AfterFast, Reliable Gate Motor & Opener Across Sylmar
A gate motor replacement in Sylmar typically runs $850 to $1,900 depending on the operator type and whether we need to re-set a failing post. Most repairs, including board swaps and limit switch adjustments, fall between $180 and $420 and can often be done the same day. If your opener quit at the worst possible moment, call Hal at (760) 361-6706. We answer live, 24/7.
Sylmar is not like the rest of the San Fernando Valley. It sits at the mouth of the Newhall Pass, which means Santa Ana wind events hit here first and hit here harder. That wind gets funneled through the pass before it disperses across the Valley floor, and anybody who has lived in Sylmar for a full year knows what that does to fences, gates, and anything with a motor bolted to it. We have been servicing gate motors and openers in this specific pocket of Los Angeles long enough to know which brands hold up here and which ones do not. When you call, you get a person who knows the difference between a gate on Foothill Boulevard and one up near the equestrian lots off Glenoaks.
Why Gatewood Fence & Gate Is Sylmar’s Preferred Gate Motor & Opener Company
Hal Gatewood has been doing this since 2001. His name is on the shop, his license number is published, and his address is not a P.O. box. That matters in Sylmar because there are a lot of older properties here, and older properties come with older gates, older posts, and older operators. The person who shows up needs to understand what a 1971 San Fernando earthquake did to the footings under your hinge post, not just how to unbolt a motor and slap a new one in.
We have fixed enough gate motors in Sylmar to know the common failure patterns by street. Up near the ranch properties along Glenoaks and Foothill, we see seized linear motors on heavy swing gates that were never intended for automated operation. In the tract home neighborhoods from the 1960s and 1970s, we see obsolete control boards on original operators that have no replacement parts available anywhere. When a Sylmar customer calls, we are not reading a script. We know that a slide gate off Polk Street that keeps derailing in October is probably a Santa Ana problem, not a wheel problem.
Calls are answered by a live person every hour of the day. Not a voicemail, not an automated tree, not a call center. Hal or a member of his crew picks up. We show up in the window we promise, we quote the price before we touch anything, and every job carries the 90-Day Done Right Promise in writing. If it is not done right, one call brings us back. No runaround.
Our Gate Motor & Opener Services in Sylmar
Motor Installation
Gate Installation in Sylmar for a full motor replacement runs $850 to $1,900 for a typical residential swing or slide gate. That includes the operator, mounting hardware, safety photocells, and setup of the remotes and keypad. If the existing post or footing is compromised, which we see regularly on Sylmar properties that predate the 1971 quake, that cost goes up because we correct the base before we hang anything new. A new motor on a leaning post is a new motor that fails within a season.
Motor Repair
Sylmar Gate Repair typically costs between $180 and $420. That covers limit switch failure, blown capacitors, stripped gears on older LiftMaster units, and control board diagnostics on DoorKing and Elite operators. We repair before we replace. If a board can be rebuilt or a gear can be swapped, that is what we do. The only time we recommend full replacement is when the part no longer exists, which happens a lot with 1980s and 1990s operators still running in Sylmar.
Linear Motor
Linear motors are common on the swing gates attached to Sylmar’s equestrian and ranch properties, and those gates are heavy. A 14-foot tubular steel gate from 1975 puts real torque on a Viking or Mighty Mule linear arm, especially when the hinge post has shifted. We service linear actuators, replace seized arms, and correct the gate geometry so the motor is not fighting the weight of the gate. A linear motor replacement in Sylmar typically runs $400 to $750, more if the post needs re-setting.
Slide Motor
Slide gates in Sylmar have a specific problem: Santa Ana winds catch the face of the gate like a sail and lift it off the track. That derailment strips the rack and pinion teeth on the opener. Slide motor replacement runs $750 to $1,500 in Sylmar, and we include checking the track, the wheels, and the guide rollers. If the track is still straight and the rack is intact, the repair might be a few hundred dollars. We will tell you which one you actually need.

