Greetings, and thanks for reading.
We had a problem with the entry door in our older home. The deadbolt was
not lining up, and by looking at the jam, it appeared that this was a
problem thru the years. We decided to replace the door about 2 years ago.
It was installed correctly, and was nice and level at that time.
This is where the problem starts. 6 months ago, the deadbolt was higher
that the hole, and the top of the door was scraping when it was closed, to
the point that it was scraping the stain off the jam. My brother-in-law
helped me put some shims under the jam side of the opening, raising up that
side so everything seemed square again.
About 3 weeks ago, the dead-bolt was too low to go into the receptacle.
Brother in law came over again, and we took out the shims, which didn't make
much difference, and put some cardboard behind the lower hinges. All was OK
at that time. Week later, deadbolt didn't work again. Called a contractor
to come over to take a look, and he put about 3 shims under the sill on the
hing side. Worked close to fine, just a bit of a drag on deadbolt. 3 days
later, barely can get deadbolt to work when I lift VERY hard on door knob.
I know something is going on making the hinge side of the door sink. I
cannot get to the foundation on the outside of the house because of a cement
porch, and on the inside a floor joist is within 6 inches of the foundation,
making it next to impossible to do anything but "feel" the problem area.
Jacking up on the floor joist does nothing to the situation. I have a
feeling that my problem may be with the wood beam that sits on the
foundation. It may be rotting, but where do I go from here?? My concern is
with the in-accessibility of the sill.
Guesses or suggestions???
