A sliding glass door is a classy choice, especially for modern or contemporary homes. Fortunately, the sliding glass doors of today are better designed than their older counterparts, so you can expect to encounter fewer problems with this type of door. But of course, despite being high-quality and having a long service life, your sliding glass door may still develop problems, especially as it gets older.

In this post, Renewal by Andersen® of Denver — a trusted provider of replacement windows and patio doors — discusses some of the most common reasons for sliding door failure.
Wrong Lube
Sliding doors tend to malfunction if the wrong type of lube is used in the bearings. That said, it is important to ensure proper lubrication so that the bearings can roll smoothly. Using the wrong lube can produce undesirable friction, which can cause excessive heat, metal fatigue and wear.
Alignment Issues
When your sliding door falls out of alignment, make sure to have it adjusted immediately so as to maintain a proper roll. Alignment issues are typically the result of everyday wear and tear, loose screws or bad installation.
Poor Installation
Similar to windows, poor installation can also lead to a number of issues in sliding doors. To prevent wasting your money on faulty installation, make sure that you get to know the contractor before hiring them for the job. Check their qualifications and experience. Their previous projects will surely help you gauge the quality of their work.
Hair in Bearings
This problem often shows up in homes with pets. The hair of dogs or cats get caught in the bearings, and over time a buildup of their hair is formed in this part of the sliding door. This can make it difficult to open or close the door, and eventually it can cause the bearings to stop rolling completely. Make sure to clean every part of your sliding door regularly in order to prevent pet hair buildup in the bearings.
