AfterFast, Reliable Gate Installation Across Sausalito
Gate installation in Sausalito runs $1,800 to $6,400 for most residential work, and the biggest variable isn’t the gate itself - it’s whether the post footings can handle salt fog and hillside fill that shift every winter. We’ve been fixing and hanging gates in Marin since 2001, and Sausalito’s combination of bay spray and steep terraced lots creates problems you won’t find ten miles inland. Call (877) 610-2993 and you’ll get Hal or a live person who knows the difference between a Banana Belt hillside lot and a flat Richardson Bay dock, because that difference determines how we build the footing and what hardware we spec.
Every Gate Installation we do starts with a free on-site look at your existing posts, your soil, and how the gate will be used. No charge to come out if you’re in Marin. We quote the full price before any work starts, in writing, and that’s the price you pay.
Why Gatewood Fence & Gate Is Sausalito’s Preferred Gate Installation Company
Hal Gatewood has been owner-operated since 2001. His name is on the shop, his address is published, and his license number is something you can look up. You’ll see him at the hardware store. You’ll see his truck on Bridgeway. That’s the kind of accountability that matters when you’re spending four or five thousand dollars on a gate that needs to work for twenty years.
Sausalito customers call us because we show up when we say we will, and because the person who hangs the gate is the same person who answers the phone when you call about it later. Our 90-Day Done Right Promise is stamped in writing on every job. If something isn’t right, one call brings us back. No runaround, no arguing about whose fault it is.
We’ve done enough work on the hillsides above Bridgeway and along the floating-home docks to know that a gate that holds square on a flat lot in Mill Valley will bind and burn out a motor within two seasons in Sausalito. That local knowledge gets baked into every footing, hinge, and operator we install.
Our Gate Installation Services in Sausalito
Driveway Gate
Most driveway gates in Sausalito sit on grades that require either a bottom-roller setup or an uphill-swing configuration. The 1940s through 1970s homes terraced into the hills above Bridgeway rarely have a level approach, and hanging a gate as if they do is how you get a gate that drags on the uphill corner and strains the motor. We hang the gate to swing true to the grade, not to the bubble level. A typical driveway gate installation in Sausalito runs $2,800 to $6,400 depending on width, material, and how much concrete work the footings need.
Pedestrian Gate
Pedestrian gates in Sausalito face the same salt fog the driveway gates do, just smaller. We build the frames and footings with the same corrosion-resistant hardware, because a pedestrian gate that rots at the hinge post is just as stuck as a driveway gate. You’ll pay roughly $1,200 to $2,600 for a well-built pedestrian gate with proper galvanized or stainless hardware that won’t seize up after a winter of bay spray.
Sliding Gate
Sliding gates make sense on Sausalito hillside lots where a swing gate would need to fight gravity on every cycle. The trade-off is that sliding gates need clean track and a solid concrete pad, which on a terraced cut-and-fill lot means pouring a level rail bed. Most sliding gate installations in Sausalito run $3,200 to $6,800, including the track bed, cantilever hardware, and a gate motor sized for the slope.
Swing Gate
Swing gates on Sausalito’s hillside terraces fail at the hinge post more than anywhere else in Marin. The clay-heavy fill under those terraced lots saturates every winter, shifts, and pulls the post a degree or two out of plumb. That’s enough to burn out a gate motor every spring. We pour deeper footings than a flat-lot install would use, and we spec hinges that can be shimmed for adjustment years down the road. A swing gate installation in Sausalito typically costs $2,600 to $5,800, with the footing work being the part that stops post-lean before it starts.

