Decay

These are often fixed by nailing them in place and then securing them with paint, so you will likely need to use an instrument to break them out of the way. Once the pockets have been removed, you can begin cutting out any wood rot and apply an extremely high-quality, water-resistant filler. Once the filler has dried it is recommended that a coat of primer be applied to guard against further decay.
