Gate Repair in San Mateo, CA
Gate repair in San Mateo typically runs $180 to $650 depending on whether the job involves a hinge replacement, motor repair, or structural welding, and most calls are completed same day. The real difference here is the environment: the marine layer off the Bay keeps hardware damp through long morning stretches, and salt air attacks uncoated iron faster than in inland Peninsula cities. Homes built in the 1950s through 1970s dominate San Mateo’s housing stock, which means most gates we see have already outlived their original hardware by twenty years. Call (833) 754-7503 and a live person picks up, 24 hours a day.
Why San Mateo Homes Are Different
San Mateo sits in a narrow corridor where the marine layer rolls in off the Bay and lingers until midday most of the year. That damp, salt-laden air settles on gate hardware and starts working the moment the sun drops. In the eastern ZIP codes, 94404 and 94401, the exposure is direct and relentless. We see hinge pins rusted to half their original diameter, operator housings with corroded seams, and control boards failed from salt creep on the circuit traces. The fill land under Mariners Island wicks groundwater upward into concrete post footings, corroding buried hardware from below while the salt air attacks from above.
Gate Repair in San Mateo
Ironworks Gate Co. handles gate repair across San Mateo from Baywood to Mariners Island, and most jobs are completed in a single visit. We carry parts for nine automation brands and weld custom hardware on-site, so a repair that would take another company two trips gets finished before we leave. Whether it is a rusted hinge pin on a 1960s ranch gate near El Camino Real or a failed operator on a Mariners Island townhome, we settle the price before turning a single bolt.

Rust Treatment
San Mateo’s marine layer keeps gate hardware damp through long morning stretches most of the year, and the salt air off the Bay accelerates corrosion on uncoated ferrous metal far faster than in inland Peninsula cities. In the 94404 and 94401 ZIP codes, we regularly see iron hinges and latches deteriorate within five years without proper protection. Our rust treatment strips corroded material, applies conversion coating, and finishes with marine-grade paint or powder coat suited to bay-adjacent exposure. Full gate preventive coating typically runs $250 to $450, and for HOA properties on Mariners Island this is not cosmetic work. It is the difference between a five-year gate and a twenty-year gate.
Hinge Repair
The 1950s to 1970s ranch-style homes that dominate San Mateo’s housing stock were built with wrought-iron swing gates now sixty to seventy years old. Original hinges fatigue, pins wear oval, and the salt-laden air seizes what grease cannot protect. A standard hinge replacement runs $180 to $280; custom fabrication for Craftsman or Spanish Colonial profiles in Baywood and San Mateo Park ranges $320 to $480. We fabricate replacement hinges on-site when off-the-shelf parts do not match the original geometry, and we spec stainless or marine-grade hardware for bay-adjacent installations.
Can you repair my gate the same day in San Mateo?
Most gate repairs in San Mateo are completed same day. We keep common hinge sizes, operator parts, and welding equipment on our trucks, and we dispatch to San Mateo from the Bay Area office with a standard 30 to 45 minute response across most of the city. Call (833) 754-7503 and we will tell you when we can be there.
Gate Installation in San Mateo
Gate installation in San Mateo runs $2,800 to $7,500 for most residential projects, with bayfront properties in 94404 typically landing at the higher end due to marine-grade hardware requirements. Most San Mateo installations are completed in one day once materials arrive. We measure, order, and schedule installations with a written price before any work starts. For a full breakdown of what we build, see our Gate Installation page.
Swing Gate Installation
Swing gates remain the most common type in San Mateo’s older neighborhoods. The 1950s to 1970s ranch homes throughout the 94401 and 94402 corridors were built with wrought-iron swing gates that matched the low, horizontal lines of the architecture. A standard single swing gate installation runs $2,800 to $4,200; double swing gates range $3,800 to $5,500. In Baywood, we have replaced pairs of 60-year-old gates with original strap hinges so rusted the leaves sagged into the driveway, fabricating custom stainless hinges to keep the vintage look.
Do I need HOA approval before installing a new gate in San Mateo?
