I discovered carpenter ant damage to the framing underneath my double hung window. Ideally, I would like to replace the entire window sill plate and two of the supporting studs. How can I do this without removing the window, as the damaged studs and sill plate support the window? I could remove the window sashes and their counterweights to reduce the over all mass of the window. (Should have started on this during warmer weather.) Thanks in advance for any advice.
