Learn More About Garage Door Repairs And Some Tips To Do It Yourself

 

Single panel Garage doors are constructed from one monolithic panel. From the closed position a single panel garage door swings up and overhead with a hinge on each side (known as jamb type hardware) to the fully open position. A disadvantage of monolithic panel garage doors is that the swing up arc of the garage door occurs partially outside the garage. This means a vehicle must stop and park several feet in front of the garage door to avoid being hit by the garage door when it is opened.

Single panel garage doors can also be installed with (one piece track type hardware) that folds the garage door back with a single horizontal track on each side (which is mounted at the top of the wood frame) and a roller, (mounted to the top of the garage door on each side. A hinge on each side that attaches to the bottom of each side of garage door. Using track hardware, a car can be parked much closer to the garage door, as the whole door, when in the open position, rests completely inside of the garage door header. Track type hardware has much less arc when raising and lowering the garage door as opposed jamb type hardware

 

Sectional garage door panel being installed

Sectional garage doors are usually constructed of three to eight panels and slide up and overhead. Sectional doors occupy exactly the same amount of internal garage space as a monolithic door. Sectional garage doors have two advantages over single panel monolithic doors:

Sectional garage doors do not require any space outside the garage to open. A vehicle may park very close to the garage before opening the door.

Each panel of a sectional garage door has its own connection to the door track. This increases reliability and robustness compared to monolithic doors, which have only a few track connections for the whole panel.

Garage doors can be made out of many materials, but steel, aluminum, wood, copper, glass, and vinyl (polyethylene) are the most popular materials. Some manufacturers incorporate foamed-in-place polyurethane insulation within the monolithic panel and sectional garage doors.

Roller garage doors ("Sheet Doors"-USA) are usually constructed of corrugated steel. They evolved from cover window and door coverings.[4] Other materials can be used (e.g.; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door has a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung (except USA) and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.

In the UK (and other parts of the EU), 'insulated' roller garage doors are available, using an aluminium lathe filled with polyurethane foam for thermal and acoustic insulation.

In terms of thermal insulation, the roller door has a typical insulation value of 4.9 to 5.2. A sheet steel garage door has a typical insulation value of 6.1 to 6.4. Application that need more thermal insulation typically use foam filled sectional garage door, which provide typical insulation values of 2.7 to 1.3.

 

 

Garage door materials

Aluminum garage doors are low-cost, light, rust-proof, and feature low-maintenance. They are prone to denting because aluminum is not strong and they are energy-inefficient since aluminum is a highly conductive material.

Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.

Steel garage doors have become common and are available in a variety of sizes and styles, provide strength and security, are cost-competitive, and may have optional insulating value. Extra strength is available with two or three layers of galvanized steel with a low gauge number (23-24 gauge steel panels).

Wood garage doors offer aesthetic appeal, but they are high-maintenance and may be expensive. Low-priced wood garage doors may warp and break easily.

 

 

A common material for a new garage door is steel sheet formed or stamped to look like a raised panel wooden door. Steel doors are available in uninsulated, insulated, and double skin steel. A design mimicking carriage house garage  doors has become popular since early 2000s, and many manufacturers clad the exterior of a steel door with composite, vinyl boards, or other trim to give it the appearance of wood.

 

 

In situations involving residential attached garages where the insulating value and the energy efficiency of a garage door is important to prevent overheating and freezing problems, as well as for comfort and energy savings.

Some manufacturers advertise very high insulating values for some of their garage doors (R-15 to R-17), but it may be true for only for some central sections. The actual R-values – for the entire door – are often 1/2 or 1/3 of the advertised value

 

 

A torsion spring counterbalance system consists of one or two tightly wound up springs on a steel shaft with cable drums at both ends. The entire apparatus mounts on the header wall above the garage door and has three supports: a center bearing plate with a steel or nylon bearing and two end bearing plates at both ends. The springs themselves consist of the steel wire with a stationary cone at one end and a winding cone at the other end. The stationary cone is attached to the center bearing plate. The winding cone consists of holes every 90 degrees for winding the springs and two set screws to secure the springs to the shaft. Steel counterbalance cables run from the roller brackets at the bottom corners of the garage door to a notch in the cable drums. When the garage door is raised, the springs unwind and the stored tension lifts the garage door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension

 

 

Garage door manufacturers typically produce garage doors fitted with torsion springs that provide a minimum of 10,000 to 15,000 cycles and are guaranteed for three to seven years. One cycle is a single opening and closing sequence. Most manufacturers offer a 30,000 cycle spring. However, it is important to remember that if the weight of the garage door is increased by adding glass, additional insulation, or even several coats of paint, the life of the torsion spring may be greatly reduced. Additionally, springs at highly humid environments, such as coastal regions tend to have a significantly shorter cycle life, due to the corrosive cracking.

Other factors like poor garage door maintenance, loose tracks, or components shorten torsion spring life. Owners are advised to avoid applying grease to garage door tracks because that makes the wheels "skate" in the track instead of turning on their bearings. Only bearings, hinges, and spring wire require lubricant.

 

An extension spring counterbalance system consists of a pair of stretched springs running parallel to the horizontal tracks. The springs lift the door through a system of pulleys and counterbalance cables running from the bottom corner brackets through the pulleys. When the door is raised, the springs contract, thus lifting the door as the tension is released. Typically these springs are made of 11 gauge galvanized steel, and the lengths of these springs are based on the height of the garage door in question. Their lifting weight capacity can best be identified by the color that is painted on the ends of the springs.

 

 

There are five types of garage door openers:

Chain drive openers have a chain (similar to a bicycle's) that connects the trolley to the motor.

