Safety sensor repair in Alpine, Utah
$125 to $300 is the Alpine price for real sensor work; most calls never get that far. Alignment drift and dirty lenses dominate the fault list — plus frost film in the cold months — and a cloth and a wing nut resolve them at no cost.

The free fix, first
Check the floor-level units first. A steady light on both means the beam survives; anything dark or flickering gets the free treatment — lenses wiped (in Alpine's cold months, frost film on the glass is a routine culprit), bracket loosened, sensor re-aimed until the light locks, wing nut retightened.
If the light still will not hold, the fault moves to wiring — stapled, chewed or pulled bell wire on the run back to the opener — and that is where the $125–$300 call earns itself.
Alpine against its neighbours
The measurements shift town by town: Highland's median home dates to 1998 (post-mandate stock); Cedar Hills's median home dates to 2002 (post-mandate stock); and American Fork's median home dates to 1990 (pre-mandate stock).
Against that backdrop, Alpine holds 100.1 cycles at 5,099 ft with a 1997 median build year — the specific inputs behind every figure above.

How much does garage door sensor repair cost in Alpine?
Real sensor or wiring work runs $125–$300 in Alpine — but wipe the lenses and re-aim the brackets first, because those free fixes close most sensor tickets before they open.
Can I bypass the sensors to make the door close?
Never. Defeating them removes the door's only automatic reversal, mandatory since 1993, and it converts a nuisance into a hazard. The door is telling you something specific — around Alpine it is most often a bracket out of aim or winter film on a lens.
