How often should you lubricate a garage door?

Short answer

Inspect and lubricate the garage door every 6 to 12 months. Spring and fall are the natural times, since cold stiffens everything and heat dries the old lubricant out. The job is a can of silicone or white lithium garage door lubricant on the hinges, rollers and springs, a look at every bolt and cable, and a balance test with the opener disconnected. It takes 20 to 30 minutes and the lubricant costs $5 to $15.

Why it matters

A garage door is the heaviest moving thing in the house, and it moves on a row of hinges, a set of rollers and a pair of springs that carry nearly all its weight. Those parts wear against each other every time the door goes up and down, and on most homes that's several times a day. Dry hinges squeal and wear oval. Dry rollers drag in the track and chip. A spring that isn't oiled rusts, and rust is what breaks springs.

The opener is the part that pays for all of it. An opener is sized to lift a balanced door, which weighs almost nothing in its hands when the springs are right. A door that's dragging, out of balance or sticking in the track makes the opener strain, and openers that strain burn out their gears and motors years early. A few minutes with a spray can keeps the door light, the opener relaxed, and the springs, which cost real money and can hurt someone when they break, in good shape.

When to do it more often

The index gives no modifiers, so the schedule holds. What changes within it is which end to pick:

A door that runs many times a day, in a house where the garage is the front door: the 6 month end.
A garage that faces the weather, where rain and road salt reach the track: the 6 month end.
A door that's started to squeak, judder or hesitate between services: now, since it's telling you.

What you need

A socket set, for the bolts that hold the hinges and the track brackets
Rags, to wipe the track and catch drips

Steps at a glance

Close the door, unplug the opener, and pull the release cord so the door is disconnected from it.
Lift the door by hand to about waist height and let go. A balanced door stays put. One that drops or rises needs a spring adjustment, which is a technician's job.
Go over every hinge, roller bracket and track bracket and snug any loose bolt.
Spray the hinges at their pivot points, the roller bearings, and the springs along their length, wiping away the excess.
Spray the opener's rail or chain lightly if the manual says to, and the lock and the bearings on the torsion bar.
Wipe the inside of the tracks clean with a rag, but don't lubricate them, since grease in the track collects grit.
Reconnect the opener and run the door up and down, listening for anything that still squeaks.

You're done when the door runs quietly, moves smoothly by hand, and holds its position at waist height with the opener disconnected.

Signs it's overdue

Squeaking or grinding as the door moves.
Jerky movement, or a shudder at a particular point in the travel.
Loose hardware you can see or hear rattling.
A door that's hard to lift by hand with the opener disconnected, which means the springs are losing tension.

DIY or pro

This is an easy job, and the spray can does most of it. The one rule is to leave the springs' tension alone. Lubricate them, look at them for rust and gaps, but don't adjust or unwind them. The balance test tells you whether they need a technician, and a technician is what they need.

A garage door tune-up runs $100 to $250 and covers the lubrication, the hardware, the balance, and an adjustment of the springs and the opener's force settings. If the balance test fails, if a cable is frayed, or if the door is older than its 10 to 30 year life and groaning, that's the call. A door company will also replace worn rollers, which turn a loud door quiet.

Safety

Structural: the springs hold the full weight of the door under tension, and a torsion spring that lets go while someone is working on it can break bones. Don't loosen, adjust or remove a spring, a cable or the brackets they attach to. Keep fingers out of the hinge gaps while the door moves, and keep the opener unplugged while you work.

FAQ

What should you use to lubricate a garage door?

A silicone or white lithium spray made for garage doors. Skip general-purpose penetrating oils, which thin the existing grease and attract dirt.

Which parts of a garage door should be lubricated?

Hinges, roller bearings, springs, the bearings on the torsion bar, and the lock. Not the tracks, which should be clean and dry.

Why is my garage door so loud?

Dry hinges and rollers are the usual cause, and lubrication fixes most of it. Worn steel rollers and loose hardware are next. A door that's still loud after lubricating needs a tune-up.

How do I know if my garage door springs are bad?

Disconnect the opener and lift the door halfway. If it won't stay put, the springs have lost tension. A gap in a torsion spring means it's broken. Both are jobs for a technician.
