Good evening,
I'm suffering problems of black mould in the upstairs rooms of an early 1930's semi-detached house, which appears to have worsened since we had double glazing installed around three years ago.
I've recently had a survey done by a damp proofing, woodworm & dry-rot company, and they have suggested that it would be advantageous to have a Positive Pressure unit installed on the landing ceiling, coupled with passive ventilators in each room, venting through the outside walls.
I was also considering cavity wall insulation, particularly as one 3m × 2.5m bedroom is very cold all of the time, (it's over the front porch) but I've been told that whilst the ground floor has cavity walls, the upper floors are 9 inch solid brick construction. Out of interest is this typical for the year of the property?
The quotation doesn't seem excessive, but I'd thought I'd seek your opinions before proceeding.
Thanks in advance.
