How to Maintain Your Security Door for Long-Lasting Protection

Expert Maintenance Tips from Aztec Mfg in Pueblo, CO

A security door is a long-term investment in safety, durability, and curb appeal. With proper care, your door can continue performing and looking great for many years. Routine maintenance is simple, but it plays a major role in preventing wear, preserving the finish, and ensuring smooth operation.

At Aztec Mfg in Pueblo, Colorado, we build security doors designed to stand up to everyday use and Southern Colorado’s climate. The following maintenance tips are based on best practices to help you protect your investment.

Why Regular Security Door Maintenance Matters

Security doors are constantly exposed to use, sunlight, temperature changes, and outdoor elements. Without proper care, small issues—like dry hinges or chipped paint—can turn into bigger problems.

Routine maintenance helps:

• Extend the life of your door

• Prevent premature wear on hinges and hardware

• Maintain smooth operation and proper latching

• Protect the door’s finish from damage and corrosion

1. Oil Hinges at Least Once Per Year

Hinges are one of the most important—and most overlooked—components of a security door.

Best practices for hinge maintenance:

• Oil hinges at least once per year

• Use a penetrating oil or spray lubricant

• Lubricate each bushing on all three hinges thoroughly

• Open and close the door several times to work the oil in

• Wipe away excess lubricant with a clean rag

This simple step helps prevent hinges from wearing out prematurely.
Do not use graphite lubricant on hinges, as it is not recommended for this application.

2. Clean the Door Finish the Right Way

Keeping your door clean helps protect the finish and prevent scratches.

Recommended cleaning method:

• Wipe the door with a soft, damp cloth when dirty

• Avoid harsh cleaners, abrasive tools, or power washers

• If water alone isn’t enough, use a car shampoo or cleaner safe for painted surfaces

Gentle cleaning preserves the finish and keeps your door looking its best.

3. Touch Up Paint Chips Immediately

Touch-up paint is typically provided at the time of installation. Keep it stored safely and use it as soon as chips occur.

Why this matters:

• Even small chips can compromise the finish

• Exposed metal can lead to corrosion

• Prompt touch-ups keep the door protected and looking new

Do not let small chips go unattended.

4. Protect Doors Exposed to Full Sun

If your security door receives full sun for much of the day, extra protection can significantly extend the life of the paint.

Helpful tip:

• Apply an automotive-grade polish such as Nu Finish, Armor All, or a similar product

• Thoroughly clean the door before applying

• Follow product instructions carefully

This adds a protective layer that helps shield the finish from UV damage.

5. Minimize Water Exposure

Excess water can negatively impact your door over time.

To reduce unnecessary moisture exposure:

• Avoid allowing sprinklers to soak the door

• Keep water from pooling near the frame

• Ensure proper drainage around the entryway

Keeping water off your door whenever possible helps preserve both the finish and hardware.

6. Prevent Chips and Scratches from Impact

Everyday habits can affect your door more than you realize.

Common causes of damage include:

• Keys striking the door while locking or unlocking

• Hard or sharp objects bumping into the surface

Being mindful during daily use can prevent many chips and scratches before they happen.

7. Adjust the Door Closer as Needed

Door closers are affected by:

• Temperature changes

• Seasonal pressure differences

• Running air conditioning or heating

• Glass panel configurations

It’s completely normal for your door to require adjustments throughout the year—sometimes more than once.

How to adjust the closer:

• Use a screwdriver

• Locate the screw on the end of the closer cylinder

• Turn the screw slightly to adjust the air release rate

• Test the door and continue adjusting gradually until it closes and latches properly

Small adjustments make a big difference in performance.
