Hi, we recently moved into a house. It seems to be concrete slab foundation, because I cannot find a crawlspace entrance. There is a bedroom adjacent to a bathroom and a pipe (not sure what the pipe is for, but it's in a storage room adjacent to the same bathroom. We found that there was significant dampness in the gyprock boards between the store room and bedroom, so we removed it. We then found really bad wet wood rot in the wooden frame (see pictures). I'm not sure whether it's due to a hidden leak in the pipe, or leaks in the bathroom. Although the shower was leaking a bit in the bathroom and some wall tiles had cracks.
Just wondering, how would I get rid of the dampness and wood rot? My plan currently consists of the following:
1. Fixing the leaking shower head
2. Removing the bottom bathroom tiles around the shower and reapplying waterproofing membrane.
3. Hopefully the pipe isn't leaking, so that should resolve the issue. Then I'll remove the wet rot from the wood frames, apply wood hardener and wood filler.
Is this the right approach? Should I consult a plumber prior to all this? Thanks.
