On most coastal properties one elevation does almost all the work. The south-west face takes the driving rain, the salt-laden gusts and the bulk of direct sun, while the opposite side of the same house can look barely touched years later.
Yes, and it is usually the sensible approach. There is no requirement to redecorate every elevation on the same date, provided the specification and colour match when each side is done.
If a probe sinks into the timber or the joint has opened enough to let water track inside, replacement of that section is normally more reliable than filling and repainting over it.
Often a higher-build, more flexible exterior system on the weather side outlasts a standard finish, even where the sheltered elevation is perfectly well served by the standard product.
It is common to find a north-east elevation still holding its original finish while the south-west face has failing putty lines and lifting paint at the sill. Treating both sides on the same repaint cycle either wastes a visit on the sheltered side or leaves the exposed side to fail unattended.
Wind-driven rain finds horizontal surfaces first: sills, bottom rails and glazing bars that sit proud of the frame. These are the details worth inspecting closely before assuming a whole window needs full removal, since a localised repair can sometimes be enough if caught early.
A flexible, breathable exterior system with a slightly shorter recoat interval on the exposed side, paired with a more standard cycle elsewhere, usually costs less over time than repainting the whole house to the same schedule.
Send photographs of your south-west facing windows and we will say whether repair or replacement of sections is needed before repainting.
One elevation usually carries almost all the weathering on a coastal house, so it deserves its own inspection and its own interval.
