Ways to Fix a Sticking Sliding Patio Door

Sliding door tracks accumulate dirt, dust, pet hair, bugs, grass and other debris. Over time, this accumulation will make your door hard to open and close, even if it’s a high-quality door that was installed by a reputable door and window company.


Here are some ways you can fix this problem:Clean the Tracks

First, vacuum up any loose debris so you can see how much dirt there is. Then, grab a scrub brush and work around the corners of the tracks. You can use an old toothbrush or a grout brush that fits the track.  After brushing, vacuum the area again and wipe with a damp sponge. Make sure to open and close the door various times during the process to loosen up dirt in the rollers. 


Annually lubricate the locks, hinges and operators of your patio door. Doing so will help maintain the smooth operation of your door. Keep in mind that you should never use wet lubricants or harsh, solvent-based grease on Renewal by Andersen® patio doors and replacement windows.   

Adjust Rollers

Patio doors usually have at least one small hole at the top and bottom to let you adjust the roller height. These holes are typically covered with a plastic plug. Remove the plug then tighten and loosen the roller height using a screwdriver. Test the door each time you adjust the roller. 

Check the Warranty

Review your warranty if you’re unable to solve the issue yourself. Many doors and windows come with comprehensive warranties that include service or replacement part coverage.

"When we purchased 10 large windows from Renewal by Anderson, were able to do so because of the liberal finance plan offered. The work was done in a timely manner and they did a good cleanup. I would highly recommend them for any window replacement."
