AfterFast, Reliable Gate Repair Across San Mateo
Gate repair in San Mateo usually falls into two camps: a gate that won’t latch, or an automatic opener that won’t move. Most repairs we handle in San Mateo run between $140 and $480, and you’ll see the exact number in writing before we touch anything. We’re the Gate Repair team from Latch & Post, part of the Cedarwell family, and we’ve worked on gates in Shoreview, North Shoreview, Baywood, Aragon, and the San Mateo Highlands since 2009. If your gate is stuck, sagging, or rusted through near the bay, call (626) 649-4572 and a live person answers – day or night.
Why Latch & Post Gate Repair Is San Mateo’s Preferred Gate Repair Company
San Mateo homeowners call us because we show up with shoe covers, drop cloths, and a written price – and because we know what bay air does to gate hardware. The marine layer off the bay keeps neighborhoods like Shoreview and North Shoreview damp for hours each morning. That moisture works into zinc-plated hinges, strike plates, and operator motor housings and starts rust you can see within a single winter. We spec stainless or marine-grade powder-coated hardware as a baseline here, not an upgrade.
Our technicians are background-checked, uniformed, and factory-trained on LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. The crew that arrives at your San Mateo home follows the Cedarwell C.A.R.E. values: we Clean up like it’s our own home, Ask before we move or touch anything, Respect your family’s time and quiet hours, and Explain the price before the work. That means drop cloths on your floors before we set a toolbox down, and a photo of the cleanup before we leave. Every repair is backed by our 365-Day Done Right Promise. If it isn’t right, we make it right – no argument, no fine print.
Wrought Iron Gate Repair in San Mateo
Wrought iron gate repair in San Mateo most often means addressing rust, broken welds, and hinge posts that have begun to lean in sandy bay-side soil. The salt in the air along the eastern edge of San Mateo attacks iron aggressively; a gate that looked fine in September can show flaking rust and a seized hinge by February. Most wrought iron repairs in San Mateo run $180-$520 depending on whether we’re replacing a single hinge plate or cutting out and re-welding a rusted bottom rail. You’ll get the written number before any work starts.
Rust repair and re-welding
When a wrought iron gate develops rust that has eaten through the metal, we cut out the compromised section, weld in new stock, grind the joint smooth, and apply a marine-grade primer and topcoat rated for salt exposure. For bayfront homes in 94401 and 94403, we recommend a powder-coat finish over standard paint. It costs a little more up front but lasts three to four times longer this close to the water.
Hinge replacement on leaning posts
San Mateo’s sandy soil near the bay lets gate posts drift, especially on older ranch homes where footings were poured shallow in the 1950s and 1960s. We excavate around the post, pour a deeper concrete footing, and set the post plumb before mounting stainless hinge hardware. A post that has shifted more than an inch usually can’t be shimmed back; the footing has to be redone.
Metal Gate Repair in San Mateo
Metal gate repair in San Mateo covers steel and aluminum driveway gates, side-yard gates, and the heavy slide gates we see on acreage entrances in the western hills and along the bayfront. The job usually involves straightening a sagging leaf, replacing seized rollers, refitting the latch and strike, or freeing a chain-drive that has bound up with rust and debris. Metal gate repairs in San Mateo typically run $160-$440 for standard driveway gates; larger slide gates on heavy posts can push toward $600-$900 when we’re replacing roller assemblies and realigning track.
Gate realignment and sag correction
Every metal gate eventually sags. The top hinge carries more weight than it was meant to, the frame flexes, and the latch stops meeting the strike plate. We correct this by re-hanging the leaf, reinforcing the top rail if it’s bowed, and adjusting the hinges so the gate swings square and closes without dragging. On San Mateo homes with sloped driveways – common in the Highlands – we also account for grade when setting the swing arc.
Weld and rust repair for steel gates
Steel gates within a mile of the bay rust faster than the same gate in San Carlos or Belmont. We grind off the rust, treat the metal, and weld reinforcement plates where the rust has thinned the steel. Then we seal and repaint. For North Shoreview and Shoreview homes, we use a marine-grade coating as standard – the salt air will find bare steel quickly otherwise.
