Can anyone help please? We have recently moved into a house in Wallingford, and have discovered Japanese Knotweed in the garden. We understand lenders will not offer a mortgage on the house while the knotweed is there, which means we would find it very difficult to sell. It also seems that the only way to make it mortgageable again is to employ a professional company to remove the knotweed and offer a warranty for the work. We're happy to do this, but it seems to be coming in from our neighbour's land, since there is a hedge of it directly behind our back wall! Our neighbours want to cut it down themselves, and are refusing to allow a company access onto their land, even though we have offered to pay for it. And knotweed removal companies tell me that it would be difficult to get rid of just from our land, they'd need to do the neighbours as well. We've tried reasoning with the neighbours, but they remain adamant. Help! What can we do?
