AfterFast, Reliable Gate Parts & Welding Across Sunnyvale
Gate parts and welding in Sunnyvale means fixing what’s already there when it’s worth saving, and replacing it when the math says otherwise. Hal Gatewood has been doing exactly that since 2001, and most of what we see in Sunnyvale is older iron and wood gates that were added to ranch homes 25 to 40 years ago, now failing at the hinge posts, rails, and weld joints all at once. If your gate is sagging, dragging, or no longer closing square, call (877) 610-2993 and we’ll send someone who can weld on site in your driveway, not haul your gate to a shop across the county.
Why Gatewood Fence & Gate Is Sunnyvale’s Preferred Gate Parts & Welding Company
We earn Sunnyvale’s trust one repair at a time. Homeowners in 94086 and 94087 call us because we still believe a broken hinge doesn’t mean a whole new gate. That repair-first habit comes from Hal’s shop, where the name on the door is the guy who shows up. We stock common gate parts for our Gate Parts & Welding work, so we’re not waiting a week on a hinge or roller when your gate is off its track. Calls are answered by a live person around the clock, not a voicemail. The person on the phone usually knows whether a snapped weld or a worn hinge is causing the sag before we even see it.
Response time to Sunnyvale is a phone call away, not a three-day window. We keep crews moving through the South Bay, and because we carry parts and welding gear in the truck, most gate repairs in Sunnyvale are finished in one visit. Every job gets the 90-Day Done Right Promise in writing. If it’s not right, one call brings Hal back. No runaround, no fine print. That promise matters to homeowners in Sunnyvale who’ve been burned by national outfits that quote one price on the phone and a higher one at the door.
Our Gate Parts & Welding Services in Sunnyvale
We handle the full range of gate parts and welding work for Sunnyvale homes and businesses, and we do it with a welding torch and parts bin in the truck. Here’s what that means for the four services Sunnyvale calls about most.
Hinge Replacement
Hinges on older Sunnyvale gates do more work than they should because the gate was probably hung heavier than the original design allowed. In the 1980s and 1990s, a lot of 94086 and 94087 ranch houses got decorative iron and wood driveway gates as security upgrades, often bolted to existing fence posts that weren’t built for that load. We replace the hinge, sure, but we also check that the post can still hold it. A hinge swapped onto a failing post is a hinge you’ll pay for twice.
Post Replacement
This is the $400 to $900 question in Sunnyvale: fix the post or replace the whole gate? A gate sags in the post, not in the middle, and that’s where we start. Wood posts in older Sunnyvale yards rot at the base after wet winters, and steel posts in 94089 near the baylands rust through where salt air sits against the concrete. We cut out the old post, set a new one in concrete, and weld the hinge plates square. Gate straight, closes true, done.
Rail Repair
Rails are the horizontal frame members that carry the pickets or the wood planks. When wood gates swell during Sunnyvale’s wet winters and shrink through dry summers, the planks pull against the rail bolts and the rails crack or twist. We weld new steel rails in place or sister in new wood, depending on what the gate is made of. If the rail joints were welded badly the first time, we grind the old weld back and do it so the corners don’t reopen.
Custom Welding
Some gates can’t be bought off a shelf, and Sunnyvale has plenty of them. We weld custom frames, repair broken scrollwork on older wrought iron gates, and fabricate mounts for operators and safety hardware that weren’t there when the gate was hung. When a 1990s commercial slide gate in 94089 needs a new rack welded to the frame, we do it in place and free the rollers while we’re there. When a residential gate in 94087 needs a hinge relocated because the post shifted over 30 years, that’s custom work too. We build it, weld it, and stand behind it with the 90-Day Done Right Promise.

Trusted Brands We Service in Sunnyvale
We service what Sunnyvale already has, not just what’s easy. That includes FAAC slide operators still working through corporate campus gates near Moffett Field, Linear swing operators on older patio and driveway gates in 94086, and a fair number of BFT and Viking units on HOA community entry gates. We stock common replacement parts for these brands and can order the oddball parts quickly. For Sunnyvale customers, that means we don’t spend a week waiting for a control board while your gate sits open.
