AfterFast, Reliable Gate Parts & Welding Across Sausalito
Worn hinge posts, cracked weld seams, and obsolete operator boards are the reality of gate ownership in Sausalito, where salt fog off the Golden Gate eats unprotected steel faster than almost anywhere else in Marin. Replacing hinges, posts, rails, or doing on-site custom welding is work we handle every day. A typical hinge replacement in Sausalito runs $180-$420, post replacement $650-$1,800 depending on footing depth and hillside access, and custom welding $150-$400 per hour. If you need someone who understands what bay spray does to gate hardware, call Hal at (877) 610-2993.
We’re Gate Parts & Welding specialists, and we’ve been welding gates in driveways from Hurricane Gulch to the Richardson Bay waterfront since the shop opened. Sausalito gates fail differently than gates ten miles inland. That’s not marketing. It’s chemistry, geography, and a lot of rust we’ve cut out of posts over the years.
Why Gatewood Fence & Gate Is Sausalito’s Preferred Gate Parts & Welding Company
Hal Gatewood started this shop in 2001 and his name is on every invoice. When you call about a sagging gate or a hinge that finally gave way on your Sausalito hillside, you’re talking to someone who will show up, look at the post with his own eyes, and tell you whether it needs welding or replacing. If it’s a closer call, he’ll tell you that too. The published address and license number are there for anyone who wants to check before we set foot on the property.
Our Sausalito customers call us because we answer the phone with a live person around the clock. Not a voicemail tree. Not a call center three states away. When a gate motor dies at 9 p.m. and the driveway is open to Bridgeway traffic, you want to hear a human voice on the other end. That’s what you get.
Every job gets our 90-Day Done Right Promise in writing. If something isn’t right, one call brings Hal back. No runaround. No “that’s normal wear.” The guarantee is stamped on the paperwork, not buried in fine print. We also offer $40 off any repair over $200, a free second opinion on any written estimate, no trip charge inside Marin County, and a permanent 10% discount for seniors and veterans.
Our Gate Parts & Welding Services in Sausalito
We fix gates in the driveway, not by hauling them to some shop and swapping parts you didn’t need. Here’s what that looks like in Sausalito.
Hinge Replacement
Sausalito’s salt fog is brutal on hinges, especially where powder coating has been scraped off by the gate swinging thousands of times. A seized or cracked hinge on a steel gate off Alexander Avenue or near Hurricane Gulch is usually a weld job, not a full gate replacement. We cut out the old barrel, weld in the new hinge, and align the leaf so the gate hangs true. Most hinge replacements run $180-$420 and take one visit.
Post Replacement
On hillside lots in Sausalito, the hinge post takes the entire load of the gate, plus whatever the clay-heavy cut-and-fill soil decides to do after a wet winter. We remove the rotted or leaning post, pour a new concrete footing keyed into the slope, and in marquee cases, weld a galvanized sleeve around the replacement post to buy decades against bay-driven salt spray. Two seasons from now, that post won’t be the reason your gate sags again.
Rail Repair
Bottom rails on Sausalito gates rot from the inside out when salt fog condenses on untreated steel. We cut out the compromised section and weld in a spliced replacement, or replace the full rail if the rot has run too far. If the gate is on a steep grade, we’ll also check the bottom roller and track alignment while we’re in there. A loose roller on a graded driveway wears rails twice as fast.
Custom Welding
Sometimes the part doesn’t exist because the gate was custom-built in 1962. We weld brackets, mounting tabs, vertical pickets, and frame gussets on site. Aluminum gate frames on floating-home docks in the Richardson Bay community are a specialty. Aluminum requires a different weld process and filler metal than steel, and we come set up for it. Custom welding on a Sausalito gate typically runs $150-$400 per hour, depending on the metal and the position.

Trusted Brands We Service in Sausalito
We’re certified to service nine major gate brands, and we keep common parts on the truck for Viking, DoorKing, and Elite operators. For older units still running around Sausalito, that’s a big deal. A DoorKing control board from the 1990s fails, and you don’t want to wait two weeks on a part while your driveway sits open. We carry or can source the parts quickly, and if we can’t, we’ll tell you honestly whether retrofitting or replacing the operator is the smarter money.
