We know Sunnyvale. The ranch homes off Remington Drive, the corporate campuses near Moffett Field, the townhome communities along El Camino Real. We’ve worked in 94086, 94087, 94085, and 94089 long enough to know which gate hardware survives here and which doesn’t. Call (877) 610-2993 and you’ll get a live person. Hal Gatewood answers the phone himself most days.

Why Gatewood Fence & Gate Is Sunnyvale’s Preferred Gate Installation Company
We’re not a national chain. We’re a locally owned, owner-operated shop, and Hal Gatewood’s name is on the business and on every invoice. The same person you shake hands with is the person who shows up to your house in Sunnyvale. We’ve been fixing and installing gates since 2001, and we’ve worked in enough Sunnyvale neighborhoods to know that a gate on a 1960s ranch home in 94087 needs different hardware than one on a 2005 townhome complex gate in 94085.
Sunnyvale homeowners call us because we repair before we replace. That’s not a slogan. Hal has welded broken hinge mounts and rebuilt sagging posts in driveways across 94086 rather than selling a whole new gate when a repair would outlast it. When a new gate is the right call, we’ll tell you that too, and the price won’t change after we shake on it.
We’re also one of the only shops serving Sunnyvale that stocks parts locally for LiftMaster, Viking, Ghost Controls, DoorKing, Elite, FAAC, BFT, Linear, and Mighty Mule. That means we’re not waiting a week for a hinge or a board to ship from somewhere else. We serve Sunnyvale from our San Francisco Bay Area office, and a live person answers our phone 24/7. No voicemail, no call tree, no chatbot.
Our Gate Installation Services in Sunnyvale
Every installation gets measured, quoted, and scheduled properly. We don’t promise same-day installs because a gate done right needs a solid post, a level gate, and hardware rated for this climate. What we do promise is a free measure and a written price before you commit. For more detail on the full scope of our work, see Gate Installation.
Swing Gate Installation
Swing gates are common across Sunnyvale’s 94086 and 94087 ranch-home neighborhoods, where side yards and driveways were gated during the 1980s and 90s security upgrades. The mistake we see over and over is a post set too shallow or a non-galvanized post put straight into soil that gets soggy in wet winters. In northern Sunnyvale near the baylands, an untreated post will rust through at the buried end within five to seven years. We spec galvanized posts, stainless hinge hardware, and deeper footings from day one.
Sliding Gate Installation
Sliding gates are the standard on Sunnyvale’s newer townhome and condo complexes, especially in 94085 and 94089, and on commercial properties near Moffett Field. A slide gate lives or dies by its track, rollers, and operator. Where bay-salt air comes into play, a cheap galvanized track will pit and seize. We run sealed rollers and marine-grade hardware on any slide gate within a mile of the baylands. For anything automated on an HOA entry, we also handle the low-voltage side correctly: loop detectors, photocells, edge sensors.
Security Gate Installation
For Sunnyvale business owners and homeowners wanting a gate that actually keeps someone out, a decorative gate isn’t the answer. We build and install security gates with reinforced frames, proper latching, and operators matched to the gate weight. In the Moffett corridor, we’ve seen 1990s slide-gate operators where the drive chain seized from salt air at the same time the in-ground loop detector degraded beyond repair. That’s a compound failure that takes a crew who understands both the mechanical and electrical sides. We’re that crew.
Pedestrian Gate Installation
A pedestrian gate on a Sunnyvale home has to handle daily use without sagging or dragging. We install them with stainless hinge pins and galvanized frames, especially on the older ranch homes where the original gate was redwood on mild steel hardware. Redwood swells through Sunnyvale’s wet winters and shrinks hard in summer, which is why we set hinges on standoff plates and use threaded-through bolts, not screws into the post face.

