Fast, Reliable Gate Motor & Opener Across Selden
A gate motor repair in Selden typically costs $220-$460, and if the operator itself needs replacing, a full motor swap with installation usually runs $700-$1,250 depending on the gate’s size and whether your existing posts are still sound. Most Selden calls we take get answered by a live person the second you dial, and we can usually have someone out to your property within 24-48 hours. Hal Gatewood has been working on Long Island gates since 2001, and the name on the shop is the same name on the invoice. Call (877) 610-2993 and you’ll get an honest read before we ever touch the gate.
Selden isn’t a town of brand-new subdivisions. It’s a place of 1960s ranches, 1970s split-levels, and backyard pools that have been there since Nixon was in office. That means gates hung decades ago, operators bolted on as afterthoughts, and posts that heave every time the ground freezes. We know what that looks like because we’ve fixed it on hundreds of Selden properties. Our Gate Motor & Opener team works across 11784 and every street off Middle Country Road, from College Road over to Boyle Road.
Why Gatewood Fence & Gate Is Selden’s Preferred Gate Motor & Opener Company
Hal started this company in 2001 because he was tired of seeing gates that other people had walked away from. A motor bolted to a sagging post. A control board sloppily spliced. Safety sensors that worked for a week and then quit. When we say we repair what others want to replace, that isn’t a slogan. It’s the actual way we work. If your operator can be saved, we’ll save it. If welding a bracket in place costs you $90 and a new motor costs $700, we’ll tell you that straight.
Every job we do in Selden carries the 90-Day Done Right Promise in writing. If it’s not done right, one call brings Hal back. That’s not a warranty buried in an email footer. It’s stamped on every invoice. And when you call (877) 610-2993, a live person picks up. Around the clock. Not a voicemail tree, not a call center in another state. Someone who can actually talk to you about your gate.
We’re certified to service nine major gate operator brands, and our crew shows up in uniform, background-checked, and ready to work. But more than that, we’re local to this part of Suffolk County. We don’t have to Google where Selden is. We’ve driven Boyle Road too many times to count.
Our Gate Motor & Opener Services in Selden
Motor Installation
Installing a new operator on an old Selden gate is where shortcuts show up fast. The motor is only as good as the post holding it. On 1960s and 1970s properties across 11784, we regularly find hinge posts that have heaved out of plumb after forty winters of freeze-thaw cycles in sandy glacial soil. We check the post, the hinge alignment, and the gate’s travel before we ever suggest a new motor. If the post needs resetting, we reset it. Then we mount the operator so the gate runs smooth the day we leave and still runs smooth in July.
A new operator installation in Selden includes mounting, wiring, limit switch setup, safety photocell installation, and a full walk-through of how the remote and keypad work. You get a written price before we start, and if we find something wrong during the job, you know about it before the cost changes. Most Selden motor installations run $300-$800 in labor, with the operator itself adding another $400-$900 depending on the brand and gate weight.

Motor Repair
Not every dead gate needs a new motor. On a Rustic Road split-level last spring, the operator was fine. The post wasn’t. The homeowner had a 1970s swing gate fitted with a LiftMaster a decade ago, but the hinge post had disintegrated in the sandy soil. The motor was fighting a sagging panel, and the safety photocell was misaligned because the whole geometry had shifted. We reset the post in new concrete, corrected the sag, and reinstalled the operator with a properly aimed photo-eye. Cost: a fraction of a full replacement. Result: a pool gate that actually passed the Town of Brookhaven self-latching check.
Motor repair in Selden covers capacitor replacement, limit switch adjustment, gear replacement, control board diagnosis, and wiring repairs. If the board is just loose or the capacitor is swollen, we fix it. If the board is fried and the part is obsolete, we tell you that too, and we walk you through what replacement actually costs before we spend another dollar of your money.

Linear Motor
Linear motors are common on the sliding driveway gates you see on bigger Selden lots, especially the ones along Adirondack Drive and the wider parcels near Whispering Pines. They’re solid units when they’re installed right. When they fail, it’s usually the drive chain, the travel stops, or the circuit board. We service Linear operators across Selden and keep repair parts on hand so we’re not ordering from across the country and making you wait two weeks to get your driveway back.
If your Linear motor is grinding, stopping mid-travel, or reversing for no reason, don’t keep forcing it. Every forced cycle strains the gears and makes a simple repair into a full replacement. Call us and we’ll diagnose it honestly.

