The following illustrates the general principles in-
volved in the installation of a pre-hung exterior door
unit. Installation instructions may vary slightly among
manufacturers. Always refer to the manufacturer's
instructions as the authority for the door assembly
you choose to install.
Preparing the Rough Opening
Step 1: Remove the
new door assembly from
the packaging. Some
doors are secured for
shipping by screws in-
stalled through the
jambs into the doors. For
these units, the screws
should be removed at
this point. Other units
have shipping braces
that shouldn't be re-
moved until the door is
shimmed into the open-
ing.Step 2: Remove the
existing door and frame down to the rough opening
Step 3: Assure that the rough opening is plumb and
that the subsill (the floor under which the door sill will
rest) is level. Level the subsill if necessary by using a
beveled board or shims. A spacer board may be nec-
essary if the door must clear an unusually high floor
surface, such as very thick carpet.
Step 4: The rough opening should be at least 1 inch
wider and taller than the outside frame dimensions of
the door system to be installed.
Step 5: Apply two generous beads of caulk along
the subsill an inch inside the front and rear edges of
where the sill will be placed. Extend the caulk a couple
of inches up the sides of the rough framing.
Placing the Door
Step 1: Place the door
into the opening. Put in
the bottom first with the
top facing outward to-
ward you, then tilt the
door into place.
Step 2: Centre the
door in the opening and
shim the frame tightly in
place at the very bottom
of the rough opening.
Squaring and Securing the Assembly
Step 1: Now that the
door is roughly in place,
shim the rest of the
door frame as neces-
sary to hold it in place.
During this step, place
shims on the hinge side
of the door behind any
points in the door
frame. The door will be
to the rough opening at
these points later.
Step 2: Adjust the shims and frame assembly
until the jamb on the hinge side of the door is
plumb in both directions. There should be a con-
stant gap (about 1/8 of an inch) between the
jamb and the edge of the door.
Step 3: After making these adjustments, tem-
porarily nail the door in place with 16d finishing
nails through the hinge jamb near the hinge loca-
tions. Don't drive the nails all the way in.
Step 4: Remove any shipping braces from the door, then
open and close it to test its operation. It should operate freely.
Step 5: From outside the house with the door closed, make
sure there's an even contact between the door face and the
weather stripping attached to the frame opposite the hinge
jamb. Make any adjustments if necessary by adjusting the
jamb in or out at the top or bottom.
Step 6: From inside the house with the door closed, examine
the edges of the door. Adjust the lock-side jamb until there's
an even gap (about 1/8 of an inch) all around between the
door edges and the faces of the jambs.
Step 7: Install a solid shim behind the lock strike location.
Step 8: Permanently secure the jambs. Begin with 3-inch
screws driven through the shims at the hinge locations on the
hinge jamb. Continue around the door, securing the remaining
jambs with screws or nails (as recommended by the manufac-
turer) driven through shims. Install the screws or nails through
the shims to prevent distorting the door frame by putting
pressure against an unsupported area. Check the door occa-
sionally as you perform this step to assure that the door as-
sembly remains properly adjusted. Install screws through the
shim at the lock strike location.
Finishing the Job
Step 1: Insulate around the edges of the door frame with
loosely packed fiberglass insulation or low-expansion foam.
Foam that expands too much could distort the door frame in-
ward, impeding the operation of the door.
Step 2: Install the interior trim per the manufacturer's in-
structions. Caulk all joints and intersections of the trim and
brick mold, particularly along the joints where the brick mold
meets the exterior wall, with paintable caulk.
Step3: Install the weather strip at the base of the door as in-
structed by the door manufacturer (if necessary).