Yes, most San Mateo HOAs, particularly on Mariners Island and in Baywood, require architectural review board approval for any visible gate modification. We provide detailed material specifications and finish samples with our written estimates to streamline your ARB application. Call (833) 754-7503 for a free measure and written price.
Gate Motor & Opener in San Mateo
Gate motor and opener repair in San Mateo typically costs $180 to $520 depending on the failure, and most jobs are completed same day. In bay-adjacent neighborhoods, salt air destroys standard opener control boards in 5 to 7 years, so we stock marine-grade replacements and sealed stainless components for homes from Baywood to Mariners Island. We service nine major brands, including FAAC, BFT, and Linear. For more on what we fix, see our Gate Motor & Opener page.
Motor Installation
New gate motor installation in San Mateo runs $680 to $1,850 for most residential swing and slide systems, with bayfront properties in 94404 typically landing in the upper range due to marine-grade component requirements. We spec stainless-steel operators with sealed control boxes for Mariners Island and the Bayshore corridor, where salt air attacks circuit boards from three sides. A gate on shifting bay-fill soil needs different anchoring than one on bedrock in the hills, and we measure gate weight, cycle count, and post stability before recommending any unit.
Why do gate openers fail faster on Mariners Island?
Mariners Island’s automatic gate operators fail in 5 to 7 years because salt air surrounds the unit on three sides, corroding motor windings and control board traces far faster than standard residential ratings allow. We specify marine-grade or stainless-component openers for these installations. Call (833) 754-7503 for an exact quote, estimates are free.
Gate Access Control in San Mateo
Gate access control repair and installation in San Mateo typically runs $450 to $2,800 depending on the system, and most jobs are completed in a single visit with upfront pricing settled before work begins. From keypads on Baywood estate gates to phone entry systems on downtown 94401 townhomes, we handle the full range. For a deeper look at access control options, see our Gate Access Control page.
Keypad Entry Systems
Keypads are the workhorse of San Mateo’s multi-family and HOA properties. We install and repair weather-sealed units built for the Bay climate, including marine-grade Viking keypads that withstand salt air exposure in 94404. A typical keypad installation in San Mateo runs $650 to $1,200 including programming, and we fabricate custom mounting brackets when standard hardware will not fit older post spacing.
Do you work with HOA townhome communities in San Mateo?
Yes. We regularly service HOA communities throughout San Mateo, particularly the dense townhome developments on Mariners Island and near the downtown Caltrain corridor. We understand HOA approval processes, coordinate with property managers, and can program rolling-code remotes for entire buildings. Call (833) 754-7503 for a free estimate.
Gate Parts & Welding in San Mateo
Gate parts and welding repair in San Mateo typically costs $180 to $650 depending on the component, and most jobs are completed in a single visit with upfront pricing settled before work begins. Bay-adjacent salt air takes a specific toll on gates in this city, and we stock the hardware to fix it. For more on what we fabricate, see our Gate Parts & Welding page.
Hinge Replacement
San Mateo’s mid-century wrought-iron gates were originally fitted with plain steel hinges that were never meant to survive six decades of marine layer exposure. In Baywood and San Mateo Park, we regularly see ornamental gates where the bottom hinge has rusted solid or sheared off entirely. A typical hinge replacement on a standard residential gate runs $180 to $340, using galvanized or stainless-steel ball-bearing hinges sized to the actual gate weight.
Can you match the original wrought-iron style on my 1950s San Mateo gate?
Yes, we regularly fabricate custom hinges, pickets, and scrollwork to match San Mateo’s mid-century ranch and estate gate designs. Our mobile welding equipment lets us shape and fit replacement components on-site, finished to match the original patina or paint. Call (833) 754-7503 and we will quote the approach before cutting metal.

What San Mateo Customers Say
"Our slide gate had been dragging for months and getting worse. The chain was stretched and a guide roller had seized. Both replaced, and he reset the limits so it stops properly at each end now."
- Veronica Ramirez"The repair is holding. He was quite a bit later than the window I was given and the office did not call me about it, I had to call them. The work itself was done well once he arrived."
- Ruben Morales"Control board fried after a lightning storm. He showed me the burn mark on it, quoted the board, and put a surge protector on the line so hopefully it does not happen again."
