Q: Why is my garage door motor squeaking?

(from Anthea K, Floreat)

A squeaking garage door is probably a sign that it is under strain – particularly if you have a heavy door. Alternatively, squeaking could be caused by your worm drive. The worm drive is the direct drive from your motor (usually found in motors that have been under strain for quite some time) or it could be lack of lubricant on the chain.


Q: My garage motor chain goes slack and then tight, what’s causing this?

(from Michael Gould, Mosman Park)

If your garage motor chain goes slack and then tight, it’s likely that there are issues with your gear drive – that’s the cog that turns your chain. This happens a lot on doors that haven’t been serviced regularly. The weight of the door pulls on the motor/chain and, as such, wears down the sprocket, so it no longer rotates 360 efficiently. This is what would cause the change in the chain movement. Therefore, regular servicing will fix this problem.


Q: My garage door cable is frayed on one side only; do I need to replace them both?

(from Steven Smithson, Hamilton Hill)

Your cables maintain your door balance, so when you have a weakness in one side, the balance cannot be corrected. We always recommend replacing both cables; they are like shoelaces, and do the same amount of work as each other, so if one is on its way out, its only a matter of time until the other does the same.


Q: How do I take the light cover off my Guardian garage motor?

(from Adam Feldman, Mt Lawley)

These can be tricky; the knack is the press and pull away, the belt drive openers have a design so you know where to hold, the chain drive operators don’t have these ( which is where it can be tricky ) but it’s a central position whereby you need to release the small flap on the inside of the cover. Old motors that need light covers removed can be brittle, so we do keep a few spares on us incise this happens.


Q: The fixings in my door seem ‘loose’ for some reason, what would you recommend?

(from Maria Covic, Wanneroo)

If the fixings on your door seem loose for any reason, there are a few things you could try. You could try tightening the fixings, using a tech gun or spanners, or you could replace them. Quite often, garage door fixings can comprise of small tech screws and would benefit from being replaced by a larger -or at least be next size up fixing. That’s what we use at Guardian as standard but many new installations, especially with new build just get fixed with the small tech screws and these work their way out quite easily.


Q: My garage door is noisy when it opens and closes, can anything be done to quieten it?

(from Sharon Coombe, Hillarys)

A noisy door is usually a heavy door – you can help this by lubricating your door, check your hinges and rollers for their condition, check your door balance, if it is dropping at the halfway mark, it more than likely needs a service.


Q: Is there any way I can prevent my cables from jumping off? And why do they do that?

(from Steven Johnston, Palmyra)

Cables usually jump off due to lack of spring tension, or if your door has been impacted/brought down on something – like a car or bike or solid object – so you can sometimes prevent this nasty accident by making sure the garage spring tension is correct. When cables have come off due to impact, the only way to avoid this in future would be to install PE beams (photo beams) on the door.


Q: My rollers have popped out on one side of my garage door; is there anything I can do myself to fix this?

(from David Anderson, Rockingham)

If you’re rollers have popped out on one side of your garage door, you can try to fix the rollers yourself, but I would exercise caution. Fixing the rollers would involve bending or removing the track – and when done incorrectly, can cause the opposite side to pop out, leaving you with a bigger mess than what you started with. Professionally speaking, I recommend you call your service/repair technicians for any roller problems.

Oiling a garage door chain



Q: What’s the most important tool in your toolbox for garage door servicing and repairs?

from Tony Palimeno, Fremantle

My 10 ml spanner and tensioning bars are probably the most important tools for garage door servicing, the tension bars help me ensure the spring balance and tension is correct, and the spanners are needed to unlock the grub screws so we can apply the right amount of tension.


Q: What’s the best product for getting rid of rust on my garage door hinges?

from Eric Byrne, Claremont

If your hinges are rusted, they are likely weakened and worn.  Even if you clean the hinges and remove the raft, you can’t undo the damage to the product. The hinges hold your panels together, so they need to be in good condition. This is why we often replace a lot of rusted hinges. So no, there’s no ideal product to remove the rust from your hinges. Get them replaced, instead.


