Thank you. I guess I will call the installer back, or simply mix

It depends on what is under the threshold as to whether or not that
will work.

If it's just block like my garage entry was, then all you'll be able
to do is get concrete on the front lip and maybe along the ledge
where 2 block meet.

Other than that, the more concrete you push in, the more will just
fall into the block cavity.

The support really should have been added before the door was
installed, but I guess you know that by now.

I'd be interested to hear what the installer tells you.

One thing that the OP (Kate) may want to consider trying, if it is
possible in her situation, is the following:

Place a block of wood next to the metal threshold and tap on the wood
lightly with a hammer to see if you can cause the metal threshold to
slide out from under the door jamb/frame. If so, you will be able to
slide it out, see what is under it, and maybe add a filler piece or
some filler material while it is out, and then put it back.

I am not sure how the threshold is attached to the door jamb/frame,
but I had one that I did that to and it slid right out without any
problem. Of course, you would have to be careful when trying this to
make sure that no damage to the jamb/frame occurs while tapping on
the wood to move the threshold.- Hide quoted text -

I'm not doubting that you did what you say you did, but it sounds kind
of strange to have a threshold that is just sitting on the sub-
structure, un-attached to the structure or the door.

With both doors that I recently installed the metal threshold was
attached to the jamb on both sides.

I agree, it does seem strange. I didn't put that door in -- a contractor
did that one. And, they did some goofy things with this door (the trim was
on backwards), and with some interior door slabs that the did (they cut the
hollow door slabs to size, but didn't replace the filler piece so the doors
were open/hollow where they made the cuts on the top or bottom).

So, maybe when they did the basement entry door, they intentionally or
inadvertently took off the threshold from the frame during the installation
and then just slid it into place when done.

Of course, I stopped using those contractors and I ended up resolving the
other interior door problems on my own.

Doesn't sound like muxh of a contractor - and I'd bet they had
butchered the frame and threshold.
