Seattle is the largest market we serve, and Seattle lots are unlike anywhere else in King County: narrow, sloped, hemmed in by alleys and neighbors. Gate work here is about fitting a secure, automated entry into a tight footprint without tearing up the property. For Seattle properties where the goal is traffic control rather than a physical barrier, a barrier arm gate is the right tool: fast, reliable, easy to pair with access control and much less expensive to operate than a slide gate for high-volume entries.

FREE ESTIMATE
Between hillside driveways in West Seattle, Magnolia and Queen Anne, alley-loaded garages in Ballard and Capitol Hill and the flat industrial yards of SoDo and Georgetown, almost every Seattle project needs a custom-measured gate rather than an off-the-shelf panel. For Seattle HOAs and apartment communities we typically pair the barrier arm with a keypad or transmitter for residents, a visitor intercom or call box, and a free-exit loop, so residents never stop and visitors can be let in from a phone.

We work on craftsman and mid-century homes with short driveways, multi-family buildings that need controlled parking access, and warehouses, contractor yards and dispensaries in the industrial districts that need a commercial slide gate and access control. Barrier arms need power, loops and often a pedestal, so we coordinate the electrical and the pavement work in Seattle and schedule the install so the lot stays usable during business hours.
We also repair and replace barrier arms in Seattle that have been hit, worn out or outgrown, including retrofitting old operators to current LiftMaster equipment and adding loop detection where none existed.
A.D. Security Gates & Access LLC serves West Seattle, Rainier Valley, Beacon Hill, Queen Anne and every other Seattle neighborhood for barrier arm gate installation. Our Renton base puts us twenty to thirty minutes from most of Seattle by I-5 or I-405, so scheduling a site visit anywhere in the city is easy.
