Painting or staining a house every 6 years falls with-in the normal range for re-coating.

Most re-staining and re-painting needs to occur every 3-7 years on any wood sided home.

No need to remove and replace the siding because you will still need to restain the house in about 6 years even with new cedar.

If you want to avoid restaining, you will have to install another exterior wall covering that wouldn’t need painting like vinyl, stucco, stone, etc…
