We had been advised (and quoted for recommended work), by another company, that we should remove dry lining from a damp interior wall, and the concrete render from the outside of the wall. The outside should then be re-rendered, using a lime-based render. Either this or, at the very least, the gap between the dry lining and the wall should be ventilated. So we called in Timberwise with a view to getting a second, of a total of three quotes for the work. The Timberwise rep came, and spent some time examining, and taking moisture readings from, the dry-lined wall. He then told us that there was no significant problem, and that no remedial action was needed. He could have jumped at the opportunity for work for his company (and, presumably his own personal commission?) and we are very grateful for his honesty. We have other damp problems, and Timberwise will be the first company we contact about these.
