We’ve been crossing the Peninsula to serve San Mateo homeowners since 1984.

If you’re ready to talk specifics, call (866) 977-5773. A live person answers, day or night.
Why Ironworks Gate Co. of San Jose Is San Mateo’s Preferred Gate Installation Company
San Mateo homeowners don’t call us for quick fixes. They call us for gate repair - San Mateo done right, so it closes like the day it was hung, ten years from now. Our reputation here was built slowly, one job at a time, starting with the older ranch homes in Beresford and Fiesta Gardens where original wrought-iron gates from the 1950s finally needed honest replacement.
We carry a strong local reputation across San Mateo County, with homeowners in Hillsborough and Belmont regularly referring us to neighbors. Reviews from San Mateo customers consistently mention our technicians arriving on time, explaining the work plainly, and leaving the driveway cleaner than they found it. Our response time to San Mateo averages under an hour for emergencies, and we schedule standard installations within three to five business days.
What separates us from general contractors and handymen is simple: we only do gates. That means our trucks carry marine-grade stainless hardware for bayfront corrosion, stepped hinge brackets for hillside grades, and the automation inventory to complete most installations without a second trip. We’re not figuring it out as we go. We’ve already seen what San Mateo’s soil, salt air, and architecture do to gates, and we build for it.
Our Gate Installation Services in San Mateo
Swing Gate Installation
Swing gates remain the most common choice for San Mateo homes, and for good reason. They suit the Peninsula’s traditional aesthetic, they’re straightforward to automate, and they work well on the flat lots common in Hayward Park and the central neighborhoods. But a swing gate is only as good as its posts and hinges, and in San Mateo, that means accounting for things other installers miss.
In the bayfront 94404 zone, compressible bay-mud soil causes gradual gate-post tilting and misalignment. We’ve replaced too many gates where standard 24-inch concrete footings shifted within two years, leaving the gate dragging or the latch misaligned. Our San Mateo swing gate installations use deeper, engineered footings with expanded bases or helical piers where soil conditions demand it. The gate swings free. The latch catches clean. And it stays that way.
For hillside properties in 94402 near Beresford or the western slopes, we fabricate stepped hinge brackets that maintain plumb alignment on graded approaches. We installed a custom redwood carriage-house swing gate on a sloped lot in the 94402 hillside neighborhood near Beresford, fitting a Ghost Controls automatic opener with a whisper-quiet DC motor and integrating it with the homeowner’s smart-home system via Z-Wave. The gate required stepped hinge brackets to account for the grade, and we used marine-grade stainless steel hardware throughout to resist bay-area salt corrosion.

Sliding Gate Installation
Sliding gates make sense for San Mateo driveways with limited swing clearance, steep approaches, or homeowners who simply prefer the clean line of a gate that disappears along the fence. They’re also the most forgiving of imperfect grades, provided the track and rollers are specified correctly.
We see two critical failure points in San Mateo sliding gates: inadequate posts that tilt under the cantilevered load, and standard steel rollers that seize after a single wet season in salt air. Our installations use galvanized steel or aluminum track systems with sealed, stainless-steel bearing rollers rated for marine environments. The gate rolls smooth. It doesn’t groan or shudder. And the homeowner doesn’t call us back in eighteen months with a gate stuck half-open.
For automated sliding gates, we’re equipped across nine brands including FAAC and Linear, with the inventory to match your existing automation or specify new. Most sliding gate installations in San Mateo are operational the same day we hang them.

Security Gate Installation
San Mateo’s larger estate properties, particularly in the hillside 94402 zip and the custom homes near Hillsborough’s border, increasingly request San Mateo Gate Access Control with video intercom and smart-home connectivity. This is specialized work that demands both metal craft and certified automation expertise.
Our Gate Installation team designs security gates around your actual security needs, not a generic template. That might mean a pedestrian gate with keypad and cellular intercom for a bayfront townhouse in Mariners Island, or a full estate entry with loop detectors, safety edges, and integration with a Lutron or Control4 system for a hillside property. We specify the automation, fabricate or source the gate, and handle the integration. One contractor, one warranty, one call if anything needs adjustment.

Pedestrian Gate Installation
The side-yard pedestrian gate is often an afterthought in San Mateo, until it sags, drags, or won’t latch. We treat these as seriously as any driveway gate, because for daily use, they’re the gate you interact with most. Our pedestrian gate installations match or complement your main gate in material and finish, with hardware specified for the same local conditions: marine-grade stainless for bayfront properties, proper sealing and hardware for wood gates in humid western neighborhoods.

Common Gate Installation Problems We See in San Mateo Homes
- Gate posts set in standard concrete footings tilt within two years due to gradual subsidence on bay-mud soil in 94404. We see this pattern repeatedly in the Mariners Island and bay-fill developments. The gate itself is fine. The posts are fine. The soil beneath them is not. Our solution is engineered footings designed for the substrate, not hope.
- Wooden gates in western hillside neighborhoods (94402) warp and crack from humidity cycling and lack of proper sealant on exposed end grains. San Mateo’s marine layer keeps humidity elevated enough that untreated wood absorbs and releases moisture year-round. We specify cedar or redwood with factory-sealed end grains, or engineered composite materials where the homeowner wants zero maintenance.
- Automated opener housings and hinge hardware pit and fail prematurely from salt-laden marine air in eastern zip codes if not specified with marine-grade coatings. Standard powder-coated steel looks fine at installation. In 94404, it doesn’t look fine for long. We specify anodized aluminum, hot-dip galvanized, or 316 stainless hardware for any gate within two miles of the bay.
- Sloped driveways in hillside neighborhoods force improper gate geometry, causing binding and premature operator strain. A swing gate hung level on a sloped approach either scrapes the driveway at the low side or gaps at the high side. Our stepped hinge brackets and custom-fabricated frames correct the geometry without visible compromise.

FAQs - Gate Installation in San Mateo
Bay-mud soil in 94404 compresses and shifts gradually, tilting standard concrete footings out of plumb. We use deeper, engineered footings with expanded bases or helical piers to anchor below the unstable layer. If your posts are already tilting, call (866) 977-5773 - we can evaluate whether the posts can be reset or need full replacement with proper foundations.
Marine-grade 316 stainless steel or hot-dip galvanized hinges with sealed bearings outperform standard powder-coated steel in San Mateo’s salt-laden eastern neighborhoods. We specify these as standard for any property within two miles of the bay. Call (866) 977-5773 and we’ll confirm what’s on your current gate and whether it’s suited to your location.
Yes. We regularly integrate gate openers with Z-Wave, Control4, Lutron, and other smart-home platforms, including the Z-Wave integration we completed for a hillside Beresford property with a Ghost Controls whisper-quiet DC motor. Integration complexity depends on your existing hub and desired features. Call (866) 977-5773 to discuss your specific system.
Untreated or improperly sealed wood absorbs moisture from San Mateo’s persistent marine-layer humidity, then releases it in dry spells, causing cyclic warping. End grains are especially vulnerable. We specify factory-sealed cedar or redwood, or engineered composites, and we never leave end grain exposed. For a free evaluation of your current gate, call (866) 977-5773.
Yes. A standard swing gate hung level will scrape or gap on a grade. We fabricate stepped hinge brackets and custom gate frames that maintain proper geometry without visible compromise. Sloped installations are common in 94402 hillside neighborhoods and require precise field measurement. Call (866) 977-5773 to schedule a site evaluation - estimates are free.