Belt drive openers use a rubber belt in place of a chain.

Screw drive openers have a long screw inside the track. The trolley connects to this screw.

Direct drive openers have the motor installed inside the trolley and use a gear wheel to guide the trolley along a fixed chain.

Jackshaft openers mount on the wall at either end of the torsion bar.

 

 

 

 

Safety

Garage doors cause injury and property damage (including expensive damage to the door itself) in several different ways. The most common causes of injury from garage door systems include falling doors, pinch points, improperly adjusted opener force settings and safety eyes, attempts at do-it-yourself repair without the proper knowledge or tools, and uncontrolled release of spring tension (on extension spring systems).

A garage door with a broken spring, or the wrong strength spring, can fall. Because the effective mass of the door increases as the garage door sections transfer from the horizontal to vertical door tracks, a falling garage door accelerates rapidly. A free falling garage door can cause serious injury or death.

The sections and rollers on garage doors represent a major pinch hazard. Children should never be allowed near a moving garage door for this reason. On manually operated garage doors, handles should be installed vertically, to promote "vertical orientation of the hand".

Mechanical garage door openers can pull or push a garage door with enough force to injure or kill people and pets if they become trapped. All modern openers are equipped with “force settings” that make the door reverse if it encounters too much resistance while closing or opening. Any garage door opener sold in the United States after 1992 requires safety eyes—sensors that prevent the door from closing if obstructed. Force settings should cause a door to stop or reverse on encountering more than approximately 20 lbs (9.07 kg) of resistance. Safety eyes should be installed a maximum of six inches above the ground. Many garage door injuries, and nearly all garage door related property damage, can be avoided by following these precautions.

Certain parts, especially springs, cables, bottom brackets, and spring anchor plates, are under extreme tension. Injuries can occur if parts under tension are removed.

Extension spring systems should always be restrained by a safety cable that runs through the middle of the spring, tying off to a solid point at the rear and front of the horizontal garage door track. Extension springs represent a hazard to bystanders when a spring, pulley, or cable breaks under tension. Metal parts from extension spring systems can suddenly be launched.

 

 

 

Testing old and new doors

In older houses, the garage door may be original or a replacement. Not sure of its vintage? You might be able to track the door's manufacturing date through a model type listed in the owner's manual. If not, conduct this series of tests in order to discover if the door does not have a reversing feature or is a modern model with the feature in need of repair.

• Balance. To check balance, start with the garage door closed and trip the release mechanism so you can maneuver the door by hand. If the door is balanced (properly spring-loaded and running freely on its tracks), you should be able to lift the garage door smoothly without much effort and it should stay open about three or four feet above the floor.

If the garage door flies up or down when you let go, the balance needs adjusting. Because the springs store so much power, you should have their tension corrected by a qualified service contractor.

• Force setting. Test the force setting of the opener by holding the bottom of the door as it closes. If the garage door does not reverse as you apply moderate resistance, the setting is probably excessive. (Consult your owner's manual for specific details about adjusting the setting.)

• Reversing test. Place a 2-by-4 block on the flat in the path of the garage door. If it does not promptly reverse on hitting the block, you should repair a modern opener or replace an older one that lacks the reversing feature.

Basic maintenance

The humdrum part is basic maintenance, mainly cleaning, oiling and a shot of graphite in the lock. Many manufacturers recommend cleaning the tracks and then applying a light machine oil, except to plastic parts.

One of the largest garage door makers, Liftmaster, says to oil door rollers, bearings and hinges monthly, using a silicone lubricant or light oil.

There are some fixes any homeowner with a level and socket wrench can take on, such as aligning the tracks. Though door wheels have some leeway, if the tracks are not parallel and plumb, the wheels can drag and also wear out prematurely.

The solution is to loosen the bolts in the track mounts just enough so you can realign the tracks before retightening.

 

 

Safer garage doors

There are two main ways to make automatic garage doors safer. The first and most obvious is to install a modern system that meets current standards.

Since January 1993, the Consumer Product Safety Commission has required that all garage door openers have what's called an external entrapment protection system. In practical application this translates to an electric eye (or similar system) aligned with the opening and mounted four to six inches off the floor. These will reverse the door before it hits anything detected by the sensors in the door's path.

Many older systems reverse only after contact (sometimes quite a collision) or don't reverse automatically under any circumstances. If your garage door is more than 10 years old, consider upgrading, says the CPSC, and replace pre-1982 openers that do not reverse.

The CPSC offers this strong recommendation because the auto-reversing feature has significantly reduced personal injury and property damage -- so much so that in 2001 the standard was extended to include automatic security gates that are increasingly common at the entrances of apartment and condo communities.

The second basic safeguard is to test your door periodically (the CPSC suggests a somewhat rigorous, once-a month schedule) and perform regular maintenance and repairs as needed. Although basic guidelines apply to all automatic openers, check your owner's manual or contact the opener manufacturer about specific (and sometimes different) procedures.

Most of the safety guidance is aimed at parents of young children; No. 1 on the list compiled by door manufacturers, the CPSC and the National Safety Council, is not to let kids play "beat the door." Backing up a sensible step, the groups also advise parents not to let children play with or use garage-door remote controls.

As a further precaution, you should mount the keypad wall control out of children's reach -- at least five feet from the floor -- and in a location where users can clearly see the moving door.

In case all else fails and someone is pinned by the door, it's also important to know how to use the emergency release. Generally, you simply pull down on the short rope hanging from the operator motor. This feature, a standard since 1982, disconnects the opener system from the door so you can lift it by hand.