Common Gate Parts & Welding Problems We See in Sunnyvale Homes
- Sagging 1980s-90s retrofit gates in 94086 and 94087. These gates were often hung on fence posts that were never meant to hold a 200-pound gate. Hinge posts lean, the gate sags at the latch side, and the fix starts with the post, not the hinge.
- Salt-air seizure on commercial slide gates in 94089. The baylands air pushes moisture and salt into chain drives, rack teeth, and roller bearings. A slide gate that worked fine in June may barely move by January. We clean, replace, and re-lubricate the running gear and weld what the salt ate through.
- Wooden plank swelling and pulling away from hinges. Sunnyvale’s wet winters make wood gates soak up water, expand, and twist against the hinge plates. By summer the gate sags to one side and won’t latch. We replace the planks, re-secure the hinge plates with heavier screws, and seal the top edges so it doesn’t repeat next year.
- Pre-UL 325 gates with no entrapment protection. A lot of automated gates in Sunnyvale were installed before modern safety photocells and reverse-edge requirements became standard. We retrofit safety edges and photocells onto existing operators, often without replacing the operator itself.
Pricing for Gate Parts & Welding in Sunnyvale, CA
Gate parts and welding in Sunnyvale are priced by the job, and you’ll hear the number before we do any work. A sagging gate hinge replacement on a residential gate in 94086 typically runs $150 to $350, depending on the hinge and how far the post has moved. Post replacement runs $400 to $900, which includes cutting the old post, setting a new one in concrete, and re-hanging the gate square. Custom welding for cracked rails, broken scrollwork, or operator mounts runs $85 to $150 per hour plus materials, and rail repair is $150 to $450 for most residential gates. Commercial gear in 94089 runs higher because the hardware is bigger and the safety system checks take longer. Here’s what moves the price in Sunnyvale: how much salt damage we’re repairing, how heavy the gate is, and whether the operator needs new safety edges or photocells at the same time. Every job gets a quote in writing before we touch a tool, and we offer a free second opinion on any written estimate you’ve already gotten. There’s no trip charge inside the county, and we take $40 off any repair over $200.

FAQs - Gate Parts & Welding in Sunnyvale
Salt-laden marine air off the bay attacks iron and steel much faster than what homeowners in inland Sunnyvale zip codes ever deal with. Hinges that would last 20 years in 94087 can seize or rust through in 10 to 15 years up near the baylands. The fix is replacing the hinge with a marine-grade or sealed-bearing unit and treating the surrounding frame for rust before re-welding. If your gate is within a mile of the bay, call (877) 610-2993 and we’ll inspect the hinge posts and running gear together.
Welding can repair the gate frame, but the sag almost always starts in the hinge post, not the gate itself. If the post is still solid and plumb, we can weld reinforcement plates, re-hang the gate, and stop the sag. If the post has rotted at the base or cracked at the hinge plate, welding around it wastes your money, and a new post is the correct fix. We’ll show you which one you have before any work starts, and you’ll know the price first.
Yes, in most cases we can add safety photocells and a reverse-edge sensor to an existing operator, as long as the control board has the input terminals for them. Many FAAC, Linear, and BFT operators from the 1990s and 2000s can accept these additions. We’ll wire them in, test the reversal function, and leave the gate compliant with current UL 325 entrapment protection standards without making you buy a new operator.
In-ground vehicle loop detectors near Moffett Field fail frequently because bayland moisture seeps into the saw-cut groove in the asphalt, corrodes the wire, and shorts the loop circuit. The gate then won’t open from the vehicle side, or it opens and re-closes on the same car. We locate the break, replace the loop wire, reseal the groove, and retune the detector to the gate’s control board on the same call.
We replace the hinge when the frame is still sound, which is the case for most older wrought iron gates in 94086 and 94087. Wrought iron is tough, and it’s usually the hinge pins, hinge plates, or post attachments that fail first. We weld new hinge plates to the frame when needed, replace the pins, and re-hang. If the frame itself has cracked through at the weld joints, we’ll repair those joints too. You’ll see the gate before we weld anything.
