Fast, Reliable Gate Parts & Welding Across Fairfax
Gate parts and welding in Fairfax typically runs $280–$650 for most repairs, with same-day response available throughout the 94930 and 94978 ZIP codes. We’re familiar with the steep hillside lots off Broadway, the redwood-shaded properties up toward the ridge, and the moisture problems that keep our phone busy from October through April.
We’ve been driving out to Fairfax for years. The town’s bowl-shaped valley traps Pacific moisture and channels it inland, which means your gate hardware deals with conditions that San Rafael or Kentfield properties simply don’t face at the same intensity. David and his team carry the welding equipment, replacement posts, heavy-duty hinges, and automation parts needed to fix structural gate failures on-site, usually in a single trip. That’s the difference between a gate-only specialist and someone who has to order parts and come back. Call (833) 805-4890 for a free estimate.
Why Ironwood Gate Repair Los Angeles Is Fairfax’s Preferred Gate Parts & Welding Company
Fairfax homeowners call us because we’ve earned 233 verified reviews at a 4.7-star rating across our service territory, and many of those come from repeat customers in Marin County who’ve watched us diagnose problems that previous contractors missed. David Kaplan serves as both Owner and Field Supervisor, which means the person with final accountability shows up at your property, not a rotating crew with a checklist.
Our response time to Fairfax is typically same-day or next-day, depending on whether we’re already working in the San Anselmo or San Rafael area. We know the local conditions: the clay-heavy hillside soil that heaves seasonally, the original redwood gates installed on 1920s through 1960s homes, and the way moisture gets trapped under the dense canopy of mature oaks and redwoods that keeps wood wet far longer than in neighboring towns.
We’re exclusively gates. That focus means we stock the heavy-duty hardware, welding equipment, and automation components specific to gate systems, not a general truck with whatever was available at the supply house that morning.
Our Gate Parts & Welding Services in Fairfax
Post Replacement
Post replacement is our most frequent call in Fairfax, and there’s a specific reason why. The town’s valley geography produces some of the highest rainfall in the Bay Area, roughly 40+ inches annually, and the mature tree canopy keeps soil saturated against gate posts for months. On a steep lot off Broadway, we replaced a rotted redwood post on a heavy double gate that had been sagging for months, the owner had serviced the hinges twice but missed the post rot hidden by the dense canopy. We used a heavy-duty LiftMaster pneumatic opener and a custom-welded steel bracket to handle the oversized door and the hillside slope, all in one trip.
A typical post replacement in Fairfax runs $450–$780, including removal of the rotted post, concrete work suited to clay-heavy hillside soil, and installation of a pressure-treated or steel post depending on the gate weight and your preference. Posts on uphill lots require deeper setting and often custom welding for bracket alignment.
Custom Welding
Custom welding solves problems that off-the-shelf hardware can’t touch. Fairfax’s older homes on sloped lots frequently have gates that were built to fit irregular openings, not standardized dimensions. When a hinge tears out of a rotted post or a rail bends from years of sagging, we fabricate brackets, reinforce rails, and build mounting plates on-site.
Most custom welding jobs in Fairfax fall between $320–$680, depending on material thickness and whether we’re reinforcing an existing structure or building new. We weld steel, not aluminum, for gate applications, because the loads on a heavy redwood gate demand it.
Hinge Replacement
Hinge replacement in Fairfax often reveals the real problem: not the hinge itself, but the post it’s mounted to, or the gate frame that has twisted from years of operating out of plumb. The seasonal soil heave on hillside properties throws gates off alignment steadily, and if you just swap the hinge without checking the geometry, you’ll be calling someone again in six months.
We charge $180–$340 for standard hinge replacement on residential gates, including adjustment of gate swing and latch alignment. For heavy double gates or commercial-grade hardware on acreage properties, expect $380–$520.
Rail Repair
Rail repair addresses the horizontal members that keep your gate square. Moisture damage in Fairfax doesn’t just attack posts; it works into end-grain on rails where water wicks in and the wood swells, cracks, or pulls fasteners. We splice, sister, or replace rails, and weld steel reinforcement where the gate has sagged beyond what wood alone can recover.
Rail repair typically runs $280–$490 in the Fairfax market.

