I have an old stone built end terrace house (C.1880) where the walls are double skinned with a loose rubble infill.
I have discovered some nasty damp in the rear wall which has rotted the MDF skirting boards which were fitted about 15 years ago. The plaster and render seems mostly OK, apart from a small patch of blown plaster about 300mm wide x 200mm high in the lean-to kitchen extension, and the corner beading on the kitchen door opening has gone rusty.
Upstairs, on one of the windows in the rear wall the corner beading has also gone rusty, which suggested it's something other than, or as well as rising damp.
There was a leaking fitting on the gutter, so when I was up there the other day fixing that, I had a peek under the tiles and discovered that the felt has rotted back to the fascia and has sagged. You can see water marks where it has pooled.
I've bought some felt support trays which I will fit soon, as I think that water is leaking from the felt into the wall and then it is dripping down to ground level causing the damp.
I was wondering about DIY rising damp products available like creams and rods and was wondering if they are effective. I don't really want to hack off the plaster and render though if I can avoid it as it mostly seems good, but was wondering about using something like that as a 'belts and braces' approach.
Bit of a ramble so apologies, but wondering what you guys think?
Thanks in advance for any advice.
