Fast, Reliable Gate Installation Across San Marino
Gate installation in San Marino runs between $2,400 and $11,000 for a custom driveway gate, with pedestrian gates starting around $900 and full automation packages adding $1,600 to $4,500 depending on operator brand and pillar work. Most San Marino projects take two to four weeks from permit submission to final walkthrough, and the single biggest variable is whether your estate’s original 1920s to 1950s pillars need reinforcement before a motorized operator can go on. We know San Marino’s approval process cold. Call (626) 628-9548 and you’ll get Hal or someone from his crew, not a recording.
We work in San Marino every week, and we know what this city’s gates demand. The Architectural Review Board here has jurisdiction over anything visible from the street. That includes gate frames, finishes, pillar caps, and even which direction a swing gate opens. If you’re in the Oak Knoll, Mission District, or Huntington Library area, those rules apply to your property just as much as they do to the estates along Lombardy Road or St. Albans Drive. Getting the approval right the first time is the difference between a smooth installation and a stop-work order.
Why Gatewood Fence & Gate Is San Marino’s Preferred Gate Installation Company
Hal Gatewood has been at this since 2001, and the shop carries his name. That means something in San Marino, where homeowners want to know the person quoting the job will be the person who shows up. We’re not a franchise and we don’t subcontract your gate to a rotating crew. Hal or his long-time crew members do the work, and every invoice has Hal’s name on it. The address is published. The license number is published. Drive by and look at the shop if you want. That’s how accountability used to work, and it’s how we still run things.
Our San Marino customers call us because their last gate contractor got the architectural piece wrong. Maybe they mounted an operator on a pillar that was never designed for one. Maybe they switched a gate from swing to slide without checking whether the HOA even allows slide gates on that street. Some of them had to tear out brand-new work and start over. We hear those stories a lot, which is why we handle the Architectural Review Board submission as part of every San Marino gate installation we quote. No separate paperwork fee, no “that’s your responsibility.” We’re local enough to know the process and stubborn enough to get it right.
Every job is backed by our 90-Day Done Right Promise in writing. If something isn’t right, one call brings us back. We also answer the phone around the clock with a live person. Not a voicemail. Not a call center. In San Marino, your gate is often the first thing a visitor sees and the last line of physical separation between your family and the street. When it fails, you shouldn’t have to leave a message and hope.
Our Gate Installation Services in San Marino
Driveway Gate Installation
Driveway gate installation in San Marino almost always involves working with estate pillars built between 1920 and 1960. Those pillars are beautiful, but they were poured for decorative iron hung on pin hinges, not for the torque of a modern operator arm. We assess the hinge post, check for existing conduit pathways, and often recommend a discreet reinforcement or a custom steel sub-frame that carries the operator load without touching the historic masonry. In the Oak Knoll area, we installed a Viking swing gate operator on original 1930s brick pillars where the post footing had no conduit pathway. We worked with the management company to submit architectural drawings for a surface-mount rack and pinion conversion, then fitted a LiftMaster Elite opener with safety photocells and a keypad entry system, all without altering the historic pillar caps.

Pedestrian Gate Installation
Pedestrian gates in San Marino range from simple courtyard entries to matched gate pairs set into estate walls. A basic steel pedestrian gate starts around $900; a custom ornamental gate with picket spacing, arch work, and specialty hinges runs $1,800 to $4,200. Most San Marino pedestrian gates need to match the driveway gate’s finish and style, and the ARB cares about that match. If your property is on a corner lot or your gate sits within the front setback, we handle the review paperwork before we cut steel.

Sliding Gate Installation
Sliding gates make sense when a driveway slopes upward or when swing gates would block a motor court. But in San Marino, many driveway pillars are only 12 feet apart, and a slide gate needs at least 1.5 times the gate opening in lateral track run to slide fully open. That means the gate has to cantilever, or the track has to run along a side wall or hedge line. We survey the driveway before recommending a slide gate, because mounting a slide gate where the geometry doesn’t support it is exactly the kind of mistake that gets a San Marino homeowner a rejected ARB application.

