What railing style works best for narrow staircases?

Horizontal bar and cable systems often feel the most open, while vertical pickets create a more traditional look without overwhelming small spaces.

Can aluminum stair railings withstand coastal or high-moisture environments?

Yes. Aluminum does not rust, warp, or swell, making it ideal for both indoor and outdoor stairways in the Pacific Northwest.

Do you replace existing wood railings?

Absolutely. We can remove your old railing and install a new aluminum system in its place.

Why Aluminum For Stair Railings

The Pacific Northwest’s humidity, temperature shifts, and salt air can warp wood and corrode steel. Aluminum, however, stays strong and consistent year after year.

Rust-resistant: No peeling, flaking, or annual sealing required.
Strong yet lightweight: Ideal for long runs, open staircases, and multi-story homes.
Low maintenance: A quick rinse or wipe-down keeps it looking new.
Custom finishes: Match your railing to your flooring, trim, newel posts, or interior palette.

Our stair systems are engineered for durability and designed to complement both modern and traditional interiors.
