Why Portcullis Gate Repair Is San Lorenzo’s Preferred Gate Repair Company
San Lorenzo is different from every city around it, and we treat it that way. David D. Bohannon built nearly the entire community between 1944 and 1955, which means the gates, posts, hinges, and operator control boards on these properties are aging out at roughly the same time. A technician who has not worked this specific stock may swap a hinge and call it done, only for the sag to return when the undersized 1950s footing shifts again. Our team has seen that failure enough times to know the correction is usually at the base, not the panel.
We’re an independently owned Kingswell location, and every repair carries the four-part Kingswell Guarantee: a written price before work starts, a real arrival window, a clean job site, and a written guarantee on the repair. If the repair fails within 365 days, we return and correct it at no charge under the 365-Day Done Right Promise. Dean Prescott leads our San Lorenzo service area, and the people answering the phone at (940) 412-7340 are the same ones scheduling your technician, 24 hours a day including holidays.
Gate Welding in San Lorenzo
Gate welding in San Lorenzo is the most common structural repair we perform on Bohannon-era homes because the original 1950s tubular steel and light wrought iron were never built to survive seventy years of bay air. We cut out rotted or rusted-through sections, weld in new steel, grind the joints clean, and repaint with a rust-inhibiting primer matched to the gate’s finish. Most localized rust repair and section welding runs $220 to $475, while re-welding a broken hinge bracket or reinforcing a post base typically falls between $180 and $340.
When Welding Beats Replacing
If the frame steel still rings true and only a lower corner or a hinge mount has rotted, welding is almost always cheaper than a full gate replacement. We’ve saved dozens of San Lorenzo gates this way. But if the top rail is rusted through in multiple places or the pickets are paper-thin at the base, replacement is the honest call and we’ll say so plainly.
Post Footing Repair
We weld in new post stubs and set them into deeper concrete when the original 1950s footing has heaved, especially near San Lorenzo Creek where flood-moisture intrusion destabilizes bases. This runs $260 to $520 per post, and it’s the fix that keeps the gate from sagging again two months later.
Commercial Gate Repair in San Lorenzo
Commercial gate repair in San Lorenzo spans sliding gates on Hesperian Boulevard shop yards, swing gates at apartment complexes off Bockman Road, and outdated operator systems at industrial parcels near the railroad corridor. The work typically means swapping out failed actuators, repairing broken chain drives on slide gates, realigning track wheels, and upgrading obsolete control boards to meet current UL 325 entrapment standards. Most commercial service calls in San Lorenzo run $340 to $1,900 depending on whether we’re repairing or retrofitting.
Operators and Control Boards
Commercial operators in San Lorenzo include a steady mix of Viking, LiftMaster, and DoorKing units, many installed years ago and now failing on boards you can no longer buy. When a board is obsolete, we tell you the retrofit cost against the replacement cost so you’re choosing with real numbers, not a shop-tech guess.
Since 2008, a Written Standard
Portcullis Gate Repair has operated as a Kingswell company since 2008, and every commercial job in San Lorenzo gets the same written guarantee as a residential call. If a slide gate operator we installed fails inside the first year, the return visit is free, the parts are covered, and it’s written on the invoice before we leave.
Trusted Brands We Service in San Lorenzo
We carry service experience across nine major gate-operator brands, and our San Lorenzo crews regularly work on FAAC swing-arm actuators, BFT slide-gate motors, Linear control boards, and Viking hydraulic operators on commercial sites. Parts for these systems are stocked at our Bay Area dispatch office, which means fewer multi-day waits for San Lorenzo customers. When a Legacy-era Linear board fails, we can usually quote the retrofit same-day at the curb.
Common Gate Repair Problems We See in San Lorenzo Homes
- Sagging timber and steel swing gates. The original 1950s footings under many Bohannon ranch homes were poured too shallow for the gate weight, and any soil movement near the San Lorenzo Creek corridor makes the hinge post lean. The gate starts dragging, and the fix has to start at the base or it comes back.
- Obsolete operator control boards. Legacy LiftMaster, Linear, and Viking boards from the 1990s and early 2000s are no longer manufactured, and there’s no direct swap part. We quote the retrofit path: new board, new safety edges where required, and current UL 325 photocell protection.
- Bay-air rust in 1950s hardware. The marine layer that sits over San Lorenzo keeps mild salt in the air year-round, and lightweight tubular steel from the 1940s and 1950s oxidizes faster than newer hot-dipped steel. Pivot hinges seize, and frame sections can rust through from the inside while looking fine on the street side.
- Unpermitted gate work from previous owners. Because San Lorenzo is unincorporated Alameda County, gate and fence permits run through the Alameda County Planning Department, not a city hall. We regularly walk homeowners through what’s retroactive, what needs a permit, and what falls under normal repair.

FAQs About Gate Repair in San Lorenzo
Most hinge, latch, and operator repairs in San Lorenzo do not require a permit because they’re maintenance, not structural change. But because San Lorenzo is unincorporated Alameda County, any gate work that alters the footprint, adds a new post footing, or changes the gate height runs through the Alameda County Planning Department rather than a city building department. We handle the paperwork path for you and tell you before the job starts whether a permit applies. Call (940) 412-7340 and we’ll check your specific setup.
Most sagging Bohannon-era gates in San Lorenzo can be fixed, because the frame steel is usually still solid and the real problem is the original undersized concrete footing under the hinge post. The repair is a deeper footing, a corrected hinge post, and modern adjustable hinges, which runs $260 to $520. Replacement is only the right call when the frame itself is rusted through or the gate was built too light for the operator that’s on it. We’ll show you the steel before you decide.
San Lorenzo sits in a low East Bay pocket near the bay shore and along San Lorenzo Creek, so the marine layer keeps mild salt-laden air on the metal year-round. That accelerates oxidation on operator housings, hinge pins, and control-board contacts in a way inland cities like Livermore simply don’t see. Add the uniform 1944-1955 housing age, and you get operators failing from corrosion and obsolescence at the same time, which is why we stock retrofit parts for these units locally.
You can usually retrofit a modern operator onto a sound older gate, and in San Lorenzo that’s often the smarter money. We’ve retrofitted LiftMaster operators onto original Bohannon-era tubular steel gates by correcting the hinge post first, then adding a modern swing-arm actuator with current UL 325 safety photocells. The retrofit runs $900 to $1,800 when the gate and posts are structurally sound. If the gate needs welding or a new post footing, that’s additional and quoted separately before any work starts.
Yes. We repair and retrofit commercial gates across San Lorenzo, including slide gates, swing gates, truck yard gates, and automated entry systems. We service LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule operators, and we quote written pricing on every commercial job. Call (940) 412-7340 for a free estimate, and we’ll give you the price before any work begins.
