If your FAAC gate is sagging, grinding, or refusing to close all the way, the hinges or rollers are the usual suspects. We stock FAAC-compatible hinge and roller replacements for most residential swing and slide gate models, and a typical hinge and roller replacement in San Francisco runs between $350 and $850 installed, depending on the gate’s size and how many points need attention. Most jobs are completed the same day we arrive.

Here’s how most people find us: the gate worked fine for years, then one morning it starts catching on the latch side, or the wheel leaves a groove in the driveway that wasn’t there before. Hinges and rollers don’t usually fail all at once. They wear down gradually, and by the time the gate starts acting up, the part has been quietly losing tolerance for months. In San Francisco, where the fog keeps things damp and many homes sit on sloped lots that add lateral pressure to gate hardware, that wear tends to show up a little sooner than it does inland.
Which FAAC Models This Applies To
Most of the FAAC hinge and roller replacements we handle are on the S418, S450H, and 390-series swing gates, plus the 740 and 844 sliding gate lines. FAAC uses a few different hinge pin diameters and roller wheel profiles across these series, so matching the part to the exact model matters. The simplest way to identify what you have is to check the silver data plate on the operator or the inside edge of the gate frame. If that plate is gone (it happens), we measure the hinge pin diameter and the roller wheel width on site before we quote anything.
One thing worth knowing: FAAC’s OEM rollers are well made but priced at a premium, and aftermarket equivalents hold up just as well for most residential gates in San Francisco’s climate. We carry both. If the gate is under a motor warranty, we’ll recommend OEM parts to keep that warranty intact. If it’s out of warranty, we’ll show you the OEM price and the aftermarket equivalent side by side, so the choice is yours before any work begins. Latch and Post Gate Repair San Francisco is an independent service provider, not affiliated with FAAC, but we’ve been installing their equipment for long enough to know which corners you shouldn’t cut.

Signs Your FAAC Hinge & Roller Replacement Is Failing
- The gate sags on the latch side. When the hinge pins wear down, the gate frame tilts by a few degrees and the latch no longer lines up with the strike plate cleanly. You might have to lift the gate slightly to get it to lock.
- You hear a metal-on-metal scrape when the gate moves. That’s usually the roller wheel bearing chattering or the hinge pin grinding inside a dry bushing. It gets louder in San Francisco’s damp months, when oxidation roughens the contact surfaces.
- The gate leaves a new arc-shaped groove in your driveway or walkway. A worn roller wheel flattens on one side and stops rolling, so it drags instead. Concrete work is a lot more expensive than a roller replacement.
- The gate shudders or wavers mid-swing. When hinge bushings develop slop, the gate’s momentum shifts the frame slightly off its axis. It looks like the motor is struggling, but the motor is usually fine.
- Opening or closing takes visibly longer than it used to. Friction from dragging hardware adds load to the FAAC operator, which slows down the movement and shortens the motor’s life. Replacing the hinge or roller early protects the more expensive component.
Replacement Cost & What’s Included
A hinge-only replacement on a single FAAC swing gate in San Francisco typically lands between $350 and $550 installed. Roller replacements run $250 to $450 per wheel, depending on whether we’re swapping just the wheel or the entire bearing assembly and track bracket. If both hinges and rollers need work on a larger gate, the total usually falls in the $600 to $850 range. Heavier gates (solid steel or thick wrought iron) sit at the higher end because the hardware is larger and the labor takes longer.
Every quote includes the parts, the labor, the adjustment to get the gate closing square and true again, and a written price before we start. We don’t surprise you with a bigger number at the end. The work is covered by our 365-Day Done Right Promise: if the hinge or roller isn’t right within a year, we make it right, no argument and no fine print. You’ll also get the Cedarwell Care routine on every visit: drop cloths down if we step inside to reach the control panel, shoe covers on, and a photo of the cleanup before we leave.

Here’s an honest split. You can absolutely check the hinge pins for visible wear: with the gate in the closed position, lift up on the latch-end corner and watch for movement at the hinge. If the gate shifts more than a quarter inch, the hinges are worn. You can also check the roller wheels for flat spots and spin them by hand to see if they turn freely. Those checks are safe and take about five minutes.
What you shouldn’t do is attempt to unbolt a loaded gate hinge or remove a roller cart from a gate that weighs several hundred pounds. Swing gates carry their full weight through the hinge pins, and once you loosen one pin, that weight has to go somewhere. Without the right blocking and a second set of hands, the gate can drop suddenly. The same goes for slide gate rollers: the gate’s center of gravity shifts the moment a wheel comes out. If you’ve done the visual check and something looks off, call us at (628) 227-2771. We’ll bring the parts, the blocking, and the years of practice.
FAQs
In San Francisco’s coastal air, which stays humid year-round, FAAC hinges and rollers typically last 8 to 12 years on a well-used residential gate. Properties within a few blocks of the ocean often see shorter lifespans because the salt moisture accelerates oxidation. Gates that are opened and closed more than ten times a day will wear hardware faster regardless of location. A yearly visual check catches most of the wear before it damages the operator.
For hinge pins and bushings, the answer is usually no: once the pin has worn down, the surrounding bushing is already elongated, and replacing just one side of that pair leaves you with slop. Rollers are the same story once the bearing inside the wheel starts to grind. What we can sometimes do is lubricate and adjust hardware that’s still within tolerance, which is why we only replace parts when the wear is measurable. Call (628) 227-2771 and we’ll look before we replace anything.
Most single-gate FAAC hinge and roller replacements are finished in two to three hours. A larger double swing gate with heavier hardware might take a half day. We quote the time honestly before the visit so you know what to expect, and we’ll send a technician who can explain the cause of the wear, not just the fix.
Our trucks in San Francisco carry the most common FAAC hinge pins, bushings, and roller wheels for the S418, S450H, 390, 740, and 844 series. For less common hardware configurations, we can usually source the part same week from our local Bay Area suppliers. We also stock Quality Aftermarket equivalents for homeowners out of warranty who’d rather keep the cost down without sacrificing lifespan. If we don’t have the part in hand, we’ll tell you before we set the appointment.
