Our Gate Installation team knows Sunnyvale block by block.

Why Liberty Gate Repair San Francisco Is Sunnyvale’s Preferred Gate Installation Company
We’re not a general contractor who “also does gates.” We’ve worked on gates exclusively for over 31 years, and that focus shows in Sunnyvale’s neighborhoods. Our 613 verified reviews averaging 4.9 stars include scores of jobs from 94086, 94087, and 94089 — homeowners who needed someone who understood why their 1972 wood gate was rotting at the base, or why their third operator in eight years had failed near Moffett Field.
Steven Lee, our owner, still serves as lead technician. That means Steven diagnoses it, Steven fixes it — no passing you between salespeople and subcontractors. When we quote a Gate Installation in Sunnyvale, we’re quoting from direct experience with your neighborhood’s soil conditions, setback requirements, and the specific corrosion patterns that affect hardware here.
We stock parts and weld on-site. For Sunnyvale’s older housing stock, that’s critical — because a “simple” gate replacement often turns into a post-replacement and footing job once we expose what’s been hidden underground for 50 years. One visit. One team. One accountability chain.
Our Gate Installation Services in Sunnyvale
Driveway Gate Installation
Most Sunnyvale driveway gates we install are automated swing or sliding systems replacing manual gates that never got upgraded — or replacing failing early automated systems from the 1990s. In 94087 and 94086, we’re seeing a surge of full replacements tied to ADU construction and streetscape remodels. Homeowners want wrought-iron style aluminum that complements new architecture without the maintenance burden of steel in our damp marine air. Typical driveway gate installation in Sunnyvale runs $3,500–$7,500 depending on width, automation, and whether we need to replace existing posts or footings.
Pedestrian Gate Installation
The original wood pedestrian gates in Sunnyvale’s 1960s–70s tracts are failing en masse. The wood rots at the bottom where sprinkler spray hits; the steel-pipe hinge posts rust underground where you can’t see it until the gate sags. We regularly core-drill new footings and install aluminum or powder-coated steel pedestrian gates with modern keypad or fob access — popular for side-yard entries that now need to secure ADU tenants or home offices. Pedestrian gate installation in Sunnyvale typically costs $1,800–$3,200.
Swing Gate Installation
Swing gates remain the default for Sunnyvale’s flat, rectangular lots — especially in the ranch-home neighborhoods where the driveway runs straight to the street. We install single and double swing systems with underground or articulated-arm operators from LiftMaster, FAAC, and Ghost Controls. Critical detail for Sunnyvale: we spec marine-grade hinge hardware and sealed DC operators for properties near the baylands, where standard residential-grade equipment corrodes prematurely. Swing gate installation ranges from $2,800–$5,500 for residential automation.
Sliding Gate Installation
Sliding gates make sense for Sunnyvale’s narrower lots or driveways with steep grades where a swing gate would scrape the sidewalk. We install cantilever and track-mounted systems for residential and light commercial properties — including the tech campuses along Central Expressway that need automated access control with vehicle detection loops. Sliding gate installation in Sunnyvale typically runs $4,200–$7,500 depending on track length, gate material, and access-control integration.

