What a Garage Door Tune Up Actually Covers

Tune up is a loose phrase, used to sell anything from a ten minute spray down to a genuine mechanical inspection. The line items a real visit should include come from Orange County Garage Door Tune Up, CA ageducate, so a homeowner can tell the two apart before a garage door technician is standing in the driveway. The list is the same one that applies across Orange County whether the door is two years old or twenty.

The Balance Test

Everything else is downstream of this. With the opener disconnected the door should hold still at waist height and move under a light hand through its whole travel. A door that drops or rises on its own is out of balance, which means the torsion spring no longer matches the weight, and every other adjustment is then being made against a moving target.

Hardware Tightening

Every hinge, every bracket, the splices, the rear hanger and the opener mounting get checked with a spanner. Fasteners loosen from vibration and there are typically sixty of them on a sectional door. This is unglamorous, takes fifteen minutes, and prevents more faults than anything else on the visit.

Rollers, Cables and Rail

Each roller gets spun by hand and checked for play. The cable is drawn through a rag looking for broken strands and inspected where it wraps the drum. The track is checked for plumb, for spacing and for any bend, and its channel is wiped rather than oiled.

Safety Systems

The photo eye pair is checked for alignment and lens dirt, reversal on contact is tested with an obstruction on the floor, and the force setting is confirmed to be no higher than the door needs. A safety sensor that has been aimed past a stored bicycle is the single most common thing found on a first visit.

Lubrication

Hinge barrels, roller stems, the springs, the bearings and the opener rail, each with the right product and none of it in the channel of the rail. Lubrication is the part everybody knows about and it is perhaps a tenth of the value of the appointment.

What Gets Reported Rather Than Fixed

Spring cycle life, a bowed top section, a weather seal that has hardened, rust starting inside a rail. These are conditions rather than faults, and a good report tells you roughly how long you have. A visit that finds nothing at all on a ten year old door was not an inspection.
