More about this in San Leon
A broken garage door sensor keeps the door from closing at all, or lets it start down and then reverse straight back up before it ever reaches the floor. Either way the opener is reading the sensors as blocked or disconnected, whether or not anything is actually in the way.

Call (346) 220-4724 and a crew working the San Leon area will sort out which sensor is at fault and get the door closing again.
Why a broken garage door sensor stops the door from closing
The two sensors mounted low on either side of the garage door track have to see each other in a straight, unbroken line for the opener to let the door finish its trip down. Knock one out of alignment, crack a lens, or corrode a wire connection, and the opener treats the door as blocked even when the floor in front of it is completely clear. That's the difference between a real obstruction and a broken garage door sensor — the fix is entirely different depending on which one it is.
A broken garage door sensor after water sits in the garage
San Leon's average elevation is just 3 feet, with parts of the CDP running as low as 3 feet below sea level, so there's very little natural buffer between a garage floor here and the surrounding bay and tidal water. Sensor wiring and brackets mounted a few inches off a slab that's taken on water don't fail right away — corrosion works on the connections over time, and a sensor that tested fine last season can start throwing false readings the next. The write-up on broken garage door opener San Leon repair covers a fault that often gets mistaken for this one.
San Leon's flood risk makes garage door sensor wiring worth a second look
Effective August 15, 2019, Galveston County Commissioners Court approved revised FEMA floodplain maps that put the vast majority of San Leon into a high flood-risk category. That's not a general coastal-county label — it's a specific designation for this community, and it's directly relevant to any garage door sensor mounted low on a wall here, since those are exactly the components sitting closest to where floodwater would enter first.
What a broken garage door sensor call in San Leon usually turns out to be
San Leon received extensive damage from Hurricane Ike back in September 2008, and the San Leon Post Office was damaged in that storm and never replaced — a concrete example of how lasting some of the structural damage from surge has been here. Garages that took water in Ike or any storm since are more likely to have sensor wiring or brackets that have slowly corroded rather than a sensor that simply drifted out of alignment. With roughly 2,600 single-family homes in the CDP as of 2019, a good share of those sensor calls trace back to hardware that's been sitting near tidal water for years.
A broken garage door sensor is rarely something to force past by holding the wall button down, since that just masks the reading instead of fixing it.