Trusted Brands We Service in Sunnyvale
We’re factory-familiar with nine major gate brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That matters in Sunnyvale because many homeowners inherit operators from previous owners — sometimes mismatched to the gate, sometimes discontinued. We carry common operator models, replacement PCBs, and gear sets on our trucks, and we can source same-day from regional distributors for less common parts. For commercial clients near Moffett Field or along the 94085 corridor, we spec and install DoorKing and FAAC access-control systems with telephone entry, loop detectors, and cloud-based management.
Common Gate Installation Problems We See in Sunnyvale Homes
- Rotting wood gate bottoms and rusted steel posts in 50+ year-old tract homes. The original wood gates in 94087 and 94086 neighborhoods were built with untreated fir or redwood and steel-pipe posts set in shallow concrete. After five decades of sprinkler contact and soil moisture, the wood disintegrates and the posts corrode below grade. We almost always need to core-drill new footings before installing a new gate — a step general handymen frequently miss.
- Accelerated corrosion of gate operator PCBs and drive gears in 94089 near Moffett Field. The salt-laden tule fog that rolls off the baylands creates a microclimate more aggressive than standard residential equipment is rated for. We’ve replaced operators in 94089 that failed at 7–10 years instead of their 15-year design life. We now spec sealed DC operators and marine-grade hardware for this pocket as standard practice.
- Mismatched new automated openers with legacy gates lacking modern safety features. Many Sunnyvale homeowners want to automate an existing gate that predates photoelectric sensors, edge sensors, or UL 325 safety standards. We evaluate whether the gate structure can accept modern safety hardware or whether a full replacement is the safer, code-compliant path.
- ADU-driven gate upgrades that don’t match original access patterns. New accessory dwelling units in 94087 often require rethinking who uses which gate, when, and how. We install dual-access systems — keypad for tenants, remote for homeowners, timer-based locking — that keep the property secure without creating daily friction.

These ranges reflect what we’ve actually quoted and completed in Sunnyvale over recent years. Every job is different — a 94089 property near the baylands may need upgraded corrosion-resistant hardware that adds 10–15% to material costs. A 94087 ranch home with original 1965 posts typically needs new footings, which adds $400–$800. We don’t guess over the phone. We inspect, measure, and provide a written estimate — free, no obligation. Call (628) 261-6223 to schedule.

FAQs — Gate Installation in Sunnyvale
Usually no — and we’d be doing you a disservice if we tried. In a 94087 ranch home off Fremont Ave, we replaced a rotting 1965-era wood pedestrian gate with a custom aluminum swing gate and a LiftMaster LA400PKG DC operator. The old steel hinge posts had corroded so badly that the gate sagged into the driveway; we had to core-drill new footings for 4-inch galvanized posts to handle the new automated opener. The homeowner chose wrought-iron style aluminum to match their new ADU, and we upgraded to a heavy-duty hinge kit rated for the saltier air that blows in from the baylands. We inspect post condition before quoting — call (628) 261-6223 for a free assessment.
A standard residential operator will likely fail prematurely in 94089. The salt-laden tule fog that rolls off the baylands accelerates PCB corrosion and rusts drive gears well ahead of their rated lifespan — a pattern local technicians recognize immediately because the salt-air exposure there behaves more like a coastal city than an inland Valley suburb just a few miles south. We spec sealed DC operators and marine-grade hardware for 94089 properties as standard, not as an upsell. Call (628) 261-6223 and we’ll recommend equipment rated for your specific microclimate.
Powder-coated aluminum outperforms bare steel long-term throughout Sunnyvale, and it’s especially critical in the northern ZIPs. Even in drier southern neighborhoods like 94086 and 94087, our persistently damp marine air promotes rust on uncoated steel. Wrought-iron style aluminum gives the aesthetic homeowners want for upgraded streetscapes and ADU-matched entries without the maintenance cycle. For commercial properties, galvanized steel with epoxy coating is the minimum we’d recommend.
Sometimes — but we need to evaluate safety compliance first. Early sectional gates often lack photoelectric sensors, edge sensors, or the structural integrity to handle modern operator torque. We can retrofit safety hardware to some legacy gates, but others require structural reinforcement or full replacement to meet current UL 325 standards. Steven will inspect the gate’s condition, track alignment, and spring balance before recommending operator compatibility. Call (628) 261-6223 to schedule — estimates are free.
We typically recommend a double swing or single sliding aluminum gate with dual-access automation — remote for the main residence, keypad or fob for ADU tenants. In 94087, we also plan for the post condition: original 1960s footings rarely handle modern automated loads, so we core new footings with galvanized posts as standard. Matching the gate style to your ADU architecture — modern flat-top, traditional wrought-iron scroll, or horizontal slat — keeps the streetscape cohesive and protects resale value. Call (628) 261-6223 and we’ll walk the property with you.