Swing Gate Installation
Swing gates remain the standard in San Marino because the city’s estates were built around them. A single swing gate with a LiftMaster or FAAC operator typically runs $3,800 to $7,500, including pillar reinforcement, safety edges, and electrical. Double swing gates add $1,200 to $3,000 depending on width, weight, and whether you need matched operators. The wind load here matters more than most people realize. Santa Ana events push heavy ornamental gates hard against their open stops, and a properly set operator arm and limit switch is the difference between a gate that lasts 15 years and one that bends its arm in the first big wind of October.

Trusted Brands We Service in San Marino
We’re certified to install and service LiftMaster, FAAC, BFT, Mighty Mule, and five other major gate brands. For San Marino, we stock common LiftMaster Elite opener parts and FAAC hydraulic arms locally, so when a spring breaks or a control board goes down, you’re not waiting on a warehouse in another state. We also carry the safety photocells and loop-detector wire that San Marino’s hard municipal water tends to corrode faster than homeowners expect. If you already have a preferred operator brand, tell us on the call. We’ll match the system to your existing gate rather than selling you a brand swap you don’t need.
Common Gate Installation Problems We See in San Marino Homes
San Marino’s housing stock creates a predictable set of gate problems. Here’s what we run into most often:
- Slide gates specified where swing gates are required. Some HOAs and the ARB require swing gates for architectural consistency on certain streets. Install a slide gate without checking, and you’ll be pulling it out and eating the cost.
- Operator arms bending in Santa Ana winds. Inland valleys get wind events that coastal LA never sees. A heavy 14-foot gate slamming against its open stop puts enormous stress on the operator arm. We set limit switches and install positive stops on every San Marino swing gate.
- Pillar fatigue on 1920s-1950s masonry. The brick and cast-stone columns on San Marino estates weren’t built for motorized operators. Without reinforcement, the hinge post starts moving, and the gate sags within a year. That’s the most common callback we fix after another company’s install.
- Conduit and wiring degradation from alkaline soil. Buried loop-detector wire and low-voltage conduit in San Marino’s soil corrodes faster than in coastal communities. We spec heavier-gauge wire and corrosion-resistant conduit on every new install.

FAQs - Gate Installation in San Marino
Yes. San Marino’s ARB has jurisdiction over gate structures visible from the street, and that includes operator heads, arms, keypads, and any bracket or conduit mounted on the pillar face. You need approval before work starts, even if the gate itself isn’t changing. We prepare and submit the drawings as part of the installation. Call (626) 628-9548 and we’ll tell you exactly what your specific property needs.
Usually not, and here’s why: a slide gate needs at least 1.5 times the gate opening in track run to fully clear the driveway. If your pillars are 12 feet apart, you’d need roughly 18 feet of lateral run, which most San Marino front setbacks don’t have. In that situation we recommend a double swing gate or an articulated gate, and we’ll talk you through the tradeoffs before you spend a dime. Call us for a site assessment at (626) 628-9548.
We run a discreet surface-mount conduit along the inside face of the pillar, painted to match the masonry or stucco, then route low-voltage wiring to the operator and keypad. If the property is in a historic district or the pillar is particularly significant, we can also use a solar operator with a battery backup, which avoids conduit entirely. The ARB reviews either approach, and we include the drawings in your estimate. Call (626) 628-9548 for a free site evaluation.
Some San Marino HOAs do require a specific keypad or telephone-entry system, especially on shared motor courts and private streets with multiple residences. If your HOA has an access-control standard, we install to that spec and coordinate with the management company on gate timing, resident codes, and emergency fire access. Tell us which HOA you’re in when you call, and we’ll bring the right hardware. Reach us at (626) 628-9548.
Santa Ana winds push heavy ornamental gates hard against their open stops, which accelerates hinge fatigue and bends operator arms on swing gates faster than in coastal LA. For every San Marino install, we set positive mechanical stops and limit switches to absorb that wind load, and we use reinforced hinge barrels on gates over 10 feet wide. Call (626) 628-9548 and we’ll check the wind exposure on your specific driveway.
