SeaTac has grown around Sea-Tac Airport and light rail since incorporating in 1990. Optima designs, permits, and builds custom composite and cedar decks, backed by a 4-year workmanship warranty and 0% financing for 24 months.




Most deck failures start where you can't see them. Moisture works into the ledger board where the deck meets the house, into the tops of the joists, and around fasteners. By the time boards feel soft, the damage has usually spread. On older homes, the original attachment and flashing are often the weak point.
When we look at an existing deck, we check the ledger and flashing, post bases and footings, joist condition, and railing posts. Then we tell you plainly whether it's sound enough to restain or needs to be replaced. If it needs replacing, we handle the design, permits, and construction in one project, with stainless steel fasteners throughout and a 4-year workmanship warranty.

Cedar remains a favorite for SeaTac homeowners who want natural warmth and a classic look. Our crew sources quality boards, builds a sturdy frame suited to our wet climate, and finishes each deck so the wood ages gracefully for years to come.

Composite decking gives SeaTac families a low-maintenance option that resists moisture, fading, and splintering year-round. We install Trex and TimberTech composite decking, plus MoistureShield and Dasso XTR options with proper spacing and support, so your deck handles airport corridor weather without constant upkeep.

Every project in our gallery was designed and built by Optima's own crew, not subcontracted out. Browse recent decks completed across SeaTac to see the range of styles, railing options, and finishes we've delivered for neighbors nearby.
A deck rarely fails all at once. Small issues build quietly underneath the surface until they turn into real safety concerns. Knowing what to watch for helps SeaTac homeowners catch problems early, before a simple repair turns into a full replacement.
Optima holds an A+ rating with the Better Business Bureau, earned through consistent follow-through on every project we take on. SeaTac homeowners can check our standing directly with the BBB before hiring, and every credential below backs up what that rating represents in practice.
Here's what that commitment looks like in real terms:
Optima isn't a regional chain running crews through SeaTac on a rotation. We're a family-owned business, and that shows up in how closely we stay involved with every project from the first call to the final walkthrough.
Optima was founded by people who wanted deck work done right, not rushed. That standard still shapes how we plan and build every SeaTac project today.
As an owner-operated business, Optima gives every client a dedicated project manager who stays with the job from estimate to handoff, so questions never go unanswered.
A dedicated project manager stays with your deck from the first estimate to the final walkthrough, so what you're promised at the estimate is what gets built. Questions go to one person, not a call center.
Being family-owned means decisions about materials, scheduling, and problem-solving happen locally, not through a corporate office states away. That keeps response times fast and solutions practical for SeaTac homes specifically.
Who shows up to build your deck matters as much as the materials used. Optima sends trained, uniformed crews to every SeaTac job so homeowners know exactly who's on their property and what to expect from start to finish.
Every SeaTac deck project starts with a free, no-obligation estimate, so you know exactly what to expect before committing to anything. There's no catch, no pushy follow-up calls, and no pressure to sign before you're ready. Here's what the process actually includes.
Once you reach out, here's what to expect:
Optima's crews work across SeaTac regularly enough to know how different neighborhoods handle weather, soil, and sun exposure differently, which shapes how we plan and build every deck. That local knowledge carries into nearby communities like Renton and Auburn as well.
Neighborhoods and nearby areas we build in:
A tired deck doesn't have to stay that way. Whether you're repairing what's there or starting fresh, the right crew makes the difference between a quick fix and a deck that actually lasts. Worn boards, loose railings, and faded finishes don't just affect how a deck looks; they affect how safely and often your family actually uses it.
Putting off repairs rarely saves money in the long run. Small issues left alone tend to spread, turning an afternoon fix into a weekend rebuild. Deciding now, whether that means a repair, a refinish, or a full replacement, puts you back in control of your outdoor space instead of reacting to it later.





Nothing speaks to the quality of our work better than the people we've built for. Browse real feedback from SeaTac homeowners who've worked with Optima from first estimate to finished deck, and see what they had to say about the experience.
We walk your property in person, taking note of slope, drainage, and layout while talking through what you actually want your finished deck to look and feel like.
You choose the style, railing type, and finish that fit your home, with our team offering honest guidance on what holds up best in SeaTac's climate.
We pull the permits and handle HOA approvals and inspections, then build your deck on schedule, keeping your property as clean and accessible as possible.
We review the finished deck together, checking every detail against what was promised before considering the job complete and handing it over to you.
