Why is your sliding shower door stuck?

Why your sliding shower door is stuck

A sliding shower door sticks when something stops its rollers from running freely along the track. Most of the time, that is a build-up of hair, soap scum and grit. For a jammed sliding shower door, HDB's home care guide to toilet fittings advises removing hair and solid particles from the moving parts or sliding track, and engaging a contractor to replace worn rollers.

If the door still sticks after cleaning, look for one of these:

• Worn rollers. Every sliding shower door roller wears down with use. A worn one may grind, wobble or leave the door sitting low at one end.
• A loose bracket. The brackets that hold the rollers or the track can work loose. The door then tilts, rubs against the frame or catches part of the way along.
• A bent bottom guide. The guide at the bottom keeps the glass running straight. If it has been knocked out of shape, the door can bind or jump off the track.

Slide the door slowly to see where it catches. Grinding all the way along suggests the rollers, while catching at one spot suggests a bracket or the guide.

Clean the track and rollers

Cleaning is the first fix to try. You need only a soft brush, a cloth and warm water.

1. Remove loose hair and grit. Slide the door to one side and pick hair and grit out of the exposed track with a tissue or an old toothbrush. Then slide it across and clear the other end.
2. Scrub the track. Use a soft brush and warm water to loosen soap scum in the corners and along the bottom guide. Avoid metal scrapers, which can scratch the track and the glass.
3. Wipe the rollers. Wipe each roller and its housing with a damp cloth, and pull away any hair wound around it that you can reach without lifting the door.
4. Rinse, dry and test. Rinse the track with clean water and dry it. Slide the door gently from end to end to check that it runs smoothly.

Wipe the glass and the sealant around the screen while you are there. HDB's toilet fittings guide recommends cleaning glass and sealant to prevent fungi growth. If black spots have already appeared on the sealant or tile joints, see how to remove bathroom mould.

Shower door repair: rollers, brackets and seals

If the door still drags after a thorough clean, a part has probably worn out or worked loose. HDB's toilet fittings guide gives these maintenance tips:

• Replace the sealant or gasket when it is detached or torn.
• Tighten brackets and hinges when they become loose.
• Engage a contractor to dismantle, alter or modify a tempered glass shower screen, and to replace worn-out parts.

Tightening a loose bracket screw can stop a door from tilting. Stop if the glass shifts or has to be lifted.

Shower screen roller replacement is different. It usually means taking the glass panel off its track, which is heavy work with a risk of breakage, so leave it to a contractor who works with tempered glass. Ask whether the job includes new guides if the old ones are worn.

Seals matter too. When shower screen sealant joints turn yellowish or black and water leaks through, HDB puts it down to dirt, fungi growth or loss of sealant adhesion, and advises clearing dirt regularly and replacing the old sealant. For that job, see silicone sealant replacement.

Safety with glass doors

Until it is fixed, keep children away and tape a clear warning across the glass so nobody uses the door. Do not lean on the panel or try to lever it back onto the track with a tool. A chipped edge or a crack is also a reason to stop using the door and call a contractor.

If you live in an HDB flat and plan to replace the screen and kerb as part of new bathroom floor finishes, HDB's renovation guidelines for building works require pre-packed waterproofing screed and a waterproofing membrane before the new floor finishes are laid, with the membrane turned up at least 150mm against walls and kerbs.

For everyday care, see these tips on bathroom maintenance to prevent leaks.

Who to call

A handyman or a glass contractor can replace worn rollers and guides and tighten loose brackets. Leaks through the joints of the screen need sealant work, so ask whether the company handles that as well. Compare companies on the door and window repair page, and check that the services they list cover shower screens or sliding doors.

When you get in touch, say whether the door drags, tilts, leaks at the base or has come off the track, and send photos of the rollers and the bottom guide. The cost depends on the job and the parts needed, so ask for the price before work starts and whether it includes parts.