Forch garage door lubricantQ: What’s the best sort of grease to use on my garage door?

from Murray Chapman, Scarborough

For garage door springs, we use a lithium-based grease, as the spring coil is metal on metal, this helps prevent them from binding. For hinges and motor chains/rollers – I would say a light WD40 lubricant is best. You don’t want to be too heavy handed as excess lubricant can attract sand and dust, so just a light spray should do the trick.




Q: My garage door springs are making a creaking noise, what could be causing this?

from Dani Rattigan, Malaga

If your garage door springs are making a creaking noise, they could be binding (this is where the coils rub together), dry due to lack of lubrication, or they could be snaking. We use the word ‘snaking’ because instead of being aligned and straight, the springs tend to ‘snake’ or bend when they need tension/servicing.


Garage Door SpringsQ: How do I know when my garage door springs need replacing?

from Dariel Sommerville, Leeming

Your springs will likely snap before you know they need replacement. If you hear a loud bang when you’ve attempted to operate the door, that’s usually an indication that your springs have snapped. Of course, you can also find out if your springs need replacing if you’ve hired a professional serviceman who has told you that your springs are weak. (We identify this when applying tension – weak springs will not accommodate the right amount of tension as well as better-conditioned springs.)


Q: Can I DIY install garage door springs?

from Vanessa Overington, Dianella

Installing your own garage door springs is not recommended. There are so many accidents installing garage door springs every year – they are under a tremendous amount of pressure when fully adjusted and one small error or mistake can result in a very serious accident. As a professional garage door technician, I would never recommend a layperson doing this.



Q: Why do I need to service my garage door annually?

from Peter Grenfeld, Midland

Guardian-Doors-Perth-Residential-Service-VanGenerally, springs have around 700 – 800 turns until they start to wear off. Considering that most people use their garage a couple of times a day, that gives you around 10-12 months until your springs loosen. Annual servicing is based on the above approximation. Once the springs loosen, the door becomes heavy, and a heavy door is a dangerous door. I heavy door also puts a lot of pressure on your motor, because when the springs aren’t lifting 100% of the weight, the motor will pick up the slack.


Q: What happens if I don’t service my garage door?

from Michelle Caroll, Wembley

If you don’t service your garage door, you run the risk of a heavy door, loose fixings, wearing down your motor, hinges seizing, cables stretching, and spring snapping. Its like running a car with no oil. Not only is it about idea, but it is an expensive option – because when you decide to get help, you may find that it’s too late for servicing; you may have to purchase a brand-new door.



garage door remote controlQ: Is programming a remote control easy to DIY or do I need a technician to do this?

from Steve Whitfield, Waneroo

Yes, most remote controls are easily synced; the office has full programming instructions for all different makes and models. If a customer has problems, though, we also talk them through it over the phone.


Q: How do I replace my remote-control batteries?

from Anna Taylor, Scarborough

All our garage door techs have batteries on our vans, but if you are caught out, you can always take the small screws out of the back of the remote (or some remotes may have a clip close) and take it into your chosen supplier and get a new one. The wall remote you have in your garage is also battery operated. They are usually fixed to the wall with a screw; people think they are hard-wired, but they aren’t, and the batteries can be replaced in the same way as hand held remotes.


Q: Why does my remote only work when its close to the garage door?

from Stewart Sutcliffe, West Leederville

This could be an issue with your remote-control circuit board, it could be time to replace your batteries or it could be an issue with your garage door motor’s logic board. I always recommend changing the batteries first as this is usually the cheapest option.

Q: What’s the Guardian Workmanship warranty?

from Sarah Smith, Applecross

We offer 12 months workmanship that covers all different types of usage from your average house of 2-3 times a day garage door opening, through to the household that use it like a front door.


Q: What’s the warranty period for new motors?

from Leon Steinway, North Perth

Different brands carry different warranty period, so they generally range from 2-7 years. Ultimately, if you get your door serviced, not only will you keep your warranty, but you will have much less issues with your door.
