🔍 Quick Diagnosis – Identify Your Door Problem

Before attempting any door jamming fix, identify what type of door and what’s wrong.

Door type identification:

• Sliding door: Slides horizontally on a track. Used for patios, cupboards, room dividers.
• Hinged door: Swings open on hinges (side-hinged). Used for entrances, rooms, bathrooms.

Ask yourself these questions:

• Does the door hit the frame at the top, bottom, or side?
• Did the problem start suddenly or gradually?
• Has your house settled recently (new home, cracks in walls)?
• Has the weather changed recently (humidity, temperature)?
• Is the door hard to move (dragging) or does it hit something (obstruction)?

Quick reference: Symptom → Likely cause

According to SANS 10400 door alignment standards and SABS hardware standards, doors that don’t operate properly may be non-compliant with building regulations.

🧹 Sliding Doors – Dirty Tracks (Most Common Cause)

For sliding doors, dirty tracks cause 80% of aluminium door sticking issues.

How to fix:

1. Vacuum the bottom track thoroughly – use a crevice tool to reach deep corners
2. Use a stiff brush to dislodge caked-on dirt and debris
3. Wipe tracks with a damp cloth and mild detergent
4. Remove any stones, screws, or broken parts – common culprits
5. Lubricate with silicone spray (never oil – oil attracts dust)
6. Slide the door back and forth several times to distribute lubricant
7. Wipe away excess lubricant

Tools needed: Vacuum, brush, cloth, mild detergent, silicone spray (R80-150)

Time required: 5-10 minutes per door

Success rate: Very high – most sliding doors work perfectly after cleaning

Why tracks get dirty: Dust, sand, leaves, pet hair, insects, and debris accumulate over time. In dusty Highveld areas, tracks need cleaning more often. In coastal areas, salt residue adds to the problem.

🔄 Sliding Doors – Worn Roller Wheels (DIY Moderate)

If cleaning doesn’t help, worn rollers are the likely cause of aluminium door sticking.

Signs of worn rollers:

• Door sags – gap at the top when closed
• Door drags or feels “heavy” even after cleaning
• Grinding or scraping noise when sliding
• Door tilts in the track – one side lower than the other

How to adjust rollers (most have adjustment screws):

1. Locate the adjustment screws – usually at the bottom corners of the sliding door panel
2. Use a flathead screwdriver or Allen key (varies by manufacturer)
3. Turn clockwise to raise the door, counter-clockwise to lower
4. Adjust both sides equally – check for level after each adjustment
5. Test slide – adjust until door slides smoothly and seals evenly

How to replace rollers (if adjustment fails):

1. Remove the sliding door – lift up and swing bottom out (heavy – get a helper)
2. Remove the old roller assembly (usually 1-2 screws)
3. Take the old roller to a hardware store to match size (common sizes: 25mm, 32mm, 38mm)
4. Install new roller – ensure it’s seated correctly
5. Reinstall the door and adjust as above

Roller cost: R50 – R200 per roller (2-4 rollers per sliding door)

Time required for replacement: 20-30 minutes per door

Read our detailed roller replacement guide.

🚪 Hinged Doors – Frame Settling & Hinge Adjustment

Hinged doors can settle over time, causing door alignment issues.

Signs of frame settling:

• Door sticks at the top corner (hits the frame)
• Door doesn’t latch – latch misses the strike plate
• Gap at the top or bottom when closed
• Door closes but you see daylight on one side

How to adjust hinges (most have adjustment screws):

1. Locate the adjustment screws on the hinges – usually Allen key adjustments
2. Identify which axis you need to adjust:
   • Up/down adjustment – raises or lowers the door
   • Left/right adjustment – moves door towards frame
   • In/out adjustment – compression against weather seals
3. Make small adjustments (1/4 turn at a time) – don’t overtighten
4. Close and test – repeat until door seals and latches properly

Tools needed: Allen key set (usually 4mm or 5mm)

Time required: 5-15 minutes per door

Difficulty: Beginner – but requires patience for fine adjustments

What not to do: Don’t force adjustment screws – they turn easily. If you meet resistance, stop and call a professional.

For detailed guidance, read our hinge repair guide (similar principles apply to doors).

