While it may be tempting to simply plane a sticking door to fix the immediate nuisance, we strongly recommend that you first investigate the root cause, as persistent sticking is often one of the most reliable signs of foundation settlement. In Colorado, our expansive clay soils frequently swell and shrink, causing differential settlement that torques door frames out of square. If you plane the door without addressing a shifting foundation, the problem will likely return or worsen.

Before reaching for your tools, perform these simple checks to see if the issue is structural:

• Check for Binding at the Corners: Open and close the door slowly to feel for resistance at the top corner. Binding here suggests the frame is no longer square.
• Measure the Gaps: Use a tape measure to check the vertical gap between the door and the frame. A difference of 1/8 inch or more between the hinge and latch sides indicates the frame is out of plumb.
• Look for Accompanying Signs: Check for diagonal drywall cracks radiating from the corners of the door frame or stair-step cracks in brick veneer on your home’s exterior. The presence of multiple symptoms strongly suggests active soil movement.

If the sticking is persistent and does not resolve with seasonal weather changes, or if you find uneven gaps and exterior masonry cracks, you should consult a licensed structural engineer for a definitive diagnosis. As The Experts in Steel Piers, we can provide a professional evaluation and a custom quote for stabilization if structural repairs are required.
