Armored door maintenance: how to preserve its longevity?

An armored door is an excellent investment in home security. It offers optimum protection against burglary attempts, while improving your home’s thermal and acoustic insulation. However, for an armored door to retain its performance and strength over the long term, it must be properly maintained. Regular maintenance not only prolongs the life of your armored door, but also ensures its smooth operation. In this article, we explain how to maintain your armored door to preserve its longevity.

Why is maintenance of an armored door important?

Armored doors are subject to a variety of conditions, including daily wear and tear, weather conditions, and intrusion attempts. Neglected maintenance can lead to malfunctions, premature wear of the mechanism or structural damage to the door. Regular maintenance allows you to :

Ensuring security: A poorly maintained door can become vulnerable and less effective against burglary attempts.
Preserving aesthetics: Maintenance keeps the door in good condition and prevents signs of deterioration.
Improve durability: Regular maintenance helps extend door life and avoid costly repairs.

Essential steps for maintaining an armoured door

1. Clean door regularly

An armored door, especially one exposed to the elements, accumulates dirt, dust and residues. To maintain its efficiency and appearance, it’s important to clean it regularly.

Clean with a soft cloth: Use a soft cloth or damp sponge to clean the door surface. Avoid using abrasive products that could damage the finish.
Use a suitable cleaner: For metal doors, a metal cleaner or a specific product for armored doors is recommended to remove rust or stubborn stains.
Dry properly: After cleaning the door, dry it thoroughly to avoid moisture, which can lead to rust, especially on metal doors.

2. Lubricate mechanisms

The internal mechanisms of the armored door, such as the lock and hinges, need to be lubricated regularly to prevent wear and ensure smooth operation.

Lock lubrication: Apply a silicone- or graphite-based lock lubricant to the lock cylinder. This will reduce friction and prevent the mechanism from jamming.
Lubricating the hinges: The door hinges also need to be lubricated to prevent squeaking and make it easier to open and close the door. Use hinge oil or spray lubricant.
Lubrication frequency: Lubricate the hinges and lock approximately every six months, or more often if the door is used frequently.

3. Check seals

The seals around the door play a key role in thermal and sound insulation. Over time, these seals can wear out or deteriorate, which can affect the door’s efficiency.

Check the condition of the seals: Inspect the rubber or silicone seals around the door. If they are cracked or damaged, replace them to maintain good insulation.
Clean seals: Use a damp cloth to clean the seals and prevent dirt build-up, which could compromise their efficiency.

4. Check locking mechanism

The locking mechanism, especially the lock, needs to be checked to make sure it’s working properly. Ineffective locking can compromise the security of the armored door.

Test the mechanism: Check that the lock engages and disengages correctly, and that the locking points operate smoothly.
Check for cylinder wear: If you notice resistance or difficulty in inserting the key, this may indicate that the cylinder is worn. In this case, it’s best to call in a professional to replace it.
Call in a locksmith: If you have a problem with the locking mechanism, it’s advisable to call in a locksmith to inspect the lock and carry out maintenance or replacement.

5. Check safety features

Armored doors are often fitted with additional safety devices such as cylinder protectors, reinforcing bars or metal plates. These elements need to be checked regularly to ensure they are in good condition.

Check the strength of the reinforcing bars: Check that the reinforcing bars are still secure and in good condition. They are essential to reinforce the door against break-in attempts.
Inspect metal plates: If your armored door is equipped with metal plates, make sure they are not damaged or corroded.

6. Protect against moisture and rust

Moisture can damage an armored door, especially if it’s made of metal. Rust can not only affect the door’s appearance, but also its efficiency.

Protect against moisture: Make sure the door is protected from excessive humidity, by regularly cleaning areas likely to retain moisture, such as door edges or hinges.
Apply an anti-rust product: If your door is made of metal, apply an anti-rust product once a year to prevent rust from forming.

Conclusion

Regular maintenance of an armored door is essential to preserve its longevity and ensure that it continues to perform its security function optimally. By cleaning the door, lubricating the mechanisms, checking the seals and inspecting the lock, you can keep your armored door in good condition for many years to come.
