How often should you pressure-wash your siding?

Grumpty's answer
Every 12 months
Why bother
Grime and algae age the siding early. A thorough-tier job. Skippable when life's busy, worth it when it isn't.
When to start thinking about it
Give yourself about 14 days' notice. That's when Grumpty starts grumbling, so it doesn't land on you the day it's due. Mark it done and Grumpty sets the next one, every 12 months, so you can go back to forgetting it exists.
Let Grumpty remember it for you
Add it once. Grumpty tracks the date, grumbles when it's due, and rolls it forward the moment you mark it done. No spreadsheets, no sticky notes, no forgetting.
