Recently following a poor surveyors report a damp specialist found high damp meter readings in the porch, bay window, loft room and under a chimney back gutter. I drilled holes in all four places collected the dust, weighed it, dried it in an oven at 120 C and re weighed it, results showed house was ‘bone dry’ % between 1.17 ams 1.78%. Damp company lost a job, sale went through and surveyor went in my bad books.