Common Gate Parts & Welding Problems We See in Sausalito Homes
- Weld seams cracking at the hinge plate. Salt fog off the Golden Gate gets behind the powder coating wherever the gate scrapes hardware. Weld joints on mild steel crack and flake within two or three seasons, and the gate starts to lean. We weld new plates and re-coat the seam so moisture has nothing to grab.
- Post-lean after wet winters. Sausalito’s hillside lots are built on clay-heavy fill that saturates in winter rain and shifts. Every spring, we respond to gates that have gone stiff or misaligned because the post moved. Welding alone doesn’t fix a post lean; the post gets reset and re-footed, then the hinges are re-welded to the corrected position.
- Obsolete operator boards with no manual release. Pre-UL 325 operators don’t have the entrapment protection or quick release modern systems do. They fail without warning, sometimes leaving the gate stuck half-open. We retrofit safety photocells and keypads onto older operators that still have life, rather than telling you to rip out everything.
- Dock gate hardware flexing with the tide. On floating homes in Richardson Bay, gate mounts have to move with the dock. Rigid steel frames bolted straight down crack at the welds when the platform shifts. We weld flex-tolerant hardware and use aluminum or stainless where salt spray is constant.
Pricing for Gate Parts & Welding in Sausalito, CA
We price every job upfront, in writing, before work starts. You know the number before we cut the first weld. That’s not a courtesy; it’s the only way Hal runs this shop.
- Hinge replacement: $180-$420 per hinge, depending on gate weight and access
- Post replacement (steel, hillside footing): $650-$1,800, including excavation, concrete, and re-hanging
- Rail repair (sectional splice or full rail): $220-$700
- Custom welding (steel or aluminum, on site): $150-$400 per hour, quoted per job
- Obsolete operator retrofit with safety photocells: $350-$850 parts and labor
What moves the number: hillside access, soil condition at the post, and whether the gate is steel or aluminum. A flat driveway in the flats from the 1940s will run closer to the bottom of the range. A steep cut lot off Prospect Avenue with a 16-foot wrought iron gate might run higher. Call (877) 610-2993 for a free estimate. We’ll give you a written number and stick to it.

FAQs - Gate Parts & Welding in Sausalito
Sausalito sits at the mouth of the Golden Gate strait. Near-daily salt fog and wind-driven bay spray creates a corrosion microclimate that Mill Valley’s tree-covered hillsides never see. Unprotected mild-steel weld joints on swing gate hinges and posts can fail in under five years here, while the same hardware ten miles inland in San Rafael might last triple that. The difference is airborne salt, and it’s relentless. If your gate is steel and showing rust at the welds, call (877) 610-2993 sooner rather than later.
In most cases, yes. We cut out the rotted post at the base, excavate the old footing, pour a new footing, and set the replacement post. The gate is temporarily supported while the work is done, so we rarely need to remove the whole gate or tear up surrounding driveway. Steep Sausalito hillsides sometimes limit access, but that’s exactly why we bring welding gear and materials for on-site work.
No, not in good conscience. UL 325 entrapment protection has been the standard for decades now, and a 1970s operator without photo-eyes or edge sensors is a safety risk to anyone walking a dog or a grandchild through that gate. If the operator is running, we can often retrofit safety photocells and a keypad without replacing the whole unit. It costs less than a new motor and keeps the gate safe. Call and we’ll assess it.
Because Sausalito’s hillside lots sit on clay-heavy cut-and-fill that saturates with winter rain and shifts. The post moves, the alignment throws off, and the gate sags. Welding the hinge back on without addressing the post will last one season. The post gets reset and re-footed, then the hinges are re-welded to the corrected position. That’s the only repair that holds.
Yes. Aluminum welding on floating docks is a specific skill. The frame has to tolerate tidal rise-and-fall and constant salt spray. We use aluminum-specific welding, stainless hardware, and flex-tolerant mounting. We’ve done dock gate work in the Richardson Bay houseboat community and we know what warps, what cracks, and what holds. Call (877) 610-2993 if your dock gate is misaligned or cracking at the welds.
