Common causes of breakage to canopy garage doors

    There are many common things that will cause damage to the mechanism on most canopy garage doors, and these few things (if followed), will prevent likely damage and improve the life span of your canopy garage door also.


    It is important to lubricate your garage door at approximately 2-3 month intervals (some don't see a drop of oil in 20-25 years!) . By lubricating the door, you are obviously reducing the friction on the door, which in turn makes it operate easier. The type of oil we use is WD40 , as it is a light oil type which will evaporate after around 2-3 months, without leaving any mess, using heavier oils such as '3 in 1' can make the garage door work okay initially, but as time goes on, grit and dirt will stick to the thicker oil, and as more and more grit and dirt adheres to the oil, it ends up as a Black mess which can turn hard, we have in the past had to chisel this off!

    Use of Grease of any kind on a garage door should ONLY be used on lock contact points, and sparingly if you do have to use grease.

    To lubricate a canopy garage door, the places to ideally lubricate are the Spring, any pivot points, shaft bushes and of course the rollers and the guides. Some guide channels are only accesible when the garage door is open (ie CD45 geared doors), whereas on Henderson garage doors, the guide is visible with the door closed. Obviously, lubrication needs to be undertaken from inside the garage, as the spring is best oiled from the inside, which will save a lot of oil dripping down onto your garage door.

    Using the door

    This may sound like you are being taught to suck eggs ..... But

    Operate your canopy garage door from the centre! As some driveways are quite short, people tend to park close to their garage door, which then makes it impossible to stand between the car and garage door, and in turn, the garage door is then pulled down from one corner or the other, when you look at how most canopy garage door work, it is simply a continuous shaft with a cable and cone assembly either end, and the cables are of equal length, if for some reason the door snags because it is not being pulled down evenly, a cable can jump off, causing the door to go up at an angle within the opening. This will result in 95% of cases, the need for a replacement set of cables/cables and cones.


    The tension on your garage door is important. Too little tension and the cables are likely to jump out of place or your door is likely to fall closed or be blown down by a slight gust of wind. Too much tension, and the door could fly open causing injury and at the same time, putting a lot of un-needed stress on the lifting gear/cables.

    Please do not attempt to adjust the tension on a garage door if you have not done it before, as there are great spring forces in place, and the likelihood of injury is great.

    I hope that this may help in some way to increase the life of your door.

    If you feel your door would 'appreciate' a service, please contact us, and we will do the rest for you.

    Regular servicing is advised by all manufacturers of garage doors, with the service interval periods usually ranging from 12-18 months, usually, we only hear once the door has gone wrong and parts have broken.

    Guarantees can also become void if servicing has not been undertaken from new, some manufacturers will ask for proof of your door being serviced by a reputable company before agreeing to undertake warranty work
