    Cavity wall insulation removal

    Cavity wall insulation removal 16th Jul 17 at 1:06 PM

    We had cavity wall insulation installed (loose wool fibre type) in 2007. Around 2015 I started noticing severe damp problems in the living room only. The damp was either side of the window 2metres high including at the corners of the room from floor up. I re-rendered the outside wall and during that time I believe I found the problem (decayed mortar above the window frame, had holes). The damp problem was considerably reduced.
    I was just putting skirting on recently and noticed the inside bricks to be wet (some damp patches and salt on plaster too). Luckily I have a vent on the wall due to an open fire. Took the vent out and pulled some insulation out, which is wet but not dripping with water. There is some debris in the cavity too. The insulation material appears to be dry/dryer 1 metres above the ground.

    What I would like to know is:
    - Can I just pull out the wet insulation from the bottom and hope this will sort the potential bridging/damp problem?
    - Or should I extract all of the insulation to prevent cold spots, which may lead to damp/condensation etc?
    Will appreciate any advice on this please. Thanks very much.

    Contact ciga to see of it's covered by their guarantee. Then they should come out to test if it's wet and possibly remove it...
