Sticking doors are a common household issue that can cause inconvenience and even frustration. Whether your front door is sticking at the bottom, an internal door is catching on the frame, or a swollen wooden door refuses to close, these problems often have simple explanations and solutions. In some cases, however, they may point to underlying structural issues. Here’s a practical guide on how to fix sticking doors, along with advice on when to seek professional help.
Why Do Doors Stick?
Doors can stick for several reasons, ranging from seasonal changes to structural shifts in your home. One common cause is humidity, particularly in certain Australian climates where high moisture levels during summer can cause wooden doors and frames to swell. Over time, even slight swelling can make doors harder to open or close.
In addition, loose hinges, misaligned strike plates, or a buildup of dirt and grime can contribute to sticking. Shifting foundations, which are common in older homes, can also lead to misaligned doorframes. These foundational issues often require professional intervention, such as restumping or reblocking, to restore alignment and prevent further structural damage.
Steps to Fix a Sticking Door
If your door is sticking, follow these steps to troubleshoot and fix the issue:
- Inspect the Door and Frame:
Begin by identifying the problem area. Look for marks on the frame where the door is rubbing, and check whether it’s sticking at the top, bottom, or along the edges. Misalignment at the top right corner or bottom may indicate loose hinges or swelling, while the door sticking on the strike plate points to alignment issues. - Address Humidity and Swelling
During the warmer months, increased humidity can cause wooden doors to expand and stick. To fix a swollen door, remove it from its hinges and sand down the areas where it rubs against the frame. After sanding, apply a protective sealant or varnish to prevent future moisture absorption. Using a dehumidifier indoors during humid periods can also help reduce moisture levels and prevent the issue from recurring. - Tighten Hinges and Align Hardware:
Loose or worn hinges are another common culprit. Use a screwdriver to tighten the hinge screws, or replace them if they no longer hold firmly. If the door continues to sag, try replacing one of the screws with a longer one (around 3 inches) to secure it more deeply into the wall framing. Misaligned strike plates can also be adjusted by loosening and repositioning the screws. - Clean and Lubricate Moving Parts:
A door that’s sticky or hard to open and close may simply need cleaning and lubrication. Wipe down the door edges and frame to remove dirt and debris. Apply a silicone-based lubricant to the hinges to keep them moving smoothly without creaking. - Check for Foundation Issues:
If your door remains stuck after these adjustments, the problem may lie deeper, such as shifting foundations. Over time, a sinking or unstable foundation can throw doorframes out of alignment, causing persistent sticking. Professional restumping or reblocking services can help stabilise the foundation and correct alignment, ensuring that your doors close properly and your home remains structurally sound.
