I have a section of wood siding that is soft and rotting. Complicating matters (and possibly causing the issue) is the placement of the seating area of the deck. The previous owners built a privacy wall and bench and it abuts the house.
The wood that I've tapped around the area feels firm, the damage is primarily on the top section of one plank.
Any advice on the steps, tools, and materials I'd need to properly repair this are appreciated. I'm concerned some moisture is in the wall cavity; after a recent heavy rain I noticed some minor paint bubbling on the interior side of this wall.