Trusted Brands We Service in Sausalito
We install and service FAAC, BFT, Linear, and Viking gate operators, plus a handful of others. We stock common control boards, safety photocells, and hinge hardware locally, so when your Sausalito gate goes down we’re not waiting on a shipment from three states away. If your existing operator is a brand we service and the motor is still good, we’ll tell you that and retrofit rather than replace. Hal has never been one to swap a $900 board because a $12 limit switch failed.
Common Gate Installation Problems We See in Sausalito Homes
- Hinge post rot at the base from salt fog. Wrought iron and untreated mild steel posts within 500 feet of the bay corrode through in three to five years. We see it all the time along Bridgeway and up in the Banana Belt - the post looks fine above ground, and below the soil line it’s Swiss cheese.
- Post-lean on hillside fill after winter rain. Clay-heavy fill under Sausalito’s terraced lots swells when saturated. The gate post moves a degree or two, the gate drags, the loop detector trips randomly, and the motor overheats. Flat-valley installers misdiagnose this as a sensor problem. It’s a footing problem.
- Weld cracking from corrosion stress. Mild steel gate frames welded without galvanizing or proper coating develop corrosion at the welded joints first. In Sausalito’s salt air, that happens in under five years. We see 1980s gates on the hills above downtown with welds that have rusted through completely.
- Floating-home dock gate hardware seizing from salt water exposure. The Richardson Bay houseboat community deals with fresh water, salt water, and constant motion. Standard residential gate hardware seizes or breaks when the dock flexes with the tide. Dock gates need stainless or aluminum framing and hardware built to move.

Why Sausalito’s Salt Fog and Hillside Fill Change How We Install Gates
Here’s the thing most gate companies won’t tell you: a gate hung in Sausalito differs from the same gate hung in San Rafael because the environment demands different materials and different footings. The salt fog that rolls through the Golden Gate almost daily gets driven into every piece of exposed metal on a gate. Untreated wrought iron lasts under five years here. Powder-coated steel that looks perfect ten miles inland blisters and pits within two or three seasons within sight of the bay. So we specify galvanized posts, stainless hinge pins, and powder coating rated for marine exposure. It costs more up front. It’s cheaper than replacing the gate every four years.
Then there’s the hillside problem. The bulk of Sausalito’s residential stock sits on terraced cut-and-fill lots from the 1940s through the 1970s. The fill under those terraces is clay-heavy and shifts every winter when the rain saturates it. An automated swing gate gets a post pulled a fraction of a degree out of plumb, the gate starts to bind, and the motor works harder until it burns out. This is why a flat-lot installer can hang a gate in Sausalito that looks fine for a year and fails by the second spring. We pour footings deeper, use galvanized anchor bolts, and spec hinges that can be shimmed as the fill settles. A gate that moves with the grade - just enough - lasts decades. A gate that fights the grade burns through motors.
Add in the Richardson Bay floating-home docks and you have an entirely separate category of gate work. A gate mounted on a dock needs to flex as the dock rises and falls with the tide. Standard rigid residential hardware will bind or tear itself apart as the floating platform moves. We use aluminum or stainless framing bolted to the dock structure, with hardware that allows for tidal movement. That’s not a standard spec from any gate catalog. It’s something you learn from working on Sausalito’s docks.

FAQs - Gate Installation in Sausalito
If the post is rotted at the base from decades of bay spray, saving it usually means pouring a new footing anyway - the steel below the soil line is compromised, and any band-aid fix fails within a year. If the post is solid but leaning from fill shift, we can sometimes plumb it, brace it, and reinforce the footing with additional concrete. We’ll tell you which one it is after we dig down and look. Call (877) 610-2993 for a free assessment.
In most cases yes, you can retrofit modern safety photocells and edge sensors onto an older operator if the motor and control board are still sound. The question is whether the operator you have is worth keeping. We service FAAC, BFT, Linear, and Viking, and if the motor is good, we’ll retrofit and save you money. If the motor is on its way out, we’ll tell you that too - before you spend on a retrofit that won’t last.
Dock gates get aluminum or stainless framing, marine-grade powder coating, and hinge hardware built to flex with tidal movement. Standard galvanized residential hardware corrodes and seizes within a couple of years in constant salt water exposure. We’ve hung enough gates on Richardson Bay docks to know manufacturers’ standard hardware isn’t rated for this environment, so we spec accordingly.
Nine times out of ten, it’s not the sensor. It’s the post leaning as the clay-heavy fill saturates, moving the gate out of alignment and tripping the loop detector erratically. We check the post plumb first, because replacing the sensor without fixing the post means you’ll replace it again next winter. Call (877) 610-2993 and we’ll diagnose it in one visit.
Hillside gates need hinge hardware that can be shimmed to correct post drift as the fill settles, plus the gate itself is often hung with a bottom roller to carry weight off the post. A flat-lot gate uses standard hinges and weight bearing straight down through the post. On a Sausalito hillside, standard flat-lot hardware lasts until the first wet winter, and then the gate binds and the motor starts working itself to death. We specify the right hardware from the start.
