Are Your Sliding Glass Doors All Glass and No Slide?

Have you noticed that the sliding glass doors in your home are China injection molding,laptop batteries becoming harder and harder to slide open? Are they more than 10 years old? Do they happen to be aluminum frame dual pane doors? Those doors are heavier due to the dual pane glass, but most of the aluminum units did not use stainless steel rollers. The rollers get rusty after a while, and start to bind.

To replace the rollers, you must remove the sliding panel from the opening. The fixed panel must be removed in order for the sliding panel to come out, in most cases. FIgure out whether or not your fixed panel has to come out as well. If the slider is on the inside track and the fixed panel is on the outside track, you will have to take out both panels, because the slider will only come out from the outside. There is a lip on the bottom of the track inside your house, that keeps water from coming in. However, that lip is also too high to lift the sliding panel up and over. Therefore, you will have to remove the fixed panel first, then lift and swing out the slider from outside. If you are one of the few who have a slider on the outside track, then you can lift your slider out without having to remove the fixed panel.

For now, let us assume that you need to remove the fixed panel first. To do this:

1) Remove your screen door if you have one.

2) Look for a metal piece on the bottom track that runs from the bottom corner of the fixed panel all the way across to the bottom of the side jamb that has the door lock hardware. If your door is really old, that piece might be missing. If there is one, pry it up from the track. Once that piece is removed...

3) Look inside the house where the fixed panel is against the wall jam -- look for screws holding the frame to the jam. Remove these screws, and place them where you won't lose them.

4) Pull the fixed panel out of the side jam.

5) Lift the slider up and out, just like you did with the fixed panel.

6) Once you get the slider out, nearly all rollers are held in place by the same screw that holds the frame corners together. So set the panel on one side, remove the screw in the corner, then flip the panel over, remove the screw on the other bottom corner. Now, using a rubber mallet or the wood handle of a hammer, tap the bottom frame off the glass. Now you have access to your rollers. Examine how they are inserted into the door frame. Remove only one roller to take with you to match when you shop for new ones. Then, you can use the roller that you left in place as a guide to installing the new ones.

7) Buy new rollers at someplace like Lowe's, Home Depot, Ace Hardware, or Orchard Supply Hardware. They should carry what you need. If they don't...

8) Have new rollers ordered. Bring the roller to your local glass shop. If they don't have them in stock, they can order them, which could take about a week. In that case, don't worry. Go home and tap the bottom frame back on the door panel, but leave the corner screws out. It's fine to leave out the roller that you removed. Just lift the door back in place, install the fixed panel, but don't snap the bottom piece back in, and don't install the inside screws. Then, from inside the house, just lift the slider and pull it closed. Don't drag it if you left the roller out. That will scrape the bottom track. Lift it just enough to take the pressure off, and close and lock it.

9) When your new rollers arrive, take everything back out. Install the new rollers. Before putting the door back in, adjust the new rollers all the way up. This way, the new rollers won't interfere with you lifting it back in place. Adjust the new rollers down until the door slides well and locks. There should be an equal gap at the top and bottom when the door is about an inch from closing into the side jam. The rollers can be adjusted to make this dimension even.

You may think this sounds expensive, but it doesn't have to be. Sliding glass door repair can be done by a professional for $50 or $60 including parts, so it may be worth hiring someone to do it. However, in high population areas, it may be typical to be charged $100 in labor only. They may also mark up the cost of the rollers, and you could end up paying $130 for a job that would only cost you about $20 to do yourself. Glass door repair does not have to be intimidating, or expensive. Good luck!