🔩 Failed Hinges or Corrosion (Call a Pro)

Some aluminium door sticking problems require professional attention.

Signs of hinge failure:

• Hinge is visibly bent or broken
• Rust or corrosion (common in coastal areas)
• Door sags despite full adjustment
• Crunching or grinding when operating
• Hinge pins have fallen out

Why call a professional:

• Hinge replacement requires removing the door (heavy – risk of injury)
• Matching replacement hinges – many proprietary sizes
• Proper alignment during reinstallation – critical for sealing
• Cost of mistake is high – damaged door or frame

Typical hinge replacement cost: R1,000 – R2,500 per door including labour and parts

For coastal areas: Specify stainless steel hinges – standard steel corrodes within 2-3 years

Use our repair services for hinge replacement.

📏 Floor Level Changes – Uneven Floor

Sliding doors are especially sensitive to floor level changes.

Signs of floor level issues:

• Door slides fine on one side, sticks on the other
• Door jams at the same spot every time
• Floor has visible cracks or settlement
• Recent flooding or drought (soil movement)

How to check floor level:

1. Place a long spirit level (1.8m+) across the track area
2. Check if the floor is level left to right
3. Check if the floor is level front to back

DIY solutions for minor unevenness:

• Adjust roller height to compensate for slight floor variations (up to 5mm)
• Check if track has twisted – may need resecuring

When to call a professional:

• Floor variation exceeds 10mm over 2m
• Multiple doors in the same area have problems
• Floor is actively settling (cracks growing)
• Signs of foundation problems

Professional solutions: Floor levelling compound, track planing, or structural repairs

🌡️ Seasonal Changes – Temperature & Humidity

Aluminium expands and contracts with temperature changes.

Why this matters: Aluminium has a high thermal expansion coefficient – it expands in heat, contracts in cold. A door that fits perfectly in summer may stick in winter or vice versa.

Seasonal sticking patterns:

• Summer (hot): Door may stick because the frame has expanded
• Winter (cold): Door may have gaps because the frame has contracted
• High humidity: Wood frames may swell, affecting door clearance

DIY solutions:

• Adjust roller height or hinges seasonally – 1-2 turns may be enough
• Use silicone lubricant – helps door slide despite minor expansion
• Ensure drainage holes are clear – prevents water buildup that expands when frozen

When it’s not normal: If seasonal changes cause major sticking (severe expansion/contraction), the door may have been manufactured with insufficient clearance. Call a professional to assess.

🏠 Structural Issues – Building Settlement

Sometimes the problem isn’t the door – it’s the house.

Signs of structural movement:

• Multiple doors and windows in the same area have developed sticking problems simultaneously
• Cracks in walls near the door (especially diagonal cracks above corners)
• New home (first 2-3 years settling period is normal)
• Recent foundation work or soil movement (drought, flooding, tree roots)

What to do:

1. Don’t force the door – you’ll damage it
2. Check if the door frame is still square – use a laser level or measure diagonals
3. If the opening has shifted, the door may need professional removal and reinstallation
4. Consider structural engineer assessment if multiple doors/windows affected
5. For new homes (under warranty), contact your builder

Repair approach for shifted openings:

• Minor shifts (5mm or less): Installer can remove and reframe the door
• Major shifts (10mm+): May require structural repair before door can be refitted
• Cost: R2,000 – R10,000+ depending on severity

✅ Prevention – How to Avoid Future Door Problems

Regular maintenance prevents most aluminium door sticking issues.

Quarterly (every 3 months):

• Clean tracks thoroughly – vacuum and wipe
• Lubricate sliding door rollers with silicone spray
• Lubricate hinged door hinges with silicone spray
• Clear drainage holes in tracks (prevents water buildup)
• Check for debris accumulation – remove immediately

Annually:

• Inspect all hardware – tighten loose screws
• Check for signs of corrosion (especially coastal areas)
• Test door operation – open and close fully
• Check latch alignment – adjust strike plate if needed
• For sliding doors, check roller condition

Every 2-3 years:

• Replace worn rollers in sliding doors (preventative)
• Replace weather seals (they perish over time)
• Professional service for multi-point locking systems
