I've got some rotten window sills that need to be replaced - not repaired, done that, it never works successfully. They're wooden casement windows about 25 years old on friction hinges so can be easily removed. How far does the sill extend under the window frame; is it attached to the inside sill; How is this sill fixed; how do you get it out, and how do you attach the new sill to the old window frame?