Trusted Brands We Service in Fairfax
We work on your brand. Our Gate Parts & Welding team carries parts and programming capability for Linear, Viking, Ghost Controls, and DoorKing systems commonly found on Fairfax’s larger properties and acreage gates. We don’t tell you your system “isn’t supported” and try to sell you a full replacement. David and his team have 14 years of field experience across nine major automation brands, so we diagnose the actual failure, whether it’s a motor, a control board, a safety sensor, or a welded structural component that’s letting the whole system drift out of spec.
Common Gate Parts & Welding Problems We See in Fairfax Homes
- Post rot at ground level from months of wet clay soil contact. The above-grade wood often looks sound while the base has turned to pulp. A technician who only inspects the visible post will miss this until the gate collapses.
- Wood panel swelling and binding in the wet season. Redwood gates under the shaded canopy absorb moisture and expand, then bind against posts or the ground until the drier months shrink them back. The cycle repeats yearly, stressing hinges and hardware.
- Hidden hinge misalignment from seasonal soil heave on hillside lots. Gates that were plumb when installed gradually drift out of square as clay soil swells in winter saturation and contracts in summer. The hinge bolts loosen, the gate sags, and the latch quits catching.
- Corroded metal hardware from persistent fog drip. Even galvanized hardware degrades faster under redwood canopy conditions than in sun-exposed installations. We see seized rollers, pitted latch mechanisms, and hinge pins frozen in their barrels.

What moves the price: gate weight and size, hillside access and slope, whether the post is set in concrete that must be excavated, and whether automation components need reprogramming after structural repair. We don’t quote over the phone for post replacement without photos, because we’ve learned that what looks like a hinge problem from a description is often post rot hidden at grade. Estimates are free.

FAQs — Gate Parts & Welding in Fairfax
Fairfax’s bowl-shaped valley traps Pacific moisture and produces roughly 40+ inches of annual rainfall, while the dense redwood and oak canopy keeps soil saturated against posts for months after the rain stops. This sustained moisture contact rots wood at ground level even when the visible post above grade looks fine. Neighboring towns with more sun exposure or better drainage simply don’t see the same rate of hidden post failure. If your gate is sagging and you’ve already replaced hinges, the post base is the likely culprit. Call (833) 805-4890 for a free inspection.
Yes. Binding after rain usually means wood swelling, hinge misalignment from soil heave, or both. We diagnose whether the gate frame is square, whether hinges need relocation or upgrade to heavy-duty hardware, and whether the post itself has shifted. For Fairfax’s wet-season conditions, we often recommend steel reinforcement or custom-welded brackets that maintain alignment through seasonal ground movement. Call (833) 805-4890 to schedule before the next storm cycle makes it worse.
Yes, and hillside post replacement is specifically something we handle regularly in Fairfax. The clay-heavy soil on sloped lots heaves seasonally, so we set posts deeper and use concrete footings rated for that movement. We also weld custom brackets when needed to compensate for grade changes that throw standard hardware out of alignment. Most hillside post replacements in Fairfax run $520–$780 depending on access and excavation requirements. Call (833) 805-4890 for an exact quote.
We service and stock parts for Linear, Viking, and DoorKing systems commonly specified for heavy swing and slide gates on larger Fairfax properties. David and his team are factory-trained or field-proven across nine major brands, so we don’t limit you to one manufacturer’s ecosystem. If your existing opener can be repaired or needs replacement with compatible heavy-duty hardware, we’ll tell you straight and handle the programming on-site. Call (833) 805-4890 with your brand and model.
Yes. We fabricate steel brackets on-site to reinforce torn hinge mounts, redirect load on sagging frames, or adapt standard hardware to non-standard gate dimensions. Custom welding for hinge-related sagging typically runs $320–$520 in Fairfax, including the bracket fabrication and installation. This is usually faster and stronger than ordering an uncertain aftermarket part. Call (833) 805-4890 to have David assess whether welding or full hinge replacement is the right fix.
