No voicemail, no chat bot. You’ll get a written price before any work starts, and the number on the invoice is the number you agreed to at the door.

Los Altos is not a flat, uniform suburb. The terrain climbs from the flatlands near El Camino Real up into the steep hills above Foothill Expressway, and that changes how gates fail. Our team is on the road to Los Altos constantly, which means we know the difference between a gate that sagged because of saturated clay on a hillside lot and one that stripped a gear because a winter gust hit a solid redwood infill. We see both. Usually in the same week.
Why Calder Gate Repair San Jose Is Los Altos’s Preferred Electric Gate Repair Company
Los Altos homeowners expect a certain standard. The town is quiet, the properties are private, and nobody wants a gate that groans, lurches, or sits half-open after a storm. We built our reputation here by showing up on time, with a trackable arrival window you can see on your phone, not a four-hour guess. You’ll know who’s coming, what they look like, and when they’ll be at your gate.
Every repair is covered by the 365-Day Done Right Promise. That means a written guarantee on every job, and if the repair fails within 365 days, Calder returns at no charge. No fine print. We state it in writing before we leave. Nico Alvarez, our lead technician, holds every job to that standard personally. If it’s not right, we make it right. That’s the deal.
We work on the brands Los Altos homes actually have. FAAC and BFT operators are common on the hillside estates up near the Los Altos Hills border, and Linear and Viking appear regularly on mid-century ranches closer to downtown. We stock parts locally for Los Altos customers, which is why we can often complete a repair on the first visit instead of ordering a board and coming back next week.
Styles & brands we work with





Commercial Gate Operator in Los Altos
A commercial gate operator in Los Altos is a heavier-duty motor and drive system built for gates that cycle frequently and carry more weight than a standard residential opener. In Los Altos, we see these on shared private lanes, small HOA entrances, and gated estates where the driveway gate is wider and heavier than what a homeowner-grade opener can handle over years of daily use. A commercial operator typically costs $850 – $1,600 installed in Los Altos, depending on the gate’s length, weight, and whether the existing posts and footings can be reused.
When a Commercial-Grade Operator Makes Sense
The test is cycle count and gate mass. If your gate opens and closes more than 20 times a day, or if it’s a solid steel or heavy wood gate over 12 feet, a standard residential operator will wear out gears and boards prematurely. We’ll tell you honestly if your opener is undersized for the load. On a hillside lane in Los Altos, wind load adds torque that a light-duty opener simply wasn’t designed to absorb.
What We Check Before Recommending a Commercial Operator
Post integrity comes first. Saturated clay soil on Los Altos hillsides can rotate a post out of plumb, and no operator, commercial or otherwise, will last if the foundation moves. We check footings, hinge welds, rack alignment, and the safety edges before we quote a replacement. The written price includes everything, so there’s no surprise line item after the fact.
Automatic Gate Repair in Los Altos
Automatic gate repair in Los Altos covers the full system: the opener, the motor, the limit switches, the safety sensors, the keypad, the remote receiver, and the control board. Most automatic gate repairs in Los Altos run $280 – $520 for the service call, diagnosis, and common parts. If the control board is fried or the motor is seized, the price can push to $700 – $950, and we’ll show you the parts cost and labor separately in a written quote before we touch a bolt.
Sagging Gates on Hillside Lots
Los Altos’ hilly terrain means gate posts and footings face unusual lateral and vertical soil pressure, especially on slopes where saturated ground from winter rains can shift and undermine a post in a single storm. A gate that swung true in September can be scraping the driveway by February. That’s not your opener failing, it’s the earth under the post moving. We reset the post, deepen the footing, and only then recalibrate the operator, otherwise you’re paying for a repair on top of a bad foundation.
All Major Brands, Repaired Same Visit
We’re factory-familiar with LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That’s not marketing language, it’s inventory and training. When we roll up to a Los Altos property, we carry the boards, remotes, safety sensors, and limit switches for the brands that dominate this area. One visit, one repair, one written guarantee.

