Terraced house, stone outer walled, brick inner walled front and rear. WarmFront say that it can’t be done. Struggled to get anyone on the technical side at WarmFront to explain why. Can’t find anything on the internet telling me why it cannot be done. A builder down the street said it can be done, but when he attempted to have the work done by another company, they said same as WarmFront. Any ideas ? Dunno if I’m being daft, but perhaps with it being a terraced house, would whatever “gunk” they filled the cavity with just end up trying to fill the whole block ???
