With installing a window and its frame comes
installing the complementary window trim. Window trim helps define
the window and give it a finishing look. While there are
various types of window trim that you may choose from, to avoid
having to devote time to sketching and planning out complicated
designs, what is focused on here is simple mitered casing/trim,
which is fairly popular.
Caution: When dealing with sharp objects, such as a
saw, make sure you take precautions;
read all product manufacturer instructions.
Installing window trim can be done in a few steps,
and here's how:
Ensure that the
window frame sides are level, first
and foremost, using a small carpenter's level; if not, add or
otherwise adjust the shims between the sides and the structural
opening of the house to which the frame is attached.
Ensure that the
left and right window frame sides are each square to the head
window frame side, using a carpenter's framing square by placing
it against such sides, side by side (i.e., left to head sides
and then right to head sides), to accomplish such a task; if
not, add or otherwise adjust the shims between the window sides and the
structural opening of the window to which the frame is attached.
With a tape
measure, measure the length of the left, right and top window
frame sides, and write these respective measurements down with a
pencil on a sheet of paper. Having the side trim placed
against the one of the window frame sides, determine the extent
of what the reveal will be; mark the reveal of each window frame
side in two spots along its length.
Cut the side
trims to the determined written-down measurements of the left,
right and top window frame sides, and, at the same time, in
consideration of the reveal points, also make the
necessary 45-degree cuts of the top ends of the left and right
trim sides and at both ends of the top side trim with the use of
a wooden miter saw box and handsaw--all so that these side trims
will ultimately join, when finished, in conformity as perfect
corners at the very top of the trim scheme. (For cutting
angle cuts of the trim for more than one window, you might
consider buying a power miter saw, as with practice, it
efficiently enables one to make professional cuts in no time.)
As may be needed,
use coarse sandpaper to sand away any rough, uneven parts of the
trim sides just previously cut to size.
Now, with the use
of a hammer and trim finish nails, go ahead and tack the trim
sides together around the window frame, starting with the left
and right trim sides and then the top trim side, so that, as
previously noted, these side trims join in conformity to make
perfect corners at the very top of the trim scheme. (The
trim sides should be flush against the window frame sides.)
The trim finish nails should be hammered in below the surface of
every trim side about every six inches apart.
With a caulking
gun, cocked with a caulking tube of white caulking, fill in the
crevices/gaps found between the trim sides and the walls, and
use some drywall compound with a joint knife to cover up the
nails and nail impressions so as to become flush with the
surface of the trim sides.
That's how to install
window trim. When you're ready, you can paint the trim and the
