The only time your Renewal by Andersen of Long Island replacement patio door panels should come off the track is when you intentionally remove them for routine maintenance or to trouble-shoot a problem. Checking patio doors about once a month will help ensure your doors slide open and closed effortlessly for many, many years. Anytime your new door sticks or seems tight, you should examine your track to make sure there aren’t any obstructions or damage.

Patio Door Maintenance Check List

  1. To ensure they’re not in the way or get damaged during your inspection, it’s best to take down window treatments – curtains, blinds, shades, etc. – before inspecting your patio door.
  2. Careful remove your door insect screen(s) and place them in a safe place until you are ready to reinstall them after cleaning.
  3. If you opted for removable grilles when you designed your replacement patio doors, and you want to clean the glass panels at the same time, lift the grilles away from the glass near the edge of the frame. Clips are permanently affixed and you should not try to remove them. If you need more detailed instructions on safely removing and reinstalling your grilles, watch this video.
  4. Inspect the tracks for corrosion, chips or divots. The bottom of the track – the part where the door panels slide – should be flat, debris free and firmly in place. If you find rust or corrosion on the two parallel bars on either side of the flat bottom that create the sliding space, use a narrow high-quality wire brush to address areas that could be causing the door to stick.
  5. Use a small brush-type vacuum attachment or wand to remove loose dirt, leaves and other debris in the “valley” of the track.
  6. Wipe the area with a soft, damp cloth. If you find it hard to remove sticky or greasy spills, use a mild soap and water solution. Never use harsh chemicals or sharp objects to attack stubborn stains.
  7. Dry the tracks and test the door operation.
