    Garage had a patio door installed by the previous residents that went the whole way to the ground. When we moved in we had this removed and a wall put in its place, this was almost 2 years ago. The patio door previously had a water ingress problem that has continued even after the new wall was built. Below are some pictures of the problem, first 3 are external, next 2 are internal. I think the ground level outside and the floor level inside are the same. The ground outside this wall is concrete.

    Not sure if this wall needs rendered or the solution is more complex than that (it certainly needs plastered on the inside). Would like any input on what the problem might be before getting contractors out to look at it. Can provide further info if anything is unclear.

    External finish of the new wall

    Bottom of the wall which is somewhat damp

    Where old and new exteriors meet

    Internal wall, unfinished but intend to get that addressed

    Damp on brick lowest to ground, this extends the length of the new wall

    Dig a trench about 400mm deep across the front of the garage and fit a 'French drain' to take away the surface water, then the ingress should be greatly reduced.
