Composite Decks Built for South Carolina’s Climate

Composite Deck Installation in South Carolina

Built to Beat the Heat and Humidity

Why South Carolina Homeowners Choose Composite Decking

Composite decking is engineered to handle what South Carolina weather throws at it. Unlike traditional wood, it won’t rot, splinter, or fade — even with full sun exposure and frequent summer storms. With minimal maintenance and decades-long warranties, composite materials offer unbeatable value. We install top-performing products like Trex and TimberTech in every region, from breezy coastlines to shaded backyards. Whether you’re replacing an old deck or starting fresh, this is the smart, lasting choice.

Style That Lasts. Performance That Pays Off.

What’s Included in Our Composite Deck Installation

We handle your entire composite decking project — from planning and permits to footings, framing, and final trim. Our team builds with moisture-blocking tape, hidden fasteners, and solid joist spans to ensure your deck performs long-term. Choose from a wide range of textures, colors, and board styles — including grooved edges, picture framing, and fascia wraps. Whether it’s a pool deck, wraparound porch, or multi-level platform, we build every detail to last.

Decking That Handles Salt Air, Heat & Storms

Composite Decks Designed for South Carolina’s Climate

From humid summers in Columbia to salty breezes in Charleston, South Carolina’s climate can destroy untreated wood decks in just a few years. That’s why we recommend composite materials for homeowners who want long-term performance. These boards resist mold, mildew, UV rays, and insect damage — without needing annual staining or sealing. We design every composite deck for airflow, drainage, and beauty, so it stays cool underfoot and stunning from every angle.

More Time Enjoying. Less Time Maintaining.

Low-Maintenance Doesn’t Mean Low-Quality

Today’s composite decks offer more than convenience — they deliver real curb appeal. With dozens of colors, grains, and trim options, your new deck will look and feel like natural hardwood — without the upkeep. No peeling paint. No splinters. No power washing every spring. Just rinse it off and relax. We build every surface to minimize maintenance while maximizing the lifespan of your outdoor investment.

Smart Choices. Strong Materials. Better Builds.

Why We Recommend Composite Over Traditional Wood

While pressure-treated wood remains a budget-friendly option, composite decking wins on nearly every long-term metric. It doesn’t warp, fade, crack, or rot. It’s cooler underfoot and backed by 25–50 year warranties depending on the product line. For homeowners who want peace of mind and a premium finish, composite delivers real value. It’s an upgrade that pays for itself in both time saved and years gained.
