Fast, Reliable Gate Installation Across Fairfax
Gate installation in Fairfax typically runs $2,800–$7,500 depending on gate type, materials, and whether your driveway sits on a steep grade or level entry. Most Fairfax installations take one to three days, with Kevin handling the layout and post-setting personally. We’re familiar with the narrow winding driveways off Cascade Drive and the irregular hillside lots around Bolinas Ridge — we know the posts will fight you before the gate ever hangs. Call (866) 788-1265 for a free estimate; we’ll come measure your opening and check your grade.
Our Gate Installation team works Fairfax regularly — it’s a short run from our San Francisco base up through Marin, and we’ve installed gates on enough Fairfax properties to know the local headaches before we arrive. We don’t send salespeople. Kevin shows up, measures, and tells you straight whether your post footings will hold or whether Fairfax’s wet valley soil will eat them in ten years.
Why Ironclad Gate Repair Service San Francisco Is Fairfax’s Preferred Gate Installation Company
We’ve been installing gates in Fairfax for eleven years, and over 1,000 neighbors across the Bay Area have left verified reviews — 1,072 at last count, averaging 4.8 stars. That volume matters because it means we’ve seen the failure patterns before they happen. Fairfax customers specifically mention our upfront pricing and Kevin’s willingness to explain why a post needs to go deeper than the original contractor set it.
Response time to Fairfax is typically same-day or next-day for estimates. We’re not crossing the bridge from the East Bay or driving down from Sonoma — we’re based in San Francisco with regular Marin routes, so your appointment slot doesn’t get burned by bridge traffic.
Our local knowledge runs deeper than GPS. We know that a gate installed in August on dry Fairfax soil will look plumb and swing true, then lean six degrees by March after the valley’s 40–50 inches of annual rainfall saturates the footing. We set posts deeper, use concrete collars, and specify hardware that tolerates seasonal wood swelling. That specificity is why Fairfax homeowners call us back when they move to a new house in town.
Our Gate Installation Services in Fairfax
Driveway Gate Installation
Fairfax driveways are rarely standard. Between the craftsman cottages on narrow lots and the hillside cabins off Sir Francis Drake Boulevard, your driveway gate often needs to fit an odd width, clear a steep upslope, or swing without hitting a retaining wall. We measure twice, fabricate in-house if needed, and set posts with your specific grade in mind. A typical driveway gate installation in Fairfax runs $3,200–$6,800 for wood, $4,500–$8,200 for steel or aluminum with automation.
Pedestrian Gate Installation
Pedestrian gates in Fairfax see heavy use — they’re the daily entry point for homes where the driveway gate stays closed. We install pedestrian gates with self-closing hardware that actually works on sloped Fairfax walkways, not just on paper. Because Fairfax lots are often fenced with mixed materials (old redwood, newer cedar, sometimes chain link from a 1980s renovation), we match your new gate to existing fencing or replace the whole run if the posts are compromised. Pedestrian gates in Fairfax typically cost $1,400–$2,800 installed.
Swing Gate Installation
Swing gates are the most common request we get in Fairfax, and they’re also the most likely to fail if the post work is rushed. The Fairfax lean hits swing gates hardest — a single post carries the entire load, and when it rots at grade, the gate goes down hard. We use pressure-treated 6×6 posts set 36–42 inches deep in concrete, with gravel drainage at the base to slow the saturation that kills standard installations. On steep grades, we install adjustable hinges and sometimes recommend a double-swing configuration to reduce leaf weight per post. Swing gate installation in Fairfax: $2,800–$5,500 manual, $4,200–$7,500 with automation.
Sliding Gate Installation
Sliding gates work well on Fairfax’s narrow driveways where a swing gate would block the road or hit parked cars. The catch: sliding gates need level track, and Fairfax grades fight you. We install cantilever systems when the slope is too severe for ground track, and we fabricate custom posts and brackets in our shop to handle the side-load that uneven footings create. Sliding gate installations run $4,500–$8,500 in Fairfax, with the upper end covering cantilever systems on steep entries.

