Which trade to diagnose wet sub floor under suspended wooden floors

The ground floor in my 1930s house in Bromley is suspended wooden floors but some rooms and the garage is solid concrete. When it rains a lot, it smells damp and wet at the front of the house. I’ve taken up a floor board in a few places, and I can see the subfloor (40cm below floor) is wet at the front of the house. My question is how can I get this sorted? I want to post something on mybuilder but which trade to I ask for? Groundwork? Damp? Paving? Also I can see 5 sub floor air bricks from outside the house. If I want to have extra air bricks added which trade do I ask for? I’m guessing an angle grinder will be needed to remove a brick and an air brick inserted. Would I need a bricklayer or some sort of specialist? Some extra info: the driveway at the front of the house is sloping down to the house, but there are some long drains in front of the house. I don’t have raising damn at the front of the house, I had it around the back and have got that sorted. Also, I think that the outside ground level is higher than the sub floor.
