So, I had some water damage in my trunk and for the longest time thought it was the wing on my trunk leaking. Turns out I had 1" of water in the wheel well. Finally decided to fix the problem. This is being done on my 2004 Subaru WRX.
Things to do before: Make sure you locate the source of the water. In my case it was water under the carpet. However your issue maybe bigger than this.
-Heater (to ensure all cracks are dried)

- 4' x 6' Carpet - $12

Step 1: CLEAN
Once the leak/ problem is solved its time to clean. Mine had 1" of water in the wheel well and I don't know how it got there. I also had the smell of mildew throughout the entire trunk.
Step 2: Cut Out the Board
The board the car came with is like a compressed cardboard sheet. So I decided to upgrade since it was thoroughly soaked and smelled of mildew.
Step 3: Make the Carpet
Simple process same as the last step, just trace and cut out.
Step 4: Assemble
This is the final product. Although only $24, it in my opinion looks very professional. It sure beats the retail price of a new trunk liner.
