Why Liberty Gate Repair San Francisco Is Sebastopol’s Preferred Gate Parts & Welding Company
We’ve been working on gates for over 31 years, exclusively — not fences, not general construction, not “handyman specials.” That matters in Sebastopol, where the gate problems are different from Santa Rosa’s. The marine layer here, pushed through the Petaluma Gap, creates a moisture-driven repair environment we’ve learned to read like a local.
Our 613 customers have rated us 4.9 stars, and that pattern of consistency comes from showing up prepared. Steven Lee, our owner and lead technician, diagnoses it and fixes it — no dispatchers, no rotating crews unfamiliar with your FAAC or LiftMaster system. When you’re on a rural Sebastopol parcel with a heavy farm gate that’s sagging after the last atmospheric river, you want the person who answers the phone to be the person who welds the repair.
We stock parts and weld on-site. One trip. That’s the difference between a gate company and a contractor who “also does gates.”
Our Gate Parts & Welding Services in Sebastopol
Hinge Replacement
Sebastopol’s persistent fog — that daily marine layer the Petaluma Gap delivers — rusts ferrous hinges faster than inland Sonoma County climates allow. We replace corroded hinges with galvanized or stainless hardware rated for coastal moisture, and we weld custom mounting plates when the original bolt pattern has rotted out. On older redwood gates near the downtown core, we’ve learned to oversize hinge backers to distribute load across compromised wood.
Post Replacement
This is the big one in Sebastopol. Wood gate post bases rot from constant fog moisture, causing gate sag and misalignment within 5–7 years even with redwood. We replace rotted posts with pressure-treated or galvanized steel sleeved bases, and we weld custom post caps and hardware mounts in the same visit. On a rural parcel off Pleasant Hill Road, we replaced a failed FAAC 400 hydraulic arm and custom-welded a heavier-duty gate roller for a 12-foot redwood swing gate that had swollen from fog and rusted hinges. The homeowner wanted a one-trip fix, so we swapped the entire post base with a galvanized steel sleeve to prevent future rot.
Rail Repair
Heavy wooden farm gates on Sebastopol’s former orchard properties — the ones that pre-date modern automation — stress their rails differently than lightweight suburban gates. We repair split or sagging rails with structural welding, sistering steel angle to weakened joints, and replacing rotted tenons. Winter atmospheric-river rain events swell these panels, and we’ve learned to build seasonal adjustment into our rail repairs for properties on the fog belt’s western edge.
Custom Welding
Our mobile welding rig handles field repairs that would strand a less-equipped technician. We fabricate gate catch boxes, repair broken operator mounts, extend posts for automation retrofits, and build custom roller assemblies for gates that never had standard hardware. Sebastopol’s mix of Victorian-era wrought iron, mid-century ranch tube gates, and heavy agricultural swing gates demands welding fluency across materials and eras — 31 years of it.

Trusted Brands We Service in Sebastopol
We’re factory-familiar with your brand — not guessing from a manual. We carry parts and diagnose systems for LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That means when your LiftMaster LA500 or FAAC 415 hits a mechanical fault on a Sebastopol property, we’re not ordering parts for next week. We stock common failure items — control boards, gear kits, limit switches, hydraulic fluid — and we know the welding and structural fixes that get the mechanical side working again. For older openers on Sebastopol’s rural parcels, parts availability can make or break a repair; our inventory covers decades of production runs.
Common Gate Parts & Welding Problems We See in Sebastopol Homes
- Fog-rotted redwood post bases. Even redwood, Sebastopol’s historically dominant gate material, succumbs to ground-level moisture in the coastal fog belt. Post replacement with galvanized steel sleeves is often the only permanent fix.
- Premature hinge and latch corrosion. Ferrous hardware rusts in the marine layer within 2–3 seasons, causing binding, squealing, and eventual failure — a chronic issue nearly absent in drier Santa Rosa just five miles east.
- Seasonal gate binding after winter rains. Atmospheric-river events swell wooden panels in frames, a failure mode Sebastopol property owners recognize well and that requires either seasonal adjustment or custom welding to enlarge clearances.
- Failed automation on heavy farm gates. The rural agricultural parcels ringing Sebastopol — former orchard and pasture properties — carry decade-old heavy wooden swing gates or tubular farm gates that pre-date modern automation, a repair demographic nearly absent in suburban Rohnert Park or Windsor.

FAQs — Gate Parts & Welding in Sebastopol
The marine layer pushed through the Petaluma Gap keeps ground-level humidity chronically high here, far above drier inland Sonoma County. Even redwood, naturally resistant to decay, eventually succumbs when its base sits in persistently damp soil through hundreds of foggy mornings annually. We replace rotted bases with galvanized steel sleeves or pressure-treated posts set on gravel drainage — call (628) 261-6223 and we’ll assess whether your posts are salvageable or need full replacement.
Yes — sagging after atmospheric-river events is one of our most common Sebastopol calls. We typically diagnose whether the issue is post rot, hinge elongation, or rail joint failure, then weld structural reinforcements or replace the compromised component. Heavy wooden farm gates on rural parcels are our specialty, not an afterthought. Call (628) 261-6223 for a free estimate — we bring the welder to you.
We stock parts for multiple production generations of both brands, including discontinued control boards and gear kits that keep older systems running. For Sebastopol’s rural properties with decade-old openers, replacement isn’t always necessary — often a $180–$340 parts repair outlasts a cheap new unit. Call (628) 261-6223 with your model number; we’ll tell you if we’ve got it on the truck.
Probe the base with a screwdriver — if it sinks in easily or you see fungal growth, replacement is likely. If the post is solid but the hinge mount has torn away, custom welding a heavier backing plate usually suffices. Steven Lee assesses this on every Sebastopol estimate; call (628) 261-6223 and we’ll give you a straight answer, not a sales pitch.
Wooden panels swell from winter rain absorption, reducing clearances in frames and against latches — a seasonal failure mode Sebastopol’s fog belt exaggerates. We fix binding with seasonal adjustment, custom welding to enlarge clearances, or replacing swollen panels with moisture-stable materials. If your gate binds every January, it’s not “just winter” — it’s a design or maintenance issue we can resolve permanently. Call (628) 261-6223 before the next atmospheric river.
