East Tennessee summers were made to be spent outside. Sunflower Contracting LLC builds custom decks, covered porches, and outdoor spaces designed for the way your family actually uses them.

Custom Decks and Outdoor Spaces in Greeneville and East Tennessee

In East Tennessee, the outdoors is part of the home. Greeneville's mild springs, warm summers, and colorful fall seasons make a well-built deck or covered porch one of the highest-use spaces on your property for eight or nine months of the year. Sunflower Contracting LLC builds outdoor living spaces that hold up to the Tennessee climate β€” properly flashed against the moisture that comes with mountain weather, engineered to handle the snow loads we occasionally see in Greene County winters, and built with materials chosen for long-term performance rather than short-term price.

Whether you want a straightforward ground-level deck off the back door, a multi-level structure with built-in seating, a screened porch that keeps the bugs out while keeping the views in, or a fully equipped outdoor kitchen for entertaining, we handle the entire project from permit to punch list. Halina and Jason Mann manage every build personally β€” you won't be handed off to a subcontractor crew you've never met. Every deck we build is inspected and code-compliant with Greene County requirements, which means no surprises when it's time to sell your home.

Material selection matters out here. We work with pressure-treated lumber, cedar, and composite decking systems that perform well in East Tennessee's humidity cycles. Composite materials from quality manufacturers have come a long way β€” lower maintenance, better color stability, and longer warranties than wood alone. We'll walk you through the real tradeoffs for your specific budget and how the space will be used, so you end up with a deck that still looks right ten years from now, not one that's cupped and greying in five.

Decks & Outdoor Living -- Common Questions

How much does a deck cost in East Tennessee?

Pressure-treated wood decks run $35-$55 per square foot (materials and labor). Composite or PVC decking runs $70-$130 per square foot. A typical 12x16 deck with composite decking and built-in bench seating runs $18,000-$30,000 depending on site prep and detail complexity. We provide a specific number based on your site and design -- not a range that grows after signing.

Do I need a permit to build a deck in Tennessee?

In most East Tennessee jurisdictions, decks under 200 square feet and under 30 inches above grade may not require a permit. Decks over those thresholds typically require a permit. We handle permit applications as part of our standard process -- you don't manage the paperwork.

What decking material do you recommend for the Tennessee climate?

It depends on your priorities. Pressure-treated lumber is the most budget-friendly and performs fine with regular maintenance. Composite decking (Trex, TimberTech) costs more upfront but eliminates annual sealing and resists moisture well in our humid climate. PVC is the most durable and lowest maintenance. We advise based on your budget and how much maintenance you want to commit to -- not on which product has the highest margin.

How long does it take to build a deck?

A typical wood or composite deck takes 2-4 weeks from site prep to final trim. Larger or more complex decks (multi-level, built-in features, integrated landscaping) take longer. We give you a firm completion date at the estimate -- not a vague range that could mean anything.

Can you extend an existing deck or replace worn boards?

Yes. We regularly work with existing deck structures -- extending them, replacing damaged boards or railings, or rebuilding sections that have structural issues. We assess the existing structure before recommending scope so you're not paying for more than you need.
