More Space. Better Materials. Smarter Investment.
If your current deck is structurally sound but showing age — or simply not big enough — re-decking and extending are smart ways to get more from your outdoor space. We assess the existing frame, confirm load-bearing integrity, then either replace surface boards or add new square footage. It’s faster, more cost-effective, and just as custom as a brand-new build — minus the waste.
Keep the Frame. Upgrade Everything Else.
Re-decking projects include full surface board removal, inspection, and resurfacing with your choice of wood or composite. Extensions include footings, framing, new joists, and seamless blending into the old structure. We also replace railings, stairs, and fascia as needed. You’ll get a deck that looks brand new — at a fraction of the time and cost.

Add Space Without Breaking the Bank
Need more space for seating, dining, or entertaining? We build seamless deck extensions that match your existing structure — in layout, height, and finish. Whether you're hosting bigger crowds or just want a grill zone that doesn't crowd the furniture, an extension adds flexibility without requiring a full replacement. We pour new footings, frame to code, and match materials so it all feels like one complete deck.

Out With the Old. In With the Better.
Splintered boards, warped wood, and faded stains don’t always mean your deck is done. If the frame is solid, re-decking gives you a brand-new surface with less mess and faster results. We remove all old boards, check the structure, then install fresh decking with hidden fasteners and clean finishes. It’s the same great deck — just better.
Poorly planned deck add-ons often feel like awkward afterthoughts. We design extensions that tie into your existing layout — matching board direction, railing style, elevation, and finish. Whether you’re expanding a single level or adding a lower step-down platform, our team makes sure it all looks and feels intentional. You'll gain usable space without losing design flow.
