AfterFast, Reliable Gate Repair Across Fairfax
Gate repair in Fairfax usually takes us half a day on site, and we answer the phone with a live person at (877) 610-2993 any hour of the day. If your gate sags, drags, or won’t open, the problem is almost always in the post, the hinge, or the operator, not the whole gate. We’ve worked on enough steep Fairfax driveways and fog-damp wooden gates to know what fails here and why, which means we show up with the right parts and the right welding gear the first time. Hal Gatewood put his name on this shop in 2001, and the shop is local to Marin County, not three states away.
Key takeaways:
- Live person answers 24/7 at (877) 610-2993, no voicemail queue.
- On-site welding means your gate stays in your driveway, not hauled off.
- 90-Day Done Right Promise in writing on every job.
- No trip charge inside Marin County, and $40 off any repair over $200.
Why Gatewood Fence & Gate Is Fairfax’s Preferred Gate Repair Company
Hal has been fixing gates since 2001, and around Fairfax that matters because the failures here aren’t generic. The bay laurel trees on nearly every residential lot shed acidic, tannin-rich leaves that pile up at gate post bases. That leachate blackens and degrades wood at ground level even when the gate looks structurally sound from above. We look for it on every wooden gate call because we see it on nearly every wooden gate call in Fairfax. Our Gate Repair crew knows to start at the post base before touching the hinges.
Fairfax homeowners tell us the same thing in reviews: a national outfit quoted one price over the phone and charged another at the door, or replaced a gate that could have been fixed. Hal’s answer to that is the 90-Day Done Right Promise, stamped in writing, not hidden in fine print. If it’s not done right, one call brings him back. No runaround, no re-dispatch. You can drive to the shop and look him in the eye.
Response time to Fairfax from our San Francisco Bay Area office is typically same day for repair calls, and we keep common parts for Linear, Ghost Controls, and DoorKing operators on the truck so a bad board or stripped gear doesn’t mean a two-week wait. Every technician is background-checked and uniformed, and the person who shows up is accountable to Hal by name, not to a call center.
Our Gate Repair Services in Fairfax
Hinge & Post Repair
A gate sags in the hinge post, not in the middle, and that’s where we start. In Fairfax, the hinge post is usually sitting in wet, tannin-rich bay laurel duff that’s been killing the wood below grade for years. We dig out the debris, assess how much sound wood is left, and either sister the post or set a new footing with slope-compensating brackets so the gate clears the uphill grade. Fix the panel without the post and you’ll fix it twice.
Electric Gate Repair
Electric gates in Fairfax spend their lives in a fog-and-canopy moisture cycle that most open-valley towns never see. That means control boards, photo eyes, and limit switches corrode faster than the manual says they should. We diagnose the operator, not just the symptom. If a LiftMaster or DoorKing board fails because moisture got into the housing, we’ll replace the board and seal the housing so it doesn’t happen again next winter.
Gate Realignment
Steep hillside driveways make swing gates bind on the grade during wet winters, and Fairfax has no shortage of steep driveways. When the soil shifts and the post leans half a degree, the latch won’t catch and the gate drags on the uphill side. We re-level the hinges, adjust the post alignment, and where the slope keeps winning, we’ll talk to you honestly about converting to a slide gate with a rack and pinion so you stop fighting the hill every spring.
Automatic Gate Repair
Automatic gate repair in Fairfax often comes down to one thing: the safety sensors and loop detectors are doing exactly what they were designed to do, which is stop the gate. Fog, wet leaves, and condensation on the photo eye lenses cause false triggers and intermittent failures that drive people crazy. We clean, realign, and test the entire safety circuit, including the loop detector at the driveway mouth, so the gate opens when your car pulls up and not whenever the fog rolls in. Show me the gate closing on its own and I’ll show you where it’s failing.
Lock Repair and Weld & Rust Repair
Fairfax’s nightly fog keeps gate hardware damp, and steel hinges and rack-and-pinion rails rust faster than they do in drier Marin towns. We weld on site, in your driveway, rather than hauling the gate off and leaving a gap in your fence line. If a lock is seized or the strike plate has shifted, we repair or replace it and then adjust the alignment so the lock actually engages without you having to shoulder the gate shut.

