AfterDoorKing Gate Installation in Tarzana: What to Know First
DoorKing gate installation in Tarzana typically runs $1,800 to $4,600 for a complete driveway gate package, and most jobs are done within five to seven business days after measurements are confirmed. If you already own the DoorKing operator and just need it mounted, wired, and dialed in, you’re looking at $600 to $1,400. We’re an independent DoorKing service provider, not a factory-authorized shop, which means we work for you, not a warranty quota.
This page is for Tarzana homeowners who own a DoorKing swing or slide operator, or who want one installed, and who’d rather talk to a real person than scroll through spec sheets. Call (818) 514-7606 and Hal Gatewood or one of his crew will pick up.
How DoorKing Products Fail - and How We Fix Them
DoorKing builds a solid operator, but after enough years in Tarzana’s dry heat and high-wind canyons, certain things wear out in predictable ways. These are the ones we see most:
- DoorKing 9150 (swing gate): clutch slipping after 5-8 years. The 9150 uses an internal clutch to protect the arm, and in Tarzana’s fine dust, that clutch face wears smooth. The symptom is a gate that opens fine in the morning but drifts or stops mid-travel by afternoon. We pull the operator, clean the clutch assembly, and replace the friction disc. Most outfits want to sell you a new operator. $90 in parts usually fixes it.
- DoorKing 1601/1602 (slide gate): drive chain stretch and idler pulley wear. These workhorses go on hundreds of Tarzana commercial and residential properties, but the chain tensioner has a narrow adjustment window. Once the chain stretches past that window, the gate hunts and shudders. We measure the chain, replace it with OEM-gauge steel, and align the idler sprocket so it tracks straight. Installing a new gate on a stretched chain is throwing money away.
- DoorKing 6003/6004 (swing gate, heavy duty): limit switch drift. The mechanical limit switch design is simple and reliable, but vibration from windy conditions off the Santa Monica Mountains will make it creep over time. The gate slams at the close, or stops an inch short and reverses. We reset the limits and add a locking collar so it stays put.
- DoorKing MicroCLIK transmitters: desync after power flickers. This isn’t an installation issue per se, but it shows up during every install. Homeowners assume the new gate is wired wrong because the remote won’t pair. In reality, DIP-switch-era DoorKing remotes reset to a default code set when the control board loses power for more than a few seconds. We set the resident’s code into the new board and verify all remotes before we leave.
- DoorKing 9050/9100: magnetic lock (maglock) wiring corrosion. Any DoorKing pedestrian gate with a maglock needs a properly sealed power run. In Tarzana, where sprinkler overspray and canyon humidity mix, we see corroded terminals inside the junction box within three years of a handyman installation. We re-terminate with sealed connectors and move the junction box out of the spray path. The gate doesn’t fail; the splice does.
Our DoorKing Gate Installation Process
Every DoorKing job follows the same steps, whether it’s a fresh driveway gate install or replacing an operator that gave up. Here’s how it works:
- 1
You call, a person answers. Hal or one of his crew picks up at (818) 514-7606. You describe the gate, the operator, and what it’s doing. We give you a straight answer about whether we can help.
- 2
We come out and measure. We check post depth, gate weight, travel distance, and the existing power run. For a new install, we confirm concrete work and conduit routing. For an operator replacement, we determine whether the arm or chain drive matches the gate’s swing direction and weight rating.
- 3
We make the parts decision with you. For DoorKing operators, we recommend OEM internal components (clutch, board, limit switches) because aftermarket internals don’t hold tolerance. For brackets, posts, and chain, domestic aftermarket steel is usually fine and costs less. We tell you the difference and let you decide.
- 4
We do the work on site. Hal welds on site. He does not haul your gate to a shop. Posts get set in concrete, the operator gets mounted with proper standoffs, wiring is run in sealed conduit, and the gate is hung, balanced, and adjusted.
- 5
We test it hard. Open, close, stall, obstruct, reverse. We simulate a wind gust, a kid running through, a power blip. If the gate hesitates or the safety edge has a dead spot, we address it before we pack up.
