We only have one outside wall but, at the moment, it’s damp. I’m investigating the different causes and suspect that we’ll need either new gutters or repointing and sealing of the wall itself (probably both). Since we only have one outside wall, I thought I might as well go the whole hog and get cavity wall insulation on it too at the same time - hopefully to prevent the condensation forming on the inside of the wall (where the cold moisture in the bricks meets the warm house) and to improve the general warmth of the house. (I thought about getting cavity wall insulation on the other sides of the house too but thought the neighbours might complain about me filling their living rooms with shredded fibre glass.)
Anyway, exploring the cavity wall insulation option, I ended up on the Energy Saving Trust’s website. They’re a “a non-profit organisation, funded by government and the private sector” but I didn’t realise quite what the latter entailed until I gave them a call.
