I have this inspection scheduled Sept.12 for a 1988 colonial. I was there this morning doing a water test and as the house is unoccupied I thought I would look around and get a head start. There is also an addition a 3- car garage with an apartment over it that was build in 1997. The garage floor has a moderate amount{too much in my opinion} of cracks in the slab and slopes more than it should toward the doors.{cracks have caused this}Went out to my car and checked different areas with my level nothing unusual,except sloping and cracks in slab. When I went in the house I found that none of the interior doors will close{They all hit door jam} upstairs a couple of doors don't close properly but nowhere near as bad as downstairs. I put a level on the door frames and they were not perfect but no worse than most I have come across including my own. Doors to the front exterior works fine as well as siding glass doors{did not check windows yet}door leading do the garage closes a little hard but not as bad as interior doors. No excessive cracks in walls and basement foundation looks find,just a couple of very small hairline cracks.I have come across a couple of doors out of wack in the past and once a house similar to this with interior doors out of alignment but that house had major foundation issues. Any ideas of what i should be looking for Monday. I would like to give my clients some idea of whats going on. Thanks for any advice, John Callan
