How to Fix a Sticking Sliding Patio Door

Operable doors and windows can help in improving your home’s ventilation. However, over time, dirt, grime and damaged rollers can make them hard to open and close. 

Here are ways to fix a sticking sliding patio door. 

Clean the Door Tracks

Dirt, dust and other debris can settle in the sliding door tracks. They are not easy to clean so you’ll have to pull out at the stops. Vacuum loose debris, and then use a stiff brush to clean around the corners. You can use an old toothbrush or a grout brush. Vacuum the tracks again, and then clean with a damp sponge. Open and close the door a couple of times to loosen the dirt stuck in the hard to reach rollers.  

Lubricate the Track

Apply a dry lubricant on the locks, hinges, operators and rollers of your patio door once a year. This will help your door stay operable. Never use wet lubricants or harsh, solvent-based greases on Renewal by Andersen® replacement windows and patio doors. It will damage them and collect dirt or other corrosive debris. 

Adjust the Rollers

Sliding patio doors usually have one or two tiny holes at the top and bottom for adjusting the roller height. The holes are typically concealed with a plastic plug. Remove this plug, and, with a screwdriver, tighten and loosen the roller height. Make small adjustments, and test each time. Have someone hoist up the door as you adjust the roller height.

See Your Warranty

Check the warranty coverage for your sliding patio door if none of the fixes above worked. Most doors and windows have extended warranty and service or have replacement parts covered.

"We had most of our windows replaced and one door. I am so happy with not only the look of the windows and door, but also with the warmth and lack of air coming in. Craig McCormick and Levi did a great job. They were friendly, respectful and professional."
