How to maintain your
garage door springs

A garage door spring stores enough energy to launch the entire door upward in seconds. That's exactly what it's supposed to do — and it's also why a worn or unbalanced spring is so dangerous. Most homeowners never think about their springs until one snaps.

At Nova Millennium, we replace springs every single week across Maryland, Virginia, and Washington DC. Almost every one we replace could have been caught months earlier. Here's what every homeowner should know about keeping springs healthy — and when to step back and call someone trained to handle them.

Tip No. 01Inspect Springs Regularly

You don't need to be a technician to spot a spring in trouble. Most failures give warning signs weeks or even months in advance — visible if you actually look for them.

Check your springs every few months for:

• Rust — orange or brown discoloration, especially around the coil gaps. A rusted spring is a brittle spring.
• Visible wear — flattening, polished spots where coils have rubbed.
• Stretching — gaps between coils that look different from when the spring was new.
• One spring looking different from the other — they should be twins.

Springs are designed for about 10,000 cycles — roughly 7 to 9 years on a typical residential door. If yours is approaching that age, inspect more carefully and plan for replacement before a failure forces the timing.

Tip No. 02Listen for Unusual Noises

Your ears will warn you before your eyes do. Spring problems make characteristic sounds — and a homeowner who knows them can catch a failure days or weeks before it happens.

Pay attention to:

• Squeaking as the door moves — often just needs lubrication, but a dry spring wears faster.
• Grinding — usually a coil rubbing against itself or the support shaft.
• A loud popping or banging sound — almost always a coil snapping. Stop using the door immediately.
• The opener straining on a door it used to lift smoothly — a sign the springs aren't carrying their share of the weight.

Tip No. 03Lubricate Springs

Lubrication is one of the few maintenance tasks homeowners can do safely on their own — and it's also one of the most effective for extending spring life.

The right way to do it:

• Use a silicone-based or lithium spray lubricant made for garage doors.
• Apply a thin, even coat across the entire coil.
• Wipe off any excess — you want a light film, not a dripping spring.
• Repeat every 3 to 4 months, or whenever the door starts sounding louder.

Avoid WD-40 entirely. It's a degreaser, not a lubricant — it strips away whatever protection is there and accelerates rust. A $12 can of proper garage door lubricant lasts years and protects a $300 spring set.

Tip No. 04Balance the Door

The balance test is the single most useful thing a homeowner can do to assess spring health. It takes thirty seconds and tells you exactly what shape your springs are in.

How to test:

• Close the door fully.
• Pull the red emergency release cord to disconnect from the opener.
• Manually lift the door to about waist height and let go.

A door with healthy springs stays exactly where you let it. If it sags downward, springs are losing tension. If it rises on its own, they're over-tensioned. Either way, the springs need professional adjustment — and the longer you wait, the more strain on the opener.

Tip No. 05Call a Professional for Repairs

Inspection and lubrication are homeowner jobs. Adjustment, tensioning, and replacement are not. Garage door springs hold up to 400 pounds of tension — enough to break a wrist, blind an eye, or worse. There is no DIY scenario where the savings are worth the risk.

Bring in a professional when:

• The balance test fails (door doesn't stay where you let it).
• You see rust, stretching, or gaps in the coil.
• You hear popping or banging during operation.
• The door has been around 8 years or longer.
• You don't remember the last time anyone looked at it.

At Nova Millennium, our certified technicians replace springs in matched pairs using premium parts — never one spring at a time, never with mismatched specs. It's a one-hour job for a trained tech, and it should always end with a fully tested, balanced door.

In ShortSprings Reward Attention

A garage door spring that gets a 30-second visual check every few months and a fresh coat of lubricant twice a year will routinely last longer than its rated lifespan. A spring that gets none of that fails early, loudly, and usually at the worst possible moment.

The math is simple. A few minutes of attention extends the life of a $300 part by years. When the time does come to replace, call a professional. It's the one part of your garage door system where DIY isn't worth saving the labor cost.
