Expand and Refresh Your Outdoor Space

Deck Extensions & Re-Decking in South Dakota

Affordable Alternatives to Full Replacement

Why Choose Deck Extensions or Re-Decking?

If your current deck feels too small or worn but the frame is still solid, extensions and re-decking provide the perfect solution. We can expand your deck with additional square footage or replace surface boards with new cedar or composite materials. These services save money compared to full replacement while delivering a refreshed, durable deck.

Benefits of Extensions and Re-Decking

Cost-Effective Deck Upgrades

Many South Dakota homeowners are surprised to learn they don’t always need a new deck. If your structure is sound, re-decking allows us to replace boards with durable materials like composite or cedar, giving your space a modern look without rebuilding the frame. Deck extensions expand usable space for dining, lounging, or entertaining, and can include features like stairs, railings, or pergolas. With professional installation, your improved deck not only looks great but also meets safety codes and withstands the local climate.

Strong Builds for Harsh Climates

Weather-Resistant Re-Decking

South Dakota’s changing weather can cause boards to warp, fade, or rot over time. Our re-decking services use durable cedar and long-lasting composite materials designed to handle freezing winters and hot, humid summers. We secure every board with weather-resistant fasteners and reinforce connections for strength, ensuring your refreshed deck stands strong year after year.
