More Space. Better Surface. Same Great Deck.

Deck Extensions & Re-Decking in West Virginia

Add On. Upgrade. Make It New Again.

Breathe New Life Into Your Existing Deck

If your current deck feels too small—or the surface boards are cracked or dated—you don’t need to start over. We offer full-service deck extensions and re-decking to improve what you already have. Our team inspects your framing, recommends safe and code-compliant upgrades, and matches your existing layout or adds square footage where it matters. Whether you want to switch to composite boards or create more space for dining and relaxing, we make it happen without wasting what’s still solid.

When to Extend. When to Re-Deck.

Smart Options for Growing Families & Aging Decks

Re-decking replaces your deck’s surface boards while keeping the existing frame—great when the bones are still strong. Extensions add new sections to give you more usable space. Both options can include upgraded railings, stairs, or lighting. We’ll inspect your current deck and help you decide what’s worth saving and what’s time to improve.

  • Re-decking saves time and money over full rebuilds

  • Deck extensions add square footage to fit your lifestyle

  • All materials installed to modern safety standards

Upgrade to Composite Without a Full Tear-Out

We Install Trex, TimberTech & More Over Existing Frames

If your frame is solid, we can replace old wood boards with low-maintenance composite. It’s called re-decking—and it saves you time and cost while upgrading your outdoor space. We inspect and reinforce the frame as needed, then install your choice of Trex, TimberTech, or other leading brands using hidden fasteners and matching trim. It’s a smart way to modernize your deck without starting from scratch.

Extend What You Already Love

Deck Add-Ons That Match and Flow Seamlessly

Want to add space for a hot tub? Extend your dining area? Wrap a corner to connect to the yard? Our extensions match your existing deck’s style, height, and materials—so it looks like it was always part of the plan. We adjust framing, add footings, and ensure everything ties into your current structure safely and smoothly. You’ll gain the extra room you need without compromising your home’s look.

New Railings, Stairs, and Safety Upgrades

Make Old Decks Safer, Stronger, and Easier to Use

Re-decking and extensions are a perfect time to upgrade railings, stairs, and lighting. We offer code-compliant railing systems in wood, composite, or metal, and build staircases that feel stable, not steep. Need lighting? We can add post caps or step lights for nighttime safety. We also install grab rails, landings, and wider treads for families and aging homeowners.

What’s Included with Re-Decking or an Add-On?

Every project starts with a detailed inspection. We check the footings, framing, ledgers, and rail connections to ensure your current deck can support the upgrade. Then we build your extension or re-surface with new decking, fasteners, and trim. Most projects include minor repairs, clean-up, and optional lighting or railing upgrades—all completed by the same crew.

  • All framing inspected and reinforced if needed

  • New decking installed with proper gapping and fasteners

  • Add-ons built to match existing height and layout

Want to Replace Boards Only?

Re-Decking with Composite or Pressure-Treated Wood

Board replacement is the simplest way to refresh your deck’s surface. If your frame is solid but your boards are cracked, splintered, or stained, we can remove and replace just the top layer. Choose from composite for low-maintenance performance or pressure-treated for a budget-friendly refresh. We’ll also inspect railings, tighten fasteners, and check for hidden hazards before we call it done.

Questions About Extending or Re-Decking?

FAQs About Upgrading Your Existing Deck

Here’s what homeowners often ask when deciding between deck extensions, board replacements, or a full rebuild.

Question 1: Can I switch from wood to composite during re-decking?

Yes—as long as the frame is solid, we can install composite boards over it. We’ll inspect and adjust as needed.

Question 2: Will the new part match my old deck?

Yes. We match wood grain, color, and layout—or upgrade the entire surface for a unified look.

Question 3: How long does a deck extension take?

Most additions are done in 1–2 weeks, depending on size and materials.

Question 4: Is re-decking cheaper than rebuilding?

Yes. If your framing is in good shape, re-decking costs significantly less than a full tear-out and rebuild.
