AfterFast, Reliable Gate Installation Across Altadena
A new driveway gate in Altadena typically runs $2,800-$6,400 for a standard single swing gate, and $4,900-$11,000 for a wide double gate with automation, depending on materials, operator type, and whether solar power is needed. Most installations we schedule are completed within 5-10 business days once permits clear. If you’re rebuilding after the Eaton Fire or simply replacing a gate that’s sagged past saving, call (626) 624-4196 and we’ll give you a written price before any work starts.
We work throughout Altadena, from the Craftsman bungalows below Lake Avenue to the equestrian properties off Chaney Trail and the foothill streets near Eaton Canyon. Our crews know the permitting path through LA County Building & Safety, and we’ve been installing gates on post-fire lots since the rebuild began. That local knowledge matters when the county inspector shows up.
Why Vance Gate Repair Pasadena Is Altadena’s Preferred Gate Installation Company
Altadena homeowners call us because we hand over a written price before the first post hole is dug. That’s Haven Standard Clause 1, and it’s not negotiable. The number you see on the written scope is the number on the invoice. No verbal estimate that drifts upward midway. No surprise line item for “additional concrete work” after the footing is poured. Our customers in Altadena have told us, frankly, that other contractors wouldn’t put anything in writing. We always do.
Since 2014, Adrian Vance and our team have completed 22,000+ gate repairs and installations, every one with a documented photo record. For Altadena specifically, that record matters because the county’s post-fire rebuild process often asks for evidence of what was installed and how. Our technicians photograph the footings before concrete, the operator wiring, the final gate alignment, and hand you the full record before leaving. Same habit Adrian developed doing commercial access-control work: leave the site better documented than you found it.
Every crew member dispatched to Altadena is background-checked and uniformed, with name and photo sent before arrival. A live person answers our phones 24/7. If your gate fails at 2 a.m. during a Santa Ana event and you need someone who can talk you through securing it, you’ll reach a human, not a voicemail tree.
Our Gate Installation Services in Altadena
We install the gate type that fits your driveway, not the one that’s easiest to quote. Here’s what that looks like in Altadena’s housing stock.
Driveway Gate Installation
Most Altadena homes between Mendocino Street and Altadena Drive have driveways between 10 and 14 feet wide, which means a single swing gate or a compact sliding gate fits without excessive excavation. We measure run, slope, and clearance before recommending a configuration. For driveways that rise steeply from the street, a sliding gate often outperforms a swing gate because the slope doesn’t fight the operator arm every cycle.
Pedestrian Gate Installation
Pedestrian gates in Altadena take a beating from foot traffic, but the real killer is the mountain wind that slams them against their stops. We set pedestrian gate posts at least 36 inches deep, more in decomposed granite soils, and we add a positive latch rather than relying on a gravity close. A pedestrian gate with a keypad entry is now standard on many post-Eaton Fire rebuilds we handle, since county fire-rebuild approvals frequently require controlled access for emergency crews.
Sliding Gate Installation
Long, level driveways in the mid and lower reaches of Altadena are good candidates for sliding gates, particularly when the driveway is also a fire-access lane. Sliding gates don’t need swing clearance into the property, which matters on narrow lots where a swinging leaf would clip a retaining wall or a parked car. We’ve installed sliding gates on several Lake Avenue corridor properties where swing radius simply doesn’t exist.
Swing Gate Installation
Swing gates are the default for Altadena’s older homes, and they work well when the driveway apron is fairly flat. The problem we most often correct: post footings that were sized for a 1940s wrought-iron gate but are now being asked to carry a heavier modern steel gate with an operator bolted on. Our standard for a single swing gate in this area is a 36-42 inch deep footing with rebar cage; for a wide double gate on a gravel drive, we go deeper and wider, and we’ll tell you why in writing before we dig.
Double Gate Installation
Double gates are everywhere in North Altadena, especially on equestrian properties along gravel access roads. These gates frequently span 14-20 feet, and we size the operator and the hinge posts to carry that span through wind load rather than just dead weight. A double gate that looks fine on a windless day can twist alarmingly in a sustained Santa Ana. We’ve seen it. We engineer for it.

BeforeAfterTrusted Brands We Service in Altadena
We install and service operators from LiftMaster, FAAC, BFT, and Linear, among others. That means we don’t steer you toward a brand we happen to have in the truck. If your old gate had a LiftMaster and you want to retrofit a new operator, we’ll quote it. If you’re starting fresh and a BFT heavy-duty operator fits the wind load better, we’ll quote that. We keep common parts for these systems stocked, which shortens turnaround for Altadena customers when a control board fails or a limit switch needs replacing mid-install. For deeper context on how we approach every gate project, see our Gate Installation team’s process page.
Common Gate Installation Problems We See in Altadena Homes
These are the issues we encounter week after week in Altadena, and they’re specific to this foothill geography.
