What Is Preventative Maintenance?

Many homeowners think about servicing their garage door only after something has broken. Unfortunately, by the time a spring snaps, a motor starts struggling, or the door refuses to open, what could have been a small repair has often turned into a much larger and more expensive one.

At Planet Automation, one of the questions we’re often asked is, “What exactly is preventative maintenance?”

The answer is simple.

Preventative maintenance is about identifying and repairing small issues before they become major problems. It’s a proactive approach that helps reduce repair costs, extends the lifespan of your garage door, and prevents unexpected breakdowns that could leave your home vulnerable or inaccessible.

Why Preventative Maintenance Matters

Your garage door is one of the largest moving parts in your home.

For many families, it isn’t just where they park their car—it’s the main entrance to the house. Every time the door opens and closes, the springs, rollers, hinges, bearings, cables and motor all work together to lift a significant amount of weight.

Like any mechanical system, these components wear over time.

Regular servicing allows these wear items to be identified and replaced before they fail, helping you avoid expensive emergency repairs and unnecessary downtime.

A Real Example from Our Experience

One example that stands out involved a customer whose garage door we installed in 2022.

Since the installation, the garage door became the family’s primary entrance and exit, meaning it was used far more frequently than an average residential door.

Unfortunately, the customer never had the door serviced.

Instead, they waited until components failed before calling us.

By the time we inspected the system, several major repairs were required because multiple components had worn beyond their normal service life.

Had the door been serviced regularly, many of those repairs could have been identified early and addressed while they were still relatively inexpensive.

This is something we see regularly.

Reactive repairs almost always cost more than preventative maintenance.

What Happens During a Preventative Maintenance Service?

Many people assume a garage door service simply involves applying lubricant.

In reality, a professional preventative maintenance visit is a comprehensive inspection of the entire system.

At Planet Automation, we typically inspect and service:

• Garage door springs.
• Lift cables.
• Rollers.
• Hinges.
• Bearings.
• Tracks.
• Door balance.
• Garage door motor operation.
• Motor limits and force settings where applicable.
• Safety features.
• General hardware and fasteners.
• Lubrication of appropriate moving components.

Our goal is to identify components that are beginning to wear before they become a problem.

What Happens If You Skip Maintenance?

One of the biggest misconceptions is that if the garage door is still opening, everything must be fine.

Unfortunately, that’s rarely the case.

When maintenance is neglected, we commonly see failures involving:

• Springs.
• Rollers.
• Hinges.
• Bearings.
• Cables.
• Worn hardware.
• Garage door motors.

One failing component often places additional strain on another.

For example, if the springs lose tension, the garage door motor has to work much harder to lift the door. Over time, this unnecessary strain can significantly shorten the lifespan of the motor, turning what could have been a relatively small repair into a much larger expense.

Preventative maintenance helps stop that chain reaction before it starts.

How Often Should a Garage Door Be Serviced?

There is no single servicing schedule that suits every garage door.

The correct maintenance interval depends largely on how often the door is used.

As a general recommendation:

• Standard residential garage doors should be professionally serviced at least once a year.
• Garage doors used more than 15 times per day are considered high usage and should be serviced at least every six months.

High-use doors experience far greater wear, making regular inspections even more important.

Treat Your Garage Door Like Your Car

One of the best ways to think about preventative maintenance is to compare your garage door to your vehicle.

Most people wouldn’t drive their car for years without changing the oil or having it serviced. They understand that regular maintenance helps prevent expensive mechanical failures later.

Your garage door deserves the same attention.

It’s a mechanical system with moving parts that operate every single day. Ignoring it until something breaks almost always results in higher repair costs than simply maintaining it properly.

If there’s one thing we’ve learned after years of repairing and servicing garage doors across Cape Town, it’s this:

Don’t wait until something breaks.

Small issues are far easier, and far less expensive to repair than major failures.

Regular preventative maintenance not only extends the life of your garage door but also protects your garage door motor, improves safety and helps ensure your home remains secure.

Investing in routine servicing is one of the smartest decisions a homeowner can make. Like servicing your car, it’s not an unnecessary expense. It’s an investment in reliability, safety and long-term savings.
