AfterSensor Calibration in Marietta, GA
Garage door sensor calibration in Marietta typically costs $85 – $165 and most jobs are completed in under an hour. If your door reverses before closing, blinks a warning light, or refuses to close at all, the photo-eye sensors near the bottom of the track are likely misaligned or sending a weak signal. Marlow Garage Door Repair Marietta handles sensor calibration as part of our broader Garage Door Repair in Marietta work, and we’ll give you a written price before any wrench turns.
Photo-eye sensors sit about six inches off the ground on either side of your garage door opening. They shoot an invisible infrared beam across the doorway. When that beam is interrupted (by a bike tire, a trash can, or a child’s toy), the door stops and reverses. When the sensors drift out of alignment, the beam never connects, and your door acts like something is always in the way. Calibration is the process of realigning the lenses, cleaning them, checking the wiring, and confirming the signal strength is steady.
We’ve been doing this work across Marietta since 2002. Jaylen Ross leads our team, and every tech who walks up your driveway is background-checked and uniformed. You’ll see exactly who’s coming before they arrive. Call us at (912) 575-7540 any time, day or night, and a live person answers. No voicemail, no callback queue.
When You Need Sensor Calibration
Sensor problems don’t announce themselves with a bang like a broken Spring Repair does. They show up as small, annoying behaviors that get worse over a few weeks. Here’s what homeowners around Marietta call us about most often:
- The door reverses right after touching the floor. This is the most common symptom. The sensors see something that isn’t there, or the beam cuts out the moment the door settles.
- The opener light flashes but nothing moves. On Chamberlain and Genie openers, a blinking light often points at the safety sensors rather than the motor.
- You have to hold the wall button down to close the door. When the sensor circuit fails entirely, many openers only work in “constant pressure” mode, which is a stopgap, not a fix.
- One sensor has a steady light and the other is dim or off. Misalignment or a pinched wire. We see the latter a lot in older East Cobb homes where garage settling has shifted the track slightly.
- The door closes fine during the day but acts up at night. Sunlight hitting one photo-eye can wash out the infrared beam. West-facing garages near Marietta Square get hit hard in the late afternoon.
- You’ve bumped a sensor with a car, lawn mower, or storage bin. It doesn’t take much force to knock a bracket out of line, and once it’s off by a few degrees, the door won’t close normally.
If any of these sound familiar, calibration is usually the fix. Sometimes it’s a wiring issue or a failing sensor that needs replacement, and we’ll tell you which one before quoting anything.
Our Sensor Calibration Process
We keep this straightforward. You’ll know what’s happening at each step, and you’ll see the written price before we begin. Here’s how it goes:
- We test the door’s current behavior. We run the door through a full open and close cycle and watch how it responds. We check the opener’s diagnostic lights, which vary by brand, and confirm whether the issue is alignment, wiring, or the sensors themselves.
- We inspect both photo-eye units and their brackets. Loose brackets are the culprit more often than the sensors themselves, especially in Marietta garages where humidity and temperature swings cause the door track to expand and contract.
- We clean both lenses and realign the beam. Dust, spider webs, and pollen build up fast in Georgia. We wipe the lenses clean, then adjust each sensor until the receiving unit locks onto the beam with a solid indicator light.
- We check wire connections and signal strength. Loose staple clips or rodent-chewed wiring can weaken the signal even when lenses look perfectly aligned. We test continuity and secure every connection.
- We run the door through multiple full cycles. Open, close, reverse test, obstruction test. We make sure the door stops and reverses when something blocks the beam, and closes smoothly when the path is clear.
- You get a written price, we do the work, and the 365-Day Done Right Promise applies. If the sensors drift out of alignment again within a year, we come back and make it right at no charge. That’s in writing, not buried in fine print.
Every job includes The Relay Visibility Guarantee: a live arrival time you can track, before-and-after photos, a written price, and a digital invoice you pay from a link. You won’t sit in a four-hour window wondering if anyone is coming.
Sensor Calibration Pricing in Marietta
We believe in naming prices instead of hiding them behind vague “call for quote” language. Here’s what sensor calibration runs in Marietta as of this year:
- Basic sensor alignment and cleaning: $85 – $125. This covers realigning both photo-eyes, cleaning lenses, tightening brackets, and testing the full safety reverse cycle.
- Sensor alignment with wiring repair: $125 – $165. If a wire is pinched, corroded, or chewed through, we strip it back, splice in a new section with weatherproof connectors, and retest the circuit.
- Single sensor replacement (if calibration isn’t enough): $95 – $145 per unit. Some sensors simply fail, especially on older Genie and Chamberlain units that have been in service for 12-plus years.
- Full sensor replacement set with recalibration: $160 – $240. We use manufacturer-compatible units matched to your opener brand, and we test everything before we leave.
What affects the price? Mostly the age of your opener, whether wiring needs attention, and how much the Track Realignment has shifted out of square. In older Marietta neighborhoods like Whitlock and Maple Avenue, we see a lot of settled garage floors that make sensor alignment more finicky. That’s normal, and it’s factored into the quote you see before we start.
Every price is locked in writing before we touch a single bolt. If the number changes mid-job for any reason we didn’t anticipate, we stop, explain, and get your approval first. That’s not a policy we bend on.

FAQs – Sensor Calibration
How much does garage door sensor calibration cost in Marietta?
Sensor calibration in Marietta typically runs $85 – $165, depending on whether Cable Repair or wiring repair is needed and how far the track has drifted out of alignment. You’ll receive a written price before any work begins, and estimates are always free. Call (912) 575-7540 for an exact quote.
Can you calibrate my garage door sensors the same day?
Yes. Most sensor calibration jobs in Marietta are completed the same day you call, and the work itself usually takes under an hour. We’ll give you a live arrival window you can track, so you’re not guessing when we’ll show up.
Why does my garage door keep reversing when nothing is in the way?
A door that reverses right after closing usually has photo-eye sensors that are misaligned or dirty. In Marietta, afternoon sun can also wash out the infrared beam on west-facing garages, which causes the door to reverse randomly. A quick calibration fixes most cases.
Can I recalibrate the sensors myself?
You can wipe the lenses clean and check for obvious obstructions, but if the brackets have shifted or the wiring is compromised, alignment gets tricky. The photo-eyes are part of a safety system that prevents the door from closing on people and pets, so getting them right matters. If you’d rather have a trained eye on it, call (912) 575-7540 and we’ll handle it same day.
Is sensor calibration covered under the 365-Day Done Right Promise?
Yes. If your sensors drift out of alignment again within a full year of our repair, we come back and fix it at no charge. The promise is in writing on every job, and it applies to sensor calibration just like any other our Garage Door Repair services in Marietta.
