Driveway Gate Buying Guide: Swing vs. Sliding vs. Cantilever (Seattle–Tacoma 2026)

Choosing a driveway gate in the Seattle–Tacoma area comes down to three main designs: swing, sliding, and cantilever. Each works best in different situations — slope, space, weather, and how often the gate cycles all matter. This guide breaks down how to choose, based on 800+ installations across the Pacific Northwest.

Swing Gates: The Classic Choice

Swing gates open like a door — single or double leaf. They're typically the most affordable design, have the fewest moving parts, and look elegant on wide, flat driveways.

Best for: flat or gently sloping driveways with room for the gate to swing inward.
Watch out for: steep upward slopes behind the gate and heavy snow — both can block the swing path.

Sliding Gates: Space-Savers for Tight Driveways

Sliding gates move sideways along a ground track, so they need almost no clearance behind the gate. They're the go-to when the driveway slopes up right after the entrance — very common in Seattle hillside neighborhoods.

Best for: sloped driveways, short setbacks, and properties where every foot counts.
Watch out for: the track needs to stay clear of gravel and debris to run smoothly.

Cantilever Gates: The Heavy-Duty Performer

Cantilever gates slide like a sliding gate but hang from a counterbalanced frame — no ground track at all. That makes them the most reliable design in Pacific Northwest weather (nothing to freeze or clog) and the standard for commercial and high-traffic entrances.

Best for: commercial sites, uneven ground, gravel driveways, and high daily cycles.
Watch out for: they need extra run-off space to the side and a stronger operator, so they cost more than a swing gate of the same width.

Quick Comparison

Budget: swing is usually the most affordable, sliding is mid-range, cantilever is the premium option. (Full pricing in our 2026 automatic gate cost guide.)

Sloped driveway: sliding or cantilever — swing gates fight the hill.

Rain, leaves & PNW weather: cantilever wins (no ground track); swing is close behind.

Commercial / truck traffic: cantilever, paired with an industrial-grade gate operator.

Don't Forget the Automation

Any of the three designs can be automated. The right gate opener depends on the gate's weight and cycle count, and access control (keypads, intercoms, app control) can be added to all of them. If you already have a gate that's struggling, a repair or operator upgrade is often cheaper than replacing the whole gate.

Which Gate Is Right for Your Property?
