I have recently purchased a Hunter passage 450 and have noticed that the galley floor is quite spongy. I believe that the timber floor has become rotten, possibly due to moisture from the fridge. Has anyone replaced the galley floor and what is the best way to approach this? I believe once the floor is removed I may be able to find the source of the moisture and find a way to solve this issue. Any help or advise would be much appreciated.
