The exterior wood window sill on one window has rotted away over the years.
I have aluminum single-hung, single-pane windows and a masonite-like siding.
Is there a way to replace the 2"x6" sill and not have to remove the entire
window? All of the windows and siding will eventually be replaced but I need
to get a few more years out of them.
Thanks in advance.
I've replaced a few with pressure treated wood. If your's are like mine,
they are not really a structural part, that is they are not an integral part
of holding up the window. Not much nailing required and I sealed them with
caulk and painted.
If it's not totally gone, you could probably reconstruct/repair the
existing one as an alternative as well and get several years more to
get you to the full replacement time. I've used the "PC Woody" two-
part as well as the one part stabilizer successfully on the barn
restoration. If you buy the larger sizes rather than the tiny little
ones, it's not excessively expensive. An inexpensive alternative if
need to reconstruct an area is regular old Bondo, too.
Again, as another responder said, it's quite possible if you
investigate you'll be able to remove the sill relatively simply and if
so, that's probably best. But, if you're only looking for short-term
repair with major restoration on down the road anyway, the alternative
is worth consideration any way.
I can't give you a brand name because I don't know it. The easiest one of
the two that I have used comes in 2 pieces with all angles precut. The
exterior lip that is normally such a pain to cut out is a separate piece.
You cut the "interior piece" to the width of the window frame, slide it into
place and secure it. Then the exterior portion is glued and nailed into
place. The whole thing is ramp cut to provide the proper slope to match the
I also used another brand one time that was a duplicate of the old wood
sills. It is a bit harder to fit but also works well. Around here one
brand is sold at a mill shop and the other is sold at a brick yard that also
sells millwork. So I guess the best place to look for either is at a
millwork shop in your area.
