Decks · Cedar, composite, aluminum, pressure-treated

Decks built to last the seasons.

Four materials, one crew. We help you pick what fits your yard, your budget, and how often you actually want to stain it — then we build it to OBC.

From a simple ground-level platform to a multi-level cedar build with stairs and a covered section, we handle the full job: design, permits if needed, footings, framing, decking, railings if you want them. Most decks ship in 2–4 weeks once the design is signed off.

Real decks, not just brochure photos.

What we build

Single-level decks

Ground-level or close to it. Quick to build, no railings needed under 24″, opens up the yard.

Multi-level + stairs

Wraparound decks, raised platforms, stair runs. Layout solved before the first cut.

Covered + pergola combos

Roof structure, pergola overlay, or louvered roof — shade where you want it, sun where you don't.

Replacements + resurfacing

Existing frame still good? Replace just the decking + railings. Old frame failing? We tear out and rebuild.
