Deck Extensions & Re-Decking in Colorado

Custom Extensions to Fit Your Home and Yard

Deck Expansions for More Living Space

Adding onto an existing deck is a cost-effective way to gain more outdoor living space without starting from scratch. We design and build extensions that match your home’s architecture and seamlessly connect to your current deck. Whether you need a larger dining area, extra seating space, or a full wraparound addition, our extensions are engineered for safety, durability, and visual harmony.

Replace Old Boards with Modern Materials

Re-Decking: A Fresh Start Without a Full Rebuild

If your deck’s structure is sound but the surface is worn, re-decking is the smart solution. We remove old boards and install new cedar, pressure-treated lumber, or premium composite materials. This process gives your deck a brand-new look and feel—without the cost of tearing down the frame. Many Colorado homeowners choose composite re-decking for its durability and low maintenance.

Enhancing Every Part of Your Deck

Upgrade Railings, Stairs, and Details

Re-decking and extensions are the perfect time to update more than just the surface. We can replace outdated railings with modern wood, composite, or metal systems, rebuild stairs for safer access, and add trim details for a finished look. Whether you want a fresh aesthetic or improved safety, these upgrades transform your deck into a space that feels brand-new from top to bottom.

Choose the Material That Fits Your Needs

Wood or Composite Options

Re-decking gives you flexibility to upgrade materials. Many homeowners in Colorado choose composite decking for its long lifespan and minimal upkeep. Others prefer the warmth of cedar or the affordability of pressure-treated lumber. We’ll help you compare options for durability, appearance, and budget—so your re-decking or extension project delivers exactly what you want.

Ensuring Your Deck Frame Is Safe and Strong

Structural Checks Before We Build

Before we extend or resurface, our team inspects the existing structure to confirm it meets code and can handle additional weight. We reinforce or replace any weak framing, upgrade hardware, and pour new footings if required. This ensures your upgraded deck isn’t just beautiful—it’s safe, sturdy, and built to last through Colorado’s demanding climate.

Cost-Effective Ways to Improve Your Deck

Re-decking and extensions are budget-friendly alternatives to a full replacement. Instead of tearing down and rebuilding, we reuse existing structures when safe, add square footage where needed, and upgrade finishes for a brand-new look. This approach saves money while delivering impressive results that add value to your home.

  • Lower cost than a full rebuild

  • Expands usable outdoor space

Transforming Old Structures into Modern Spaces

Ideal for Aging or Outdated Decks

Many Colorado homes have decks that are structurally sound but dated or weathered. Re-decking allows you to upgrade to modern materials, fresh railings, and stylish finishes without starting from scratch. Deck extensions expand functionality, giving you space for outdoor kitchens, dining areas, or larger gatherings. Together, these upgrades make an old deck look and perform like new.
