I know nothing about this house other than it is about 10 years old. It is detached. Down one side of the house the water doesn't look like it is draining away. The ground is quite soft and you hear the squelsh of the water as you walk down the side. When it rains puddles form. THe previous owner laid 3 slabs which are joined to the house such that when it rains the water on the slabs drains towards the house and just stays there. Where the 3 slabs meet the house there is a line of green moss about 3 inches high up the bricks. THere is also one of these big anti-weed sheets laid down the whole side of the house - don't think that is helping with the drainage. I think the previous onwner was going to slab the whole side, as there is a load of slabs piled up. They got as far as laying down sheet and placing 3 slabs. I am wondering if they have caused this issue. In the house there is a dampish foosty smell at the kitchen, this smell can also be smelled to a lesser extent in adjacent rooms. The kitchen is right next to where these 3 slabs have been laid. I have had 3 dampness people out to outside and they didn't pay much attention to outside, were more interested in inside the house and below floor. they are dampness people as well. The other side of the house has monoblock and no drainage issues. Who should I call out to have a look. Is it obvious what is going wrong here? I am fast becoming concerned, if anyone could provide a link to a company that specialise in this sort of problem i would be very appreciative.
