Gate repair in Brentwood usually costs between $180 and $2,800 depending on whether we’re realigning a hinge post, replacing a control board, or swapping out a heavy operator on a 20-foot farm gate. Most repairs we schedule in Brentwood are done within one to three days, and we answer the phone live around the clock. If your gate is dragging on the driveway, stuck halfway open, or refusing to close at all, call us at (213) 322-0062 and we’ll give you a straight answer before we ever send a truck. We know Brentwood’s east side, the acreage along Balfour Road, and the neighborhoods west of Highway 4, and we’ve seen what clay soil and Delta wind do to gates out here.
Why Portcullis Gate Repair Los Angeles Is Brentwood’s Preferred Gate Repair Company
Brentwood homeowners call us because the problems here aren’t the problems you find in a dense city. We’re not resetting a pedestrian call box at a condo complex. We’re out on 2-acre parcels east of Highway 4 diagnosing why a 300-pound steel slide gate stalls halfway when the afternoon wind kicks up. Dean Prescott leads our Brentwood scheduling, and every crew that rolls into town carries the same written Kingswell Guarantee on every invoice: the price is written before any work starts, the arrival window is real, the job site is cleaned before we leave, and the repair is guaranteed in writing for 365 days. If the repair fails inside that year, we come back and fix it at no charge under the 365-Day Done Right Promise. That’s the Kingswell Way, and it applies at every independently owned Kingswell location.
Brentwood customers keep our number because they’ve already paid another gate company once for a fix that lasted six weeks. We get it. A written guarantee sounds old-fashioned, but it’s the reason people who try us once don’t go back to the no-show outfits. When you call, a live person answers. When we commit to a window, that’s the window. And when we hand you the invoice, the number on it matches the number we quoted before the first bolt came off.
Styles & brands we work with




Wood Gate Repair in Brentwood
Wood Gate Repair in Brentwood usually means a sagging, heavy driveway gate on a custom home where the original builder hung a solid cedar or redwood panel on hinges rated for something half the weight. We see it all over the 1990s and 2000s developments south of Balfour Road, and out east toward Marsh Creek Road where older ornamental gates are fighting against clay soil that moves every wet winter. A typical wood gate repair in Brentwood runs $220 to $650, depending on whether we’re replacing hinge hardware, adding a diagonal brace, or reinforcing the post footing. Some jobs are as simple as re-mortising a hinge. Some require us to pull the panel, straighten the frame, and re-hang it with heavier hardware.
Hinge and Post Failure on Heavy Wood Gates
A wood gate that drags on the latch side is usually not a wood problem at all. The post is leaning because the footing wasn’t deep enough for Brentwood’s expansive clay. We pull the post, drill a deeper footing below the soil’s active movement zone, and re-set it in concrete before re-hanging the gate. The gate panel itself often needs a sag cable or steel frame to stop it from parallelogramming.
Solar and Gate Operator Options for Wood Panels
Many Brentwood customers with wood driveway gates want to add an operator but don’t want to trench power across a 100-foot driveway. We install solar-openers with DC actuators that handle solid wood panels without drawing on the house panel. They work well as long as the gate is balanced first. If the hinges are still binding, no opener in the world will save it.
Driveway Gate Repair in Brentwood
Driveway Gate Repair in Brentwood covers everything from a 12-foot steel tube gate at a cul-de-sac entrance in the Shadow Lakes area to 20-foot wrought-iron slide gates on Balfour Road equestrian properties. Most driveway gate repairs here run $250 to $1,400. Replacing a failed operator is the biggest ticket item. Re-tracking a slide gate that’s jumped its guide rollers is the most common. If the gate is the only thing between a horse and Highway 4, we take the job seriously. If it’s the only thing between a teenager and a pool, same answer.
