AfterFast, Reliable Gate Installation Across San Dimas
A new driveway gate in San Dimas usually costs between $2,800 and $9,500 installed, depending on whether you need a single swing gate for a standard ranch home or a heavy 18-foot double swing gate built for horse trailers on an equestrian lot. We’re Gatewood Fence & Gate, and Hal Gatewood has been running this shop since 2001 with the same promise on every job: if it’s not done right, we make it right, in writing. Most San Dimas installs take one to two days once materials are on site, and we’ll give you a straight price before any work starts. Call (877) 610-2993 and you’ll get a live person, not a voicemail.
Why Gatewood Fence & Gate Is San Dimas’s Preferred Gate Installation Company
San Dimas is a different kind of market than the surrounding valley towns, and we treat it that way. The equestrian zoning in the northern foothills means we’re not just hanging a standard 12-foot gate on a cul-de-sac lot. We’re installing gates that have to clear a 16-foot horse trailer, swing over uneven gravel, and hold up to Santa Ana winds that come screaming down through the mountain gaps. A gate that works fine in West Covina will fold under those loads within a season or two. Hal’s crew has been fixing exactly those failures for over two decades.
The 90-Day Done Right Promise sits on every invoice we hand out in San Dimas. One call brings us back. No runaround, no arguing about whose fault it is. Hal’s name is on the shop, the published address is easy to find, and the license number is right there for anyone who wants to look it up. That’s the oldest accountability there is. When you call, a live person picks up all day, every day. Not a call center three states away. Not a chatbot. You’ll talk to someone who knows what a sagging hinge post on a 1970s tubular steel gate looks like, because they’ve replaced hundreds of them.
Our Gate Installation Services in San Dimas
Swing Gate Installation
Swing gates are the most common install we do in San Dimas, especially in the 1960s and 1970s ranch neighborhoods south of the freeway. A single swing gate on two solid post footings will give you years of trouble-free service, but the key is what’s under the ground. San Dimas soil in the foothill tracts shifts with the wet-dry cycle, and posts set without proper depth and concrete will lean within a year. We set every post with the gate’s weight, wind load, and soil type in mind. For equestrian properties, a double swing gate gives you the widest clear opening for trailers and hay deliveries.
Sliding Gate Installation
On steep or uneven driveways, a sliding gate often makes more sense than a swing gate. San Dimas canyon roads and foothill properties frequently have drives that pitch up or down, and a swing gate that has to fight gravity every time it moves will wear out its hinges and operator fast. A cantilever sliding gate rides on a track and roller assembly that doesn’t care about the grade. We install slide gates from 10 feet up to 20 feet and beyond, with operators sized for high-cycle use. For ranch gates that open and close 50 times a day during riding season, a commercial-grade operator is not optional.
Pedestrian Gate Installation
A separate pedestrian gate next to a big driveway gate saves wear on the main operator and keeps horses from slipping through when you open the wide gate. We build and install matching pedestrian gates in the same material and finish, so the whole entry looks like it was planned, not bolted on later. In San Dimas neighborhoods where kids walk to school along the foothill paths, a properly latched pedestrian gate with a self-closing hinge is a real safety feature. We can match existing wrought-iron patterns or start fresh with powder-coated steel.
Double Gate Installation
Double gates are the workhorse of San Dimas equestrian properties. A pair of 9-foot leaves gives you an 18-foot clear opening, which is what a horse trailer with a wide-axle rig actually needs. But two leaves mean two posts, two hinge sets, and an operator that has to coordinate both sides through a full cycle without binding. When one leaf lags, the other takes all the torque and the hinges fail early. We set both posts in line, hang both leaves level, and install operators with enough torque to move both panels through a Santa Ana gust without overheating.

Trusted Brands We Service in San Dimas
We install and service operators from FAAC, BFT, Linear, and Viking, among others. San Dimas customers with equestrian properties need operators that can cycle repeatedly throughout the day, and these are the brands that hold up under that load. When we install a new gate or retrofit an old one, we carry common replacement parts for these systems on the truck, so a service call that turns into a parts replacement doesn’t drag into a second visit. If you have an existing operator from a brand we didn’t list, ask Hal directly. We service most major residential and light-commercial systems, plus a few older ones that most companies won’t touch anymore.
Common Gate Installation Problems We See in San Dimas Homes
- Old posts that look fine but are rusted through at the base. In San Dimas, hard San Gabriel Valley water migrates into post pockets and accelerates corrosion at ground level, where the metal meets the concrete. A new gate hung on an old post with a compromised base will sag within months. We check the post before the gate.
- Operators starving on long 120V runs from the house panel. Foothill equestrian lots often have the operator pedestal 200 feet or more from the panel. Voltage drop on those long runs kills motors prematurely, especially when the gate is wind-loaded. We test line voltage at the pedestal before blaming the operator.
- Gates hung before modern safety requirements existed. Most 1970s and 1980s San Dimas slide gates have no entrapment protection. If you’re installing a modern operator on an old slide gate, the system needs a safety photocell or edge sensor to meet UL 325. Otherwise the gate is a hazard around horses, kids, and trailers.
- Wind-bent posts and snapped welds from Santa Ana events. The foothill gaps above San Dimas funnel wind straight down the canyon roads. Gates that face those gusts need heavier posts, deeper footings, and weld points reinforced. A gate built for a flat valley lot will fail here.

On a ranch property off San Dimas Canyon Road in the northern foothill tracts, our crew replaced a 1970s-era tubular steel swing gate with a new 18-foot double swing gate on fresh post footings. The original hinge post had corroded at the base from hard San Gabriel Valley water and wind-driven Santa Ana gusts, and the old gate operator was running on a long 120V line that measured 14% voltage drop at the pedestal. We set new posts, upgraded to a LiftMaster commercial-grade operator with a dedicated circuit, and added a safety photocell and keypad entry for horse trailer access.

FAQs - Gate Installation in San Dimas
Most 1970s and 1980s posts in San Dimas equestrian areas are rusted at the base from hard water exposure and should be replaced with new posts set in proper footings. A new gate hung on an old post with a corroded base will sag within months. We inspect the post before quoting, and we’ll tell you straight if it’s reusable. Call (877) 610-2993 for a free inspection.
Often not, because the voltage drop on a 200-foot 120V run starves the motor, especially when wind loads the gate. We test line voltage at the pedestal first. In many San Dimas foothill installs, we run a dedicated circuit or size the operator for the actual voltage it’s receiving. Don’t guess; call us and we’ll test it.
Yes. A 16-foot gate panel weighs more than a standard 12-foot residential gate, and it cycles more often during riding season. You need a commercial-grade operator with a higher duty cycle rating. We install FAAC, BFT, Linear, and Viking operators sized for exactly this kind of San Dimas equestrian use. We’ll spec it based on gate weight, width, and daily cycles.
It depends on the gate’s condition. A slide gate from the 1980s with solid structure and a good track can usually be retrofitted with a safety photocell or edge sensor. A swing gate with rusted hinges, a bowed panel, or a failing operator base is usually cheaper to replace. We’ll tell you which one you’re looking at, and the quote won’t change when we get there.
Santa Ana winds funnel down the canyon gaps and hit foothill gates with sustained gusts that bend undersized posts, snap weak welds, and overheat operators that are already straining against the wind. San Dimas gate installations need heavier posts, deeper footings, and operators with enough torque reserve to move the gate through a gust without tripping thermal protection. We build for that wind because we’ve seen what it does to gates that weren’t.
