Every once in a while, you may find yourself with
a torn window screen, usually due to child mischief. Replacing
a metal-frame window screen shouldn't be an arduous task.
Caution: Of course, when dealing with sharp
objects, such as a carpenter's knife, make sure you take precaution.
Replacing a metal-frame window screen can be done in a few steps,
and here's how:
Lay the screen on
a flat work surface.
With either a
sharp object, like a nail, or the preferred tool of an awl, pick
at the existing vinyl spline so as to remove it from the metal
With the spline
removed, carefully pull off the existing screening.
Unravel enough of
the roll of screening so as to cover the metal frame, allowing
at least an inch and a half of such screening to overlap around
all the edges of the frame when it is correctly aligned over the
metal frame and is about to be cut to such a size.
With a carpenter's knife, cut the new screening to size as laid out
on the metal frame, making sure, again, that at least an inch and a
half overlaps around all the edges of the frame.
Using a screen
spline roller's convex-wheel side, roll this newly cut screening
into all the channels of the metal frame, all the while
maintaining a fair amount of tension on the other side of the
screening in the process so that ultimately the screening,
overall, is rolled into place, in the correct alignment as the
screening was laid out in step 3. (It is important to not
over-tighten the screening when rolling it into the channels of
the metal frame because this may cause the frame to slightly
bend out of shape and not conform to the original shape as
before in order to effectively keep out insects.)
Important note: If you use fiberglass screening, such screening must
be rolled into the channels of the metal frame along with the
vinyl spline at the same, so steps 5 and 6 are effectively combined
into one action with such a fiberglass product.
into place the screening all around the interior channel edges
of the metal frame, secure this rolled-in screening with the
rolling of the vinyl spline, using the screen spline roller's
concave-wheel side. Use a screwdriver to help insert this spline
as needed, in addition to the roller, especially at the corners
of the metal frame.
Once you are done
with the insertion of the spline, you are now ready for the
final task: Using a carpenter's knife--aimed to cut outward from
the frame edges--cut the the excess screening that overlaps the
edges of the metal frame. Once done with the cutting, reinstall
the metal-frame window screen on your window as it was
That's what it takes to replace a metal-frame
