Security Gate fabricates and installs here, from north-end waterfront estates to hillside homes along Island Crest Way. A.D. Security Gate builds custom driveway gates, pedestrian gates, courtyard gates and estate entries for Mercer Island in welded steel, aluminum and steel frames clad in cedar or composite, in styles from traditional ornamental to clean modern.

Island driveways are often steep and short, dropping from the street to a waterfront lot, so we plan swing direction, opener placement and safety sensors around the grade and install cantilever slide gates where a swing gate will not clear. Custom fabrication is how we solve the hard Mercer Island entries: openings that are not square, driveways that curve or rise, pillars that were built before the gate was planned and clients who want a specific pattern, address plaque or lighting built into the gate.
FREE ESTIMATE
Mercer Island is almost entirely residential: waterfront and view estates, mid-century homes on wooded lots and newer custom builds, many with pedestrian gates, intercoms and access control tied into the home's security system. Custom gate projects in Mercer Island typically run three to six weeks from approved drawings to installation, depending on the design and finish. We keep you updated through fabrication and schedule the install around concrete cure time for the posts.
