Cavity Wall Insulation Problem

Options
I really hope someone can help me.

I am in the process of applying for cavity wall and loft insulation and the surveyor came to the house on Monday.

Everything is ok with the loft, its the cavity wall thats the problem, when he was here he said that the external vents might not be suitable for cavity insulation and that he had never seen anything like them before. He left saying that he would need to consult his manager and let us know.

Well he rang last night and said that we cant have the cavity wall insulation because of the vents, when I asked why he just said they are not suitable, thats it.

There are 2 vents on the external wall and I think these are because we have wooden floor boards. I dont have any gas fires or any sort of fires for that matter so I can see that I would need anymore ventilation. My neighbour has the same vents and a gas fire and their house was insulated 2 months ago. I have asked for a second opinion and am waiting for him to call me back

Does the refusal to do the insulation sound right?

    Yes. Can be normal. Sometimes installation can result in damp spots!

    As stated a problem but you only want one answer. You want it installed. So as Andy stated, get a second opinion.

    This may be a blessing in disguise. There was a feature by Dom (out of the TV series "Don't get Done, Get Dom") on The One Show on the BBC. It suggested that cavity insulation may allow water and damp to penetrate to the inside of the house. It's worth looking into this before proceeding.

    It could be that there is no means of sealing those vents from the cavity, which would result in the cavity fill material just coming back out the vents when they try to instal it.

    As an example if you put an extractor fan in, you would put a hole through both walls, but you'd line that hole with a tube, so if they filled around that with cavity wall insulation the tube would stop the material getting either into the fan or out through the external hole. There are probably some vents which cannot easily be sealed off this way.
