If your old wooden window is drafty, does not open or close well, or is
showing signs of water damage and decay, it is probably time to think
about replacing it with a state-of-the-art, Low-E glass, new vinyl clad
Also, if the glass pane associated with your existing old wooden window is
foggy or you can feel cold drafts during the winter months emanating out from
around it, or you need to hold it open during the summer months with a prop of
some sort then it is definitely time for a new window.
Replacing an old window is something a Do It Yourself homeowner can tackle
with some basic carpenters knowledge and a few basic carpentry tools that you
probably already have in your home.
Purchasing the Proper New Window
Prior to installing a new window you first need to figure out what size
window to purchase. The key parameter required when ordering a new window is its
rough opening. This is specified by the window manufacturer and tells you how
large of an opening you need for installing a specific window.
Typically the rough opening is 1 to 2 inches taller and wider than the actual
You may need to remove the interior trim from around the old window to obtain
the rough opening dimensions for your new window.
Make sure you purchase a new window that has rough opening requirements that
are equal to or smaller than your measurements.
Removal of the Old Window
Once you have purchased your new window it is time to remove the old one.
Using a hammer and a claw remove the old exterior trim and any nails that may be
securing the window to the home. There may be a nailing flange around the
perimeter of the old window. Simply use your hammer and claw to remove these
With the nails removed the window should be able to be pulled out of the
window frame opening.
Installation of the New Window
With the old window out, it is now time to install the new window. Before,
installing the new window, make sure the rough window opening is clear of any
debris and any old nails.
Place the new window into the window opening and center it within the window
Use a level and a measuring tape to make sure the window is plumb and square,
otherwise the window will not work properly. You may need to add some shims to
plumb and square up the new window.
Once the window is plumb and square within the window frame, fasten it with a
couple of nails. With most new windows they come with a nailing flange that
makes nailing the window to the outside home exterior straightforward.
When nailing the window, start on the upper right hand side and work your way
down with just a couple of nails. Check again with the level to make sure the
window is level and plumb. Also take one more look on the inside of the window
to make sure the window is secure.
If the window has remained square and plumb, go ahead and install a couple of
additional nails on the other side of the window. Again, one at the top, and the
other about halfway down the window.
Then go into the home and remove/cut away the retention bands that held the
window square during the window installation. Slide the windows up a down and
see if they operate smoothly.
If the window operates smoothly go ahead and add additional nails every 4-6
inches around the nailing flange of the window. If it does not, you may need to
remove one or more of the initial nails installed and readjust the window to
make sure it is plumb and square.
With the window now installed, add new trimboards around the window periphery
on both the inside and outside of the window and enjoy your new view.
