When an electric gate stops working in Dobbs Ferry, it’s rarely just a dead motor. The Hudson River salt air, steep rocky lots, and older stone pillars all work against gate hardware years before you’d expect trouble inland. Calder Gate Repair handles all of it: gate motor repair, opener repair, keypad and remote failures, safety sensors, and control boards. We’re the dedicated Electric Gate Repair team within the Relay Home Co. family, and our crews know the specific ways gates fail here. Call (585) 496-2148 and a live person answers, 24/7. We’ll give you a written price before any work starts.
Why Calder Gate Repair Yonkers Is Dobbs Ferry’s Preferred Electric Gate Repair Company
Dobbs Ferry homeowners call us because we answer the phone. Not a voicemail, not a bot. A real person who can book a trackable arrival window, same day when the job calls for it. Every technician arrives background-checked and in uniform, with a live arrival time you can follow from your phone.
We also know this terrain. Streets like Clinton Avenue, Walgrove Avenue, and the hillside lots off Cedar Street have gates that sag, bind, and corrode in ways a flat suburban gate never will. Nico Alvarez leads our team, and his crews have re-set hinge posts into Hudson River gneiss, rewelded hand-forged scrollwork, and replaced salt-eaten control boards inside enclosures that looked fine from the outside. That local knowledge gets the fix right the first time.
Every job carries the 365-Day Done Right Promise: if the repair fails within a year, we return free of charge. Written guarantee, every job. Written price, before any work starts. No exceptions.

Commercial Gate Operator in Dobbs Ferry
A Commercial Gate Operator in Dobbs Ferry means a heavier-duty unit built for more cycles per day than a residential swing or slide gate, and it’s what many estate homeowners here end up needing when a long, heavy custom gate overwhelms a standard opener. We see it often on the wider driveway entrances off Broadway and along the steeper side streets where gates are longer and heavier than typical suburban installs. When a residential opener strains on a 600-pound steel gate, the motor burns out early, the control board overheats, and repair becomes a recurring cost. Upgrading or properly matching a commercial-grade operator to the actual gate weight and cycle load stops that cycle.
Most commercial gate operator replacements in Dobbs Ferry run $2,200 – $4,800 depending on the gate’s weight, width, and whether we’re reusing existing safety loops and keypads. Board-only repairs run $380 – $750. Written quote before any work. Always.
Why Some Dobbs Ferry Gates Need a Heavier Operator
Wide, custom steel gates on stone pillars weigh far more than the manufacturer’s typical residential spec. Add wind load from a winter nor’easter and the opener works harder than it was built to. We size operators by gate weight, width, and duty cycle, not by the old unit’s horsepower rating. That’s the difference between a five-year opener and a fifteen-year opener here.
What a Commercial Operator Retrofit Involves
We mount the new operator to a reinforced post or pad, run the necessary power, install UL 325-compliant photoeyes and reversing edges, and program the travel limits and force settings. On rocky Dobbs Ferry lots, we often anchor the operator plate with epoxy-set bolts into ledge rather than a standard wedge anchor into shallow soil. The work is measured, ordered where needed, and scheduled with a written price before anything starts.
Automatic Gate Repair in Dobbs Ferry
Automatic Gate Repair in Dobbs Ferry usually starts with a phone call that goes something like: “the gate opens halfway and stops” or “the keypad works but the remote doesn’t.” From there we troubleshoot the system in order: power, operator motor, control board, safety sensors, and remote or keypad signal. Most automatic gate repairs in Dobbs Ferry run $240 – $620 before any harder-to-find parts. A full operator replacement with labor and programming typically lands between $1,600 and $3,800 depending on the gate type and brand.
We service LiftMaster, FAAC, Elite, and Mighty Mule units among others, and we stock common boards, remotes, and sensor parts for fast turnaround in Dobbs Ferry. You’ll get a written estimate before we touch a bolt.
When an Automatic Gate Needs a Control Board, Not a Motor
Homeowners often assume the motor died. But on the river side of Dobbs Ferry, we frequently open the control box and find a corroded board with green fuzz on the relay terminals. Salt air gets inside enclosures that are not gasketed properly, and the board fails before the motor does. We test board inputs and outputs first. If the board’s fine and the motor hums but doesn’t turn, then it’s a capacitor or a seized gearbox. We replace only what’s actually failed.
Keypads, Remotes, and Safety Sensors
Remotes and keypads are the most common point of failure after salt and cold weather. We reprogram, re-pair, and when needed replace keypads with weatherproof models that survive Hudson River winters. Safety sensors, the photoeyes near the bottom of the gate, get dirty, knocked out of alignment by snow plows, or chewed by rodents. We clean, realign, or replace them and verify the gate reverses properly before we leave.
Trusted Brands We Service in Dobbs Ferry
We’re factory-familiar with LiftMaster, FAAC, Elite, and Mighty Mule, which covers the majority of gate openers in Dobbs Ferry homes. Because we see these units constantly, we know which boards fail after salt exposure on the river side, which remotes lose pairing in cold snaps, and which models are worth repairing versus replacing. We keep common parts staged for fast Dobbs Ferry dispatch, and we can order rare components with direct dealer access. If your gate has a brand label we didn’t name, call anyway: we service nine major opener brands, and if we can’t fix it, we’ll tell you straight and point you to someone who can.

