AfterFast, Reliable Gate Parts & Welding Across Sylmar
If your gate hinge tore loose or a post is leaning after the last Santa Ana blow, we can usually be at your Sylmar property the same day. Hal Gatewood has been welding and repairing gates since 2001, and our Gate Parts & Welding crew knows exactly what the Newhall Pass winds do to steel and aluminum. Call (760) 361-6706 and a live person answers, 24/7. You won’t get a voicemail, and you won’t get a call center in another state. You’ll get someone who knows Sylmar and can tell you honestly whether that hinge can be welded back or whether the post underneath it is the real problem.
We serve all of Sylmar, from the ranch properties along Foothill Boulevard to the hillside streets above Hubbard and the older tracts below the pass. Every estimate is free, the price is quoted and agreed before any work starts, and every job carries our 90-Day Done Right Promise in writing.
Why Gatewood Fence & Gate Is Sylmar’s Preferred Gate Parts & Welding Company
Hal Gatewood’s name is on the shop, his address is published, and his license number is there for anyone to look up. That matters in Sylmar, where a lot of homeowners have already been burned by a national outfit that quoted one number on the phone and charged another at the door. You can drive to the shop and look Hal in the eye. That’s the oldest accountability there is.
Sylmar homeowners keep our number because when they call at 9 p.m. on a Sunday with a gate that won’t close and a horse that could walk out onto Foothill, a live person picks up. Not a bot. Not a “your call is important to us” recording. Hal or one of his crew answers and figures out what’s actually going on.
We’ve pulled into driveways off Glenoaks, up along Sayre, and out on the equestrian lots near Little Tujunga where the gate is the only thing between a 1,500-pound animal and a busy road. The work we do there gets inspected by people who know what a good weld looks like, and it holds up. We stand behind it with a written 90-Day Done Right Promise. If it’s not done right, one call brings us back, no runaround.
You won’t get a “replacement specialist” who shows up with a catalog and tries to sell you a whole new gate when the real problem is one cracked hinge bracket. You get a welder with a machine on the truck who fixes the gate in your driveway. That’s the difference, and it’s why Sylmar keeps calling.
Our Gate Parts & Welding Services in Sylmar
Hinge Replacement
On Sylmar’s older gates, the hinge is almost never the whole story. We cut out the twisted mount, weld in a reinforced plate, and hang the gate on heavy-duty ball-bearing hinges sized for wind load, not just weight. If you’ve replaced hinges on the same gate twice, the problem is probably the post behind them. Fix the panel without the post and you’ll fix it twice.
Post Replacement
Here’s what makes Sylmar different from every other Valley community: a lot of gate posts on pre-1975 equestrian and ranch properties were set in shallow footings that the 1971 San Fernando earthquake cracked and shifted, and nobody ever replaced them. So a leaning post here is usually a footing problem, not a hinge problem. We probe and excavate the base before we assume a post can just be re-plumbed. If the footing is shot, we set a new post deeper, re-weld the hinge mounts, and bury the evidence so the gate swings true through the next wind event.
Rail Repair
Santa Ana gusts funneling through the Newhall Pass bow aluminum gate frames and shear lower rail welds at a rate you don’t see down in Panorama City or Sun Valley. A bent bottom rail makes the gate rack against the ground, which stresses the hinges, which strains the operator motor. We straighten or splice the rail, re-weld the joints, and check the gate’s travel so it isn’t working against itself.
Custom Welding
Sometimes the gate is fine and the geometry isn’t. We’ve cut and re-welded hinge mounts on 14-foot tubular steel swing gates on large-lot equestrian properties off Foothill Boulevard, fabricated latch striker plates for gates that never lined up right from the day they were installed, and rebuilt slide-gate carriages that had worn through their bearings. If it’s steel or aluminum and it’s part of your gate, we can usually weld it on the spot.

Trusted Brands We Service in Sylmar
We stock parts and weld-mount hardware for the operators Sylmar actually has on the ground: LiftMaster, DoorKing, Mighty Mule, and Elite, among others. That includes legacy Viking operators from the 1990s that national companies won’t touch because the parts aren’t in their system. We can source them. If you’ve got an old DoorKing slide-gate board that’s fried and a gate stuck halfway open, call us before you let anyone sell you a whole new operator. We’ll tell you straight whether the board can be matched, retrofitted, or whether it’s finally time to retire it.
Common Gate Parts & Welding Problems We See in Sylmar Homes
- Wind-sheared hinge welds on aluminum swing gates. The Newhall Pass funnels Santa Ana gusts straight into Sylmar, and an aluminum gate that’s been flexing for ten years finally lets go at the top hinge. We re-weld the mount and often add a reinforcement plate so the repair outlasts the original.
- Leaning hinge posts from 1971 quake-shifted footings. On older equestrian and ranch properties, shallow footings cracked in the San Fernando earthquake and settled over decades. The gate binds at the latch side, and the operator motor strains every cycle. We excavate, set a new post deeper, and re-hang the gate.
- Slide gates jumping the track during wind events. Worn rollers plus direct crosswind from the pass equals a gate that derails itself. We replace rollers, adjust the track, and check the guide posts. A gate that jumps its track is dangerous, especially with kids or horses around.
- Obsolete control boards on pre-UL 325 operators. A lot of legacy operators around Sylmar have no safety photocells and no entrapment protection. When the board fails, we can sometimes retrofit safety edges and photocells onto an otherwise solid mechanical unit. When we can’t, we tell you honestly and quote you a replacement that meets current safety standards.

FAQs - Gate Parts & Welding in Sylmar
Because the problem is almost never the post itself on Sylmar properties built before 1975. The 1971 San Fernando earthquake cracked shallow footings and shifted them laterally, so the whole footing settles and lets the post lean. Re-plumbing a post on a bad footing is a temporary fix. We excavate the base, inspect the footing, and when it’s cracked or undersized, we set the post in a deeper, properly reinforced footing. That’s the only repair that lasts. Call (760) 361-6706 and we’ll come look at the base before we touch the post.
It depends on the board, but we can often retrofit safety photocells and safety edges onto older LiftMaster operators that still have solid motors and gear trains. Pre-UL 325 operators are the ones we look at hardest, because if the board can’t support entrapment protection, it’s a safety liability, not just an inconvenience. We’ll tell you plainly whether retrofitting is worth it or whether a new operator is the cheaper answer over five years. Estimates are free.
Usually both. The winds that funnel through the Newhall Pass hit a slide gate broadside, and worn rollers don’t hold the gate stable under that load. We check roller wear first, then the track alignment, then the guide posts. On Sylmar slide gates, we usually replace the rollers and reset the track in one visit. Call (760) 361-6706 and we’ll get it holding true before the next wind event.
If the panel itself is sound and only the hinge mounts are failing, weld repair is the right call and it’s cheaper than new hinges and a lot cheaper than a new gate. But if the post behind the hinge is moving or the frame rail is cracked at the weld point, you’ll chase the problem forever by just swapping hinges. We’ll show you exactly what’s failing before we quote anything. A free second opinion on any written estimate is part of how we work.
Yes. We still source Viking parts for legacy operators, and we carry new stock for Mighty Mule, DoorKing, LiftMaster, and Elite. Old doesn’t automatically mean junk. If the motor’s healthy and the board can support safety retrofits, keeping a 90s Viking running is often cheaper than a full replacement. If it can’t, we’ll tell you that too. Call us at (760) 361-6706 and we’ll figure out which path costs less over time.
