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.

"Our experience was great, except for writing a big check to you! When Karen and I started the replacement procedure we wanted a quality product. We wanted a company with really, not just in theory, stands behind their work. After reading many reviews and visiting with several people we chose Renewal by Andersen. During the buying process we felt no high pressure. If we were repeating the process, we would change nothing. All the people we dealt with were knowledgeable and helpful. Dave and Amanda, we appreciate you taking time to explain options in style, color, cost, construction of product, installation process etc. Amanda, we are so glad you recommended the awning kitchen window. Dave, we love the invisible kitchen screen. Thanks. The crew of Nate, Colton and Mike were great! Not only were they competent and efficient workers, they were men we were glad to have in our house. Karen commented she never heard any of them say anything unprofessional or in poor taste. Each day and at the conclusion of the job, they thoroughly cleaned-up any mess. A big gold star to the three of you. You are a great team. The stain matches existing wood perfectly. Thanks for a good job, Dan. Robert, thanks for your contribution to the project."