AfterCommon Electric Gate Repair Problems We See in Dobbs Ferry Homes
- Corroded hinge pins and post brackets. Galvanized hardware lasts 3 – 5 years in the salt air along the river. We replace with stainless fixings and marine-grade hardware when we rebuild, because anything less rusts again.
- Froze-and-cracked stone pillars. Freeze-thaw cycles crack the mortar around hinge posts, letting wide swing gates lean and bind. We reset posts with epoxy-set rock pins into the gneiss below, then re-point the masonry.
- Snow plow damage to slide gates. A plow edge clips the bottom track or knocks the loop detector out of tune, and the gate freezes mid-cycle. Pre-season track inspection and loop testing catch most of this early.
- Operator boards killed by salt air. The board inside the control box corrodes even when the enclosure looks clean outside. We swap in conformal-coated boards and seal the enclosure properly so it survives the river climate.

FAQs About Electric Gate Repair in Dobbs Ferry
The short answer: standard concrete footings often fail here. Dobbs Ferry sits on fractured Hudson River gneiss, and many hinge posts are set into shallow soil over bedrock. Soil creep on the slopes slowly pushes posts out of plumb, the gate sags, and the opener strains. We set post footings with rock pins or helical ties drilled into ledge, not just a bag of concrete, so the post stays where it belongs long after the repair truck leaves. Call (585) 496-2148 if your gate is dragging or leaning.
Yes, faster than you’d think. In Dobbs Ferry, we see operator circuit boards fail within 4 – 7 years from salt corrosion even when the enclosure looks sealed. The fix is a conformal-coated board and a properly gasketed enclosure rated for the environment, plus occasional inspection of the terminal connections. If your gate works intermittently after storms or damp weeks, the board is likely the culprit. We’ll test it before recommending replacement. Call (585) 496-2148 for a diagnosis.
Once a year, before first snow. A pre-season inspection catches bent tracks, out-of-tune loop detectors, and rusted rollers before a plow clip or a freeze-up makes the gate fail mid-cycle in January. If a plow has already hit the gate, we can usually straighten or replace the track section and re-tune the loop the same visit. Call (585) 496-2148 to book a pre-winter check before the first storm.
Yes, and we do it regularly. Dobbs Ferry has old wrought-iron gates on Walgrove Avenue, Clinton Avenue, and elsewhere with hand-forged hinges and scrollwork that no catalog sells. Our welders replicate the original hinge patterns rather than swapping in generic parts, and we match the patina. The gate stays original, the hardware stays functional, and the neighborhood character stays intact. Call (585) 496-2148 and we’ll come look at the hinge work up close.
UL 325 requires automatic gates to have two independent entrapment protection devices: typically photoeyes across the gate opening plus a reversing edge or contact sensor on the leading edge. This matters in Dobbs Ferry because wide, heavy gates on slopes can drift when posts shift, and a gate that drifts is a gate that could pin someone or something. We test the sensors under load, verify the reversing function, and bring every gate we service up to UL 325 before we finish. Call (585) 496-2148 to have your gate’s safety systems checked.
