Our service technicians arrive at your door equipped to tackle even the most difficult jobs. After a thorough inspection, our service technician will explain the problem to you and the measures/parts required to remedy the problem. If there are multiple ways to fix the problem, the technician will explain each in detail and advise you of the best. At the conclusion of the job, our technician will supply you with an invoice. Payment can be made via cash, cheque, credit card, direct deposit or eftpos.

99% of the time, we are able to repair the problem on the day, or replace the unit altogether, which in some cases, turns out to be cheaper and more worthwhile than the repair on the day, or cheaper in the long haul (other parts may be creeping closer to the “expiration” date). On the rare occasion that the repair cannot by carried out on the same day, it is usually because you may require extra materials such as jambs, custom panel springs or simply because the job requires 2 technicians instead of 1. However, in these cases our technician will relay the information straight to us and we will be able to supply you with the time and date of our next visit before our technician leaves your premises.

We can also set up a “Preventative Maintenance Schedule” to ensure that your door/gate and opener run as optimally as possible and to significantly minimize the likelihood and inconvenience of a breakdown.  With the “Preventative Maintenance Schedule” it allows our technician to keep a watchful eye over things like your door tension, motor parameters, and to maintain lubricated gears and hinges. It also means our technician will detect parts that may be “on the way out” before they cause problems, and if desired replace the required parts on the day instead of suffering a secondary service call when it decides to give way.

Garage Door Springs

Your garage door is the biggest moving object in your house, and as you would expect, they can be extremely heavy and dangerous. Be that as it may, most of this weight is counter-balanced by your garage door springs.

All garage doors have springs; some you can see (panel doors & tilt doors) and some you can’t see (roller doors). This is why a well-tensioned garage door can be manually operated with ease; because the springs do almost all of the lifting.

Garage door springs have been engineered to take most of the load of your door. When your tension is low or your spring breaks, it can be crippling, sometimes literally. Trying to lift a garage door, which can weigh up to 150kgs, without the assistance of springs can cause serious personal injury, and should only ever be attempted by a trained technician.

Garage door springs are available in 2 different types;

• Extension type springs. These springs can be seen on tilt doors. They are found on the side of  the door fixed to a set of power arms. There are various type of extension springs, but the concept is the same; when the door is closed, the springs are fully extended.
• Tortion type springs. These springs can be seen on panel doors. They are found on the tortion bar, which is located above the top panel on a front-mount panel door, or at the rear of the horizontal tracks on a rear-mount panel door. These springs exert power by twisting.

There are several signs that can point to a broken spring. These include:

1. The physical appearance (refer to broken panel spring picture under “Garage Door Repairs”)
2. The opener straining to open the door, and in some cases stopping altogether on the way up. You may also find that it closes with a loud thud.
3. The door is too heavy to lift in manual operation.
4. The panel & tilt door opener is running but the chain is not moving.
5. The tilt door pulls to one side, and may jam on the side of the opening when attempting to operate the door.

If, upon inspection, you find that your spring is broken, cease using the door immediately, both by opener and by hand, even if it still opens automatically. Continuing to use the opener with a broken spring, even though it may work, will significantly increase the load on the motor and may cause it to burn out, greatly inflating repair costs.

Here at AGG Doors, springs are replaced in sets. This is more a pre-cautionary measure. When your first spring breaks, all the load is thrust on the remaining spring, applying significantly more tension then the spring is use to and greatly weakening the steel coil. Once your broken spring is replaced, the surviving spring (in its weakened state) has to work as efficient as the new spring, and in an effort to keep up, breaks in the process.

In conclusion, there is only one rule when your spring breaks; stop using the door.

Below is a checklist for relevant information when enquiring about broken garage door springs, ranging with the most important to the least.

• Panel Doors (torsion type springs):

1. The size of the door, ie - 2250mm h x 4880mm w.
2. Brand of the door, ie - B&D, CSI, Steel-Line.
3. Length of the spring, not including the end cap and anchor plate. Always measure the 2 halves of the broken spring and then add together. Springs stretch when they are tensioned, and the good spring will still have tention on it, therefore measuring the good spring will not help us gauge what spring you may require .
4. The length of 10 coils.
5. The inside and outside diameter of the broken spring.

6. The diameter of the wire (should equal length of 10 coils divided by 10).
7. The amount of panels that make up your door, and how many of them have an aluminium bracing running across it (on double panel doors there are usually support braces on the top and bottom panels at the least).

• Tilt Doors (extension type springs):

1. The length of the broken spring, not including the hooks on each end.
2. Whether the tilt door has tracks and rollers in the top corners of the door. If they do, the length of the power-arm and the distance between the 2 pivot points on the power-arm.
3. The amount of springs on each side.
4. The size of the door, ie - 2250mm h x 4880mm w.

• Roller Doors

We do not replace the springs on roller doors.
