How long is the sill?
How bad is the rot?
Does the rot extend into the stud cavity?
How many bends in the capping?
Are you a nice person?
I could go on for pages with questions, your best best is to have a skilled installer/window rep take a look at your sills and capping needs. Generally within a minute (without rot issues) they will have a price in their head.
We usually replace a sill nose at no charge. Full sill, depends on situation, probably $100-$200. Capping $65 per standard size opening unless it is some kind of crazy exotic bend or uses up a ton of coil.
