Door Chains
Door Chain Fitting & Repairs by Trusted Locksmiths
Secure your front door with a professionally fitted door chain.
Door chains allow you to partially open your door while maintaining control over who enters, giving you added peace of mind — especially for vulnerable individuals or those living alone. At CJW Locksmiths, we supply and install strong, reliable door chains on all types of residential doors, including uPVC, composite, and wooden frames.
Whether you’re upgrading old hardware or fitting a new chain for the first time, our locksmiths ensure correct alignment and secure fixings. We use only approved products and carry out installations with precision and care.
Our door chain services include:
- New door chain installations
- Replacement of damaged or loose chains
- Realignment and reinforcement for improved security
- Advice on alternative door restrictors and access control
- Fast-response emergency locksmith service
For total reassurance, we also offer a full Home Security Check to assess locks, handles, and door fittings across your property.
What Is a Door Chain?
Add peace of mind with a simple yet effective home security solution. Door chains let you speak to visitors and check identification before fully opening your door — offering added control, discretion, and confidence.
A door chain is a small but vital security fitting, mounted between the door and frame. It restricts how far the door can be opened from the outside, creating a secure barrier while still allowing you to communicate with whoever’s on the other side.
Often fitted to front doors, flats, and elderly residents’ homes, door chains provide an essential safeguard — especially when paired with night latches or high-security locks.
Additionally, modern options are available in brass, chrome, or satin finishes to match your existing door hardware.
Fast, Friendly Service
No Job Too Small
Why Install a Door Chain?
✅ Improved Front Door Security
Adding a chain makes it harder for anyone to force entry if you open the door slightly. As a result, you gain more time to react in case of suspicious behaviour.
✅ Peace of Mind for the Vulnerable
Older adults or people living alone benefit greatly from this extra protection. For example, it allows them to verify callers before unlocking fully.
✅ Low-Cost, High-Impact
Door chains are affordable and quick to install — but make a big difference. Therefore, they’re a smart addition to any home security setup.
Door Chain Fitting – Our Process
Step 1: Advice & Selection
We assess your door material and advise the best chain for your needs, whether brass, chrome, or reinforced steel.
Step 2: Professional Installation
Your locksmith will carefully install the chain using secure screws and fixings that resist tampering.
Step 3: Testing & Adjustment
We ensure the chain functions smoothly, without scraping or sticking. Additionally, we test alignment and tension to avoid unnecessary wear.
Step 4: Safety Tips & Aftercare
Before we leave, we’ll demonstrate proper use of your new chain and provide tips for long-term maintenance. For example, regular checks for loosened screws or rust help keep the chain reliable for years to come.
Which Doors Can Have Chains Fitted?
Door chains can be fitted to most timber or uPVC doors. However, certain composite or fire-rated doors may require alternative solutions — such as door viewers or advanced security hardware.
If you’re unsure what’s suitable for your property, we’re happy to provide tailored advice. We also offer additional services like window lock repair and door handle upgrades.
FAQs – Door Chains
Are door chains easy to use?
Yes. Most operate with a simple slide or hook mechanism, making them ideal for all age groups.
Can you install a chain on a uPVC door?
In most cases, yes — but we always assess the door first to avoid damaging internal reinforcements.
Do door chains work on double doors?
Typically not, but there are alternative restrictors available. We’ll suggest the best option during your appointment.
How long does fitting take?
Fitting usually takes under 30 minutes. In fact, we often install door chains during lock changes.
Can I still use a door chain if I have a night latch?
Absolutely. In fact, combining the two increases front door security without major changes to your setup.
Is a door chain enough on its own?
It’s a useful layer, but not a full solution. We recommend combining it with solid locks, viewers, and reinforced strike plates.
