Common Symptoms
Glass door that will not pull fully closed, leaving a visible gap along one edge of the frame
Door that closes but will not latch — the latch bolt does not reach the strike plate or falls short of the hole
A noticeable draft or visible daylight around the door perimeter even when it appears shut
The door requires lifting or pushing upward while closing to engage the latch, indicating the door has dropped on its hinges
Binding or scraping along the top or bottom edge of the door frame when opening or closing
What Causes This
Hinge settling in wood door frames — wood compresses and expands with humidity cycles over time, causing hinges to loosen and the door to drop and shift
Foundation or structural movement creating a parallelogram-shaped opening where a rectangular door no longer fits correctly
Frame warping from prolonged moisture exposure — wood frames in humid DMV summers or near exterior water sources can bow or twist significantly
Worn or broken pivot hardware on frameless glass doors — the upper and lower pivots that carry the full weight of heavy frameless glass doors wear down over years of use
Failed door closer or overhead hydraulic mechanism that no longer provides controlled closure, causing the door to stop short before the latch engages
How to Fix It
Solution Steps
1Identify where the door is failing — observe carefully whether it binds at the top, bottom, latch side, or hinge side to localize the root of the problem
2For a door that has dropped, check hinge screws first — loose screws allow the door to sag, and re-tightening or replacing with longer screws often resolves the problem immediately
3For a latch that does not reach the strike plate, use a pencil to mark the latch bolt position against the strike plate location — adjust the strike plate mortise up or down as indicated by the mark
4For frameless glass doors with pivot hardware issues, do not attempt to shim or force the door — the pivots carry hundreds of pounds and improper adjustment can cause sudden catastrophic failure

When to Call a Professional
For any frameless all-glass door — the hardware systems on frameless glass doors require specialized tools and expertise to adjust safely
When the door frame is visibly out of square and the problem is structural rather than hardware-based, which may indicate a building issue that needs to be addressed first
When the glass panel itself has shifted in the frame or is making contact with the frame, risking a glass stress fracture
When the door is an exterior entry door and a security gap exists because the door cannot fully close or latch
Stay Ahead
Prevention Tips
Tighten hinge screws on wood-framed glass doors annually — loose hinge screws are the most common cause of door drop and alignment problems
Keep door frames painted or sealed to prevent moisture absorption and wood swelling that distorts the opening geometry over time
Lubricate pivot hardware on frameless glass doors every year with a silicone-based lubricant to reduce wear on the bearing surfaces
Do not allow glass doors to slam — install a door closer or floor stop to control swing speed and protect both the glass and the frame hardware from impact fatigue
Common Questions
FAQs About This Problem
This is classic wood frame hygroscopic movement. Wood absorbs moisture from humid summer air and expands, tightening the door opening. In dry winter air the wood contracts and the door swings freely again. The long-term solution is sealing or painting the frame surfaces to reduce moisture cycling and adjusting the hinges to accommodate seasonal movement.
