We’ve been repairing and rebuilding gates in the San Fernando Valley since 1984, and Northridge has its own particular set of problems we’ve come to know well. The 1994 earthquake did more than crack walls here. It created a generation of gates that are now, all at once, reaching the end of their service life. We’ll get into exactly what that means for your driveway below, but the short version is this: if your gate was rebuilt between 1994 and 1998, the hinges, posts, and operator are likely due for attention about now.
Why Ironworks Gate Co. Is Northridge’s Preferred Gate Parts & Welding Company
Victor Salinas founded this company on a simple standard: the 400th job gets the same care as the first. That’s not a slogan. It’s the reason Northridge homeowners call us back when a different gate, on a different side of the house, starts acting up. Our technicians are background-checked and uniformed, and they work in your driveway the way they would work in their own mother’s. No shortcuts on the weld, no reusing a hinge that should have been replaced, no leaving the job until the gate opens and closes the way it should.
Northridge is not a one-size-fits-all service area. The tract homes off Reseda Boulevard, the ranch houses east of Balboa, the post-quake rebuilds along Devonshire and Nordhoff, they all have different gate hardware, different wall conditions, and different failure patterns. We’ve worked in 91324, 91325, and 91327 long enough to know what holds up on this ground and what doesn’t. That local knowledge means fewer return trips and fewer surprises on the invoice.
Our Gate Parts & Welding team handles the full scope: hinge replacement, post replacement, rail repair, custom welding, gate rollers, and latch and lock work. Every completed job is covered by our written 90-Day Done Right Promise. If it’s not right, we come back and make it right. No paperwork, no arguing.
Our Gate Parts & Welding Services in Northridge
Hinge Replacement
On a Northridge swing gate, hinges are almost never the root cause of a sag, but they’re always the first casualty. When the CMU pilaster shifts, the hinge takes the load and the pin starts to seize. We replace failed hinges with stainless hardware that can handle the movement, and we re-hang the panel so it clears the latch by a proper margin. On a 1960s ranch in Northridge, that often means correcting thirty years of someone just lifting the gate over a dragging latch rather than fixing the geometry.

Post Replacement
Post replacement in Northridge is as much about the footing as the post. Concrete block pilasters built in the 1960s and patched after the ’94 quake often have cracked footings that let the post lean a few degrees before the gate even notices. We cut out the old post, pour a new footing, set the post true, and re-hang the gate. Done once, done for the next several decades. A typical post replacement with footing runs $380-$900 depending on access and wall condition.

Rail Repair
Slide gates in Northridge tend to fail at the rail first. The San Fernando Valley’s summer heat expands the steel frame enough to bind against the track, and that repeated binding stresses the rail welds and the rack and pinion. We repair and re-weld rails, straighten bent sections, and reset the roller path so the gate moves without fighting the track. If the rack teeth are worn, we replace the rack section rather than patching it, because a worn rack will chew through a new pinion in a season.

Custom Welding
Not every gate problem calls for a manufactured part. Some Northridge gates are original ironwork from the 1950s and 1960s, and the right fix is a custom weld matching the original profile. We do argon-shielded MIG and TIG work on site, cut out cracked sections, and weld in new material that can be ground and painted to disappear. Custom welding runs $180-$600 depending on the extent of the repair, and we always show you the break before we start and explain what we’re doing and why.

Trusted Brands We Service in Northridge

We also service and repair Elite, Mighty Mule, and FAAC systems, among others. Because we carry common parts for these brands on the truck, most repairs in Northridge are completed in a single visit, without waiting on a parts delivery from a distributor across town.
Common Gate Parts & Welding Problems We See in Northridge Homes
- Shifted CMU pilasters throwing swing gates out of square. The post-quake patios and driveways in Northridge have pilasters that move with seismic activity and Valley heat. A hinge replacement on a post that’s still shifting won’t hold alignment for a year, so we check the post before we touch the hinge.
- Mid-1990s LiftMaster operators failing en masse. The original loop detectors and control boards from the ’94-’98 rebuild are at end of life now. Many of these units were installed before Knox key switches were strictly enforced, and a repair call often reveals a non-compliant opener that must be brought up to code before we can legally reinstall the automated system.
- Summer heat binding slide gates. Steel frames expand enough at 105°F to bind against tracks set in cooler weather. That binding stresses the rack and pinion teeth, and over time the rollers wear flat spots that make the problem worse.
- Rust at the weld joints on painted steel gates. The prolonged dry heat in Northridge accelerates oxidation on unpainted iron hardware, but the welds are the first place paint fails. We grind, treat, re-weld if needed, and re-coat with a finish that can hold up in this climate.

We were called to a 1962 ranch on Vanalden Avenue in 91324 where the original steel swing gate had sagged hard onto the latch post after the ’94 rebuild. The hinge post had shifted in its footing, the bottom hinge was seized, and the panel was still straight, so we re-poured the post footing, replaced both hinges with stainless, and re-hung the gate to clear the latch by half an inch. That’s the work, and it’s the kind of work we do every week in Northridge.

FAQs - Gate Parts & Welding in Northridge
The gates rebuilt after the ’94 Northridge earthquake are now 25-30 years old, and the hinge posts, rack and pinion systems, and operators installed in that wave are reaching end of service life at the same time. The original footings were poured quickly, the hardware was mid-1990s steel, and Valley heat and seismic movement have been working on both for three decades. If your gate was rebuilt in that window, expect hinge post and rack work sooner rather than later. Call (925) 590-4289 and we’ll assess yours before it fails outright.
Yes, LA County fire code requires automated gates serving residential driveways to have a Knox key switch or approved emergency-access system, and many Northridge gates rebuilt after the ’94 quake predate strict enforcement. If your opener doesn’t have one, we’ll add it before we complete the reinstallation, because we can’t legally leave a gate automated without emergency access. If your gate was automated in the 1990s, plan on this being part of the job.
Steel expands when the Valley hits 105-110°F, and that expansion is enough to bind a slide gate against a track that was set in cooler weather. The binding stresses the rack and pinion teeth, wears flat spots in the rollers, and can crack rail welds over time. The fix is resetting the track and roller path to account for thermal movement, then replacing any rollers or rack teeth that have already been chewed up. Call (925) 590-4289 and we’ll put a set of eyes on the track before the next heat wave.
For Northridge, galvanized steel is the better base material. We’re far enough inland that salt air isn’t the main enemy; the prolonged dry heat and sun exposure are. Galvanized steel handles UV and heat cycling better than painted steel, and it doesn’t lift and peel at the welds the way paint does. For structural parts like posts, rails, and hinge plates, galvanized with a powder coat on top is the specification we recommend for this climate.
The bottom hinge fails first. When a concrete block pilaster shifts, the bottom hinge takes the full cantilever load of the gate, and the pin seizes before the post shows obvious lean. That’s why we always check the hinge before the post: a seized pin tells us the pilaster has moved, even if the wall looks straight. Fix the post footing first, then the hinge, and the gate will hold. Skip the footing, and you’ll be replacing the hinge again inside a year.
