Torsion Springs


Springs carry garage doors that weigh hundreds of pounds. Without the assistance of the springs, neither you nor the opener could lift the door. An opener is only designed to lift up to 20 pounds, or about 10% of the weight of a door. With a balanced set of springs the door should be “Weightless” and operate with two finger pressure. A balanced set of springs should allow the door to sit at rest in equilibrium at any point you desire.

Springs wear out long before they snap. Like rubber bands springs lose their strength over time and continued use. At about its half-life the spring weakens to a point where undue weight is imposed on the opener and the door openers begin to fail and/or wears out. Weakened spring induced failures are specific exclusions from any opener warranty.

When springs break they do so with a huge bang that can be heard throughout the house. Garage door springs are coiled with hundreds of pounds of force. When the spring snaps it usually stays on the pipe that it is wrapped around, but sometimes the spring comes loose and becomes a dangerous projectile, severely damaging whatever it hits. More typically this happens with extension springs but it can happen with torsion springs as well.

Why springs break:

Age & Use. Springs usually die of old age. They wear out with time and use. Springs are in their fully coiled and tightened position when the garage door is closed….. which is almost all of its life. This is why springs age even when they are not being used. A normal door cycles open and closed 5 times a day or 1,800 cycles each year.

Low cycle springs. Builders install the cheapest possible doors and springs. These springs are not designed for long lives. They are designed to last between 3-5 years or about 5,000 – 10,000 cycles.


High cycle springs. A couple of spring manufacturers offer high cycle springs designed to last 10 years and up….. or between 30,000 – 50,000 cycles. These are the only springs we install.


Rust. In the coastal salt air environments surface rust can take its toll on steel. Our powder coated springs retain their rust resistance much longer than traditional oiled springs or galvanized springs.

Improper sizing. Quite often repair/replacement installers put in springs that are not properly sized for the door. This can dramatically shorten the life of a spring and the opener. This usually happens because the repair tech doesn’t carry all the sizes on his truck and compensates with too many or too few winds on the spring…… a temporary and destructive solution at best.

Replacing only one spring. When only one spring is replaced, the new spring does all the lifting. . One new spring will quickly wear out under the load. This voids the spring warranty because the system is designed to have two springs evenly sharing the weight of the door

All of our service trucks carry springs to suit your needs.


Cables & Drums


Aircraft Quality Cables. As with all our parts we use superior cables for our garage door repairs. We use aircraft cables for our garage door repairs. These are the cables that are used for aircraft steering and controls and as such are the finest cables available…… many grades higher than standard garage door cables. We do not charge extra for these cables even though they are more costly for us. We simply do this because providing superior quality is what we do.

Commercial grade drums. Our drums are larger and stronger, designed to withstand the loads imposed by far heavier commercial garage doors. Our drums have wider grooves allowing the cables to feed onto the drum more evenly with reduced tendency to create the sharp ridge that cuts and chafes into the cables.

All of our service trucks carry cables and drums to suit your needs.

Bearings


All bearings can wear out with age and use. Any bearing can seize or bind under the huge loads imposed by the springs and weight of the garage door. The bearings are under constant pressure from the springs while the door is closed.

The Center Bearing seems to be the first to go. Both springs exert all their force right next to the center bearing. Many door manufacturers installed plastic center bearings to save money. Unfortunately this plastic bearing bushing wears away and allows the torsion bar that carries the springs to distort and bend as the door cycles open and closed. The springs distort and chafe with the bending allowed by the worn plastic center bearing. The torsion bar that holds the springs in place can weaken and even break with continual bending allowed by a worn center bearing. When a torsion bar breaks it can become a dangerous missile. A torsion bar is quite flimsy without the support of the center bearing.

End bearings wear out when the center bearing allows too much bend or when there is misalignment of the bearings with the torsion bar.

All of our service trucks are fully stocked with bearings to suit your needs.

Rollers


Hurricane safety When hurricane force winds hit a garage door the door will bow inwards and outwards under the extreme pressure loads of the wind. A modest 120 MPH hurricane could exert enough force to bow the door in and out 6” at the center of the door or about a 5% bend for a double door. This is enough to pull the door right off normal length 3” rollers stems. This is why we install 4” and 7” stem rollers. We don’t want the door to run out of stem that holds the door to the track when it is flexing under the force of the winds.

Roller Quietness Rollers are the primary moving parts of a garage door. Many older doors have solid metal rollers that clank and bang and can be heard throughout the house as the door opens and closes. Our rollers have 13 sealed ball bearings which allows the rollers to turn freely while the stems remain stationary inside the hinges.. Our rollers also have nylon coated wheels. Together these bearings create a noise free door.

Reduced Friction Our 13 sealed ball bearings allow the stems to sit stationary in the hinge tubes while the rollers turn freely in the track. The difference in the friction and wear and tear is tremendous. The ease and smoothness of the door’s glide path is amazing.

Zero Maintenance. Our sealed 13 ball bearings require no lubrication and since the stems don’t rotate in the hinges there is no lubrication required at the stems either.

All of our service trucks carry all of our roller types for your convenience.
