Hello,
Any way to add/replace new wires without destroying drywalls ?

Thanks
Aleksey


Vertically in the same area ( between the studs), not much of a problem
depending on the age of the construction. Newer homes may have fire blocking
at 4 or 8 feet.

Side to side past a stud, your going to need access from above or below to
accomplish this one.
