My father had rockwool blown into his bungalow's cavity wall around 10 years ago. There is evidence of condensation damp at floor level on the north and west facing external walls, and I suspect there was already air-blown sand within the cavities when the rockwool was added. I have read that the original guarantee would cover the removal of the rockwool because the building is within a mile of the west coast of England, and also it's replacement with a suitable alternative insulation material. Is this true? I have the original installation warranty certificate. If the installer is no longer trading, is the next call to CIGA?
There are complications; the west facing wall has since been rendered with self-coloured K-rend, notoriously difficult to patch, though luckily it is going to be practical to remove inner leaf blocks along that face for the purposes of cavity clearance if necessary as the whole bungalow is about to be refurbished.
Have any of you pearls of wisdom to add?
Kind regards, MM
