5 common patio door problems

1. My patio door won’t open

If your patio door won’t open, don’t force it. This is a common issue and can be repaired without damage. Typical causes include:

• Gearbox failure in the multi-point locking system (average lifespan 10-12 years)
• Door alignment issues that cause strain when locking or unlocking
• Cylinder failure where the key won’t turn or release the mechanism

I have specialist tools and experience, and can fix these problems quickly and safely.

2. My patio door won’t lock

A patio door that won’t lock is one of the most common faults we see. In many cases, the issue is either:

• A failed locking mechanism
• A door alignment problem

To check, lift the handle while the door is open:

• If the locking points engage, the issue is likely due to alignment
• If they don’t, the mechanism may have failed

Either way, a patio door that won’t lock can be fixed without replacing the door.

3. Broken patio door handle

If the handle has come away completely, it will need replacing.

• High-quality replacement handles are supplied and fitted
• Correct fit for security and appearance
• Wide range of handle styles and finishes available

If the handle spins but doesn’t unlock, the problem is often in the locking mechanism. This is a common issue and can be easily fixed.

4. My key won’t turn in the patio door

Many modern patio doors use high-security cylinders. This isn’t a DIY fix, as forcing the key can cause further damage. When these develop a fault:

• The key may refuse to turn
• The mechanism may not release

Correct diagnosis and professional replacement restore smooth, reliable operation.

5. A draught is coming from my patio door

Misaligned doors can let gaps form around the frame, allowing:

• Cold air in
• Warm air out

This will increase heating costs.

Realigning the door will therefore:

• Restores a proper seal
• Improves operation
• Returns the door to original performance

Can you repair old aluminium sliding doors?

This can be more challenging. Many older aluminium sliding doors use obsolete components, limiting repair options. In some cases:

• You can add locks at the top and bottom
• This will boost security
• It can also extend the door’s lifespan

But if the sliding tracks wear down significantly, repairs often become cost-ineffective. In those cases, the better long-term option may be to replace it. I will advise you honestly if this is the case.
