We start each project by listening: material preference, layout goals, how you use your outdoor space. Then we frame it with Oregon‑rated lumber or steel, select fasteners built for the coastal/mountain climate, and finish with clean, lasting surfaces. We coordinate permitting with Oregon’s building codes and local municipality rules, so your deck is safe, solid—and ready for enjoy‑along.
Everything Included. No Guesswork.
What’s Included in Our Custom Deck Projects
From initial concept to the last baluster, we provide a full‑service deck build that’s customized to your property in Oregon. You pick finishes and form. We handle the structure, safety, and fine details.
Custom layout and design renderings tailored to your yard and home
Framing, footings and material selection built for Oregon’s climate
Finish choices: cedar, pressure‑treated, composite plus stairs and railings

Whether your home sits on a slope in Eugene or a flat lot in Salem, our team designs to match both land and law. We understand Oregon’s snow load zones, seismic considerations, and local railing height laws. We build to pass inspection the first time—no rework, no delays. And with material choices suited to wet winters and sun-soaked summers, your deck stays safe and beautiful year after year.

Natural Materials or Composite—We Build Both Right
Your Choice of Decking, Our Guarantee on Structure
We work with cedar, pressure-treated pine, and top composite brands like Trex and TimberTech. Whether you want the warmth of real wood or the low-maintenance ease of capped boards, we frame and fasten everything to perform in Oregon’s seasons. Balusters don’t wobble, treads don’t creak, and boards won’t cup or split. Our builds last—and they look good doing it.
We don’t drop a square onto your lot—we design around it. Our decks blend with your home’s lines, your door heights, and your landscape. From stairs that land naturally to platforms that maximize sun or shade, our decks feel intentional—not afterthoughts. We also coordinate colors, rail styles, and trim for a seamless look. [

Don't worry, we can help!
We don’t just install decks—we build structures that stand up to weather, use, and inspection. Our framing is overbuilt, our fasteners rated, and our finish clean.
Engineered plans and permitting included for most Oregon cities
Sloped drainage, stair safety, and hardware all meet code
Composite or wood options sealed and spaced for performance
We don’t hand you off to subs or make you coordinate contractors. Our in-house team designs, frames, builds, and finishes your deck—without gaps or handoffs. From first sketch to final rail cap, you deal with one builder. That means faster answers, tighter schedules, and better results.
These are the most common questions homeowners in Oregon ask us before building a custom deck.
Yes. We handle the entire permitting process, including engineering and local submission.
Composite and cedar are both great choices—cedar needs more maintenance; composite resists moisture and fading.
Most projects take 1–3 weeks depending on size, site, and permitting timelines.
