How to Adjust a Patio Door

If your patio door is rubbing against the frame or not sliding properly, don't worry! Adjusting the door to fix this issue is easier than it seems. Whether you're raising or lowering the door to ensure smooth sliding, this handy guide from Centra Install Pros will show you how to make the necessary adjustments to restore your patio door’s function and prevent further wear.

Step-by-Step Instructions: How to Adjust a Patio Door

Adjusting the Height of the Patio Door

If your patio door is rubbing against the frame, it's likely that the door needs balancing. This can be done by adjusting the height of the door to ensure the wheels are properly aligned with the frame.

• Locate the screws: At the bottom of the patio door frame, you should find two screws on both the front and back of the sliding door. The top screw holds the wheels in place, while the bottom screw controls the door’s height.
• Adjust the bottom screw: Use a Robertson screwdriver to adjust the bottom screw on each side of the sliding door.
• To raise the door, turn the bottom screw clockwise.
• To lower the door, turn the bottom screw counterclockwise.

Pro Tip: Check the door's alignment with a spirit level on the lip of the door to ensure it is balanced properly.

Adjusting the Back Wheels of the Patio Door

Once the door is balanced, you may need to adjust the wheels on the back side of the door to ensure smooth operation.

• Adjust the bottom screw: Use the same technique as above to raise or lower the back wheels by turning the bottom screw on the backside of the door.
• Remove the security foot lock (if applicable): If your patio door has a security foot lock, you may need to remove two screws using a Robertson screwdriver to access the screws on the frame underneath.
• Reassemble the door: Once you’ve adjusted the back wheels, replace the security foot lock and test its functionality.

Why Adjusting Your Patio Door is Important

Adjusting your patio door can prevent it from rubbing on the frame, ensuring smooth operation and extending the lifespan of both the door and the frame. Here are the key benefits of maintaining your patio door:

• Smooth operation: Proper adjustment ensures the door slides smoothly without rubbing or sticking.
• Prevents door damage: A rubbing door can cause wear and tear on both the door and the frame, leading to costly repairs.
• Improves security: A properly adjusted security foot lock ensures your patio door is securely locked when not in use.
• Extends door lifespan: Regular adjustments help keep your patio door in optimal condition, preventing long-term damage.

Common Patio Door Adjustment Issues and How to Fix Them

While adjusting a patio door is usually straightforward, some common issues may arise. Here’s how to address them:

• Door still rubbing after adjustment: If the door continues to rub on the frame after adjusting the screws, check the wheels for dirt or debris that may be causing the obstruction. Clean the wheels and the tracks thoroughly before readjusting.
• Sticking foot lock: If the security foot lock isn't catching properly, it may need to be adjusted. Loosen the screws and adjust the foot lock up or down until it lines up with the hole. Make sure the screws aren’t overtightened, as this can pinch the lock and prevent it from functioning.
• Uneven door height: If the door isn’t evenly adjusted on both sides, double-check the screws on both sides and ensure they are adjusted to the same height.

Pro Tips for Maintaining Your Patio Door

• Regular adjustments: Check your patio door every 6-12 months for signs of rubbing or uneven height, especially if you notice difficulty in opening or closing the door.
• Keep the tracks clean: Regularly clean the door tracks to prevent dirt and debris from obstructing the wheels and affecting the door’s operation.
• Lubricate the wheels: Apply a small amount of silicone-based lubricant to the wheels and tracks to help the door slide smoothly.
• Choose quality doors: Centra’s doors are custom-made, highly durable, and backed by our unrivalled 30-year warranty. Designed with the end-user in mind, they are built to minimize maintenance needs.