Slide Motor
Slide gate operators handle serious weight, and on Selden properties with long driveways off Route 25, they get heavy use every single day. The motor itself is often fine while the real problem is the track, the wheels, or the chain tension. We inspect the whole run, not just the motor housing. A gate that drags because the track is packed with sand and debris will burn through a new motor in a year if you don’t fix the track first.
Slide motor service in Selden covers chain tensioning, track cleaning and alignment, wheel bearing inspection, limit switch adjustment, and motor replacement when it’s genuinely needed. If your gate shudders or slows halfway through the cycle, call before it strands your car on the wrong side.

Trusted Brands We Service in Selden
We work on FAAC, BFT, Linear, and Viking operators, along with LiftMaster, Mighty Mule, Ghost Controls, DoorKing, and Elite. Brand-specific repair knowledge matters. A BFT hydraulic operator fails differently than a Viking linear drive, and the diagnostic path isn’t the same. We keep common repair parts in our service vehicles so most Selden motor repairs don’t require a second trip just to fetch a capacitor. If your operator is one we can’t honestly fix, we’ll tell you, and we’ll help you pick a replacement that actually fits your gate instead of whatever happens to be on sale.
Common Gate Motor & Opener Problems We See in Selden Homes
- Dead control boards on legacy operators. Many Selden homes still run operators installed in the 1990s, and the control boards in those units are now obsolete. You can’t get the part from the manufacturer, and a used board off eBay is a gamble that usually ends in failure. When the board is gone, the honest answer is usually a new operator.
- Posts heaving from winter frost. Selden sits inland, away from the worst salt air, but the freeze-thaw cycle is brutal on gate posts. Sandy glacial outwash soil drains fast but anchors poorly. Posts shift a quarter inch every winter, and by March the gate doesn’t latch and the motor stalls mid-cycle.
- Safety photocells tripping constantly in spring. When a hinge post heaves, the gate panel shifts, and the photocells that were aligned in October are no longer aimed at each other. The motor refuses to move or reverses for no reason. It’s not the motor. It’s the geometry.
- Pool gates with no modern entrapment protection. A lot of original Selden pool gates were hung before UL 325 safety standards existed. The operator may have been added later, but it often lacks photo-eyes or edge sensors. When we’re called for a motor repair, we frequently find an operator running without the required safety devices. Under Town of Brookhaven code, that gate isn’t legal for pool use until the compliance issue is addressed.

FAQs - Gate Motor & Opener in Selden
If the board is still manufactured, yes, we can replace it and have your gate running again, often the same day. But if it’s a legacy board that’s been discontinued, the honest answer is that chasing used or rebuilt parts is a gamble, and in many cases a new operator costs less than the labor plus an unreliable board. Call (877) 610-2993 with the model number and we’ll tell you straight before you spend anything.
In Selden, the usual cause is post heave. Winter freeze-thaw cycles shift the hinge post slightly, the gate panel drops or twists, and the photocells that were aligned in the fall are no longer aimed at each other. The sensor trips because it’s not seeing its own beam. We realign the gate geometry and re-aim the sensors, and the false trips stop. No new motor needed. Call us to schedule a diagnosis.
Yes. Battery backup can be added to most operator models, including Linear and BFT units, and it works alongside solar charging. The battery holds enough reserve to run the gate for several days without grid power, which matters during Long Island storm season when outages can last long enough to trap your car in the driveway. Expect to pay $350-$700 depending on your operator type. Call for a free estimate.
Usually not. A dragging gate in Selden is almost always a post or hinge problem, not a motor problem. The motor is being asked to push against a geometry that has shifted. We reset the post, replace the hinges if they’re worn, and the motor stops straining. The repair typically runs $300-$600, far less than a new operator, and it fixes the actual problem instead of burning out a fresh motor on the same bad post. Call (877) 610-2993 and we’ll take a look.
Yes. Town of Brookhaven pool barrier code requires self-closing, self-latching gates with working entrapment protection, and that’s exactly what we retrofit. If your operator can be brought up to compliance with new photo-eyes, a properly aligned latch, and maybe a new post, we’ll do that. If the operator is so old it can’t meet safety standards, we’ll install one that does. April is a busy month for this in Selden, so call (877) 610-2993 early to get on the schedule before the inspector arrives.
