Garage Door Tune-Up in Roches Point

On most openers a steady light on each photo-eye means the pair are aligned and seeing each other, and a blinking light means the beam is interrupted or the sensors are out of line. Common causes are a bracket nudged by a bin or a tire, dust or salt film on a lens, low sun at a certain hour, or a chafed wire. During a tune-up the lenses are cleaned, the brackets straightened, the pair realigned and the wiring checked back to the opener.

A silicone-based or white lithium garage door lubricant, sold for the purpose. Penetrating oils and general sprays are thin, attract dust and are gone in weeks; heavy grease traps grit. For the rubber bottom seal and weatherstrip, use only a silicone spray, since petroleum products attack rubber and make it brittle. Nylon rollers with sealed bearings need no lubricant, while ones with an exposed bearing can need a touch where their own maker calls for it. A small amount on each point, worked in by moving the door, is enough.

For a single or double residential door with an opener, allow roughly an hour to two hours on site. The inspection and the two observed cycles take a fixed amount of time; the rest depends on how many fasteners have loosened, whether the sensors need realigning and whether you approve a small part replacement, such as a worn roller, during the same visit. Spring or cable work, if found necessary, is scheduled as its own job.
