AfterFast, Reliable Gate Parts & Welding Across Corte Madera
Gate parts and welding in Corte Madera come down to one thing most national companies won’t tell you: the salt air here eats hardware faster than almost anywhere else in Marin. A hinge that would last fifteen years in Fairfax can seize solid in five on a bay-flat street near the Corte Madera Marsh. Hal Gatewood has been cutting out corroded posts, welding new footings, and rebuilding gate frames since 2001, and we stock the hinges, rollers, and enclosure hardware that actually survive this climate. If your gate is sagging, grinding, or rusting through, call (877) 610-2993 and a live person answers, day or night.
Why Gatewood Fence & Gate Is Corte Madera’s Preferred Gate Parts & Welding Company
We’re not a franchise and we don’t route calls through a queue somewhere in another state. Hal Gatewood’s name is on the shop, the address is published, and the person who answers the phone at 2 a.m. is the same person who’ll show up at your driveway. Corte Madera homeowners call us because we fix what’s actually broken instead of quoting a full replacement the moment we see rust. The Gate Parts & Welding team welds on site, in your driveway, so your gate never leaves your property. That means less downtime, no haul-away fees, and a repair you can watch happen.
We’ve repaired Viking swing gates on hillside lots near Ring Mountain, rebuilt slide gates in the 94925 flats, and rehung driveway gates across 94976 where the marine layer never really burns off. Bay-flat Corte Madera properties have a failure pattern we know cold: seized hinge posts, pitted steel frames, and water-wicked control boards. When we quote a job, we write the price down before any work starts. You’ll know the number before we strike an arc. And every job carries our 90-Day Done Right Promise in writing. If it’s not done right, we make it right. No fine print, no runaround.
Our Gate Parts & Welding Services in Corte Madera
We carry and install the parts that actually hold up in Corte Madera’s marine air, and we weld what can be saved rather than sending you a bill for a new gate. Here’s where we do the most work in town.
Hinge Replacement
Salt-laden fog off San Francisco Bay attacks gate hinges year-round here, and on low-lying streets near the marsh the moisture never fully dries. We cut out seized or pitted hinges and weld in new ones rated for marine exposure, then set the gate so it swings cleanly without dragging. A hinge replacement in Corte Madera typically runs $280-$520 per hinge depending on gate weight and access.
Post Replacement
A gate sags in the hinge post, not in the middle, and Corte Madera’s saturated bay-flat soil rots post footings faster than inland Marin. We dig out the old post, weld a new footing and post in place, and reset the gate to its proper arc. Typical post replacement in Corte Madera runs $900-$2,400 depending on post size, concrete depth, and whether the gate is automated. We don’t quote that range and then charge the top end; the written quote is the number you pay.
Rail Repair
Long driveway gates on wide Corte Madera lots put enormous stress on the rail, especially slide gates with rack and pinion drives. We straighten bent rails, weld cracks and fatigue points, and re-align the track so the gate stops jerking and grinding. Rail repair here usually runs $350-$900. If we can weld it solid, we won’t sell you a new rail.
Custom Welding
Sometimes the part that failed doesn’t exist anymore. Corte Madera has plenty of 1990s and 2000s automated gates built around Viking and DoorKing hardware that’s now discontinued. Hal fabricates replacement brackets, hinge plates, receiver mounts, and frame sections on site from steel stock, matched to the existing gate and finished to resist the salt air. Custom welding jobs in Corte Madera run $180-$650 for most bracket and plate work, more for full frame sections.

Trusted Brands We Service in Corte Madera
We service the operators Corte Madera actually has on its driveways: Viking, DoorKing, Elite, and more. Many were premium installs in the 1990s and 2000s and are now aging out of parts availability. We stock common hinge pins, rollers, brackets, and enclosure hardware for Corte Madera jobs, and what we don’t have on the truck we can usually source within a day or two. That keeps your gate working while the part is on its way. If you have a Mighty Mule or Ghost Controls opener that’s still in service, we work on those too.
Common Gate Parts & Welding Problems We See in Corte Madera Homes
- Seized hinge posts on bay-flat streets. The marine layer rolls in off the bay almost nightly, and properties near the Corte Madera Marsh rarely dry out completely. That constant salt moisture wicks into hinge posts and freezes them solid within a few years. We cut them out and weld in replacements with marine-grade coatings.
- Water-wicked control boards in buried conduit. Low-lying lots with poor drainage allow salt moisture to travel through conduit into operator enclosures. We routinely find shorted loop detectors and corroded logic boards, and we recommend sealed NEMA-rated enclosures as a baseline here, not an upsell.
- Pitted steel frames on gate panels. Salt air doesn’t just attack hinges. The gate frame itself loses steel to oxidation, especially along the bottom rail where moisture pools. We weld in new steel and reinforce before the frame fails and drops the gate.
- Fatigued rack and pinion drives on wide slide gates. Corte Madera’s wider driveway openings put slide gates through longer travel cycles, and years of salt exposure plus lack of under-gate clearance wear the rack teeth down. We replace rack sections and re-align the drive so the gate moves without jumping or grinding.

FAQs - Gate Parts & Welding in Corte Madera
Because Corte Madera sits hard against San Francisco Bay and the Corte Madera Marsh, and the marine layer that rolls in almost nightly never fully dries out on the flats the way it does a few miles inland. Salt-laden moisture stays trapped around hinge posts and gate hardware, so oxidation progresses year-round instead of seasonally. Fairfax and San Anselmo get fog too, but their air is drier between events, so the corrosion cycle pauses. On Corte Madera bay-flat streets it never really stops. We replace hinges here with marine-rated hardware and welded posts that slow the process significantly. Call (877) 610-2993 and we’ll tell you if your hinges are salvageable or need to be cut out.
Yes, in most cases. We support the gate in place with stands and bracing, cut out the failed post, weld in a new footing and post, and re-hang the gate on the new hardware. Your gate stays in your driveway the whole time, which matters because removing an automated gate means disconnecting the operator, safety edges, and loop detectors before any metal work starts. Hal and his crew handle that carefully. Give us a call at (877) 610-2993 and we’ll give you a straight answer on whether your post can be replaced in place, usually without hauling anything off site.
Yes, it will, faster than you’d think on the Corte Madera flats. Standard plastic enclosures aren’t sealed against the fine salt moisture that travels through buried conduit and condenses inside the box. We regularly pull corroded LiftMaster and Viking logic boards out of enclosures that look fine from the outside. The fix is a sealed NEMA-rated enclosure, which we recommend as a baseline for bay-flat Corte Madera homes, not as an upsell. It costs more up front than a plastic box, but it’s a lot cheaper than replacing a control board every three years. Call (877) 610-2993 and we’ll assess what you’ve got.
No, it is not normal. Jerking and grinding on a slide gate usually means the rack and pinion drive is misaligned, the rack teeth are worn, or the gate rollers are seizing from salt corrosion, all of which we see regularly on wider Corte Madera driveway openings. The longer the gate, the more leverage any single bad roller or worn rack section has, and the grinding gets worse fast. We re-align the drive, replace worn rack sections, and service or swap the rollers so the gate moves smoothly along its full travel. Call (877) 610-2993 and we’ll come look at it.
If the post is solid and the gate frame itself has sagged or cracked, welding the panel can fix it. But on Corte Madera bay-flat properties, a sagging gate is usually the hinge post failing, not the panel. Welding the panel without addressing a rotted or loose post means you’ll be calling us again in a year or two. We always check the post first, because that’s where the problem starts. If the post is sound and the frame is the issue, we weld it on site and reinforce the joints. The written quote will tell you exactly what we found and what needs fixing.
