    Floor boards never go back down right in my experience. We had a victorian property with similar damp issues. Ended up cutting a 4 inch wide trench around the entire outside perimeter of the house. Solved all our downstairs damp issues.

    Our next door neighbour did the same thing because block paving had been laid, higher than the old drive and bridged the DPC.  Creating that gap sorted all their damp problems.
    There's already a trench around the air brick if you see images

    Do you know where the DPC is in relation to the height of the air brick - Ideally, the DPC needs to be 150mm above any hard paving (concrete, tarmac, etc). Cutting away the paving and leaving a 150-200mm wide trench can pay dividends if the paving is too high. It limits rain splashing up off the hard surface and soaking the base of the wall.
    Her courage will change the world.

    Treasure the moments that you have. Savour them for as long as you can for they will never come back again.

    I believe dpc is below it but some parts of DC level with cement but it's been like this 25+ years and so far only cause this minor damp in hallway

    Bund is what I have heard them referred to although do not know if that would be common usage throughout the country.

    What would you do?

    I'd get a quote from a builder to replace the entire timber floor with a concrete slab on a DPM on Lightweight Expanded Clay Aggregate insulated filling base.

    I think that's saving the entire subfloor right now although another air brick I dug down and feel like a old air vent is below the new air brick

    If the DPC is below the level of the air brick, then you have a serious problem - The concrete will be bridging the DPC and rain water will soak the base of the wall leading to penetrating damp internally. Just because it has been like this for 25+ years, it doesn't mean that damage is not being done in areas that you can not see.

    Treasure the moments that you have. Savour them for as long as you can for they will never come back again.

    Evidently not, the expensive thing to do would be to rely on the present set up,don't let your pride stand in the way of the sensible suggestions to improve it.
