AfterFast, Reliable Gate Motor & Opener Across Los Angeles
A gate motor replacement in Los Angeles typically runs $1,100 to $3,400 installed, depending on whether you have a standard swing arm or an underground operator on a heavy ornamental driveway gate. Most motor repairs land between $220 and $480. We run our own crews out of the Los Angeles office, so we can usually have a technician at your driveway within one business day, often same-day for a dead opener.
If your gate stopped moving, or it shudders and grinds but will not clear its travel arc, call us at (442) 255-3886. We will diagnose the motor, the control board, the limit switches, and the mounting alignment before we quote anything, and the price is agreed before a single bolt gets turned. We have been working on Los Angeles gates long enough to know what the ground, the sun, and the age of the home are doing to your opener.
Why Ironworks Gate Co. Is Los Angeles’s Preferred Gate Motor & Opener Company
Ironworks Gate Co. has been answering the phone for Los Angeles homeowners for over 42 years. We started in 1984, and our owner, Victor Salinas, still runs the company the way a blacksmith runs a forge: straight answers, honest work, and a guarantee we will not hide from. The crews that come to your home are background-checked and uniformed, and they work under a simple code we call K.E.Y.S. – Krafted right, Every time, Your home first, Standing behind it.
Homeowners in neighborhoods from South LA to the foothills keep our number because of the 90-Day Done Right Promise. Written down, no paperwork to file, no arguing. If the opener is not right, we come back and make it right. That applies to every motor install, every repair, and every safety device we touch.
We also train and equip our technicians on nine automation brands, which matters more in Los Angeles than most places. A 40-year-old estate in the 90001 ZIP might have a FAAC underground operator from the 1990s, while the newer home two streets over runs a LiftMaster swing arm. You do not want a technician learning your brand on your driveway. We already know it.
Our Gate Motor & Opener Services in Los Angeles
Our full Gate Motor & Opener scope covers repair, installation, retrofits, and access integration. Below are the jobs we handle most often across Los Angeles.
Motor Installation
We install and program swing arm, slide, and underground operators. In Los Angeles, most installations happen on ornamental wrought iron and steel tube gates that weigh three to six times more than a standard suburban gate. That weight changes the torque math. We size the operator to the actual gate mass and cycle count, not a catalog guess, and we calibrate the soft-start and soft-stop settings on-site so the gate does not slam the living daylights out of its own posts.
Motor Repair
Most Los Angeles motor failures are not the motor itself. We see burned-out capacitors, dead control boards, stripped limit cams, and arms bent because a post shifted and jammed the geometry. In 90001 through 90003 especially, we regularly find that the motor is fighting a gate that has been pulled out of true by ground movement. We will tell you if the motor is actually the problem, or if the motor failed because something under the gate failed first. Repairing the symptom without fixing the footing just burns out another motor in two years.
Linear Motor
Linear arm operators are the most common setup on Los Angeles swing gates. They are reliable, but they are also the first component to bind when a hinge post drifts off plumb. We carry linear arm kits and replacement gears for LiftMaster, FAAC, and Mighty Mule, and we re-weld and reshim mounting plates when the drift has pulled the pivot out of its original arc.
Slide Motor
Slide gates in Los Angeles run on rack and pinion drives along concrete or asphalt driveways. When rain saturates the soil and the slab heaves even half an inch, the rack teeth no longer mesh cleanly with the drive gear, and the opener starts to labor, grind, or trip its clutch. We reset the rack alignment, re-shim the track, and replace worn drive gears before they chew themselves apart. Several of our slide motor repairs could have been avoided with a seasonal alignment check, which is one reason we offer the $89 Seasonal Tune-Up.

Trusted Brands We Service in Los Angeles
We carry parts and programming manuals for the brands you are most likely to have on a Los Angeles driveway. That includes LiftMaster, the most common brand on swing gates across South LA, FAAC, which shows up constantly on older estate properties with hydraulic and underground operators, and Mighty Mule, which we see on a lot of lighter tube gates and DIY retrofits. Our Gate Motor & Opener in Los Angeles service trucks keep common boards, remotes, photocells, and capacitors stocked, so the fix often happens on the first visit rather than after a parts delivery.
Common Gate Motor & Opener Problems We See in Los Angeles Homes
- Post drift from minor seismic activity. Los Angeles sits on soil that never truly settles. Every small quake and every wet winter nudges concrete gate posts a fraction of an inch out of plumb. The gate still closes, but the latch strike plate no longer lines up, the arm operates under increasing load, and the motor dies young. We correct the post first, then the motor.
- UV-baked control boards and cracked housings. With 280-plus sunny days a year, Los Angeles heat exposure shortens the life of plastic motor housings, wire insulation, and control board solder joints. Wires become brittle, capacitors bulge, and intermittent faults appear. We replace with components and wiring routed for long-term UV survival.
