Anything outside of your home will need a certain degree of upkeep. Generally, siding requires little. Vinyl siding will need power washing to remove that layer of dirt that’s likely built up over time, and fiber cement siding might need fresh paint after 15 years or so. Don’t discount this: It is critical that the gutters work properly so running or splashing water from rain or snow melting off the roof does not have unrestrained access to batter your siding.
