Decks and Porches
Built square. Built to last.
From simple backyard decks to wraparound porches and custom layouts with hot tub surrounds, built-in benches, or privacy screens, every project is designed for how you live. We use durable materials like Trex®, TimberTech®, cedar, and pressure-treated lumber—chosen to fit your budget and maintenance goals.
At Black River Builders, we listen, build it right the first time, and keep our word on price and schedule. No surprises—just honest work from a family crew proudly serving Rochester, Grand Mound, Oakville, Centralia, Chehalis, Tumwater, and surrounding Southwest Washington.
Materials and Design
Solid Foundations
Every deck starts with proper framing—concrete footers, pressure-treated lumber sized correctly for span distances, level construction, and code-compliant fastening. We don't cut corners. Your deck is only as good as what's underneath.
Quality Deck Materials
We work with composite options like Trex® and TimberTech® for low-maintenance durability, or natural materials like cedar and pressure-treated lumber for traditional appeal. Each has trade-offs in cost, upkeep, and longevity—we'll help you choose what fits your goals.