- El Niño ground heave jamming underground operators. After a heavy winter rain, the clay-heavy soil around many Los Angeles driveways expands and lifts. Underground operators on heavy custom gates are the first to seize, because their housing is set into the same concrete that just moved. We see this concentrated in older neighborhoods with mature trees and saturated ground.
- Worn rack and pinion teeth on slide gates. On longer driveways across Los Angeles, slide gates weigh more and cycle more, and the teeth take real wear. We replace rack sections and drive gears before the motor strips, which keeps a $400 gear failure from becoming a $2,100 operator replacement.
Pricing for Gate Motor & Opener in Los Angeles, CA
A standard swing arm motor replacement in Los Angeles runs $1,100 to $2,600, installed and programmed. A slide gate operator on a heavy driveway gate runs $1,800 to $3,400. Underground operator work on heavy ornamental gates starts around $3,200 and goes up with the gate weight and the excavation required. Most motor repairs land between $220 and $480, with control board replacements common at $350 to $750 depending on brand.
What moves the number: the gate’s true weight, whether the posts are still plumb, the brand of operator already installed, and whether we need to re-route conduit or add new safety edges to meet current code. The price is always put in front of you and agreed before work starts. We offer $50 Off Any Repair Over $250, and a permanent 5% Senior and Veteran discount.

FAQs - Gate Motor & Opener in Los Angeles
Your gate post is shifting because the concrete footing was never deep or wide enough for Southern California soil, which moves with seismic activity and moisture changes. In the 90001 through 90003 ZIP codes, we see this constantly. The fix is resetting the post footing with a deeper concrete pour, then re-aligning the operator arm and latch so the geometry is clean again. Call (442) 255-3886 and we can check your post in one visit.
Sometimes, yes. Under UL 325 and the California Building Code, if your repair touches the operator, the control board, or the safety circuit, the system may need to be brought up to current entrapment-protection requirements. That usually means verified photocells, an audible alarm, and proper force settings. We fold that compliance work into every Los Angeles estimate, because we do not want to hand you a working motor that leaves you exposed legally.
The most common cause in Los Angeles is soil heave under the driveway slab, which pushes the rack slightly out of line with the drive gear. The permanent fix is re-leveling the track and re-shimming the rack sections, not forcing the motor to muscle through the misalignment. We also check the wheel carriers and guide rollers, because mud and grit from winter rains accelerate wear in the same spots.
For a standard lightweight tube gate, yes. For a heavy ornamental wrought iron gate like most of what we service across Los Angeles, solar rarely delivers the consistent torque and cycle count those gates need, especially in shaded driveways or homes with frequent visitors. We stock Mighty Mule solar kits for the right jobs, and we will tell you if your gate is too heavy for solar before you spend a dollar.
Because the soil under your driveway does not stay still in Los Angeles. Clay-heavy ground absorbs winter rain, expands, and shifts the operator housing and its internal gear alignment. We have rebuilt several of these on older Spanish-revival properties in South LA with the same root cause: the underground box was set into soil that heaves, not into a stable, drained footing. The correct repair is resetting and resealing the operator pit, not swapping in another motor that will fail on the same schedule. Call (442) 255-3886 for an exact quote. Estimates are free.
Seismic Soil, Heavy Iron, and the Los Angeles Gate Problem
Here is the thing that only a Los Angeles gate technician truly learns. In Phoenix or Dallas, a gate motor fails because it is old, or a gear wears out, or a capacitor dries up. Those failures happen here too, but we have an additional failure mode that most other cities will never see. The ground in Los Angeles moves. Small quakes, the ones nobody thinks twice about, shift concrete gate posts by fractions of an inch. Dry summers shrink the soil. El Niño winters soak it and make it swell. Over ten or twenty years, that adds up. The post is no longer where the gate and the operator expect it to be.
On a heavy ornamental swing gate, that means the latch strike plate misses by a quarter inch, and the arm has to push harder every cycle. On a slide gate, the rack and pinion fall out of perfect mesh and the motor grinds. The opener fails, but the opener was never the disease. It was the victim. A technician from out of town will replace the motor and leave. Then the new motor burns out against the same misaligned post in eighteen months. We see it all over South Los Angeles, from the craftsman bungalows with original 40-year-old iron to the newer Spanish-revival estates with fully clad perimeters.
We rebuilt a 400-pound ornamental swing gate on a 1920s Spanish-revival home in the 90002 ZIP after the hinge post shifted a full inch out of plumb. We reset the post footing with a 24-inch concrete pour, replaced the worn FAAC operator with a new linear arm model, and integrated the existing keypad entry and safety photocells so the gate swings silently and latches cleanly every time. That gate had been through three motors from other companies before we got the call. The motors were not the problem. The ground was.
We also deal with the regulatory layer that catches out-of-town contractors. California’s automated-gate entrapment-prevention law, enforced through the California Building Code and UL 325 compliance, means that any motorized gate repair in Los Angeles that touches the operator or control board can trigger a required safety-device inspection. We build that compliance into every estimate, because a working gate that is not code-compliant is a liability waiting on the wrong moment.
