What Type of Sliding Doors Do We Repair?

Glass and aluminium sliding door specialist

The Sliding Door Doctor fixes original glass and aluminium sliding doors leading to backyards, verandas, decks, and patios. We work on residential doors of all ages. Because our vans carry a massive range of parts, doors up to 40 years old can be repaired successfully.

Our technicians can also service your flyscreens or security screen doors on the same visit, saving you from booking a second trade. Please note that we focus strictly on external residential doors, so we do not repair internal doors or replace smashed glass.

Save Thousands by Repairing, Not Replacing

Repaired, not replaced

Most stuck sliding doors do not need replacing because while moving parts wear out over time, the heavy aluminium frame is built to last for decades. We can restore your original door to run smoothly at a fraction of the cost, saving you from a pricey and completely unnecessary replacement.

Take our customer Howard as an example. He was quoted $6,000 by a replacement company to tear out his old frame and install a new one. We were able to repair his existing door for a tiny fraction of that price, and Howard later noted that it now slides better than it ever has.

Getting this result doesn’t require a major renovation or days of construction. An average repair takes our technicians just 1.5 hours on-site, and we test the door thoroughly before we leave to make sure you can slide it with one finger. Contact us today to request a free quote online.

Common Sliding Door Problems and How We Fix a Sliding Door Properly

Mechanical breakdown of sliding door issues

Sliding doors handle heavy daily use and constant exposure to weather. We focus on fixing the specific moving parts that cause your door to stick, using heavy-duty components that last.

Door Won’t Slide or Feels Heavy

Dirt, dust, and pet hair build up in the bottom track. This grit grinds against the rollers, creating flat spots and making the door heavy to push. We replace rollers rather than patch them to restore smooth movement.

Dropped Sliding Door

Worn rollers let the door sit low and drag along the metal frame. Adjusting the side screws only hides the problem for a short time once the internal wheels are worn down. We fit new dual-tyred rollers rated at 100kg each to lift the door back to its correct height and get your locks lined up again.

Door Off Its Track

A door pops off its path when the metal track becomes scratched, gouged, and bumpy over the years. We repair the track with a solid stainless steel cover cut to size rather than replacing the whole frame. This creates a perfectly smooth track for the new wheels.

Worn or Broken Rollers

Plastic rollers degrade, crack, and split due to age and weight. Rollers on doors up to 40 years old can be replaced with premium Australian-made parts. Our mobile vans carry the complete range as standard to ensure a successful fix on our first visit.

Frequently Asked Questions About Our Sliding Door Services

How much does it cost to repair a sliding door?

The total cost depends on whether your door requires new rollers, a track rejuvenation cover, or both parts replaced. We give an honest, fixed quote over the phone before booking your visit. Our $0 call-out fee means if we can’t fix it, you don’t pay. Repairing your existing door costs a fraction of what a full door replacement runs to.

Can I fix a sliding door myself?

You can do a basic maintenance check by vacuuming and cleaning the bottom track to test the door. If it still drags or grinds, the internal rollers are worn. You must lift the heavy glass door completely out of the frame to replace them. This is heavy two-person work where glass can easily get damaged. Our professional repair takes around 2 hours and carries a 3-year warranty.

What is the most common problem with sliding doors?

The most common issue is a door becoming sticky, heavy, or difficult to slide. This problem is caused by dirt building up in the track and worn, damaged, or misaligned rollers. When the rollers flatten or crack, they stop rolling and begin dragging across the track.

How do you fix a sliding door that won’t slide?

We remove the door from its frame, replace worn rollers with dual-tyred wheels rated at 100kg per roller, and fit a stainless steel track cover cut to size. This combination completely removes the friction. Your door will slide smoothly using just one finger.

How do you fix a sliding door that has dropped?

A dropped door means the internal rollers have worn down or collapsed entirely. Adjustment screws only mask this failure temporarily before the door drops again. We replace the rollers with heavy-duty parts so the door sits at the correct height and your security locks align perfectly.

How do you fix a sliding door that has come off its track?

This issue is usually caused by a damaged or worn track combined with broken rollers. We fix the existing track with a solid stainless steel cover rather than replacing the door frame. The door is then re-hung on brand-new rollers to ensure it stays on its path.

How long does a sliding door repair take?

A standard sliding door repair takes around 1.5 hours on average to complete. Our service vans carry the full range of Australian-made rollers and track covers. This means we can complete the entire job in one single visit.

Do you replace sliding doors or only repair them?

We repair, don’t replace. Our whole focus is on saving your original door frame to keep your costs down. Most doors, even those up to 40 years old, can be restored to perfect working order. We do not repair internal doors or smashed glass.