Trusted Brands We Service in Sunnyvale
We’re certified to service and install nine major gate brands. For Sunnyvale customers, that usually means LiftMaster operators on residential driveways, DoorKing or Viking on commercial slide gates near Moffett Field, and Ghost Controls on lighter pedestrian and farm-style gates. We keep brand-matched brackets, hinges, and operator boards stocked locally, so we don’t make you wait on a slow supply chain. If you already have an operator you like and the gate itself is failing, we’ll set the new gate to match your existing bolt pattern whenever possible.
Common Gate Installation Problems We See in Sunnyvale Homes
- Sagging swing gates on older ranch homes: The hinge post rots at the buried end, often within a decade, and the gate drops until it won’t latch. This is the single most common failure we see in 94086 and 94087. The fix is a new galvanized post set deeper than the original, not another shim under the latch.
- Seized slide-gate tracks near the baylands: In 94089, salt air off the South Bay pits cheap galvanized tracks and chains. Gate rollers lock up, the operator overheats, and the gate stops midway. We spec sealed rollers and marine-grade chains within a mile of the bay.
- Warped redwood planks pulling hinge screws loose: Sunnyvale’s wet winters and bone-dry summers cause planks on 25 to 40-year-old gates to swell and shrink repeatedly until screws strip out of the post. New planks alone don’t fix it. The post and hinge hardware need attention too.
- Failed in-ground vehicle loop detectors on commercial gates: In the Moffett business-park corridor, we routinely find loop detectors that no longer sense a car pulling up. That’s almost always a corroded connection or a cut wire at the saw line. It kills the gate’s automatic response, and it needs low-voltage diagnosis, not just mechanical work.
At a 94086 ranch home off Remington Drive, our crew pulled a 30-year-old decorative iron swing gate whose hinge post had rotted at the buried end. The gate had sagged a full inch at the latch. We set a new galvanized post in a deeper footing, swapped in stainless hinge pins, and matched LiftMaster operator brackets to the original bolt pattern so the homeowner kept her early-90s operator without re-wiring. That’s the difference between a crew that understands Sunnyvale’s older housing stock and one that just sells you a new gate.
Pricing for Gate Installation in Sunnyvale, CA
Here’s what you should expect to pay for gate installation in Sunnyvale:
| Gate Type | Typical Sunnyvale Price Range |
|---|---|
| Pedestrian gate (painted steel or redwood, no automation) | $1,800 - $3,400 |

What moves the price in Sunnyvale is post depth and hardware grade. A galvanized post set to spec for bayland soil costs more up front than a cheap powder-coated post that rusts through in six years. You pay for the post once and forget it. The alternative is paying again when the gate sags. Every job is quoted before work starts. You agree to the number before we dig the first hole.

FAQs - Gate Installation in Sunnyvale
Your gate is sitting in salt-laden air off the South Bay baylands, and your friend’s gate isn’t. The salt accelerates rust on the buried end of your hinge post, and once the post rots below grade, the gate drops. Cupertino sits farther from the bay and gets far less of that marine air. The fix is a galvanized post set in a deeper footing with stainless hinge hardware, not a third shim under the latch. Call (877) 610-2993 for a free measure and we’ll tell you exactly what’s under your gate post.
Yes, in most cases we can reuse your LiftMaster operator if it’s still in good working condition. We’ll match the bracket bolt pattern on the new gate to your existing operator so you don’t rip out wiring or buy a new motor. The operator usually isn’t the problem on those older 94086 gates. The post and hinges are. We quote the gate and the operator work separately, and the price is agreed before anything starts.
The most common hidden failure is a compound one: the drive chain seizes from bay-salt corrosion at the same time the in-ground vehicle loop detector degrades and stops sensing cars. You’ll see the gate move sluggishly first, then fail to open when a car pulls up. That takes a crew who handles both mechanical and low-voltage diagnosis on the same call. We’ve been doing exactly that in the 94089 corridor for years. Call (877) 610-2993 and describe what the gate is doing. We’ll tell you straight whether it’s the chain, the loop, or both.
Look at where the gate sits relative to the latch. If the gap at the latch has widened over the past year or the gate scrapes the ground when it swings, your post is moving. Planks don’t cause a gate to drop at the latch. The post footings on 1980s gates in 94087 were often set too shallow and never galvanized. If the gate has sagged more than half an inch, you need the post pulled and a new galvanized one set deeper. If it’s just cupped or cracked planks on a solid post, planks alone are fine. We’ll tell you which one you have with a free look.
Yes. Any automated gate in Sunnyvale must have a working entrapment protection system. For slide gates, that means a minimum of two external photocells. For swing gates, it means photocells plus edge sensors on the moving leaves. These requirements come from UL 325, which California enforces. If your existing gate opener doesn’t have working safety sensors, we won’t tie a new gate into it without bringing it up to code. That’s not an upsell. It’s a safety requirement with real liability attached. Call (877) 610-2993 and we’ll verify what you have and quote the correction honestly.
