I have a reliabilt French door I purchased from Lowes and installed 2 years
ago. The side jams even though I primed and painted them before
installation, have rotted at the very bottom next to the sill. The
adjustable sill screws have seized and wont come out.
I looked online and called and it seems impossible to just find the top
adjustable part only. I really do not want to replace the entire threshold
as this door is only 2 years old.
Is there anything I could fabricate or otherwise to just replace the
adjustable top part? It looks similar to those adjustable oak thresholds but
is a tan plastic.
Any advice is greatly appreciated!
Is your sill similar to this one?
If so, I doubt you can buy just the part you want. Of course, if you can
find a sill identical to yours you could buy it and just swap out the
The jambs rotted because the sill butts to them; if the sill was under the
bottoms of the jambs, they would be unlikely to rot. If the sill was under
them and you left an 1/8" gap between them, they would not rot.
The adjusting screws rusted because water got into them, not from the bottom
but from the top. I have never seen any where water could get to them from
the bottom. When/if you wind up replacing them, pack the hole snd screws
with grease before you insert the finishing caps; they may still rust but
the grease should keep the rust at bay for a while.
