Venting Exterior walls?

| So, the painting contractor we hired says that before painting the
exterior walls of our 100 year old home, we should go through and
install these 2" vents in the outside wall. One high, one low between
every other stud, to allow moisture to evaporate from inside the walls.
He says that moisture is actually pushing the paint off the house from
the inside. It makes sense but, in searching the Interweb, I have only
found two places that recommend doing this and dozens that don't say
one way or the other. Any suggestions? The house is in Washington
state. Lots of rain, very moist, not a lot of snow. Thanks for any
help-Warren

Is the paint peeling in large sheets? Are there blisters on the wall?
These are indications of excessive moisture. If that's the case, your
painter is correct.

| I had an old house with lap siding, the side that faced east could have used
the vents. Probably not the other sides.

Old houses are not as "tight" as new construction.
I live in an 1830s house in hot humid climate.
Painter - unbeknownsed to me - carefully sealed all the capboards.
Paint peeled off some parts of wall.
Sealant was removed from every third clapboard and seems to have solved
the problem.