- 6
You get the guarantee in writing. Every job carries the 90-Day Done Right Promise. If it’s not done right, we make it right. One call brings us back. No runaround.
What DoorKing Gate Installation Costs in Tarzana
Here’s what we charge for common DoorKing work in Tarzana. These are the numbers we quote over the phone, and they hold unless we find something structural when we open things up. If the scope changes, we stop and call you first. The price is agreed before any work starts.
- DoorKing operator installation only (you have the operator, gate, and power): $600-$1,400 depending on swing vs. slide and the amount of conduit work.
- DoorKing 9150 heavy-duty swing operator, installed (operator included): $2,100-$2,800
- DoorKing 1602 slide operator, installed (operator included): $2,300-$3,100
- Complete driveway gate package (steel gate, DoorKing operator, posts, concrete, safety edges, remotes): $1,800-$4,600, with the biggest variables being gate size, post depth, and whether we’re working on a slope.
- DoorKing board replacement (9150/9100 control board): $520-$780 parts and labor.
What moves the price: gate weight (a 14-foot steel driveway gate weighs more than a 6-foot pedestrian gate), slope grade, access to a power source, and whether we’re removing an old gate or starting fresh. Estimates are free. Call (818) 514-7606 and we’ll give you a real number, not a range with a question mark.
Why Tarzana Homeowners Call Gatewood Fence & Gate for DoorKing Work
Hal Gatewood has been fixing gates in Tarzana since 2001, and most of his customers live within a few miles of Ventura Boulevard. Some have been calling him back for going on two decades. That matters when you’re standing in your driveway looking at a gate that won’t close and wondering who’s going to show up and whether they’ll actually fix it. Hal’s name is on the shop, the address is published, and the license number is on every invoice. The 90-Day Done Right Promise is stamped in writing on every job, not buried in fine print.
We also know DoorKing isn’t the only brand in the neighborhood. We service LiftMaster, Mighty Mule, and Ghost Controls regularly, which means when a Tarzana homeowner has a mixed setup (a DoorKing operator with a LiftMaster safety edge, for example), we don’t scratch our heads. We fix it. And because we weld on site, the gate stays in your driveway where you can watch the work happen.
Hal grew up not far from the Tarzana Recreation Center and still catches breakfast at a diner on Reseda most Saturdays. That’s not a marketing line. That’s the accountability of living where you work.
FAQs
Yes, we do this all the time in Tarzana. We survey the gate’s weight, post condition, and hinge points to confirm the operator’s rated capacity matches. If the gate sags or the hinges are worn, we address that first, because hanging a new operator on a failing gate is a waste of your money. Call (818) 514-7606 for a free estimate.
For internal components like the control board, limit switches, and clutch assembly, we use genuine DoorKing parts. Aftermarket internals don’t hold the same tolerances, and a board failure on a $4,000 gate installation isn’t worth saving $80. For brackets, posts, chain, and gate hardware, we use quality domestic steel that matches or exceeds the original spec. We always tell you which is which and why before we order anything.
A straight operator replacement on an existing gate takes one visit, usually four to six hours. A complete driveway gate package with new posts and concrete takes five to seven business days from measurement to final test, with one to two days of on-site work. We don’t rush concrete cure times, and we don’t leave a gate with posts that are still green.
Usually it’s either a stretched chain on a slide operator or worn hinges on a swing gate. If the gate was installed by someone who didn’t align the drive chain or balance the gate properly, the motor works harder than it should and the whole assembly vibrates. We realign, balance, and adjust until the gate rolls or swings quietly. That’s the standard, not the exception.
Yes. Every DoorKing gate installation we do includes a properly sealed power run in conduit, wired to code, with the safety edges and photo eyes connected and tested. We don’t leave the job until the gate reverses on obstruction and the safety edge responds across its entire run. If a power outlet doesn’t exist where the operator mounts, we’ll run the line or coordinate with a licensed electrician we trust.
If you’re in Tarzana and your DoorKing gate needs work, call (818) 514-7606. A live person answers, day or night. Hand me your number and I’ll call you when I’m on my way, none of that four-hour window stuff.
