How to Install Rollers on Sliding Glass Doors

Tilda Publishing

All sliding glass doors will require a form of repair at some point. They become increasingly difficult to open and shut with time. The most typical issue is that the rollers on which they glide wear out, becoming so challenging to move that weaker figures like kids could scarcely get the sliding door open. Even worse, the doorknob could snap off from overuse.
Replacing the rollers on the bottom of external glass doors can get pretty time-consuming. While you can quickly go online to look for a glass door repair service, nothing feels more fulfilling than being able to handle an inevitable issue on your own.

How to Replace Sliding Glass Door Rollers

Depending on the door type, like vinyl or metal, architectural specifications and installation processes differ. However, in general, rollers replacement or installation DYI projects usually include:

Unscrewing and removing the movable panel's metal stiles;
Lifting the door from the bottom rail across to access the rollers' screws;
Removing the rollers;
Identifying the design specifications so as to purchase the right rollers;
Replacing the rollers; and
Fitting back the door
Adjust the rollers so that the door rests evenly in the frame.

To properly replace the rollers of a door or set of doors, removing the door is ultimately the first step as this makes swapping out the older rollers for newer ones easier.

Removing the Door

Removing the door is the easiest step and here's how to go about that.
1. Remove the glass portion of the door, which has accident-preventing benefits. This step involves:

Removing the glazed portion of the door.
First, slide a flathead screwdriver or a knife with the right tip under each wheel and press up.
Raise the door off its tracks by grasping each side of the framework.

2. Carefully remove the track from the glass door's frame but note the following:

If the plate can't be found, it's possible that the door doesn't have one.
If there's one, replace the screwdriver with a drill. Set the drill to reverse to extract screws.

3. Remove the headstop, which is a steel strip that runs along the top end of the frame and holds it upright.

Pull the bolts out of the headstop, and it should come out easily. But prevent the door from tumbling down, which could result in a compulsory glazing repair if the glass shattered.

4. Turn the adjustment screw counterclockwise to raise the rollers. There could be one or two adjustment screws.
5. Gently remove the door and place it on a table. Ensure to:

Hold either side firmly.
Lift the glass door up and out.
Place the door on a table or bench that's big enough.

Replace Rollers in Vinyl Doors

People choose vinyl glass doors for architectural reasons, from aesthetic adaptability to low maintenance needs. Nevertheless, the roller problem comes knocking and needs replacing sooner or later. Here's how to do that:
1. Using a screwdriver, remove all screws keeping the rollers in place. The screws may be situated on the lower part of the door.
2. To determine the kind of rollers, remove them from the door. Examine the rollers search for "glass doors UK" online to find a variety of shapes, sizes, and brands.
3. Replace the rollers at the base of the door and screw them in place.
4. Return the door on its track. Position the door so that the rollers are in contact with the track. Tighten nuts that were loosened or removed during the removal of the door.
5. Lower the rollers by turning the adjusting screw clockwise.

Replace Rollers in Aluminum Doors

Single wheel rollers are used in most aluminum sliding glass doors and are one of the requirements to note. As for glass doors in general, the best approach to determine which rollers are needed is to remove the rollers, purchase substitutes that match, and install them.

Using a screwdriver, remove any bolts on the rollers. Rotate every screw as counterclockwise as possible. The rollers might emerge on their own.
Using a hammer and wood wedge, unscrew the lower panel of the doorway. Place the thin edge of the woodblock against the roller-containing panel's top lip.
Determine the sort of roller you require, as described previously, by comparing and online. Go for "internal glass doors UK" or any specific search phrase.
Insert the new rollers into the panel's underside. Install the new rollers using the former as a reference.
With a soft hammer, tap the panel back onto the glass.
Screw the rollers into the door's side.
Replace the door on its track. Return the door to the higher track before lowering it to the lower track.
The rollers should be adjusted so that the door moves easily.

Note that these steps would work for any sliding door in any type of building. What matters is to know the type of glass door you have as previously explained.
