity of your home.
If you live in an older London property — particularly anything Victorian or Edwardian — this is something worth understanding properly.
