REMOVING YOUR OLD SLIDING GLASS DOOR
Last week I explained how to measure your existing sliding
glass door so you can order the vinyl replacement door. This
week I am going to go over the steps required to remove the old
sliding door before installing the new door.
First, you have to remove the sliding panel and the stationary
panel. The vast majority of doors out there have the sliding
panel on the inside half of the track, and the stationary panel
is on the outside. Whatever the case in your particular door,
the outside panel has to come out first. To remove the fixed
panel, you need to remove the sill cap that snaps into the
bottom track and runs from the fixed panel to the side jamb
where the sliding panel locks. Force a screwdriver into the
crease and pry the cap up. Then, look for screws on the inside
side jamb holding the fixed panel in place. These screws prevent
someone from prying up the sill cap and pulling out the fixed
panel in order to gain entry into the home. In addition to the
side jamb, be sure to check across the top header and bottom
track for screws there as well. Once all the screws have been
removed, you need to pull the fixed panel away from the side
jamb. You can start by simply grabbing the side rail of the
fixed panel and pulling as hard as you can. If you're lucky, the
panel will pop free. Then you can lift the panel up as far as it
will go into the top channel and swing the bottom away from the
track, and remove the panel. Now, I said "if you're lucky",
because in most cases the panel will be stuck in the side jamb,
the bottom track, or both. Usually, you're going to have to use
a pry bar to loosen the fixed panel before it will slide out of
the side jamb. Once the fixed panel is out, removal of the
sliding panel is usually easier. Just lift up and swing the
bottom away from the track, then remove the panel. Sometimes the
bottom rollers will prevent the bottom from swinging out of the
track. If that's the case, you will need to find the roller
adjustment hole in the bottom corners of the sliding panel. Put
a screwdriver into this hole and turn the screw counterclockwise
to bring the roller as far up into the bottom of the sliding
panel as possible. This should allow the slider to come out.
Now, you want to remove all the screws from the side jambs, top
header, and bottom track. Then, take a pry bar and get it under
the bottom track about in the center. Pry up until the track is
separated from the floor. The next step will depend on whether
your old frame is nailed to the house frame, or simply screwed
in. If it's screwed in, then the frame should now be loose in
the opening, since you removed all of the screws. You just need
to remove whatever inside trim there might be around the door
frame. This type of frame should come out. If your door is
nailed to the house frame, you will have to do a bit more work.
Use a hacksaw to cut the track in half, approximately in the
center. Start with either half and raise the cut piece up
towards the side jamb until the the track piece separates from
the side jamb. Do the same thing to the other half.
So, now you have to remove the side jambs. You want to do this
without damaging the exterior material that surrounds the door
frame. Take a heavy chisel and pound it into the crack between
the frame and exterior material, whether it's stucco, siding,
etc. Start at the bottom 6 inches first. What you are trying to
do is pull the nail fin away from the nails holding it in place.
So, once the chisel is pounded through the metal frame, pry away
from the side wall. The heavier and longer the chisel, the more
leverage you will have. You will hear the frame "pop" free of
the nail. There will be several nails holding each jamb in
place, so you want to start at the bottom and work your way to
the top corner. Once you get the bottom third loose, many times
you can grab the jamb with both hands and pull the rest of the
nails free as you go up. When you get to the top corner, work
the jamb free. Do both jambs, then do the top. Sometimes the top
has no nails, or just one in the center, so it will come down
pretty easily. Be sure to wear safety glasses and a dust mask
when doing this job, especially when removing the top header.
At this point you are ready to install the new door. The
installation procedure is slightly different, depending on
whether you're installing a retrofit style frame or a
replacement frame. We will discuss both procedures next week.
