The wood below a few of our large windows (windows are 96"x36") is rotting. It's soft to the touch, and a mouse or rat took a couple chunks out of it last night. I called a siding company, who referred me to a window company, and both kind of scratched their heads. A carpenter told me it was too big a job for him on account of the windows.
What kind of service professional would be able to help me with this? What would be involved in a repair like this?
