When doors and windows go crooked, the wall moved first.

Doors and Windows Misaligned: diagnosed and explained.

Misaligned doors and windows mean the walls holding them have shifted, and walls shift when the foundation settles unevenly. The evidence shows up as a collection of small annoyances that share that one cause. A window sash that jams halfway. A door that scrapes its frame at the top corner. A visible tilt in a door reveal, tight on one side and gaping on the other. Trim that has pulled away from the wall at a corner. Each opening in a wall is a rectangle framed into the structure, and the openings hold their shape only as long as the structure holds its shape. When the foundation settles unevenly, or soil pressure shifts a wall, the framing racks and every rectangle in it leans a few degrees toward becoming a parallelogram. Windows show it fast because sashes ride in tracks with tight tolerances. In Southern California, Arizona, and Nevada, the usual force behind the movement is expansive clay, swelling with winter moisture and shrinking through the dry season, so the foundation never gets to sit still. Seismic activity and hillside soil creep add their own push in parts of our service area. The pattern to watch is clustering and progression: several openings distorting in the same region of the house, getting slowly worse, usually alongside drywall cracks and floors that lean the same way. That combination separates a structural cause from simple frame wear.
