Hi
I understand that installing cavity wall insulation can lead to damp problems I'm wondering if cavity wall insulation can cause the following damp problem
On the south east corner of my detached house at the dpc level and slightly below I have a damp patch it extends for approx 6 bricks horizontally and up to 3 bricks vertically but there is no apparent damp inside.I'm assuming that the dpc has been laid properly as the house is now 30 years old and this never appeared until the cavity wall insulation was installed.
Any comments would be appreciated
