I would like your advice on whether I need to repaint the timber exterior of my 2nd floor balcony. The house was built in 2008, so the paint job is about 12 years old. In this part of the world, it can get to around 0 degrees (32 F) in winter, at night. It can get to around 40 degrees (104 F) in summer, during the day. It does not snow, but it can rain against this side of the house. It is South facing (in the Southern hemisphere), which means it only gets direct sunlight for ~2 months of the year, during summer. However, this is when the sun, UV, and heat are at their highest.
The paint is pealing in places and it looks like there are some gaps developing in the timber. In this last photo, it looks like a splint about an inch long has developed on this side of the frame.
