Hanging a door is considered by some to be a true measure of carpentry talent or skill. A door only 'works' when fine tolerances and clearances are set up, levels and plumbs are true and seals are tight and sound. Well if you aren't a carpenter, your ability to hang a door may be only average, by these standards.
However there are now 'pre-hung doors' which you can specify in your inclusions, which make hanging a door effortless. These interior and exterior doors arrive with a fully assembled frame, with the door hanging on the hinges, ready to plumb and install. The assembly will have timber braces to keep it square as you install it, and the kit home prefab frames will be itching for a that perfect door. What could be simpler.