When a winter storm swept through Los Altos Hills, we got a call from a homeowner on Miranda Road whose 16-foot solid-wood swing gate had sagged so badly it was scraping the driveway. Our tech found the hinge post had rotated in its footing after days of rain softened the clay soil. We excavated, poured a deeper concrete footing with rebar, and reset the post before rehanging the gate and recalibrating the LiftMaster opener. By the next morning, the gate swung true again, even with gusts still blowing.
Trusted Brands We Service in Los Altos
We carry repair parts for the gate opener brands you’re actually likely to have in Los Altos, and we keep the common failure components stocked locally so you’re not waiting on a ground shipment. FAAC operators are common on hillside estates; BFT shows up on newer automatic sliding gates in the flatlands; Linear and Viking are staples of 1990s and early-2000s installations across Los Altos. Our technicians are trained on all of them, and we diagnose by behavior, not by brand sticker. If your gate is moving slowly, stopping mid-cycle, or not responding to a keypad that still beeps, we’ll identify the failing component fast and quote the repair in writing before work begins.
This page’s focus is Electric Gate Repair, and our team handles everything from a single limit switch to a full operator replacement. If you’re in Los Altos, you get the same written-price guarantee we extend across the entire South Bay.

AfterCommon Electric Gate Repair Problems We See in Los Altos Homes
- Wind-damaged rack and pinion gears. Solid wood and metal infill gates act like sails during winter gusts. The wind load transfers through the gate leaf into the opener’s rack and pinion, and the plastic gear strips. We see this most on exposed hillside driveways where there’s nothing to block the wind.
- Posts rotated in saturated clay. Los Altos sits on clay-heavy soil that holds water for days after heavy rain. When the ground saturates, a hinge post can rotate a few degrees, which is enough to make a 14-foot gate sag and bind against the driveway.
- Clutch jams after a hurried manual release. During a storm power outage, homeowners pull the manual release lever, but if the gate hasn’t been released in years, the clutch sticks or the chain binds. Then the opener won’t re-engage when power returns, and we get the call.
- Safety sensor misalignment from wind or minor impacts. A gust can flex a gate enough to knock the photo eye out of alignment. The gate refuses to close, or reverses mid-cycle, and the homeowner thinks the motor is dying. It’s usually a 20-minute fix, but it requires a tech who knows where to look.

FAQs About Electric Gate Repair in Los Altos
Most residential swing and slide gate operators in Los Altos have a manual release lever or key located on the operator housing, usually below the control board cover. Pulling it disengages the motor from the drive mechanism so the gate can be pushed open or closed by hand. The risk is that if it hasn’t been released in years, the clutch can stick or the chain can bind. If the lever won’t move with moderate force, don’t force it, call us at (669) 666-6859 and we’ll walk you through it or dispatch a tech. Once power returns, re-engage the lever until it locks, then run a full open-close cycle to confirm the travel limits are still set.
Because the clay soil under your hinge post is expanding when saturated. Los Altos winters bring repeated soak-and-dry cycles, and clay swells and softens, allowing the post to rotate slightly out of plumb. In summer, the same soil is dry and compacted, so the post holds. The sag isn’t the gate bending, it’s the post moving. The fix is resetting the post in a deeper footing with rebar, sometimes with added concrete mass on the uphill side. If you wait, the gate will drag and eventually damage the opener’s gears.
Yes, and it’s one of the most common storm-related repairs we do in Los Altos. Solid wood or metal gate panels act like sails in high wind. That force travels through the gate leaf into the rack and pinion or the swing arm, and the sacrificial gear inside the operator strips. It’s designed to fail before the motor burns out, but it still leaves your gate dead. We replace the gear, check the gate’s alignment and hinge welds, and often recommend a wind-rated operator if your driveway is exposed to open gusts.
The keypad is getting power and sending a signal, but the operator’s control board may have lost its travel limits during the outage, or the manual release was left disengaged after someone opened the gate manually. The board may also have been damaged by a power surge when the grid came back. We see all three in Los Altos after every extended outage. The fix is usually a limit relearn or a re-engage of the clutch, but if the board is fried, it’s a $320 – $650 replacement depending on brand. A surge protector on the operator circuit is a cheap way to prevent the board damage.
Because the wind is pushing the gate from behind while the operator is closing, so the gate overshoots the soft-close zone and slams into the end stop or the lock. This happens most on hillside properties in Los Altos Hills where there’s no windbreak. The operator’s force settings and closing speed need to be adjusted for the wind load your specific site sees, or we can install a wind sensor that holds the gate open in unsafe gusts. It’s a calibration and hardware fix, not a full operator replacement, and it costs less than you’d expect. Call (669) 666-6859 for a quote specific to your gate and your hill.
