How to Adjust a PVC Window?

Published in Window Maintenance 3 mins read

To adjust a PVC (uPVC) window, particularly if it's sticking or you're trying to fix a draught, you can often adjust the position of the sash within the frame.

One common method involves adjusting the window's height or horizontal position using screws located on the side of the window frame, near the hinges or stays.

Adjusting Window Height or Position

Based on common methods and the provided reference, here is a step-by-step guide focusing on adjusting the panel's height:

  1. Open the Window Fully: Ensure the window is opened completely to access the adjustment screws on the frame.
  2. Locate Adjustment Screws: Look for screws on the left and right sides of the window frame, typically near the hinges or friction stays. The reference mentions 4 screws on the left and right side of the frame, suggesting these are the ones to target.
  3. Loosen the Screws: Use an appropriate screwdriver (often a Phillips head) to slightly loosen the 4 screws on the left and right side of the frame. You don't need to remove them, just make them loose enough to allow movement. This totals 8 screws that need loosening according to the reference ("tighten all 8 of the screws").
  4. Adjust the Panel Height: With the screws loosened, you can now raise or lower the height of the panel to adjust it. Gently manipulate the window sash to the desired position. This adjustment can help if the window is dragging on the frame or sill, or if it's not sealing correctly.
  5. Tighten the Screws: Once the window panel is in the correct position, tighten all 8 of the screws firmly. Ensure they are secure but avoid overtightening, which could damage the frame.
  6. Close and Test: Close the window and test its operation. Check if it opens and closes smoothly and if the draught issue is resolved. You may need to repeat the adjustment if necessary.

Why Adjust a PVC Window?

Adjusting a PVC window can resolve several common issues, such as:

  • Draughts: A poorly aligned window won't create a tight seal, leading to cold air entry. Adjusting can improve the seal. This relates directly to the reference's context of fixing a draughty uPVC window.
  • Sticking or Dragging: If the window sash is rubbing against the frame or sill, adjustment can reposition it to ensure smooth operation.
  • Difficulty Locking: A misaligned window might not engage its locking points correctly, making it hard to secure.

Remember that PVC windows can have different types of hinges and locking mechanisms, and some adjustments might require specific tools or knowledge. However, the method described using the side frame screws is a fundamental adjustment for many types of PVC windows.
