Most standard driveway gate installs on the west side of town run $2,800 to $5,500, while the heavy 20-foot-plus farm gates along Balfour Road and east of Highway 4 typically land between $6,500 and $11,000. If you’re in Brentwood and need a gate planned, priced, and installed without drama, call (213) 322-0062 and we’ll give you a written number before anything gets ordered. We know this town’s soil, wind, and lot sizes, and we build gates that stay square through all three.
Why Portcullis Gate Repair Los Angeles Is Brentwood’s Preferred Gate Installation Company
Brentwood homeowners keep our number because we show up when we say we will and we put the price in writing before the first post hole gets dug. The people calling us have usually had a bad experience already: a crew that ghosted, a quote that doubled mid-job, or a gate that sagged within a year. Our 365-Day Done Right Promise answers that directly. If the installation fails inside the guarantee period, we come back and fix it at no charge. That promise is stamped on every invoice, not muttered over the phone.
Every technician who arrives in Brentwood is background-checked and in uniform. You’ll know the name and face of the person at your gate before the truck turns down your street. And the person answering the phone when you call is a live human, 24 hours a day, including weekends and holidays. No callback queues. No voicemail tree. Dean Prescott, who runs our crew, has spent years dialing in how gates behave on Brentwood’s clay soil, and that matters more here than a glossy sales pitch.
We’re an independently owned Kingswell company, held to the same four promises every Kingswell location makes: a written price before work starts, a real arrival window, a clean job site, and a written guarantee. We’re not the cheapest option in Brentwood and we don’t try to be. We’re the one that stands behind the work in writing.
Styles & brands we work with




Automatic Gate Installation in Brentwood
Automatic gate installation in Brentwood means matching the operator to the actual weight and wind load of the gate, not just bolting on whatever’s on the truck. On the eastern side of town, where properties run one to five acres and driveways stretch hundreds of feet, that means spec’ing heavier-duty operators than a standard neighborhood gate would need. A swing gate operator swap on a Brentwood home typically runs $900 to $2,400 parts and labor, while a full automatic slide gate installation lands between $5,500 and $11,000. The difference comes down to post footings, power runs, and whether we use solar or mains electricity.
Long Driveway Power Solutions
Running conduit 300 feet down a Balfour Road driveway is expensive and often unnecessary. Solar gate openers with battery backup are common on Brentwood acreage, sized to handle winter fog and short charging days. We spec the panel and battery stack based on your gate’s cycles per day, not a generic kit.
Heavy-Duty Operators for Wide Gates
A 20-foot farm gate catches the Delta breeze like a sail. Undersized operators burn out, usually within a year or two. We install rack and pinion drives on slide gates and heavier-duty rams on swing gates, matched to the gate’s actual weight plus a wind-load margin that generic installers ignore.
Gate Installation Services in Brentwood
Gate installation services in Brentwood cover everything from a pedestrian gate on a side yard to a double swing gate across a main driveway to a 24-foot sliding steel gate on a horse property. Most new driveway gate installations run $2,800 to $7,500 depending on width and material, and double gates on wide rural entrances go up from there. We give you the full number, written down, before any hardware gets ordered. You approve it first.
Slide Gates for Rural Parcels
Slide gates are the smarter choice on flat Brentwood lots with long setbacks. They don’t fight wind the way swing gates do, and they don’t need the enormous hinge-post footings that clay soil demands. We install cantilever and V-track slide gates, both sized for the specific span and weight of your gate.

Solar-Ready Farm and Ranch Gates
For properties east of Highway 4 without easy mains access, solar makes sense. We install solar panels, battery banks, and keypad or remote entry systems so you can open the gate from a tractor or truck without getting out. Every solar system we build is sized to Brentwood’s actual winter daylight hours, not a San Diego spec sheet.

AfterCommon Gate Installation Problems We See in Brentwood Homes
- Clay soil heaving gate posts. Brentwood’s expansive clay swells in winter and shrinks in summer, which can shift a hinge post enough to bind a swing gate within a year of installation. We set footings below the expansion zone and use concrete pour methods that resist that movement.
- Undersized operators on wide farm gates. East of Highway 4, a 20-foot steel gate catching the Delta breeze can overload an operator that was sized for a suburban driveway. Burned-out motors and stripped gears are the usual result.
- Solar batteries dying in winter fog. Short December days and morning fog mean solar panels undercharge. If the battery bank wasn’t sized for Brentwood’s actual winter conditions, the gate goes dead exactly when you need it for livestock feeding.
- Sagging on long unsupported spans. The same breeze that cools Brentwood in summer pushes wide farm gates sideways enough to pop guide rollers off the track. We add support wheels and heavier rack systems to keep these gates running true.

FAQs About Gate Installation in Brentwood
A gate post footing in Brentwood needs to go at least 30 to 36 inches deep, and for wide gates we go 42 inches or more to get below the clay expansion zone. Shallow footings fail here because the soil heaves, and the gate binds. If you’re planning a heavy gate on a long driveway, call (213) 322-0062 and we’ll spec the footing depth for your exact soil and gate weight.
Yes. We regularly install solar-powered slide gates on Balfour Road properties where running mains power 300 to 500 feet down the driveway would cost more than the gate itself. The key is sizing the panel and battery for Brentwood’s short winter days and fog, which we do specifically rather than using a generic kit. Call (213) 322-0062 for a site assessment and written solar spec.
High summer temperatures cause hydraulic fluid to thin and electronic components to run hot, which makes undersized operators fail faster. In Brentwood, where July and August routinely hit the high 90s, this is a common failure mode, especially on motors that were already at their weight limit. Call (213) 322-0062 and we’ll tell you whether your operator can handle Brentwood’s heat or needs an upgrade.
A loop detector is strongly recommended for any automatic gate in Brentwood that sees real traffic, because it senses vehicles and prevents the gate from closing on a car or trailer. On rural parcels where you’re moving tractors or horse trailers through the gate, a loop detector is worth the extra cost. We include loop detector wiring on most automatic installs and we’ll explain whether your specific driveway needs one.
Wide farm gates sag because the unsupported end carries weight with no counterbalance, and the Delta breeze pushes the gate sideways, popping guide rollers. We prevent this by adding support wheels, specifying heavier rack and pinion drives on slide gates, and using cantilever designs where the gate never drags on the ground. Call (213) 322-0062 and we’ll assess your gate span and wind exposure, then give you a written fix.
