7 Maintenance Tips for Sliding Patio Doors



Sliding glass doors are a beautiful asset to your home but they do come with the task of keeping them clean etc.


Here are a few simple things you can do for regular upkeep and so they can be in great condition for years to come.


7 Tips


  1. Keep the Glass Clean

    Clear views through your patio doors start with clean glass. Regularly remove fingerprints and general dirt and grime with a quality window cleaner and a newspaper for a streak-free shine.

    Cleaning the glass regularly also helps prevent debris buildup in the frame and tracks.

    2. Maintain the Frame

    Wiping down both the interior and exterior frames of your sliding patio doors on a regular basis will not only keep them looking clean but also prevent weather-related damage to the outer frame seal.

    Use a gentle solution of warm, soapy water to remove dust and dirt, avoiding harsh chemicals that can harm the
    door's finish. For wooden frames, consider re-varnishing as needed to maintain their integrity, which will also keep away wood rot.

    3. Clean the Tracks

    The tracks of sliding patio doors will accumulate dirt, debris, and even pet hair over time. Regularly clean the tracks and rollers using a vacuum cleaner to remove loose debris, followed by a warm, soapy water solution to wipe away dirt. Use a butter knife or an old toothbrush to reach into grooves and tight spaces for a thorough clean.

    4. Lubricate the Tracks

    To keep your sliding glass patio doors sliding smoothly, lubricate the bottom tracks periodically. However, it's important to clean the tracks before applying any lubricant to prevent buildup that can cause sticking. Avoid lubricating aluminum tracks, as this can lead to problems with the rollers.

5. Replace Worn Weatherstripping

Damaged or worn weatherstripping can destroy the insulation of your
sliding patio doors. Replace weatherstripping when needed by removing old strips, cleaning the surface, and installing new weatherstripping according to the manufacturer's instructions.

6. Address Worn Rollers

If your sliding patio doors are difficult to open or close, worn rollers may be the reason. Clean and lubricate dirty rollers, but if they're damaged, replacing them may be necessary. Make sure you have a good alignment of new rollers for seamless movement.

7. Check Door Alignment

Misalignment happens due to various factors, including impacts, improper installation, or debris buildup. Check the alignment of the door panels regularly and adjust the roller screws as needed. For significant misalignment, consider a professional repair.
