SeaTac is built around the airport, and that shapes the gate work we do here: park-and-fly lots, hotel parking, rental and shuttle yards and air-cargo businesses that need barrier arms, commercial slide gates and access control that runs around the clock. A.D. Security Gate inspects automatic and manual gates, slide gates, swing gates and barrier arms across SeaTac, whether we installed them or not, and gives you a straight answer on repair versus replacement.

Most commercial sites are flat and paved, which makes them straightforward for barrier gates and cantilever slide gates, while the residential streets around Angle Lake, McMicken Heights and Bow Lake have a mix of flat and sloped driveways. For SeaTac HOAs and apartment communities, an annual gate assessment documents the condition and safety of a system that dozens of people rely on, supports budgeting for repairs and replacement and reduces liability by showing that safety devices were tested.

Besides the airport businesses, SeaTac has older single-family neighborhoods, apartment complexes along International Boulevard, and small industrial yards that all benefit from a gated, controlled entry. Most residential gate assessments in SeaTac take about an hour and commercial or community assessments one to two hours, and we can schedule them around closings, board meetings or budget cycles.
If the assessment shows your SeaTac gate is in good shape, we will tell you so and suggest a maintenance schedule. If it is not, we will show you the photos and explain the options in plain language.
We provide gate inspection and assessment across all of SeaTac, including Angle Lake, McMicken Heights, Riverton Heights, Bow Lake, and the surrounding SeaTac area. SeaTac is fifteen minutes from our Renton base, and we understand that airport-area businesses cannot have a gate down for long, so repair calls here are a priority.
