Some of you may recall my question about repairing this crumbling
You'll note that there is an entry door to the right of the crumbling
I ended up replacing both the door (old wooden door with a rotting
threshold) and the block.
In both the original installation and the new, there is a gap between
the end of the block and the bottom foot or so of the door jam. If you
look at the picture, that thin strip of material directly under the
jack stud is a strip of mortar between the block and the old door jam.
There was a duplicate strip of mortar on the other side of the door
which came out when the old door was removed. I now have to fill these
gaps to finish sealing the door.
The left side gap is a little bit less than an inch wide and the right
side is just under 2 inches. On the exterior side, there is a piece of
aluminum flashing that is nailed to the brickmold with a flange that
used to hide the original mortar strip. In other words, if you look
through the gap between the block and the door jamb from the inside,
you can see the "back" of the flange that used to be up against the
My question: Should I mix up some mortar and use a mortar bag to
squeeze mortar into the gaps or should I take the easy way out and
just use minimal expanding foam? Eventually I plan to parge the block
inside and out and I'm wondering if I can parge the foam on the
interior also or will it always be visible?
Thanks for any advice.
