Signs your automatic door needs repair.
Automatic sliding doors have more moving parts than standard patio doors. Sensors, motors, controllers, belts, and safety systems all need to work together. When something fails, you'll usually notice one of these symptoms.
Door Won't Open When You Walk Up
The motion sensor isn't detecting movement. Could be a dead sensor, wiring issue, or power supply failure.
Opens Too Slowly or Too Fast
The speed controller is out of calibration. This affects traffic flow and can be a safety concern at busy entrances.
Opens by Itself (Phantom Openings)
Misaligned sensors picking up reflections, HVAC airflow, or movement outside the intended detection zone.
Grinding or Unusual Motor Noise
The motor bearings are wearing out, the belt is slipping, or the track has debris causing extra resistance.
Door Doesn't Close Completely
A track obstruction, misaligned limit switch, or faulty safety sensor is preventing the door from reaching the closed position.
Glass Is Cracked or Damaged
Impact damage, stress cracks from frame misalignment, or thermal expansion can crack automatic door glass panels.
Where we see automatic doors on the Treasure Coast
Automatic sliding doors aren't just for big-box stores. We service them at medical offices in Port St. Lucie, hotel lobbies in Stuart, restaurant entrances in Jensen Beach, retail shops, and even high-end homes that use them for accessibility or luxury convenience. If your door has a sensor and motor, we can fix it. Florida's humidity, salt air, and storm debris are hard on these systems, so regular maintenance and quick repairs are important.
If any of these sound familiar, don't wait. A malfunctioning automatic door is a safety and liability issue, especially for businesses that need ADA-compliant entrances. Call us at (772) 207-4146 and we'll get it diagnosed fast.
How we repair automatic sliding doors.
We've worked on automatic doors from every major manufacturer. Our process covers the full system, not just the part that's obviously broken.
Diagnose
We test the motion sensors, safety sensors, motor, controller, track, belt/chain drive, and power supply. Most automatic door problems have a root cause that isn't always the obvious symptom.
Identify
We pinpoint the failed component and source the right replacement part. We carry common sensors and controllers on the truck. Brand-specific parts from Besam, Dorma, and Stanley are available within 24 to 48 hours.
Repair
We swap sensors, adjust controllers, replace motors or belts, clean tracks, and repair wiring. Everything is done on site. We don't remove doors and take them to a shop.
Test
We run the door through 20+ open/close cycles, verify safety sensor response, check ADA timing requirements, and confirm the door holds position when obstructed. You'll see it working perfectly before we leave.
ADA compliance matters
Commercial automatic doors need to meet ADA standards for opening speed, hold-open time, and closing force. If your door closes too fast or doesn't stay open long enough, it's not just inconvenient, it's a compliance issue. We calibrate every automatic door we repair to meet or exceed ADA timing requirements. That protects your customers and your business. If you're not sure whether your door is compliant, we'll check it during any service call.
Automatic Door Repair Pricing
* Estimated labor costs. Parts and materials may be additional. We quote the exact price before starting.
Most automatic sliding door repairs fall between $200 and $800, depending on the component that needs work. New installations run $2,000 to $6,000 or more based on door size, operator brand, and sensor configuration. We always confirm the exact price before starting. No surprises. If you need glass replacement too, we'll quote that separately.

Whether your automatic door was made by a global manufacturer or a specialty builder, we've got the experience and parts access to fix it right.
Automatic doors for businesses and homes.
Automatic sliding doors work differently depending on where they're installed. Here's how commercial and residential systems compare.
Commercial Automatic Doors
- Heavy-duty motors built for thousands of cycles per day
- Overhead-mounted operators with belt or chain drives
- Wide detection zones for high foot traffic
- ADA-compliant timing and closing force required
- Safety sensors to prevent entrapment
- Common at storefronts, hospitals, hotels, and restaurants
Residential Automatic Doors
- Lighter-duty motors for lower daily use
- Concealed operators for a cleaner look
- Narrower detection zones to avoid false triggers
- Often installed for accessibility or mobility needs
- Wall-mounted or floor-mounted activation options
- Growing trend in luxury homes and aging-in-place remodels
We handle both. Whether it's a high-traffic commercial storefront door in Fort Pierce or a residential accessibility door in Vero Beach, we've got the parts and know-how to get it working again. Commercial doors usually need faster turnaround since a broken entrance can shut down your business, and we prioritize those calls.
Preventive maintenance keeps costs down
Automatic doors have a lot of moving parts that wear over time. We recommend servicing them every 6 to 12 months. A maintenance visit includes cleaning the track, testing all sensors, checking belt tension, lubricating the motor and rollers, and verifying the controller settings. This catches small problems before they become expensive breakdowns. Most maintenance visits cost $125 to $200, which is far less than an emergency motor replacement. Ask about our maintenance plans when you call.
Motor and controller diagnostics
When an automatic door stops working, the motor or controller is often the culprit. We use diagnostic tools to test motor amperage, controller output signals, and wiring continuity before replacing anything. This targeted approach means we fix the actual failed component instead of swapping parts until something works. Whether it's a burned-out motor winding, a faulty relay on the logic board, or a corroded connector from Florida's salt air, we'll find it and fix it on site.
