Soon I intend to install replacement windows. I find that the existing jambs are not looking that good and would like to replace them also. Since replacement windows are installed using the current jamb and after the old windows are removed I'm concerned about being able to install new jambs and if there are any suggestions about a hardware piece that I just learned about called a jamb jack. This item claims to be able to eliminate having to shim between the rough opening and the new jamb. Has anyone used them ? The concept seems okay but do they really do the job and make the jamb fitting task any easier ? I would prefer not o go all out and install new construction windows and feel that replacing the jambs may not be that much fun but is workable.
