Can anyone help please? We recently moved into our current house, which has a kitchen extension on the back. The left kitchen wall is on the boundary to our neighbour's land, and it is very damp. Every time it rains a bit more plaster falls off it:-; A couple of excellent brick specialists have been doing some work for us. They identified the cause of the damp as the concrete render on the outside of the wall, which was cracked and letting water in. It is a solid wall (built around the turn of the last century), so they suggested taking off the concrete and replacing it with lime render. We asked permission from our neighbour, as they would have to access his garden to do the work. After much discussion he very reluctantly agreed, but has threatened to sue us if any of his plants are damaged by the work. I have promised to buy him any replacement plants if necessary. The builders are half way through the job, but have identified another problem. The decorative edging of the neighbour's concrete patio, and the soil of the flower bed beside it, are right up against our wall and above the level of our kitchen floor. A damp specialist has identified that this is blocking the internal damp proof course that we have in the kitchen, causing damp on the wall. He also said we probably need to get the wall injected externally, to stop damp rising up from the ground. This work would mean asking our neighbour if we can cut a trench 12" away from the wall through the patio and his flower bed and filling it with shingle, to let the wall breathe. I'm pretty sure he's going to say no. But we have to do something, as the brickwork is crumbling from the water damage. Can anyone help please?