Trusted Brands We Service in Sylmar
We are certified to service nine major gate brands, including the ones Sylmar homeowners actually have: LiftMaster, DoorKing, Elite, Viking, and Mighty Mule. Parts availability is a real issue for older operators, and we keep common boards, gears, and limit switches in stock for the brands we see most in Sylmar. That means fewer return trips and less waiting on a distributor. If you have an operator we do not stock parts for locally, we will tell you that up front and give you a realistic timeline.
Common Gate Motor & Opener Problems We See in Sylmar Homes
- Wind-induced track derailment. Santa Ana gusts funneling through the Newhall Pass catch flat-faced slide gates and pop the guide wheels off the rail. The gate then binds against the rack and the motor strips its own drive gear trying to move it.
- Post lean from the 1971 earthquake. We probe the concrete around every leaning hinge post in Sylmar. A surprising number of pre-1975 footings were cracked or shifted in the quake and never repaired, which is why the gate sags and the operator binds no matter how many times the hinges are adjusted.
- Obsolete control boards. Operators installed in the 1980s and 1990s often have boards that are no longer manufactured. When those fail, a board swap is not an option. We quote a full motor replacement and explain why it costs what it costs.
- Lack of modern safety photocells. Older gate operators in Sylmar often predate UL 325 entrapment protection requirements. That is a safety issue, not just a convenience issue. We retrofit photocells and edge sensors on older operators when possible so the gate can hold up to current safety standards.

FAQs - Gate Motor & Opener in Sylmar
They do not hurt the motor directly. They hurt the gate. The Newhall Pass funnels wind into Sylmar at speeds that nearby neighborhoods like San Fernando do not experience the same way. That wind pushes against a slide gate’s flat surface, lifts it off the track, and jams the rack. The motor keeps pulling, strips its own gear, and burns out. If your gate has come off the track twice, the motor is already working harder than it should. Fix the gate before the motor fails. Call (760) 361-6706 for an assessment.
Most of the time, yes. The gate itself is usually fine; it is the post underneath it that causes trouble. On ranch properties near Glenoaks and Foothill, we often find footings that were cracked in the 1971 San Fernando earthquake and never re-set. A new motor on a shifting post will bind and fail. We excavate the base, re-set the post, and then mount the new operator. Keeping the original gate is usually cheaper than replacing it, and it holds up to Sylmar’s wind if the geometry is right.
Because the gate is acting like a sail. The winds coming through the Newhall Pass hit it face-on, and if the gate is taller or older, the guide system cannot hold it. The fix is usually a combination of better guide rollers, a reinforced track, and sometimes our Gate Parts & Welding in Sylmar to add a wind brace across the frame. If the rack is already stripped, we replace the rack before the motor takes more damage. This is one of the most common calls we get in Sylmar between September and January.
No. Modern operators are required to have entrapment protection that meets UL 325. If your operator predates that requirement and has no photocells or edge sensors, it should not be left running as-is. We can retrofit photocells onto many older DoorKing and Elite boards. If the board cannot support them, we will tell you plainly and quote a replacement. Leaving a non-compliant gate operating is a liability on your property. Call (760) 361-6706 and we will tell you what your specific operator can support.
We do. Battery backup in Sylmar runs $350 to $650 installed, depending on the operator. It is a practical upgrade here because Santa Ana events knock out power in the canyon and foothill areas more often than people expect. A gate motor with battery backup will still open and close during an outage. For Sylmar homeowners with long driveways and no side gate, that is the difference between getting the car out and waiting for LADWP. We will quote it before the work starts.
If your gate motor is dead, noisy, or acting up in the wind, call (760) 361-6706. Hal Gatewood or one of his crew will answer, ask where in Sylmar you are, and give you a straight answer about what it will take to fix it. Free estimates, upfront pricing, and the 90-Day Done Right Promise in writing.
