In our kitchen in the cupboards under the sink and against the back wall there is clearly a damp problem.
Also there is often a sewage/rotten egg smell around the same area and behind the dishwasher and washing machine. I have tried disconnecting both to see if there is a blockage or back-up but can't seem to solve the problem.
Ideally looking for someone to come round, take a look and suggest some possible solutions that they can work on.
