When interior doors suddenly begin sticking at the top corner, it is often a sign that the home’s foundation is shifting. In the Denver metro area, our expansive clay soils are a primary culprit; these soils swell when wet and shrink during dry periods, causing differential settlement that torques door frames out of square.

While minor, temporary sticking can be caused by seasonal humidity, binding at the top corner is a classic indicator of structural movement. We recommend checking for the following accompanying signs:

• Diagonal Drywall Cracks: Look for cracks radiating from the top corners of the door frame, as these frequently signal foundation settlement.
• Uneven Clearances: Use a tape measure to check the gap at the top of the door frame. A difference of 1/8 inch or more between the hinge side and the latch side suggests the frame is no longer plumb.
• Exterior Indicators: Inspect your home’s exterior for stair-step cracks in brick veneer, which follow the zigzag pattern of mortar joints.

If the sticking persists beyond seasonal weather changes or is accompanied by these other red flags, it warrants a professional evaluation. As a family-owned and operated business since 1996, we specialize in identifying these structural issues and providing permanent stabilization through helical piers and other engineered solutions.
