Causes for why do composite doors suddenly become sticky
-
Temperature and Humidity Changes:
- Identification: Customers may notice that their composite door becomes difficult to open or close during periods of extreme temperature or humidity changes. The door might feel tight and require more force to operate.
- Solution: Pay attention to how the door behaves during different weather conditions. If sticking is more prominent during specific times, it’s likely due to temperature and humidity changes. Adjust the door’s fit during moderate weather to allow for expansion and contraction.
-
Warping and Swelling:
- Identification: Check for visible signs of warping, such as a misaligned door within the frame. If the door seems to rub against the frame at certain points, warping may be the cause. Swelling can also cause the door to feel heavier and less manoeuvrable. This is mainly due to thermal movement in composite and uPVC products. To find out more about thermal movement click here.
- Solution: Regularly inspect the door for any changes in alignment. If you suspect warping or swelling, ensure the door is well-sealed against moisture. Address any damaged or cracked portions of the door’s wood to prevent further warping.
-
Paint or Varnish Buildup:
- Identification: If the door seems to stick more around the edges or corners, excess layers of paint or varnish might be the culprit. Customers may notice visible buildup or uneven edges.
- Solution: Gently sand down any rough or uneven portions of the door’s edges. This will help to remove the excess paint or varnish that’s causing the sticking. Repaint or refinish the door to ensure a smooth surface.
-
Hinges and Hardware Issues:
- Identification: Examine the hinges and hardware for any signs of wear, rust, or misalignment. If the door doesn’t close evenly or makes creaking sounds, it might be due to worn-out hinges or hardware.
- Solution: Regularly inspect and lubricate hinges and hardware. Tighten any loose screws or bolts. If hinges are damaged or misaligned, consider replacing them to ensure proper movement.
-
Foundation Settlement:
- Identification: If the sticking issue is consistent and not easily attributable to weather changes, it might be related to foundation settlement. Check if the door frame appears uneven or if the door contacts the frame only in specific spots.
- Solution: If foundation settlement is suspected, consult a professional contractor or structural engineer. They can assess the foundation and recommend adjustments to the door frame or foundation to rectify the issue.
