We’ve been installing gates in Seattle since 1984, and we’ve learned that this city punishes hardware that isn’t specified for its exact conditions. The marine moisture, the clay soils that hold water, the freeze-thaw cycles that heave old concrete, and especially those steep residential grades in Capitol Hill, Queen Anne, Beacon Hill, and Fremont - they all demand something different from a standard flat-lot install. Our Gate Installation team doesn’t adapt a California spec and hope for the best. We measure the slope, test the soil drainage, and build for Seattle’s real conditions.
Why Ironworks Gate Co. Is Seattle’s Preferred Gate Installation Company
Forty-two years in business means we’ve installed gates on Seattle homes through three full generations of automation technology. We’ve replaced hand-forged strap hinges on 1910 Craftsman bungalows in Ballard and mounted Viking slide gate operators on new construction in Queen Anne. That depth matters when your 1920s gate posts are rotted at grade and the driveway drops 15% toward the street - we don’t guess, and we don’t subcontract to a generalist who’ll learn on your property.
Our technicians are background-checked, uniformed, and trained on nine gate-automation brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. We stock parts for all nine, so a Seattle customer isn’t waiting two weeks for a specialty hinge bracket or a slope-compensating operator arm. The job gets done in one visit, with the price settled before we turn the first bolt.
Every installation carries our 90-Day Done Right Promise - the Keystone Standard, written and with no paperwork to file. If it isn’t right, we come back and make it right. No arguing. That’s been our policy since 1984, and it’s why Seattle homeowners call us back when they move to a new house or recommend us to their neighbors.
We answer our own phones. Not an answering service, not a callback queue. A live person, 24/7. When your gate won’t close on a Friday evening in Seattle, you talk to someone who can dispatch a technician, not someone taking a message for Monday morning.
Our Gate Installation Services in Seattle
Driveway Gate Installation
Seattle’s narrow lots and alley-loaded garages make driveway gate installation a tight-space discipline. In Ballard and Fremont, we regularly work with clearances under 14 feet, where a standard swing arc won’t fit and a sliding gate needs custom track geometry. We measure twice, fabricate once, and coordinate with Seattle’s SDOT permit requirements when the gate crosses a sidewalk or opens onto a street. Our driveway gates start at $2,800 for a basic single swing in steel or aluminum, with automated packages running $4,200-$7,500 depending on brand and access control.
Swing Gate Installation
Swing gates remain the most common request in Seattle’s older neighborhoods, but they’re also where slope problems show up first. A standard swing gate installed on a 15% grade will rack within two seasons as the downhill post settles or the uphill post heaves. We specify slope-compensating hinge brackets from Viking or FAAC, or we build a raked frame that keeps the gate plumb while the posts follow the grade. In Queen Anne, we’ve replaced dozens of “simple” swing gates that failed because the original installer ignored the slope. Our swing gate installations run $2,800-$5,500 for manual, $4,500-$8,500 automated.
Sliding Gate Installation
Sliding gates solve the clearance problem on Seattle’s steepest lots and narrowest alleys. The gate travels parallel to the fence, so you don’t need swing radius - just straight track run equal to the opening width plus 18 inches. In Capitol Hill townhomes with 10% grades and parking pads barely wider than a Subaru, a sliding gate is often the only practical choice. We install Linear and FAAC slide operators with battery backup for power outages, which matter in Seattle’s winter windstorms. Sliding gate installations typically run $5,500-$8,500 depending on track length and automation.
Pedestrian Gate Installation
Pedestrian gates in Seattle see heavy use - they’re the daily entry point for gardeners, dog walkers, and deliveries while the driveway gate stays closed. We build them with marine-grade stainless steel hinges and adjustable latches that tolerate the seasonal movement of wet cedar posts. In the 98115 and 98117 ZIP codes, where Craftsman homes line every block, we match pedestrian gate styles to existing fence lines so the new install doesn’t look like an afterthought. Pedestrian gates run $850-$2,200 installed.
Security Gate Installation
Seattle’s urban density and alley access patterns make security gates a priority for many homeowners. We install keypad and telephone entry systems, rolling-code remote access, and smartphone-compatible operators from LiftMaster and DoorKing. For narrow alley access in Ballard or Fremont, we favor Linear’s compact slide operators with integrated loop detectors - they don’t require the overhead clearance of swing arms and they detect vehicles without the driver pressing a button. Security gate packages with access control start at $6,500.
