Deck Extensions & Re-Decking in Vermont

New Life for Your Old Deck

The Benefits of Re-Decking & Extensions

Not every aging deck needs to be torn down. If your framing is still solid, re-decking gives you a clean, safe surface without the cost of a full rebuild. And if your deck feels too small, a well-designed extension can double its functionality. We inspect your substructure, reinforce where needed, and replace surface boards, railings, or stairs with modern materials. Whether it’s wood or composite, the upgrade is fast, cost-effective, and built to last in Vermont’s challenging climate.

Smart Upgrades, Built Strong

What’s Included in Our Re-Decking & Extension Services

Every deck is different, and so is every upgrade. We start by evaluating your existing posts, beams, and joists for structural integrity. For re-decking, we remove old boards, tighten hardware, and lay new surface materials with modern fasteners. For extensions, we match elevations, add framing, and blend materials for a seamless look. Railings, stairs, and fascia are also upgraded as needed. The result is a safer, stronger, and better-looking deck—all without starting from zero.

Built for Vermont Conditions

Engineered for Longevity in Tough Weather

Vermont winters and wet springs are hard on outdoor structures. That’s why our re-decking and extensions include moisture barriers, upgraded flashing, and stainless or coated fasteners to prevent long-term issues. We also assess footings and beam connections to ensure your expanded or resurfaced deck holds up under snow load and freeze-thaw movement. Whether you’re switching to composite or keeping natural wood, we install with climate-resilient practices you can trust.

Thoughtful Design That Blends

Extensions That Match Style and Structure

When extending your deck, we don’t just tack on extra boards. We ensure the new addition aligns with your existing layout, railing design, and home architecture. Our team works with your current materials—or helps you upgrade them—for a seamless look. Transitions are carefully planned, elevations are leveled, and framing is reinforced for stability. Whether you want a wider lounging area, a new grilling zone, or stairs down to a patio, we design with both function and aesthetics in mind.

Our Process Keeps It Simple

From Inspection to Upgrade, We Handle It All

We start with a detailed inspection of your existing deck to determine if re-decking or expansion makes sense structurally. If it does, we create a plan for materials, layout, and budget. Once approved, we handle demo, framing, install, and finishing—plus cleanup and optional staining. Most projects are completed in a few days. We’ll walk you through every step and make sure your new space looks great, feels solid, and meets all Vermont building codes.
