The summer months are definitely the time of the year I’m contacted most about patio doors that are difficult to slide. Whether it be BBQ’s in the back garden or having every window and door in the house open to let in a summer breeze it’s no surprise to me that it’s when most problems happen with sliding patio doors and their rollers! In this guide I’ll explain how to change the rollers on an aluminimum sliding patio door – if you have a PVC sliding door then check out my guide and video on how to replace the rollers on a PVC sliding patio door here!
Aluminium Sliding Patio Door Rollers – Get Back on Track
So, the very first thing I check when I’m looking at a patio door that’s not sliding properly is to see if it’s rolling on the track. Sometimes a sliding door can partially jump off the track if it gets a bump from opening or closing it too hard. This is really only an issue on aluminium patio doors, as it’s not possible for PVC sliding patio doors to come off the track, because of the way they are made.
How To See If A Roller Is Off It’s Track
On aluminium sliding doors it can be difficult to see if the rollers are on the track. The roller will usually be located about 2 to 3 inches from each edge of the door. The wheel or wheels on the rollers are U shaped to sit down on the track. You have to get down on your hands and knees and look at the bottom of the door and you should see the wheels sitting on top of the track. If one of the wheels is not sitting on the track then lift the door straight up and at the same time push the bottom of the door in and let it back down. Check again to see if the roller is sitting back on the track. Test the door to see if it’s rolling freely again. If its still difficult to slide, then more than likely there is a problem with your rollers and they may need to be replaced.
How To Replace The Rollers on An Aluminium Sliding Patio Door
If your roller is on track but your patio door isn’t opening smoothly you may have to replace the rollers. The steps outlined below will explain how to replace the rollers on an aluminium sliding patio door step by step.
- Lift the door up and out off the track – Lift the door straight up, at he same time pull out at the bottom and let the door down on the ground.
- Lay the door down – If you have a set of saw horses you can lay the door on these. If not lay it down on some timber planks or cardboard to protect it from scratches.
- Remove the bottom section of the door – In the majority of cases the bottom section of the door will be screwed to the sides of the door. Remove the screw at either side of the door. Tap the bottom section down with a mallet or a piece of wood and a hammer.
- Remove the old rollers – With the bottom section off you will see two screws that hold the rollers. Remove these screws and remove the old rollers
- Select the correct sized replacement roller – Measure from the top of the roller to the bottom of the wheel/s. Select the low size if the measurement is between 30mm – 40mm. Select the high size if the measurement is between 40mm – 50mm.
- Fit the new rollers – Fit the new rollers to the bottom section of the door making sure that the height adjustment screw faces outwards.
- Re-fit the bottom section of the door – Slide the bottom section of the door back into place at the bottom of the door. Tap it back into position with a mallet or a piece of wood and a hammer. Re-fit the two screws on either side. Lubricate the new rollers.
- Re-fit the door on to the track – Stand the door beside the door frame. Lift the door straight up and into the top channel, pushing in at the bottom. Let the door back down on to the track
- Adjust the door to close level – Slide the door almost closed, until it leaves a small gap. Look at the gap at the bottom of the door and at the top. This gap needs to be the same to ensure the door locks and seals properly. If the gap is larger at the top than it is at the bottom. Adjust up the back roller height or adjust down the front roller height. If the gap is larger at the bottom than it is at the top. Adjust up the front roller height or adjust down the back roller height. To adjust the roller height, place a philips screwdriver in the slot below the bottom fixing screw. Try one turn of the screwdriver at a time and re-check the gap.
- Check that the door is locking – When your happy that the door is closing lever. Check that the door is locking. If the door doesn’t lock it means that the door might be adjusted too high or too low. Adjust the roller height the same amount of turns on each side and try the lock again.