Trusted Brands We Service in Fairfax
We’re certified to service nine major gate brands, and around Fairfax we end up working on Linear, DoorKing, and Ghost Controls operators more than any others. That’s why we stock local parts for those brands and for LiftMaster and Mighty Mule as well, so a failed control board doesn’t mean we have to order from a warehouse and leave your gate stuck open. If your opener is older and parts are discontinued, Hal will tell you straight whether it’s worth repairing or time to replace, and he’ll never upsell you into a new operator just because it’s easier for him.
Common Gate Repair Problems We See in Fairfax Homes
- Tannin-rotted hinge posts below grade: Bay laurel leaves pile up at the post base, leach tannic acid into the wood, and blacken it at ground level. The gate looks fine from above, but the post is soft below the soil line, and the gate starts dragging on the uphill slope.
- Rust on hinges and rack-and-pinion rails: Fairfax’s valley traps coastal fog in the canopy most mornings and evenings, and that moisture never really dries out. Steel hardware that would last decades in Novato rusts through in Fairfax if it’s not galvanized or stainless.
- Swing gates binding on sloped driveways: Many Fairfax homes were carved into the hillside, and the driveway rises steeply from the road. During wet winters the soft, root-riddled soil shifts, the post leans a degree or two, and the gate catches on the grade. Realignment fixes it, but only if the post itself is still sound.
- Shared driveway complications: Fairfax has a lot of shared driveways and narrow rights of way where a swing gate won’t fit. We install and repair slide gates and keep vehicle and pedestrian access working during the job so neighbors aren’t locked out.

FAQs - Gate Repair in Fairfax
The bay laurel trees on nearly every Fairfax lot shed acidic, tannin-rich leaves that pile up at gate post bases and leach tannic acid into the wood below grade, blackening and degrading it even when the visible gate looks sound. Combined with the valley’s nightly fog that never really lets the wood dry out, the post rots from the bottom up. That’s the dominant failure mode we see on wooden gates here, and the fix is a new post footing with proper drainage and clearance from the soil line. Call (877) 610-2993 for an assessment.
Usually yes. The drag is almost always caused by the hinge post leaning or sinking as the hillside soil shifts in the wet season, not by the gate panel itself. We re-level the hinges, adjust the post, and install slope-compensating brackets if the grade demands it. If the post is too far gone, we replace the post, not the gate. Call (877) 610-2993 and we’ll take a look.
Photo eye sensors can false-trigger or fail intermittently when condensation and fog film the lenses, which happens regularly in Fairfax’s valley. Loop detectors in the driveway are generally more reliable in fog, and we often recommend both: photo eyes for entrapment protection and a loop detector to open the gate when a vehicle pulls up. We test the whole safety circuit so the gate opens when it should and stops when it should.
Keep the area around the post base clear of leaf litter, especially against the wood, and make sure soil and mulch aren’t piled above the original grade line. We can also wrap the below-grade section of a new post in the proper barrier and set it with gravel drainage so water moves away instead of sitting against the grain. The tannins in bay laurel leaves are persistent, so clearance and drainage matter more than any sealant.
Yes, but it has to be set up with the right safety loops and access controls so both houses can enter and exit without conflict. Fairfax has a lot of shared driveways and narrow rights of way, and the operator, loop placement, and swing or slide direction all have to respect the shared use. We’ll measure the driveway, check the grade, and quote the whole system, including the power run and safety edges, before any work begins. Call (877) 610-2993 for a free measure and written price.
On Scenic Road, We Rebuilt What the Wet Duff Destroyed
On Scenic Road in Fairfax, we rebuilt a Craftsman-era wooden swing gate whose hinge post had rotted at the base from decades of wet bay laurel duff. We set a new post footing with slope-compensating brackets, installed a LiftMaster gate operator with a loop detector for vehicle exit, and re-hung the gate with sag correction so it clears the steep uphill driveway while pedestrians keep using the side path. The gate stayed in the driveway the whole time, and the homeowners watched every step. That’s how we work in Fairfax: on site, with your gate, until it’s done right.
