How Often Do Garage Door Springs Need Replacing?

Garage door springs are one of the hardest-working components of your entire garage door system, yet they’re also one of the most overlooked. Many homeowners only think about their springs once they’ve snapped, leaving them with a garage door that won’t open and an unexpected repair bill.

One of the questions we get asked regularly at Planet Automation is, “How often do garage door springs need replacing?”

The honest answer is that there isn’t a one size fits all timeframe. In our experience servicing garage doors throughout Cape Town, the lifespan of a spring depends on several important factors, and understanding them can help you avoid costly breakdowns.

What Determines How Long Garage Door Springs Last?

Garage door springs don’t simply wear out because they’ve reached a certain age. Their lifespan depends on a combination of factors, including:

• The quality of the springs installed.
• Whether the springs were correctly sized for the weight of the garage door.
• How often the garage door is opened and closed each day.
• Whether the garage door receives regular professional servicing.
• Environmental conditions, particularly in coastal areas.
• The overall condition of the garage door and its hardware.

A high quality spring that’s correctly installed and maintained can last many years. On the other hand, a poorly matched or neglected spring can fail much sooner than expected.

Why Coastal Homes Need Extra Attention

Living close to the ocean has many advantages, but it can be particularly harsh on garage door components.

One example that stands out involved a client in Melkbosstrand. We had installed new tension springs on their garage door, but within just two years, the springs had become heavily corroded and eventually snapped.

After inspecting the installation, we found two contributing factors:

• The garage door had no side seals, allowing salty coastal air to reach the hardware continuously.
• The door had not been professionally serviced as recommended.

The homeowner only contacted us once the springs had already failed. Rather than following a preventative maintenance plan, repairs were only carried out when something broke.

This is something we see regularly. Preventative maintenance almost always costs less than emergency repairs and significantly extends the life of your garage door.

Warning Signs Your Garage Door Springs Are Wearing Out

Garage door springs rarely fail without giving some warning.

Over the years, we’ve found homeowners often notice subtle changes before a spring finally breaks.

For sectional garage doors, listen for:

• A slight snapping or cracking sound during operation.
• The garage door becoming noisier than usual.
• The motor appearing to work harder than normal.

For tip-up garage doors:

• The door no longer stays open by itself when operated manually.
• The door feels noticeably heavier than it used to.

Other warning signs include:

• Visible rust on the springs.
• Springs that appear stretched or uneven.
• The garage door lifting unevenly.
• The motor struggling to lift the door.
• Jerky or inconsistent movement.

If you notice any of these symptoms, it’s best to have the system inspected before the springs fail completely.

Common Mistakes Homeowners Make

After years of repairing garage doors across Cape Town, we’ve noticed the same mistakes happen repeatedly.

Waiting Until the Springs Snap

Many homeowners ignore the warning signs and continue using the garage door until the springs eventually fail.

Unfortunately, this often places additional strain on the garage door motor, cables, rollers and other hardware, increasing the overall repair cost.

Trying to Replace Springs Yourself

Garage door springs are under extremely high tension.

Attempting to remove or replace them without the correct tools and training can result in serious injury or damage to the garage door.

Spring replacement is always a job that should be left to trained professionals.

Replacing Only One Spring

One of the biggest mistakes we see is replacing only the broken spring.

Garage door springs work as a pair. If one has reached the end of its lifespan, the second spring is usually not far behind.

Replacing both springs together ensures:

• Balanced operation.
• Reduced strain on the motor.
• Longer component life.
• Fewer future call-outs.

For this reason, we always recommend replacing springs in pairs.

Skipping Annual Maintenance

Regular servicing allows us to monitor the condition of the springs before they become a problem.

Waiting until something breaks almost always leads to more expensive repairs.

When Should Garage Door Springs Be Replaced?

Rather than replacing springs based purely on age, we recommend having them professionally inspected during your annual garage door service.

During a service, we assess:

• Spring wear.
• Tension levels.
• Signs of corrosion.
• Balance of the garage door.
• Overall condition of the lifting system.

This allows us to estimate how much useful life the springs still have and advise whether replacement should be planned before they become a safety risk.

Our Professional Advice

If there’s one piece of advice we give every homeowner, it’s this:

Don’t leave garage door springs until the last minute.

Regular servicing allows small problems to be identified long before they become expensive failures.

If your home is close to the ocean, preventative maintenance becomes even more important, as coastal conditions can dramatically shorten the lifespan of metal components.

Replacing springs proactively, always replacing them in pairs, and servicing your garage door annually will not only improve reliability but also protect your garage door motor and the rest of the system.

At Planet Automation, we’ve seen firsthand how preventative maintenance saves our customers money while keeping their garage doors operating safely for years to come. Sometimes, the cheapest repair is the one you never have to make.
