Most of the windows in my house seem to move when the temperature changes.
On colder days I can see about 1/16 inch gap around the outside calking. As
soon as the temperature warms up the gap closes up. I have recalked with a
good quality calking twice now, but the problem persists. Someone suggested
that perhaps the windows were installed incorrectly. There are no visible
signs of movement or cracks in the foundation or around door/window jams or
what kind of good quality caulk did you use? in a situation like that
you would want an extremely flexible oil based caulk, either
polyurethane or one part urethane or something similar. it shouldn't
be water clean up, nor should you use silicon. these can be tough to
find in the big box stores. I have used vulkem, chem-caulk, np-1, to
name a few brands. there are others.
My buddy is a conrtactor and got the calking for me. I am not sure what he
brought over, but he did say he got a good quality calking. I will ask him.
But I am really trying to learn what would cause the windows to move so much
with no obvious movement anywhere in the house.
what kind of siding is on the house? do you know that the window is
moving, or is the trim/siding shrinking in the cold? do the sashes
operate? do they leak cold air or water? from what you've said, your
problem sounds like it due to thermal contraction/expansion. hard to
see how that could relate to an installation.
again, you could be using the best caulk money could buy, but it needs
to be the right type. i guarantee you there are caulks out there that
can handle this type of movement.
Yeah, cause "the outside caulking" is a clear, precise, and
accurate description of where the problem occurs. There is,
after all, only one seam that could possibly be described
as "outside". Be sure that you don't tell us if the windows
are original or replacement, for certain don't mention if
they're vinyl, wood, or metal. A picture posted somewhere
would be totally over the top. Anyone who can't just pull
all the relevent information out the ether is clearly
unqualified to give competent advice anyway. Oh, and it's
dangerous to tell anyone where the house is, on account of
you might attract stalkers.
Consider the following procedure:
1. Question asked.
2. Information presented sufficient: Answerer answers question. END
Information presented insufficient: Answerer asks for clarifying information.
3. Questioner gives clarifying information.
4. Clarifying information sufficient: Answerer answers question. END
Clarifying information insufficient: Answerer asks more precise questions.
And, this accompanying hint: not everyone in earshot (or Usenet-shot) has to
consider themselves an answerer.
In other words, if the above procedure overwhelms your meagar patience, you can
take the option to STFU.
