We have recently bought a bungalow built in 1921 & is of a non standard build. We have sofar insulated 3 rooms with plasterboard fitted a new kitchen & shower room. Once the inside is finished we need to have work done on the outside.
A builder has suggested that we have a layer of bricks put on top of the current render & I am very concerned about this in case we get damp in.
There is no damp course but there are lots of air bricks around the brick skirt which appears to ventilate the property ok.
Would we be better to have the place re-rendered & if so what type of render would be suitable as there is obviously timber with a wire mesh under the current render. There is a cavity of 10 cm which is obviously serving its purpose.
