I have a brick house that has wood trim at some points (At the
entryway, behind the house at a bathroom window and above the garage).
The boards (roughly 1x2s) are rotting; especially along the back side
of the house, and I don't think it's worth trying to repair them. The
rear window has a wood trim area roughly 6' wide and 7' high (excluding

The wood looks like:
except that nearly all boards have a certain amount of rot.
I gather that the proper procedure for replacing the wood trim is:
A) Decide on the type of wood I want to use to replace (size, etc).

D) Are screws or nails adequate for this type of job? It looks like the
original wood has some type of staple. I like screws myself but realize
they may look a little sloppy for exterior work, though I'll have to
