Hey Guys, if this is in the wrong section forgive me. We have a 70s sealed up fireplace and noticed we're getting moisture, mold and efflorescence around the hearth inside. Started with the main culprits.. cap, crown and flashing all OK. Pulled off the wood where an electric fireplace was installed and found a ton of insulation leading to the old Firebox soaked. Attaching some pictures, any advice on how to move forward would be greatly appreciated.