Slide Gate Track and Roller Work
Slide gates fail at the rollers first. A bent track, a worn guide roller, or a post that’s shifted half an inch will stop a 400-pound gate dead. We inspect the top guide, the roller trucks, and the end-stop, then replace what’s worn and re-align the track to the post. On windy days the Delta breeze works a long gate like a lever. If the post isn’t solid, the gate moves sideways and pops the rollers. That’s exactly what happened on a Balfour Road job a few weeks ago, where a 20-foot swing gate had worked its hinge post loose. We re-set the post deeper, straightened the panel, and moved the opener to a heavy-duty solar setup so the property no longer depends on grid power that blips out there regularly.
Operator Repair and Power Issues
Rural electrical service means surges. We replace a lot of fried control boards on older LiftMaster and FAAC units where a transformer blew down the road and sent a spike into the logic board. A board swap runs $280 to $550 including the part. If the operator is a 15-year-old Viking or Linear unit with an undersized motor for the gate it’s pushing, we’ll tell you honestly and price a replacement before we patch a motor that’s going to fail again.
Trusted Brands We Service in Brentwood
We service and stock parts for most operators you’ll find on Brentwood driveways: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. If we know which brand is on your property before we arrive, we bring the common failure parts for it on the truck. That’s why we ask when you call. We also handle a lot of Italian operators out here on the custom home side of town. FAAC and BFT units are everywhere on the larger estates east of Highway 4, and we keep their most common capacitors, limits, and arms in local stock. No week-long waits for a part to cross the Delta.
Common Gate Repair Problems We See in Brentwood Homes
- Swing gates dragging on the hinge side. Expansive clay soil pushes hinge posts out of plumb every wet winter. The gate starts fine in October and drags by February. We re-set the post with a deeper footing and add a sag correction to the panel.
- Operators failing after rural power surges. The electrical grid east of Highway 4 delivers some punishing fluctuations. Control boards on LiftMaster, FAAC, BFT, and Viking units take the hit. Repair means replacing the board and often adding a surge suppressor at the disconnect.
- Slide gates stopping partway when the wind picks up. The Delta breeze pushes a long panel sideways, tripping the safety photocells. It’s not always a sensor problem. Often the track has worn and the gate can drift enough to break the beam. We align the safety circuit and correct the mechanical drift.
- Wood gates with rot at the bottom rail. Brentwood’s hot dry summers and wet winters work on stained wood gates from both directions. We splice in new material, treat the cut ends, and re-hang with hardware that doesn’t trap moisture against the wood.

FAQs About Gate Repair in Brentwood
Brentwood’s expansive clay soil swells when wet and shrinks when dry, which slowly pushes gate posts out of plumb. The post leans, the hinge side drops, and the latch stops lining up. Repair means re-setting the post in a deeper footing below the active soil zone and adding a sag correction to the panel. Call (213) 322-0062 for an exact quote on your gate.
Yes. We install solar openers on farm and estate gates throughout the Balfour Road and Marsh Creek Road corridor. The system includes a panel, battery, DC actuator, and safety edges sized to the gate’s weight and span. We’ve done them on 20-foot gates where trenching power would cost more than the opener itself. Estimates are free.
Usually neither. The Delta breeze pushes the gate panel sideways, the panel drifts out of the safety beam path, and the controller interprets it as an obstruction. We align the safety circuit and correct the mechanical drift at the track so the gate tracks true even in a strong afternoon wind. If the board is also damaged, we’ll show you before we replace anything.
We recommend adding contact safety edges and photo eyes to any automated gate on an equestrian parcel in Brentwood. A gate that reverses on contact rather than crushing against the stop is non-negotiable when animals are involved. We can also add a separate pedestrian gate so you don’t have to cycle the full 20-foot panel every time someone walks through. Call us to walk through the options.
A sagging panel that drags before it reaches the latch, or a hinge post out of plumb from clay soil movement. Both are common in Brentwood. The fix is usually a deeper post footing plus a sag cable or steel brace on the panel. We’ll measure the drift, show you what we found, and give you a written price before any work begins.