- Undersized solar panels on long driveway runs. In the upper reaches of Altadena, mains power often doesn’t reach the gate, and a solar opener sized for flatland Los Angeles simply underproduces during dusty Santa Ana weeks. We size panels for the actual dusty-season output along the mountain front, not the optimistic spec-sheet number.
- Post footings that fail on decomposed granite. Decomposed granite is common in North Altadena, and it does not hold a shallow footing the way clay does in Pasadena. A first-time installer following a generic template might pour 24 inches and call it done. That gate sags before the first high-wind season. We go deeper on DG soils, and we photograph the hole before concrete goes in.
- Wrought-iron gates from the 1930s-1950s with corroded hinge hardware. Altadena’s original homes often still have their original gates, and the hinges are frequently rusted to the point of near-failure. The gate itself may be beautiful. The hardware is not. We can automate many of these original gates, but we replace the hinge pins, plates, and post anchors as part of the job, and we’ll show you photos of exactly what we found.
- Post-fire rebuild concrete poured too shallow at the driveway apron. On lots where the Eaton Fire took the fence and gate, the new driveway pour sometimes doesn’t account for the swing radius of the gate that will be installed later. We see aprons poured 3 inches thick where the gate post will sit, and those footings crack within months under repeated torque. We catch this before installation, and we’ll tell you if the slab needs a spot repair before we proceed.
Pricing for Gate Installation in Altadena, CA
Here are honest numbers for Altadena’s market, so you know what to expect before you call. A standard single swing gate with a LiftMaster or FAAC operator runs $2,800-$4,600. A wide double gate, common on North Altadena equestrian properties, runs $4,900-$8,500 depending on span and whether you need solar power. A solar gate opener package on a long gravel driveway, with panel, battery, and charge controller sized for dusty-week output, adds roughly $1,200-$2,400 to the total. Pedestrian gates with keypad entry run $1,400-$2,800.
What changes the price: gate width and weight, post footing depth (we go deeper on decomposed granite), operator brand and heavy-duty rating, solar versus line-voltage power, and whether the county requires entrapment protection and keypad access as part of your post-fire rebuild approval. The price we quote is the price you pay. Written. Before work starts. Call (626) 624-4196 and we’ll come measure, assess the soil, and hand you a number.

FAQs - Gate Installation in Altadena
Yes. If your property is in an LA County-designated Very High Fire Hazard Severity Zone and the rebuild falls under the current fire-rebuild ordinances, a new automated gate typically requires approval through LA County Building & Safety, not a city hall. The county inspects the installation for entrapment protection, proper set-back, and in many cases controlled access for fire crews. We handle that permitting path routinely for Altadena customers and can tell you exactly what your specific lot requires after a quick site look. Call (626) 624-4196 and we’ll walk you through what the county will expect.
Because running conduit and line-voltage power from the house to a gate 150-400 feet down a gravel drive is often $3,000-$8,000 in trenching alone, and the mountain wind doesn’t care how you power the gate, only that it opens when the wind is blasting dust into the panel. A properly sized solar system with a battery bank avoids the trench, but only if the panel output is matched to Altadena’s dusty Santa Ana weeks, not to a clean desert test curve. We size for the real-world output, and we document the system in your job record. Call (626) 624-4196 for a written estimate on solar or line-voltage power.
Usually, yes. The gate itself is often perfectly sound, but the hinge hardware is the failure point after 70-80 years of mountain wind. We replace the hinge pins, plates, and post anchors, then add a modern operator with entrapment protection. The county will inspect the entrapment protection on your post-fire lot, so automating an original gate is not about bolting on a motor; it’s about bringing the hardware and safety features up to current code while keeping the gate you have. Call (626) 624-4196 and we’ll assess what your original gate needs.
Yes, with the right operator and the right post footings. A 16-foot double gate on a sloping gravel drive needs a heavy-duty operator rated for the gate weight plus wind load, and it needs footings deep enough to resist the repeated torque of opening against the slope. Up on a gravel access road in North Altadena’s equestrian zone, our crew swapped a rusted pipe-frame ranch gate for a 16-foot swing gate with a Ghost Controls solar opener and a new 6-foot-deep post footing, because the old hinge post had failed exactly as expected under decades of Santa Ana wind load, and county fire rebuild rules required entrapment protection and a keypad entry for the first time. That’s the standard we work to on every wide double gate in this area. Call (626) 624-4196 for a written price on yours.
The county inspector typically checks four things on an automated gate in a fire-rebuild zone: entrapment protection (photo-eyes and/or contact edges that stop and reverse the gate), the electrical or solar system’s grounding and load rating, the set-back distance from the roadway or fire-access easement, and the access-control system (keypad, intercom, or fire-department key switch) that allows emergency crews in. If any of those four are missing or substandard, the installation fails inspection. We’ve been through this process on post-Eaton Fire rebuilds in Altadena enough times to know exactly what the inspector will look at, and we build every installation to pass the first time. Call (626) 624-4196 and we’ll put it in writing.
