I live in the hot and humid Southeast US, but our house has some stucco on the front. Poor sealing have led to two major repairs (by previous owners) on this house that we know of, so I'm pretty paranoid.
I have house numbers and want to attach them to the house. They screw in. Normally this would be easy, but I'm really really nervous about drilling into the stucco. Am I right to be nervous? Or will the screw keep out any moisture?
