How to Install a Pre-hung
Window
Installing Windows
Introduction:
Most windows purchased today
are pre-hung windows. This means that they come
already assembled in a frame. This makes the DIY
homeowner job of installing a window much easier.
Other than getting the rough opening size correct
and placing the window level in the opening you
really can’t go wrong. If you don’t feel confident
about taking on this task on your own, consult a
DIY coach or a qualified window installer.
Here are some general instructions for how to
install a pre-hung window. These directions may
vary slightly from product to product depending on
the manufacturer. Always follow the manufacturer’s
recommendations when installing pre-hung windows.
Preparing the rough opening:
From inside your house, decide where you wish to
place your new window and mark the location. You
can do this by drilling a small hole through the
wall at each corner and then inserting long nails
through the holes so that they poke through to the
exterior of your house. Then use a level to draw
lines to mark the perimeter of the window opening.
From the outside, cut through the sheathing and
siding using the lines as a guide. Remove drywall
from inside. Insure that there is no electrical
wiring or plumbing lines in the area where you are
going o cut.
Note
If the wall is a load bearing wall you will have to
install a header above the opening. If the wall is
a gable end wall it is most likely not a load
bearing wall.
Place your window into the opening to verify that
it will fit. Remove additional material if
necessary.
Install water resistant barriers around the window.
Place the barrier around the edges of the
opening and tuck them inside and staple them in
place.
Mount the window in the opening from the outside.
Insure the window is centered and leveled.
If
necessary, insert shims along the sides, top and
bottom of the window to level it. Secure the window
to the opening by nailing the nailing strip to the
building. If there is no window nailing strip
secure the window by driving nails into the windows
exterior brick molding or casing.
Install exterior siding as may be required.
On the inside, stuff the area around the widow
frame with installation and install the interior
window trim to complete the window installation. That is how to install a pre-hung window. Related articles:
