Garage Door Tune-Up and Safety Check in Plano

What a tune-up is actually for

A garage door is the heaviest moving object in the house and most people never think about it until it stops. The point of a yearly visit is to find the parts that are wearing while they are still parts rather than emergencies. A frayed cable is a $150 item on a Tuesday afternoon. The same cable snapping is a door on the ground, a bent section and a household with no way out of the garage.

Nothing about the visit is dramatic. It is forty five minutes of measuring, checking and tightening, with a written report at the end.

The balance test tells us the truth

Everything starts with the door disconnected from the opener and lifted by hand. A correctly balanced door feels like ten or fifteen pounds through the whole travel and stays where you put it at waist height. A door that wants to slam down has springs losing tension. A door that shoots up has too much. A door that feels heavy at the bottom and light at the top often has a cable winding unevenly on one drum.

That single test explains most complaints. Openers that struggle, doors that reverse for no reason and motors that die early are usually balance problems wearing a different costume.

The 25 points, grouped

Springs, shaft, bearings and drums. Cables at both ends and along their length. Rollers, hinges and end stiles. Track alignment, plumb and fixings. Bottom bracket condition. Bottom seal and side weatherstrip. Opener rail, trolley, chain or belt tension. Travel limits and force settings. Photo eye height, alignment and wiring. Auto-reverse against an obstruction. Emergency release cord and its height. Remote and keypad function. Anything scoring poorly gets photographed and written up with a price, and nothing gets replaced without you agreeing first.

Local wear patterns worth knowing

Heat is the quiet one. An attached garage in Plano sits well over 100 degrees inside for weeks each summer, and the lubricant that came on the rollers and bearings from the factory thins out and runs off. Doors here dry out faster than the same door would in a milder climate, which is the main reason an annual service pays for itself.

Dust and grit are next. North Texas soil finds its way into every bearing, and a roller running dry with grit in it wears both itself and the track.

Then there is the volume of doors. Almost every home out here has two or three garage bays, and one of them is the one everyone uses. That door might see three times the cycles of the one beside it while the springs on both were fitted on the same day. We check each door on its own merits rather than assuming they have aged together, and that is often where a surprise turns up.
