1. 2)While standing away from the house, also check the ridge line of the roof and the fascia line to look for any noticeable sagging, which is a sign of damage, settlement,  or poor construction. It helps to hold up any straight-edged object, like a notepad, when you sight along the building’s lines. The sagging ridge line in the photo below is likely due to removal of a horizontal structural cross-tie of some kind, such as a collar tie or ceiling joist with purlins, when the homemade dormer was added. 

  2. 3)As you walk around the exterior of the house, stop at each corner and look down the length of the wall with your face a few inches from the surface, searching for any areas that are bowing inward or outward.


  3. 4)Look for exterior wall cracks, especially ones that have opened more than 1/8”, cracks emanating from the corners of windows and doors, cracks that have one side higher than the other, and ones that show signs of having been repaired but have opened again. Take your time, and be sure to sweep your view up and down as you go along.

  4. 5)Look for signs of building components that are moving apart, such as where a chimney connects to an exterior wall, lines where perpendicular walls meet, or where exterior decks or landings connect to the house.

  5. 6)Test the windows and doors to make sure they open freely. Cracked window panes can be a sign of a buildup of structural stress or movement in a wall. Also, any missing interior doorways should be checked carefully. When the frame is so out-of-square that the door no longer functions, sometimes the door is removed as a quick-fix. The wood trim at the third photo below is buckling due to compression of the door frame.



  1. 7)Feel the floors under your feet as you walk, both for any sloping areas and soft spots. If possible, have any background music or television sound turned off during the walk-around. This makes it easier to hear any loose floor tile or creaking floor boards.

  2. 8)As you examine the interior and note any floor, wall or ceiling problems, try to correlate them with your exterior findings. How do they line up? Does a crack running across a concrete floor, for example, align with any structural distress you observed in the exterior walls? In the photo above, a badly out-of-square door frame was above a damaged pier under the home.

   Review your findings with a professional home inspector or engineer if you think you see signs of a big problem lurking in the structure. The significance of wall cracks in particular, unless they are gaping and ominous, is best left for a professional to interpret. A few minor settlement cracks should be expected, especially in an older home, and a pro can sort out the actual problems from the cosmetic defects for you.
