How To Remove and Install A Pre-hung Door #DIY #Homeimprovement


– [Narrator] We want to
install this pre-hung door, or our most cost and time-efficient way to perfectly replace a door. So, let’s begin. Score the casing, or trim
covering the door jambs, and remove it. Also, remove the door from
the hinges using a drill. To remove the existing
door jamb, cut it in half using a reciprocating saw, or sawzall. Remove any screws holding
the jamb into place. Often, they will be found near
the hinges and strike plate. Clean the threshold of any debris as we prepare for the installation. And remove any hardware
or cardboard on the frame of the pre-hung door
you’re about to install. We can start by checking
for level and plumb on the hinge side of the door. By seeing how out of level
a jamb is, we will know how much we will need to
adjust the frame using shims. We have a problem. Our door and frame are 1/4 inch too tall, and our door is hitting the floor. If we take 1/4 inch off
the bottom of the frame, we can then raise the frame higher, and the door will clear the floor. So we measure 1/4 inch
back from the bottom, mark it with a speed square,
and using a multi-purpose tool, or a skilsaw, cut those lines. You can also use a
multi-purpose tool to ensure there’s no impediments to the door frame. We now adjust our low hanging door by shimming our door jambs up by 1/4 inch. Do not over think this. Remember, when hanging a pre-hung door, always start by leveling and
plumbing the hinge side first, and go from there. So, after plumbing our
door all the way around, we continue to check for level. Using a four or six-foot
level as a straight edge, look down the straight edge, and notice the gap between
the jamb and the level. We shim that slightly to move
the jamb, closing that gap until the level and jamb
are completely flush. We keep shimming below the hinges, and wherever is needed
to square that jamb. And, after shooting with
an angled finish nailer or brad nailer, cut the shims. Now that we have the hinge
side leveled and plumbed, we simply make the reveal
consistent all the way around. Recheck for level on hinge side, and let’s begin on the strike
side, or doorknob side. Work your way down the jamb, simply making your reveal consistent, and double checking your
work with the level. It is important to shim above
and below the strike plate for added strength. You can use a wood block to make slight adjustments of
the jamb or door stop. And make sure your door now closes flush with the door stop of the jamb. Now, we shim our header. Our door should now swing freely,
1/4 inch above the ground. And now for our casing, or door trim. You choose what reveal, or how far your trim sits back from the jamb. We are going with a 3/16 inch reveal. Measure that. And these are our short
points of that angled cut. A mitered joint is a cut
at a 45-degree angle. Measure from short point to
short point and make that cut. And install your header piece first, keeping our reveal consistent and perfect. Now you can measure from the floor to the long point of the header piece, or simply mark your casing piece, and cut. And don’t forget your
doorknob, and strike plate. And we’re done. A new, pre-hung door for our
home, ready to be painted. For more videos in this series,
