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.

Deck vs. Porch
Which is right for your home?
The terms get used interchangeably, but there's a real difference—and knowing which one fits your needs can save you time and money.
Decks are outdoor platforms, usually elevated off the ground with open railings. They're perfect for homes with sloped yards, outdoor entertaining, or when you want a dedicated space for grilling and gathering. Decks work well when you need height (like matching a second-story door) or want full sun exposure.
Porches are covered structures attached to your home, typically at the front or back entrance. They're sheltered by a roof, which makes them usable in rain or strong sun—ideal for the Pacific Northwest. Porches create a transition space between indoors and outdoors and add classic curb appeal. Wraparound porches are especially popular for extending your outdoor season.
Which one should you choose? It depends on how you'll use the space. If you want wide-open entertaining with full sun, a deck makes sense. If you're looking for weather protection and a traditional front-of-home feature, a porch is the better fit.
We've built both for homeowners across Rochester, Centralia, Chehalis, and surrounding areas. The right choice comes down to your property's layout, terrain, and how you actually want to use the space.

Choosing the Best Deck Materials
When choosing between composite, cedar, and pressure-treated wood, it comes down to how you want your deck to look, feel, and age.
Composite decking like Trex® and TimberTech® combines wood fibers and polymers for a durable, low-maintenance surface that lasts 25–30 years. It’s ideal for homeowners who want long-term performance with minimal upkeep.
Pressure-treated lumber remains the most affordable option and can last up to 20 years with proper sealing and staining—but it requires consistent maintenance to prevent warping and splintering.
Western Red Cedar offers natural Northwest beauty and a classic wood feel. It’s moderately priced and locally sourced, but it needs regular care to preserve its color and strength.
Each option suits different priorities—budget, look, or maintenance commitment.
