I have a 3 year old house that has a problem with expansion/contraction in
the winter. The house was built in the summer and consequently during the
winter I have a couple of doorways that go out of square and a few cracks
appear. Then when it warms up again that doorways go back to normal and the
cracks close up. (This is all on the inside).
I feel I should mention that the house is about ~80ft long with a ~35ft
steel I-beam supporting the back half of the roof. The beam was glued in
I am not sure if the beam contracting is the problem or not. Any ideas
about what is causing it, and how to fix it?
Don't think your problem is thermal expansion and
contraction. Doors moving around usually indicate
supports (foundation) moving around. If your
house is built on clay, the clay will expand and
contract with moisture content and the movement
will likely be uneven from end to end and from
side to side under your house.
That would be the first time I ever heard of a steel beam being glued
into place. It's very unclear what's really going on here. How out of
square do the doorways get? Where are the cracks appearing and how big
If I had to guess, I would think one of the problems might be the
difference in expansion rates of wood vs the steel beam? But if it
were me, I'd get a structural engineer in to take a look, especially
since it's a new house and under any new home warranty, a lot more is
covered earlier than later/
I am not sure if the beam contracting is the problem or not. Any
How big are the cracks, there is an amount considered normal and of no
concern, are they 1/32", or 1/4" I know an area of town built on an
underground river that all houses in the area have doors that dont close
in spring. Glued on beam, No. Just get a pro out.
The possible causes for this recurring problem are too complex to find
at a distance.
If it were my house, I'd be concerned about damage caused by the
You might find a forensic architect or engineer to examine the problem
and suggest a fix.
It's hard to say since there are a number of possibilities. In any
case, I would suspect that the problem is more a matter of humidity than
temperature. In addition I suspect that a good part of the problem is that
the house was built will wood that was too high a moisture content and have
