We’re Gate Repair - San Mateo, part of the Cedarwell family of gate specialists. We focus on one trade: gates. The latch that holds them and the post that carries them. For San Mateo homeowners, that focus matters because the bayfront salt air and the hillside grades here punish generic hardware faster than almost anywhere else on the Peninsula.
Why Latch & Post Gate Repair Is San Mateo’s Preferred Gate Installation Company
Most of the gate work we do in San Mateo comes from neighbors talking to neighbors. A family in Baywood gets a new driveway gate installed, the crew leaves the driveway cleaner than they found it, and the next call comes from two doors down. That’s how we’ve built our reputation here since 2009. We’re not a general handyman outfit. We’re not a big-box installer. We’re gate people, and every technician who shows up at a San Mateo home is background-checked, uniformed, and factory-trained on the equipment you’ll actually find in this city: Linear operators on mid-century ranch side gates, Ghost Controls solar units on hillside properties, DoorKing and Viking heavy-duty operators on long bayfront driveways.
San Mateo customers also tell us they appreciate what we don’t do. We don’t leave a mess. Every visit includes shoe covers and drop cloths before we step inside, plus a photo of the cleanup before we leave. We don’t surprise you on price. The written estimate comes before the work, not after. And if something isn’t right, the 365-Day Done Right Promise covers it. No argument, no fine print.
Gate Installation Services in San Mateo
Gate Installation Services in San Mateo covers everything from a new pedestrian gate at the side yard to a wide double swing gate across a driveway. The job starts with a site walk. We check the post footings, the grade, the hinge load, and whether the existing posts can carry a new gate or need to be replaced. Then we quote you a number in writing. For a standard wood or aluminum pedestrian gate in a flat San Mateo neighborhood, plan on $1,200 to $2,800. A full driveway gate installation, with posts, panels, hardware, and finish, typically lands between $3,500 and $7,500 in this market.
Driveway and Double Gates
A double driveway gate in San Mateo handles two opposing forces: the daily open-and-close cycle and the marine air off the bay. We spec marine-grade powder-coated aluminum or sealed cedar, with stainless hinges as the baseline. Not as an upgrade. As the starting point. That’s the difference between a gate that looks good for two winters and one that still swings true five years out.
Pedestrian Gates and Hardware
Side-yard pedestrian gates in San Mateo’s ranch-home stock are often 40 to 60 years old, with original zinc hardware that has been rusting quietly. When we hang a new one, we reset the post in concrete where needed and build the latch side to survive Shoreview humidity. The finished gate should close with one hand, not a shoulder bump.

Electric Gate Installation in San Mateo
Electric Gate Installation in San Mateo means adding an automatic operator to a new or existing gate, and it’s the part where local conditions matter most. A standard single-swing operator installation on a flat lot runs $1,200 to $2,200. A heavy-duty sliding gate operator for a wide driveway, or a solar-powered system on a hillside parcel, runs $2,500 to $4,200 depending on span, weight, and power access. Every quote is written, agreed, and signed before the first hole is dug.
Solar-Powered Operators for Hillside Parcels
In the San Mateo Highlands, running a 120-volt line down a long driveway can cost more than the operator itself. Solar makes more sense. We recently installed a solar gate opener on a hillside parcel off a long rural driveway there, where trenching for mains power wasn’t practical. Our tech set deeper post footings to handle the grade shift, paired a Ghost Controls solar opener with a LiftMaster operator, and added a loop detector and safety photocell so livestock and vehicles could pass safely. The gate opens reliably now, no trenching, no power bill.
Heavy-Duty Operators for Wide Gates
A 16-foot farm gate on a sloped Highlands lot is a different animal than a 6-foot pedestrian gate in Shoreview. The operator has to fight gravity, wind, and the extra weight of a wide swing panel. We size the motor for the actual load, not the brochure load, and we build the post footings deep enough that the gate doesn’t sag into the hill over time.
Trusted Brands We Service in San Mateo
We’re factory-trained on the brands San Mateo homes actually have: DoorKing, Viking, Ghost Controls, and Linear, along with LiftMaster, FAAC, BFT, Elite, and Mighty Mule. For San Mateo customers, that means faster diagnosis and the right part on the first visit, because we carry repair stock for the operators most common on the Peninsula rather than ordering everything from a distant warehouse. When your DoorKing slide operator goes down on a Wednesday morning, you want a tech who has seen a dozen of them that month.
Common Gate Installation Problems We See in San Mateo Homes
- Salt air rust on hinges and operator housings. In Shoreview and North Shoreview, standard zinc-plated hardware shows surface rust within a single winter. We install stainless or marine-grade powder-coated hardware from the start.
- Sloped-lot post shift in the Highlands. Gate posts on grades lean over time. When we set a new post, we go deeper than code minimum and brace against the hill so the gate doesn’t sag at the hinge side.
- Wooden gate panels that swell in winter rain. November through March, moisture soaks into older wood panels. The panel widens, the latch binds, and the automatic opener strains. We size the operator for wet-season weight, not dry August weight.
- Undersized operators on long rural driveways. A homeowner buys a “standard” opener kit and it burns out in a year because the gate is too heavy. We measure the actual panel weight and span, then spec the motor to match.

FAQs About Gate Installation in San Mateo
Yes. Solar-powered operators handle this directly, and they’re common on long hillside driveways in the San Mateo Highlands where trenching for mains power is impractical or expensive. We pair the solar panel with a battery system and a low-draw operator, then verify the charge load against the gate’s daily cycle count. Call (626) 649-4572 and we can tell you if your gate is a good solar candidate.
It’s the bay. Shoreview and North Shoreview sit directly on the water, and the marine layer deposits fine salt particulate on every exposed metal surface, every day. Standard zinc-plated hinges will show rust inside one winter season this close to the bay, which is why we install stainless-steel or marine-grade powder-coated hardware as the baseline in those neighborhoods. If your previous installer used hardware-store hinges, that’s the explanation.
It starts with footing work. A wide swing gate on a grade puts constant lateral force on the posts, so we dig deeper footings and let the concrete cure fully before hanging the gate. Then we size the operator to the actual panel weight, add a loop detector and photocell beam so vehicles and livestock don’t trip the gate into each other, and test the open-close cycle under load. Expect the job to take a full day or two, not an afternoon.
Yes. Under UL 325 and California access-control standards, every automatic gate operator must have a primary and secondary entrapment protection system, typically safety photocells and a reversing edge. We install and test every system before we leave, and that protection is included in our installation price. If your existing operator is missing those safety devices, we’ll tell you on the first visit.
We design the gate system around what has to pass through it, and what shouldn’t. That means loop detectors for vehicles, keypads or remotes for people, and swing speed and force settings low enough that a slow-moving animal can clear the gate safely. On rural parcels, we also factor in fence line conditions. A gate isn’t just a panel; it’s the weakest point in the whole perimeter.
