I'm going to do the rant first because it's the part everybody needs.
WD-40 is not a lubricant.
Not the kind a hinge needs, anyway. Look at the name: WD stands for Water Displacement, 40th formulation. It was developed in 1953 to keep rust off Atlas missiles. It's mostly solvent carrying a thin penetrating oil, so it washes the existing grease out of your hinges, the solvent evaporates, and what's left is a film too thin to do much for long.
The reason every Reddit thread, every Facebook neighbourhood group, and every father-in-law in Coquitlam swears by WD-40 for garage doors is that it does, briefly, make a squeaky hinge quiet. For about a week. Then the solvent's gone, the hinge attracts dust, the dust mixes with what's left of the carrier fluid, and you've got a sticky paste that's worse than nothing. Then you spray more WD-40. Then it gets worse. Then you call me.
I am not mad at WD-40. WD-40 is fantastic at what it actually does: cleaning rust, freeing seized fasteners, displacing moisture out of electrical connections that got rained on. It is a tool. It is not the tool for moving hinges. Use it to clean. Don't use it to lubricate. End of rant. We can be friends.
Use white lithium grease. Or silicone spray.
White lithium grease comes in a $9 spray can at Canadian Tire, Home Depot, or any auto parts store. The spray is all you need — the brush-on tub is overkill for a house. Silicone spray (Permatex, CRC Heavy Duty) is the second-best option and arguably the better choice if you live near salt water — Madison runs it on most Tsawwassen homes.
Why these and not WD-40, motor oil, or 3-in-One:
- White lithium grease — thick, stays put, doesn't drip onto your car. Good operating range -20°C to 150°C, which covers anything Burnaby Mountain throws at it. Won't wash off in an atmospheric river.
- Silicone spray — slipperier than grease, better for rollers and weatherstripping, doesn't attract dust. Reapply twice a year instead of once.
- Motor oil — too thin, drips everywhere, attracts grit. No.
- 3-in-One — actually a decent light oil, fine for the keyed lock cylinder, too light for hinges.
The 5-minute routine — four points, twice a year
Do it once in spring and once in fall: May, as the rainy season winds down, and October, as it gets going. The easy way to remember is the Victoria Day long weekend and the Thanksgiving long weekend. Or just set a calendar reminder.
1. Hinges (between every panel)
One short squirt where the hinge pin meets the bracket on each panel joint. There are usually 3 to 5 hinges per side. Don't drown it — a one-second spray is plenty.
2. Rollers (the wheels in the track)
One squirt where the roller stem enters the bearing. Not the wheel itself — the bearing inside the roller. If you have nylon rollers (white wheel, quieter), use silicone and keep the grease off the nylon wheel itself.
3. Spring coils (the big horizontal one above the door)
Light coat along the length of the spring. This is corrosion prevention, not motion lubrication — the coils don't slide, they twist against each other. The grease keeps moisture off the metal and stops the spring from singing in cold weather. Do not stick your hands in the spring area. Spray from a safe arm's length.
4. The shaft bearings (ends of the torsion shaft)
The bearing plates at the top corners above the door, where the shaft passes through — one squirt each, plus one on the centre bearing between the springs if you can reach it without getting near the spring. These bearings carry the shaft and the cable drums, which means the whole weight of the door. They deserve the attention.
What to skip
- The track itself. The track is not a lubrication surface. The rollers ride in it. A greasy track collects grit and turns into sandpaper. Wipe it clean with a rag, don't lube it.
- The opener chain or screw drive. Follow the opener manual — some want nothing, some want a specific grease. If the opener itself is squealing, that's an opener question, not a spring one, and it's not something we work on.
- The photo-eye sensors. Never. Soft cloth, water only, no chemicals near those lenses. (Madison wrote a whole piece on that for fog season.)
- The weatherstripping. Silicone is fine. Lithium grease will stain rubber. Skip if in doubt.
Why this matters more on the Lower Mainland than most places
We live in a temperate rainforest that pretends, for marketing purposes, to be a city. Lynn Valley gets well over 2,000 mm of rain a year. New Westminster gets around 1,500. Even "dry" Tsawwassen still gets a solid 900-plus. Every fall, when an atmospheric river — sorry, the Pineapple Express — parks over us for days at a time, every exposed steel hinge and roller bearing in your garage gets a daily dose of humidity. The grease is what stands between the metal and the moisture.
Small bonus: a door that moves freely makes the opener work less on every cycle. I am not promising you'll notice it on your BC Hydro bill. I am saying friction never did your door any favours.
The honest version
The reason this article exists is that I have seen too many spring jobs that didn't need to happen yet. In my experience, a twice-a-year lube routine buys an oil-tempered spring an extra couple of years. That's a $400-ish saving over the life of the door, for $9 worth of grease and ten minutes of your weekend. Grease is cheap, springs aren't. And if yours has already gone, call — the closest tech is usually 12 to 18 minutes out.