Trusted Brands We Service in Fairfax
We install and automate gates with equipment from FAAC, BFT, Linear, and Viking — four of the nine major brands we carry parts for. That parts inventory matters in Fairfax because a failed opener or control board shouldn’t mean two weeks waiting for a shipment from Los Angeles. We stock common FAAC and BFT control units, Linear actuator arms, and Viking slide gate operators, so most Fairfax automation projects don’t face parts delays. Kevin is certified on all nine brands including LiftMaster, DoorKing, and Ghost Controls, so whatever system your property currently runs, we can match it or upgrade without a full replacement.
Common Gate Installation Problems We See in Fairfax Homes
- Post rot at grade: Saturated soils rot pressure-treated posts from within, causing sudden gate collapse. On a steep, winding driveway off Cascade Drive, we replaced a rotted 4×4 post on a custom-fitted swing gate that had collapsed during the first heavy November storm. The post looked intact above ground but was hollow below grade, a classic Fairfax lean. We dug out the old footing, set a new post in concrete, and realigned the hinges with LiftMaster openers.
- Post settlement: Wet-dry cycling on steep, irregular lots heaves concrete footings out of plumb. Fairfax’s hillside cabins see this every spring — the gate that closed cleanly in October now drags in April. We install deeper footings with expansion joints and sometimes anchor bolts into bedrock when the grade allows.
- Hardware misalignment: Swelling wood from persistent moisture binds hinges and self-closing arms seasonally. We specify marine-grade hinges and adjustable self-closers that tolerate 1/4-inch seasonal movement without binding.
- Non-standard openings: Fairfax’s 1940s–1960s bungalows were built before standardized gate widths, so a 42-inch pedestrian opening or a 14-foot driveway span is common. We measure on-site and fabricate custom frames in-house rather than forcing a prefab gate to fit.
Pricing for Gate Installation in Fairfax, CA
| Gate Type | Manual Installation | With Automation |
|---|---|---|
| Pedestrian Gate | $1,400 – $2,800 | $2,200 – $3,800 |
| Swing Gate (single) | $2,800 – $5,500 | $4,200 – $7,500 |

These ranges reflect Fairfax’s market specifically — higher than inland Bay Area cities because of the grade challenges, custom fitting requirements, and the deeper post work we specify for wet-soil durability. Material choice moves the needle: cedar or redwood costs less upfront but requires more maintenance in Fairfax’s climate; steel or aluminum costs more initially but eliminates the swelling and rot issues. Every estimate we provide is free and itemized — post depth, concrete volume, hardware specs, and automation components listed separately so you see where your money goes. Call (866) 788-1265 to schedule.

FAQs — Gate Installation in Fairfax
They lean because the posts rot underground while the gate above looks fine — locals call this “the Fairfax lean.” Fairfax’s 40–50+ inches of annual rainfall, the highest in the Bay Area, saturates soil for months and hollows out pressure-treated posts at grade. We prevent it by setting posts 36–42 inches deep with concrete collars and gravel drainage. Call (866) 788-1265 if your gate is already leaning — we can assess whether the post is salvageable or needs replacement.
Yes, but usually with a cantilever system rather than ground track. Standard sliding gates need level track, and Fairfax’s steep grades make that impractical on many hillside lots. We fabricate cantilever brackets in-house to handle the side-load and uneven footings. Kevin will measure your grade during the free estimate and tell you whether cantilever or a swing gate makes more sense for your specific driveway.
We do, though many 1960s openers lack modern safety features and parts availability is shrinking. We service nine major brands and can often source or fabricate replacement components, but we’ll also give you an honest assessment of whether repair or a new FAAC, Linear, or Viking unit is the better long-term value. Most Fairfax bungalows benefit from upgrading to current safety standards while keeping the original gate character.
Typically 10–15 years in Fairfax’s saturated valley soil, often less if the post wasn’t set deep enough or if the concrete footing traps moisture against the wood. We see posts fail faster on north-facing slopes where sun never hits to dry the soil. Our installations specify deeper setting, concrete collars that shed water, and sometimes steel post sleeves for critical applications.
Metal gates eliminate wood swelling and seasonal binding, but they won’t stop post rot — the post still carries the load and still sits in wet Fairfax soil. We recommend metal gates paired with our deeper post specification, or sometimes steel posts set in concrete rather than wood. The combination removes both failure modes. Call (866) 788-1265 and we’ll walk through the options for your specific grade and exposure.
