Need more room for grilling, dining, or entertaining? We design and build seamless deck extensions that match your existing structure. Whether you want a platform for a hot tub, a new stair set, or a wraparound section, we engineer every addition to blend with your layout. Our extensions are framed to code, properly flashed, and built to last in North Carolina’s climate.
If your deck frame is solid but the surface looks worn, re-decking is the answer. We remove old boards, check for framing issues, and install new decking—wood or composite—over your existing structure. It’s faster than a full rebuild and more affordable. Re-decking updates the look, improves safety, and adds years of life to your outdoor space.
Replace old boards with composite or treated lumber
Inspect and reinforce existing substructure
Update railings, stairs, and fascia as needed

Many older decks don’t meet current NC building codes—especially when extended or resurfaced. We inspect for proper joist spacing, ledger attachment, and railing height before starting. Then we build or replace components with modern code in mind. Whether you're adding 100 square feet or just new steps, your deck will be safe, secure, and permit-ready

When extending or re-decking, choosing the right material makes all the difference. We install long-lasting composite decking (Trex, TimberTech, Fiberon), naturally beautiful cedar, or cost-effective pressure-treated pine. Our team helps you match or upgrade your current deck for a seamless finish—and we explain what maintenance each option requires in North Carolina’s weather.
Deck extensions come in all shapes and sizes—our job is to make them blend. Whether you want a flush platform off your living room, a stair landing to reach your yard, or a wraparound addition that follows your home’s footprint, we’ll design it to fit. We align the framing, match the material, and ensure transitions are smooth, strong, and up to code.

Faster Than a Full Rebuild: Save time and cost by reusing what’s solid.
Engineered to Blend In: Seamless transitions and matched materials.
Custom Fit Add-Ons: Built for grilling, stairs, hot tubs, or furniture zones.
Surface-to-Structure Checks: We inspect framing before extending or resurfacing.
Upgrade or Match Materials: Add square footage or re-deck with premium finishes.
Don't worry, we can help!
We start with a site visit to assess framing condition and layout options. Then we develop a detailed plan that includes all new dimensions, materials, and estimated timeline. During the build, we communicate clearly—especially when tying into existing structures. Whether we’re adding 3 steps or re-decking 300 square feet, you’ll always know the next step.

Fast, clean work with minimal disruption to your yard
We’ve extended and re-decked structures in every kind of setting—from narrow city lots in Charlotte to wide-open suburban yards in Cary. We understand the slope, soil, and permit considerations in each region. That means smarter design, better timelines, and more durable builds. If your current deck isn’t cutting it—we’ll make it bigger, stronger, and better.
Here’s what homeowners across North Carolina ask us most about adding onto or re-surfacing their decks.
Can you match the look of my existing deck during an extension?
Yes. We match materials, board size, color, and railing styles for a cohesive result.
How do I know if my frame is good enough for re-decking?
We perform a detailed inspection. If framing meets code and is rot-free, re-decking is a great option.
Absolutely. We can upgrade to composite if your frame spacing supports it—or adjust it if needed.
Will I need a permit for deck extensions?
In most cases, yes. We handle all permitting and code compliance for you.
