Why Ironworks Gate Co. Is SeaTac’s Preferred Gate Installation Company
We’ve been doing this work since 1984. That’s over 42 years of hanging gates that close square and stay closed, from Boeing-era ranches to the rental car lots that ring Sea-Tac International. Our Gate Installation in SeaTac crew knows the difference between a gate that needs a new operator and a gate that needs to be pulled out and started fresh.
SeaTac homeowners call us because we show up when we say we will, we price the job before we turn a bolt, and we put the guarantee in writing. Our 90-Day Done Right Promise, the Keystone Standard, means no paperwork, no arguing: if it’s not right, we come back and make it right. Every job.
Our technicians are background-checked, uniformed, and trained on nine automation brands - Linear, Viking, Ghost Controls, DoorKing, and five others - so the correct fix happens on the first visit. A live person answers our phones 24/7, not a voicemail tree, not an answering service. That’s how we’ve built our reputation in King County, one square deal at a time.
Our Gate Installation Services in SeaTac
Sliding Gate Installation
Sliding gates are often the only practical choice in SeaTac’s older neighborhoods. The 1950s-1970s single-family homes east and west of the airport corridor sit on modest lots with short driveways - sometimes barely 20 feet of clearance. A swing gate would eat half that space or conflict with the sidewalk. We measure your run, fabricate or source a track-grade frame, and install operators like the LiftMaster LA500 with galvanized hardware built for marine humidity. At that 1960s ranch on South 170th Street, we replaced a heavily-patched wood-frame swing gate that had swollen so badly from SeaTac’s 38 inches of annual rain it couldn’t latch. The owner’s original chain-link slider, installed during a Port of Seattle noise-mitigation retrofit in 2006, was seized from rust. We retrofitted a heavy-duty sliding gate with a LiftMaster LA500 slide operator, using a galvanized track to withstand the marine humidity, and custom-fit it within the short 20-foot driveway to meet the city’s zero-clearance requirement.
Swing Gate Installation
When the lot allows, a swing gate is the simpler, quieter option. We install both single and double swing configurations, always checking your driveway grade and the setback from Military Road South or whatever street you face. SeaTac’s persistent damp means we spec stainless or galvanized hinges as standard, not as an upcharge. We also check your existing posts - many original wood posts from the Boeing housing era are rotted below grade, and hanging a new gate on a bad post is a waste of your money. If the post is sound, we’ll tell you. If it’s not, we’ll tell you that too, and we’ll price the replacement upfront.
Security Gate Installation
SeaTac’s commercial gate work is unlike anywhere else in King County. The airport economy means long-term parking lots, hotel shuttle entrances, rental car facilities, and cargo access roads that run 24/7. These are heavy-cycle operators, not residential toys. We install and automate security gates with industrial-grade equipment - FAAC and DoorKing are common choices for this workload - and we size the operator to the duty cycle, not to the budget. A gate that fails at 2 a.m. with a shuttle bus full of passengers costs more than doing it right the first time.
Pedestrian Gate Installation
Walk gates get overlooked until they sag or the latch quits catching. We install pedestrian gates that match your driveway gate or stand alone, with proper jamb depth and hardware that won’t rust solid in SeaTac’s wet winters. Many homeowners in the 98158 area add a pedestrian gate when they’re replacing a full fence line, especially in the neighborhoods where Port-funded soundproofing retrofits included perimeter fencing that’s now end-of-life.

Trusted Brands We Service in SeaTac

For SeaTac customers, this means we don’t order parts and make you wait.

The right part, the right technician, the first time. That’s the standard we work to.
Common Gate Installation Problems We See in SeaTac Homes
- Rusted hinge pins on original chain-link gates. The 1950s-1970s homes east of the airport corridor still carry their original gates, and the hinge pins are rusted nearly solid from persistent marine humidity. The gate binds, misaligns, and often can’t accept an automatic operator until the hinges are cut out and replaced.
- Rotting wood gates from Port-funded retrofits. Legacy one-piece wood gates installed during Port of Seattle soundproofing programs around 2000-2010 are now rotting at the posts, swelling shut every wet season, and frequently have discontinued openers with no replacement parts available.
- Moisture-damaged control boards on commercial operators. Heavy-cycle automatic gates at airport parking lots and rental car facilities endure 24/7 operation. Control boards fail from moisture intrusion and sheer duty cycle, requiring industrial-grade replacement with brands like FAAC or DoorKing.
- Short driveways that rule out swing gates. SeaTac’s modest lot sizes and zero-clearance requirements often make slide-gate retrofits the only viable automatic option, especially on the older residential blocks where driveway depth was never generous.

FAQs - Gate Installation in SeaTac
Many Port-funded gates are now 15-25 years old and hitting end-of-life, so parts are often discontinued and the wood may be rotting at the posts. We can assess whether your gate is worth repairing or if replacement is the better value, and we’ll give you an honest answer either way. Call (833) 754-7503 for a free evaluation - estimates are free, and we offer a free second opinion on any written estimate you’ve already received.
Usually not. SeaTac’s modest lots and zero-clearance requirements mean most driveways under 22 feet need a sliding gate to meet code and function properly. We measure on-site and will tell you definitively what fits. Call (833) 754-7503 and we’ll come check - estimates are free.
SeaTac’s 38 inches of annual rainfall and persistent marine humidity drive moisture into operator housings and control boards year-round, accelerating corrosion and electrical failure. We spec sealed, marine-rated operators and galvanized hardware as standard for this climate, not as an upgrade. If your current operator is failing after wet weather, call (833) 754-7503 - we’ll diagnose whether it’s a repair or a replacement, and we’ll price it upfront.
Swelling is a humidity problem, not a latch problem. We see this constantly in SeaTac’s wet-season cycles. The real fix is either replacing the wood with a moisture-stable material (steel or aluminum) or installing a properly sealed and ventilated gate built with gap tolerance for expansion. Adjusting the latch just masks the symptom until next November. Call (833) 754-7503 for an estimate on a gate that actually closes in January.
Yes. SeaTac’s airport-adjacent commercial properties are exactly the workload we train for - 24/7 duty cycles, shuttle bus impacts, and moisture intrusion on control boards. We install industrial-grade operators from FAAC and DoorKing, sized to your actual traffic count, with preventive maintenance plans available. Call (833) 754-7503 - a live person answers 24/7, and we’ll schedule a site visit to spec the right system.
