Wind, rain and open aspects
Houses on higher ground or facing open fields catch more wind-driven rain than those in sheltered streets. Rendered walls take on water, timber sills swell and window putty fails faster. Gutters that overflow in a heavy downpour send water down masonry, causing stains and flaking paint below.
It makes sense to clean gutters, fix leaks and repair render before any repainting begins. Bungalows with long, low elevations have a lot of wall to cover, and the bargeboards and fascias are easier to reach but still need proper preparation. In sunnier spots, south-facing timber can dry out, crack and fade, which needs sanding and re-coating with a flexible exterior finish.
