AfterSensor Calibration Services in Westminster, CO
Sensor calibration in Westminster typically costs $95 to $165, depending on whether the issue stems from simple bracket misalignment, wiring damage, or a need for replacement of the photo-eye units. At Servo Garage Doors Westminster, we view these safety sensors as the most critical component of your garage door system, and we prioritize their function above all else. If your garage door is reversing unexpectedly or the status light on your motor unit is flashing, call us at (720) 807-1427 for a prompt, documented assessment.
We provide professional Garage Door Repair in Westminster that focuses on evidence-based solutions. Whether you live near the trails at Standley Lake or in the established neighborhoods of Hyland Greens, your garage door system faces specific challenges. Colorado’s temperature fluctuations cause expansion and contraction in concrete foundations and metal tracks, which can shift sensor alignment over time. We understand these local variables and provide a specific, written scope of work before we touch a single tool, adhering to Clause 1 of The Haven Standard.
When You Need Sensor Calibration
Garage door sensors, also known as photo-eyes, are designed to stop the door from closing if an object, pet, or person interrupts the invisible infrared beam. When these sensors lose their calibration, the system defaults to a safety mode, preventing the door from closing entirely. You should call us for a professional inspection if you notice any of the following:
- The door reverses immediately: You press the button to close the door, and it starts to descend but immediately reverses back to the open position, often accompanied by the motor unit light flashing ten times.
- Inconsistent closing: The door closes successfully on sunny days but fails when the sun hits the sensors directly, indicating an issue with the sensor sensitivity or shielding that requires professional adjustment.
- Physical damage to the housing: A bicycle, trash can, or car bumper has bumped the sensor, bending the bracket or cracking the plastic housing that protects the internal electronics.
- Intermittent signal loss: The door works sometimes but fails at other times, which often points to a loose wire connection at the logic board or a frayed wire running along the track.
- Signs of corrosion: If you see rust or oxidation on the sensor brackets or the wire terminals, the electrical connection is likely degrading, which causes the signal to drop intermittently.
If you are experiencing these issues, do not attempt to bypass the sensors by taping them together or overriding the system. These sensors are a mandatory safety feature. If you have any questions about how your specific system is behaving, you can always return to our home page to see our full range of services or call our team directly for clarification.
Our Sensor Calibration Process
When we arrive at your Westminster home, we do not guess at the problem. We follow a systematic procedure to identify the failure point, ensuring you know exactly what is wrong before we perform any work. This is the foundation of our Garage Door Repair service.
- Visual Inspection and Testing: We begin by visually inspecting the alignment of both the sending and receiving eyes. We use a level to ensure the brackets are plumb and that the infrared beam is unobstructed.
- Electrical Continuity Check: We test the wiring from the sensors back to the motor unit. If the wires are frayed or broken, we identify the exact location of the damage.
- Photo Documentation (Clause 4): As per Clause 4 of The Haven Standard, we photograph the failed component-whether it is a misaligned bracket or a damaged wire-and show you the evidence. You see exactly why the calibration failed before we offer a solution.
- Adjustment or Component Replacement: If the sensors are functional but misaligned, we adjust the brackets and secure them. If the sensors are faulty, we replace them with high-quality components compatible with your specific opener, whether it is a LiftMaster, Chamberlain, or Genie system.
- Safety Verification: We perform a final obstruction test to ensure the door reverses immediately when the beam is broken. We verify that the safety reversal system is fully operational and meets the manufacturer’s safety specifications.
- Final Documentation: We provide you with a written record of the work performed, ensuring you have a clear history of the repair for your home maintenance records.

AfterSensor Calibration Pricing in Westminster
Transparency is the core of our business model. We do not hide our pricing behind a “call for a quote” wall. We provide flat, written prices before work begins. The following ranges represent the typical costs for sensor-related services in the Westminster area, based on the scope of the repair needed.
| Service Type | Estimated Price Range |
|---|---|
| Standard Sensor Alignment & Bracket Adjustment | $95 - $125 |
| Wiring Repair (Splice, Re-termination, or Wire Pathing) | $130 - $165 |
| Photo-Eye Sensor Unit Replacement | $150 - $220 |
Every estimate we provide is flat and includes labor and materials. If we find that the issue is not the sensors but the logic board or the motor unit itself, we will show you the photo evidence and provide a separate, written quote for that specific repair before proceeding. We also offer a Free Second Opinion on any written estimate you have received from another company. If you have paperwork from a competitor, bring it to us, and we will verify the findings against our own inspection.
Safety and Professional Standards
We must emphasize that garage door sensors are safety devices. High-tension garage door springs, Spring Repair, cables, and electrical components involve significant risks. Never attempt to rewire a logic board or modify the safety sensors yourself. If you are uncertain about the state of your system, or if your door is failing to reverse when the beam is broken, stop using the door immediately and call a professional. Working with electrical components in a garage environment requires specific knowledge of low-voltage circuitry. Our technicians are background-checked and uniformed, and they operate under the strict guidelines of The Haven Standard to ensure that every repair is performed correctly and safely.
FAQs - Sensor Calibration
Why does my garage door close, but then suddenly reverse?
The most common cause for a door reversing is that the infrared beam between the two sensors has been interrupted or the sensors have lost their alignment. If the beam is blocked by an object, or if the sensors are vibrating due to a loose bracket or need Track Realignment, the system interprets this as an obstruction and reverses the door to prevent entrapment.
Can I fix a misaligned sensor by myself?
While you can check if a broom or box is blocking the beam, we advise against attempting to adjust the brackets or rewire the sensors yourself. These components are part of a safety system that, if improperly installed, can lead to the door failing to reverse when it should. If you have cleared the area and the door still reverses, call (720) 807-1427 for a professional adjustment.
Do you service all brands of garage door openers?
Yes. Our team is experienced with all major brands, including LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. Because we are independently owned and operated under The Haven Standard, we focus on the mechanics of the system rather than the brand name, ensuring we can calibrate or replace sensors on almost any residential opener.
What happens if the sensor replacement does not fix the problem?
Our 365-Day Done Right Promise covers our work. If a repair we perform does not resolve the issue, we make it right. We also provide a full photo record of the findings, so you know exactly what was replaced and why. If the sensors were not the root cause, our initial inspection would have identified the secondary issue-such as a logic board failure-before we performed any work.
If you are experiencing issues with your garage door sensors in Westminster, do not wait for the problem to escalate into a larger repair requiring our Garage Door Repair services. We provide honest, evidence-based service to ensure your system is safe and reliable. Call (720) 807-1427 today to schedule your service. Estimates are free, and we are ready to help you get your garage door back in working order.
