How to Fix a Sliding Patio Door That Sticks

When it comes to windows and doors, proper operation is important. However, your sliding patio door can start sticking down the line, posing not just inconvenience but security risks as well, especially if it means your door is difficult to close all the way. Here’s what you can do to remedy the problem:

  • Clean the Tracks – A lot of the time, difficult operation can be attributed to simple dirt and debris buildup. As a sliding patio door relies on tracks to operate, dust, food crumbs, pet hair and other buildup in the tracks will hamper smooth operation. When your sliding patio door starts sticking then, check the tracks for buildup and clean what you find. A quick vacuum should do the trick but you can also use a stiff scrub brush to get into corners and get rid of deep-seated buildup.

  • Lubricate Moving Parts – Once your sliding patio door’s track is clean, you can move on to lubricating it with a silicone-based product. Start by applying a bit of the lubricant and then sliding your patio door back and forth to distribute the product. Using a silicone-based lubricant on replacement windows and sliding patio doors is ideal because it works well but doesn’t attract dirt like oil-based lubricants.

  • Adjust Rollers – Look for a small hole or two at the top and bottom of your sliding patio door to adjust roller height. Using a screwdriver, you can tighten and loosen rollers as you see fit, depending on your preferences.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