Double Gate Installation
Double gates split the opening, reducing the swing arc on each leaf - useful when you’re tight on clearance but want the traditional look of a swing gate. In Seattle’s 98114 and 98116 ZIP codes, where lots are narrow but homeowners want curb presence, double gates in aluminum or steel with automated synchronized openers are a popular compromise. We use BFT’s dual-operator kits with electronic synchronization so both leaves move as one unit. Double gate installations run $4,200-$7,800.

Trusted Brands We Service in Seattle
We maintain factory-trained certification on nine gate-automation brands and stock critical parts for each in our local inventory. For Seattle’s wet climate, we specify Viking’s sealed gearboxes and FAAC’s oil-bath operators - designs that tolerate constant atmospheric moisture without the corrosion failures we see in lesser units. BFT’s hydraulic swing operators handle high-cycle use on steep grades without the thermal shutdown problems that plague residential-grade openers. Because we stock locally, a failed operator arm or a cracked hinge bracket doesn’t mean two weeks of an open gate. Most Seattle customers get same-day or next-day parts replacement.
Common Gate Installation Problems We See in Seattle Homes
- Wood gate posts rot at grade from Seattle’s 150+ wet days and driveway runoff pooling at fence lines. By the time the gate sags or won’t latch, the post is hollow at ground level. We replace with steel posts or pressure-treated timber set in 48-inch concrete footings with gravel drainage.
- Pre-1940 concrete footings lack rebar and crack in freeze-thaw cycles. In Capitol Hill and Queen Anne, we regularly find original footings from the 1910s-1920s that have heaved six inches or more. New installations need helical tie-down anchors or deeper footings to prevent repeat failure.
- Sloped driveways rack standard gates within two years. A gate installed square on a 15% grade binds against the latch post as the downhill side settles. Slope-compensating hinges or raked frames are essential - not optional upgrades.
- Marine moisture corrodes ferrous hardware year-round, not just in winter. Hinges, latches, and operator mounting brackets that would last a decade inland need stainless or hot-dip galvanized specification in Seattle.

FAQs - Gate Installation in Seattle
The downhill gate post settles or leans under gravity and wet-soil weakening, while the uphill post may heave in freeze-thaw cycles. The gate frame racks out of square, so the latch no longer aligns with the strike plate. Resetting the latch is a temporary fix; the real solution is re-plumbing or replacing the post with a slope-set footing and adding slope-compensating hinge brackets. Call (833) 754-7503 for an inspection - estimates are free.
No - in nearly every case we’ve seen, the post bases are rotted at or below grade from 100 years of Seattle moisture, and the original concrete footings lack rebar and have cracked or heaved. Bolting a new gate to compromised posts guarantees failure within one season. We replace with steel posts in 48-inch reinforced footings, which adds $1,200-$2,400 to the job but gives you a gate that stays true. Call (833) 754-7503 and we’ll assess what’s salvageable.
Linear’s compact slide operators or FAAC’s in-ground swing operators - both minimize overhead and side clearance requirements. Linear’s slide units need only 6 inches of side room beyond the track, and FAAC’s 770 series installs in a foundation box flush with the driveway, with no visible operator arm. We stock both and can demonstrate the difference. Call (833) 754-7503 to schedule a site evaluation.
A sliding gate is usually the better choice. It doesn’t swing into the slope or require clearance arcs that may intrude on sidewalk or neighbor property. The track runs level regardless of driveway grade, and the operator doesn’t fight gravity on every cycle. For a 10% grade with limited clearance, we typically specify a Linear slide operator with battery backup. Swing gates on that slope need raked frames and slope hinges - doable, but more complex. Call (833) 754-7503 and we’ll measure your site.
We set gate post footings 48 inches minimum in Seattle’s clay soils, with rebar reinforcement and gravel drainage at the base. Pre-1940 footings were often 24-30 inches and lacked rebar, which is why they fail. In areas with poor drainage or known heave problems, we add helical tie-down anchors to prevent vertical movement. This exceeds what many installers specify, but we’ve seen too many callbacks from shallow footings to cut that corner. Call (833) 754-7503 for a free estimate.
