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.
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.

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.

Extending your deck creates space for outdoor kitchens, seating areas, or hot tubs. We design extensions that blend seamlessly with your existing structure while enhancing functionality and style. Options include multi-level platforms, custom railings, pergolas, and covered roofs. Every addition is tailored to your property and built to withstand South Dakota’s seasonal challenges.
Our licensed team inspects your existing structure before beginning any extension or re-decking project. This ensures safety and prevents hidden issues from resurfacing later. With years of hands-on experience, we deliver seamless results, whether we’re expanding a small backyard deck or re-surfacing a large multi-level structure. Every project includes warranties for added peace of mind.
