Low-Maintenance Decks Built for the Oregon Climate

Composite Deck Installation in Oregon

Why Choose Composite Over Traditional Wood?

The Benefits of Composite Deck Installation

Composite decking is engineered to provide durability and aesthetic appeal without the maintenance of cedar or pressure-treated wood. In Oregon, where moisture and temperature swings are common, composite decks resist rot, mold, and fading far better than wood can. This makes them ideal for both year-round living and investment value. Our crews install premium products from trusted brands like Trex, TimberTech, and Fiberon, offering various colors, textures, and grain patterns to complement your home's exterior. You’ll also benefit from capped composite boards that lock out moisture and come with extended warranties.

What You Can Expect from Your Composite Deck

Every composite deck we build is crafted for long-term performance and homeowner peace of mind. We take time to prepare solid footings, proper framing, and hidden fasteners that ensure clean aesthetics and structural integrity. From stairs to skirting, railings to recessed lighting, our builds are fully customizable and installed with care by licensed professionals. Homeowners across Oregon appreciate that composite decks don’t just look amazing — they hold up beautifully through wet seasons and sun-drenched summers alike.

Decks That Elevate Your Home and Lifestyle

Stylish, Safe, and Built for Everyday Living

Whether you’re entertaining friends or relaxing with family, a composite deck gives you a clean, secure space to enjoy Oregon’s natural beauty. These decks don’t splinter, peel, or warp — even when exposed to rain, snow, or heat. We help you choose the right layout, board style, railing design, and add-ons like integrated lighting or drink rails. Want built-in seating or planter boxes? No problem. From a cozy backyard patio to a sprawling rooftop entertainment space, we make composite decks that feel like an extension of your home — only better.

Questions About Composite Decking?

Oregon Homeowners Ask Us These All the Time

Here are the most common questions we get from clients considering composite deck installation — plus straightforward answers to help you decide what’s right for your home.

How long does composite decking last in Oregon?

Most composite brands offer 25–50 year warranties. With proper installation, your deck can easily last decades without major maintenance.

Is composite decking more expensive than wood?

Yes upfront, but it saves money long-term. You won’t need to sand, stain, seal, or replace boards nearly as often as wood.

Do composite decks get slippery when wet?

High-quality composite decking includes textured surfaces for better grip, making it safe even in rainy conditions common in Oregon.

Can I add composite decking to an existing wood frame?

Sometimes, yes. We inspect your existing framing first to ensure it’s structurally sound and compatible with composite material requirements.
