A sliding glass patio door is an ideal investment, provided that it is installed in the correct position. It should be situated in such a direction that more light and air enter the room.

Nevertheless, with the development of sophisticated technology and building materials, superior quality and durable sliding patio doors are introduced in the market. Installing these doors not only aid in saving energy, but you can also enjoy the scenic view of gardens and outdoors without stepping out of home.

Understanding the parts of the door and its working will help in correcting the malfunction easily. In most of the sliding glass door designs, plastic rollers are configured either at the bottom, or both at the top and bottom of the door for free sliding.

The need for repairing a sliding glass patio door after some years of installation is understandable, particularly that of the tracks and rollers of the door unit. If you are planning to repair a sliding glass doors on your own, make sure you take the help of a friend or a family member. Remember glass doors are very heavy and they can be difficult to handle.

If the wheels are out of track, then you can troubleshoot the sliding door malfunction by simply adjusting them on the track.

Replace the Rollers: At times, the rollers or wheels may be worn out, which is more common in older door units. Carefully remove the damaged rollers from the frame with the help of a screwdriver. Purchase correct size rollers, preferably the exact copies of the damaged ones, and install them in the door framing as per the manufacturer's instructions.

Additional Contact Point: If your patio door is an old model, it is quite possible that it has only one contact point. This configuration reduces the durability of the wheels as the weight of the glass door is concentrated on the single contact point. You can install an additional contact point to ensure proper distribution of the door weight, which will increase the durability of the wheels. If this project sounds challenging, don't hesitate to hire a professional.

Clean the Tracks: Accumulation of dust and dirt in the tracks may be one of the causes of difficulty in sliding the door. If such is the case, you can vacuum clean the tracks for removing loose dust and dirt. Also, consider washing the tracks with a mild cleaning product and warm water. Allow them to dry properly before mounting the sliding glass patio door.
