Hello, my wife and I recently bought a house which was built in 1969. We've since noticed that the floors slope down slightly from east to west - about 3-4 inches over the 29 foot width of the house, a consistent 0.5-0.7 degree slope.
Both floors (the concrete-floor basement, and the carpeted main floor) show this same slope.
We already demo'd the basement and the concrete foundation as well as the joists look good. All doors and windows work fine. There are no visible cracks in the walls or ceilings on either floor. We don't think there were any recent renovations or improvements to the place prior to our purchase.
I'll mention that since the demo (last weekend) the basement door has been a bit more difficult to open/close, whereas previously it opened/closed smoothly. Maybe we caused some movement in the demo - we removed a lot of OSB wall paneling although we haven't taken down any studs, and all windows still work fine.
Should we be concerned about the slope, or the movement since the demo?