Trusted Brands We Service in San Mateo
We service and repair operators from LiftMaster, FAAC, BFT, and Linear – the brands most common on San Mateo driveway and acreage gates – along with Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. We keep common control boards, remotes, safety photocells, and limit switches for these systems stocked locally, so a repair in San Mateo rarely waits on a part order. If your operator is from a brand you don’t recognize, call us anyway; we’ll identify it and give you a straight answer on parts availability and cost.
Common Gate Repair Problems We See in San Mateo Homes
- Bayfront salt corrosion: In Shoreview and North Shoreview, zinc-plated hinges and operator motor housings show surface rust within a year. We replace them with stainless or marine-grade powder-coated hardware so the repair holds.
- Wet-winter wood swelling: Homes built in the 1950s through 1970s often still have original wood gate panels. Rainy-season moisture makes the panels swell, bind against the post, and overload automatic operators not sized for that extra resistance.
- Sagging gates on sloped lots: The San Mateo Highlands neighborhood has steep driveways where gate posts shift gradually downhill. Swing gates on these lots need regular hinge adjustment and occasional post re-setting.
- Solar opener failures on acreage entrances: Hillside and bay-edge properties running solar gate openers often have undersized panels and batteries. The marine layer cuts solar production enough that a heavy farm-grade slide gate won’t cycle reliably on overcast days.

FAQs About Gate Repair in San Mateo
The marine layer that sits over eastern San Mateo deposits fine salt particulate on exposed metal every morning, and the humidity keeps that salt active for hours. Zinc-plated hardware from a hardware store will rust within a single winter in Shoreview or North Shoreview, while the same part in Belmont or San Carlos might last three to five years. That’s why we spec stainless or marine-grade powder-coated hardware as standard for bayfront zip codes. Call (626) 649-4572 and we’ll tell you exactly what your gate needs and what it will cost in writing.
The wood panel absorbs rainy-season moisture, expands, and binds against the hinge post or strike plate. That resistance overloads the operator, which is why an opener that worked fine in September will trip its safety limiter or jam mid-travel in January. The fix is usually a combination of planing or re-hanging the panel, freeing the hinge, and sometimes upgrading the operator to handle the extra wet-season resistance. We’ll diagnose it on site and give you the written price before we start.
Yes, but only if the panel is sized for marine-layer days and the battery bank can carry the gate through overcast stretches. Most solar gate failures we see on San Mateo hillside properties come from panels that were sized for full sun, not for morning fog cutting production by half or more. We calculate panel output against actual fog patterns for your location, then match the battery capacity to the weight of a heavy farm-grade slide gate. Call (626) 649-4572 for a free site assessment and a written quote.
Sag correction means re-hanging the gate leaf so it swings square and stops dragging or failing to latch. We remove the leaf, inspect the hinge post for lean, pour a deeper footing if the post has shifted, replace worn hinges, reinforce a bowed top rail, and re-set the gate so the latch and strike meet cleanly. On sloped San Mateo lots we also adjust the swing arc for grade. Most sag corrections run $220-$480, quoted in writing before any work starts.
Yes. We’re factory-trained on LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule, and we keep common replacement parts for these systems stocked locally. If your operator is an older FAAC or BFT unit, we can usually source the control board or limit switch within a day or two. Call (626) 649-4572 with your model number and a live person will talk you through what we’re likely to need.
We were called out to a wide swing gate in the North Shoreview area where the wood panel had swollen after a rainy season and the LiftMaster operator would jam mid-travel. The customer needed twice-daily livestock access for their goats out toward the eastern bay edge. We pulled the seized operator motor housing, replaced the rusted hinge plate with marine-grade hardware, poured a deeper post footing, and re-leveled the gate. Two seasons later the gate is still swinging cleanly, and we set the safety photocell for reliable daily cycling.
That’s the kind of repair that keeps San Mateo gates working through salt air, wet winters, and sloped lots. If your gate is sticking, sagging, or refusing to open, call us at (626) 649-4572. A live person answers around the clock, and your estimate is free. We’ll give you the written price, protect your floors, and leave with a photo of the cleanup. Every job is backed by our 365-Day Done Right Promise.
