Insulation escaping

50Twuncle

We have cavity insulation beads escaping through air bricks of our semi..
The house was insulated 20+ years ago by a now defunct company - it was done before I bought the property - I don't believe that much insulation can be left in place - it is glued around the window/ door frames (I know that, from the replacements doors & windows that we had done, 5 years ago
Is there anything that can be done to remove the last dregs - what about the glued bits ?
Is there any point ?
Is it worth getting fibre insulation blown in ? (My OH believes that it causes damp)
Is this available free for someone on disability benefits ?

Your OH might be right too, but no one can say, because we can't see the house, its level of exposure, or the state of things inside the cavities.

If the vents had been constructed properly, there wouldn't be an opportunity for the beads to escape, so there's one clue. When we built a cavity wall last year, the vents were connected to ducts, which take the air to where its needed, under the floor. Cavities should be only need smaller weep holes/inserts.

I doubt if all the beads have escaped, and having a mix of beads and blown fibre probably isn't a great idea either. Personally I'd be inclined to leave things as they are.See what others with more experience than me say.

I would live with it, but have a go at rectifying the air bricks/vents. You may have screw on covers on the inside wall so remove these and make good where the beads are. Expanding foam would do the job - a gun and can would be around £25. If you terracotta bricks and no cavity liner then a bit more work would be required. Basically break out the air brick and then afterwards fit a new one.
